<h1>Email Class</h1>
<p>CodeIgniter's robust Email Class supports the following features:</p>
<ul>
<li>Multiple Protocols: Mail, Sendmail, and SMTP</li>
<li>Multiple recipients</li>
<li>CC and BCCs</li>
<li>HTML or Plaintext email</li>
<li>Attachments</li>
<li>Word wrapping</li>
<li>Priorities</li>
<li>BCC Batch Mode, enabling large email lists to be broken into small BCC batches.</li>
<li>Email Debugging tools</li>
</ul>
<h2>Sending Email</h2>
<p>Sending email is not only simple, but you can configure it on the fly or set your preferences in a config file.</p>
<p>Here is a basic example demonstrating how you might send email. Note: This example assumes you are sending the email from one of your
<a href="../general/controllers.html">controllers</a>.</p>
<code>$this->load->library('email');<br />
<br />
$this->email->from('your@your-site.com', 'Your Name');<br />
$this->email->to('someone@example.com'); <br />
$this->email->cc('another@another-example.com'); <br />
$this->email->bcc('them@their-example.com'); <br />
<br />
$this->email->subject('Email Test');<br />
$this->email->message('Testing the email class.'); <br />
<br />
$this->email->send();<br />
<br />
echo $this->email->print_debugger();</code>
<h2>Setting Email Preferences</h2>
<p>There are 17 different preferences available to tailor how your email messages are sent. You can either set them manually
as described here, or automatically via preferences stored in your config file, described below:</p>
<p>Preferences are set by passing an array of preference values to the email <dfn>initialize</dfn> function. Here is an example of how you might set some preferences:</p>
<code>$config['protocol'] = 'sendmail';<br />
$config['mailpath'] = '/usr/sbin/sendmail';<br />
$config['charset'] = 'iso-8859-1';<br />
$config['wordwrap'] = TRUE;<br />
<br />
$this->email->initialize($config);</code>
<p><strong>Note:</strong> Most of the preferences have default values that will be used if you do not set them.</p
><h3>Setting Email Preferences in a Config File</h3>
<p>If you prefer not to set preferences using the above method, you can instead put them into a config file.
Simply create a new file called the <var>email.php</var>, add the <var>$config</var>
array in that file. Then save the file at <var>config/email.php</var> and it will be used automatically. You
will NOT need to use the <dfn>$this->email->initialize()</dfn> function if you save your preferences in a config file.</p>
<h2>Email Preferences</h2>
<p>The following is a list of all the preferences that can be set when sending email.</p>

<h2>Email Function Reference</h2>
<h3>$this->email->from()</h3>
<p>Sets the email address and name of the person sending the email:</p>
<code>$this->email->from('<var>you@your-site.com</var>', '<var>Your Name</var>');</code>
<h3>$this->email->reply_to()</h3>
<p>Sets the reply-to address. If the information is not provided the information in the "from" function is used. Example:</p>
<code>$this->email->reply_to('<var>you@your-site.com</var>', '<var>Your Name</var>');</code>
<h3>$this->email->to()</h3>
<p>Sets the email address(s) of the recipient(s). Can be a single email, a comma-delimited list or an array:</p>
<code>$this->email->to('<var>someone@example.com</var>');</code>
<code>$this->email->to('<var>one@example.com</var>, <var>two@example.com</var>, <var>three@example.com</var>');</code>
<code>$list = array('<var>one@example.com</var>', '<var>two@example.com</var>', '<var>three@example.com</var>');<br />
<br />
$this->email->to(<var>$list</var>);</code>
<h3>$this->email->cc()</h3>
<p>Sets the CC email address(s). Just like the "to", can be a single email, a comma-delimited list or an array.</p>
<h3>$this->email->bcc()</h3>
<p>Sets the BCC email address(s). Just like the "to", can be a single email, a comma-delimited list or an array.</p>
<h3>$this->email->subject()</h3>
<p>Sets the email subject:</p>
<code>$this->email->subject('<var>This is my subject</var>');</code>
<h3>$this->email->message()</h3>
<p>Sets the email message body:</p>
<code>$this->email->message('<var>This is my message</var>');</code>
<h3>$this->email->set_alt_message()</h3>
<p>Sets the alternative email message body:</p>
<code>$this->email->set_alt_message('<var>This is the alternative message</var>');</code>
<p>This is an optional message string which can be used if you send HTML formatted email. It lets you specify an alternative
message with no HTML formatting which is added to the header string for people who do not accept HTML email.
If you do not set your own message CodeIgniter will extract the message from your HTML email and strip the tags.</p>
<h3>$this->email->clear()</h3>
<p>Initializes all the email variables to an empty state. This function is intended for use if you run the email sending function
in a loop, permitting the data to be reset between cycles.</p>
<code>foreach ($list as $name => $address)<br />
{<br />
$this->email->clear();<br /><br />
$this->email->to($address);<br />
$this->email->from('your@your-site.com');<br />
$this->email->subject('Here is your info '.$name);<br />
$this->email->message('Hi '.$name.' Here is the info you requested.');<br />
$this->email->send();<br />
}</code>
<p>If you set the parameter to TRUE any attachments will be cleared as well:</p>
<code>$this->email->clear(TRUE);</code>
<h3>$this->email->send()</h3>
<p>The Email sending function. Returns boolean TRUE or FALSE based on success or failure, enabling it to be used
conditionally:</p>
<code>if ( ! $this->email->send())<br />
{<br />
// Generate error<br />
}</code>
<h3>$this->email->attach()</h3>
<p>Enables you to send an attachment. Put the file path/name in the first parameter. Note: Use a file path, not a URL.
For multiple attachments use the function multiple times. For example:</p>
<code>$this->email->attach('/path/to/photo1.jpg');<br />
$this->email->attach('/path/to/photo2.jpg');<br />
$this->email->attach('/path/to/photo3.jpg');<br />
<br />
$this->email->send();</code>
<h3>$this->email->print_debugger()</h3>
<p>Returns a string containing any server messages, the email headers, and the email messsage. Useful for debugging.</p>
<h2>Overriding Word Wrapping</h2>
<p>If you have word wrapping enabled (recommended to comply with RFC 822) and you have a very long link in your email it can
get wrapped too, causing it to become un-clickable by the person receiving it. CodeIgniter lets you manually override
word wrapping within part of your message like this:</p>
<code>The text of your email that<br />
gets wrapped normally.<br />
<br />
<var>{unwrap}</var>http://www.example.com/a_long_link_that_should_not_be_wrapped.html<var>{/unwrap}</var><br />
<br />
More text that will be<br />
wrapped normally.</code>
<p>Place the item you do not want word-wrapped between: <var>{unwrap}</var> <var>{/unwrap}</var></p>

+<p>Sets the CC email address(s). Just like the "to", can be a single email, a comma-delimited list or an array.</p>
+
+<h3>$this->email->bcc()</h3>
+<p>Sets the BCC email address(s). Just like the "to", can be a single email, a comma-delimited list or an array.</p>
+
+
+<h3>$this->email->subject()</h3>
+<p>Sets the email subject:</p>
+<code>$this->email->subject('<var>This is my subject</var>');</code>
+
+<h3>$this->email->message()</h3>
+<p>Sets the email message body:</p>
+<code>$this->email->message('<var>This is my message</var>');</code>
+
+<h3>$this->email->set_alt_message()</h3>
+<p>Sets the alternative email message body:</p>
+<code>$this->email->set_alt_message('<var>This is the alternative message</var>');</code>
+
+<p>This is an optional message string which can be used if you send HTML formatted email. It lets you specify an alternative
+message with no HTML formatting which is added to the header string for people who do not accept HTML email.
+If you do not set your own message CodeIgniter will extract the message from your HTML email and strip the tags.</p>
+
+
+
+<h3>$this->email->clear()</h3>
+<p>Initializes all the email variables to an empty state. This function is intended for use if you run the email sending function
+in a loop, permitting the data to be reset between cycles.</p>
+<code>foreach ($list as $name => $address)<br />
+{<br />
+ $this->email->clear();<br /><br />
+
+ $this->email->to($address);<br />
+ $this->email->from('your@your-site.com');<br />
+ $this->email->subject('Here is your info '.$name);<br />
+ $this->email->message('Hi '.$name.' Here is the info you requested.');<br />
+ $this->email->send();<br />
+}</code>
+
+<p>If you set the parameter to TRUE any attachments will be cleared as well:</p>
+
+<code>$this->email->clear(TRUE);</code>
+
+
+<h3>$this->email->send()</h3>
+<p>The Email sending function. Returns boolean TRUE or FALSE based on success or failure, enabling it to be used
+conditionally:</p>
+
+<code>if ( ! $this->email->send())<br />
+{<br />
+ // Generate error<br />
+}</code>
+
+
+<h3>$this->email->attach()</h3>
+<p>Enables you to send an attachment. Put the file path/name in the first parameter. Note: Use a file path, not a URL.
+For multiple attachments use the function multiple times. For example:</p>
+
+<code>$this->email->attach('/path/to/photo1.jpg');<br />
+$this->email->attach('/path/to/photo2.jpg');<br />
+$this->email->attach('/path/to/photo3.jpg');<br />
+<br />
+$this->email->send();</code>
+
+
+<h3>$this->email->print_debugger()</h3>
+<p>Returns a string containing any server messages, the email headers, and the email messsage. Useful for debugging.</p>
+
+
+<h2>Overriding Word Wrapping</h2>
+
+<p>If you have word wrapping enabled (recommended to comply with RFC 822) and you have a very long link in your email it can
+get wrapped too, causing it to become un-clickable by the person receiving it. CodeIgniter lets you manually override
+word wrapping within part of your message like this:</p>
+
+<code>The text of your email that<br />
+gets wrapped normally.<br />
+<br />
+<var>{unwrap}</var>http://www.example.com/a_long_link_that_should_not_be_wrapped.html<var>{/unwrap}</var><br />
+<br />
+More text that will be<br />
+wrapped normally.</code>
+
+<p>Place the item you do not want word-wrapped between: <var>{unwrap}</var> <var>{/unwrap}</var></p>

<h1>HTML Table Class</h1>
<p>The Table Class provides functions that enable you to auto-generate HTML tables from arrays or database result sets.</p>
<h2>Initializing the Class</h2>
<p>Like most other classes in CodeIgniter, the Table class is initialized in your controller using the <dfn>$this->load->library</dfn> function:</p>
<code>$this->load->library('table');</code>
<p>Once loaded, the Table library object will be available using: <dfn>$this->table</dfn></p>
<h2>Examples</h2>
<p>Here is an example showing how you can create a table from a multi-dimensional array.
Note that the first array index will become the table heading (or you can set your own headings using the
<dfn>set_heading()</dfn> function described in the function reference below).</p>
<code>
$this->load->library('table');<br />
<br />
$data = array(<br />
array('Name', 'Color', 'Size'),<br />
array('Fred', 'Blue', 'Small'),<br />
array('Mary', 'Red', 'Large'),<br />
array('John', 'Green', 'Medium') <br />
);<br />
<br />
echo $this->table->generate($data);
</code>
<p>Here is an example of a table created from a database query result. The table class will automatically generate the
headings based on the table names (or you can set your own headings using the <dfn>set_heading()</dfn> function described
in the function reference below).</p>
<code>
$this->load->library('table');<br />
<br />
$query = $this->db->query("SELECT * FROM my_table");<br />
<br />
echo $this->table->generate($query);
</code>
<p>Here is an example showing how you might create a table using discreet parameters:</p>
<code>
$this->load->library('table');<br />
<br />
$this->table->set_heading('Name', 'Color', 'Size');<br />
<br />
$this->table->add_row('Fred', 'Blue', 'Small');<br />
$this->table->add_row('Mary', 'Red', 'Large');<br />
$this->table->add_row('John', 'Green', 'Medium');<br />
<br />
echo $this->table->generate();
</code>
<p>Here is the same example, except instead of individual parameters, arrays are used:</p>
<code>
$this->load->library('table');<br />
<br />
$this->table->set_heading(array('Name', 'Color', 'Size'));<br />
<br />
$this->table->add_row(array('Fred', 'Blue', 'Small'));<br />
$this->table->add_row(array('Mary', 'Red', 'Large'));<br />
$this->table->add_row(array('John', 'Green', 'Medium'));<br />
<br />
echo $this->table->generate();
</code>
<h2>Changing the Look of Your Table</h2>
<p>The Table Class permits you to set a table template with which you can specify the design of your layout. Here is the template
prototype:</p>
<code>
$tmpl = array (<br />
'table_open' => '<table border="0" cellpadding="4" cellspacing="0">',<br />
<br />
'heading_row_start' => '<tr>',<br />
'heading_row_end' => '</tr>',<br />
'heading_cell_start' => '<th>',<br />
'heading_cell_end' => '</th>',<br />
<br />
'row_start' => '<tr>',<br />
'row_end' => '</tr>',<br />
'cell_start' => '<td>',<br />
'cell_end' => '</td>',<br />
<br />
'row_alt_start' => '<tr>',<br />
'row_alt_end' => '</tr>',<br />
'cell_alt_start' => '<td>',<br />
'cell_alt_end' => '</td>',<br />
<br />
'table_close' => '</table>'<br />
);<br />
<br />
$this->table->set_template($tmpl);
</code>
<p class="important"><strong>Note:</strong> You'll notice there are two sets of "row" blocks in the template. These permit you to create alternating row colors or design elements that alternate with each
iteration of the row data.</p>
<p>You are NOT required to submit a complete template. If you only need to change parts of the layout you can simply submit those elements.
In this example, only the table opening tag is being changed:</p>
<code>
$tmpl = array ( 'table_open' => '<table border="1" cellpadding="2" cellspacing="1" class="mytable">' );<br />
<br />
$this->table->set_template($tmpl);
</code>
<br />
<h1>Function Reference</h1>
<h2>$this->table->generate()</h2>
<p>Returns a string containing the generated table. Accepts an optional parameter which can be an array or a database result object.</p>
<h2>$this->table->set_caption()</h2>
<p>Permits you to add a caption to the table.</p>
<code>$this->table->set_caption('Colors');</code>
<h2>$this->table->set_heading()</h2>
<p>Permits you to set the table heading. You can submit an array or discreet params:</p>
<code>$this->table->set_heading('Name', 'Color', 'Size');</code>
<code>$this->table->set_heading(array('Name', 'Color', 'Size'));</code>
<h2>$this->table->add_row()</h2>
<p>Permits you to add a row to your table. You can submit an array or discreet params:</p>
<code>$this->table->add_row('Blue', 'Red', 'Green');</code>
<code>$this->table->add_row(array('Blue', 'Red', 'Green'));</code>
<h2>$this->table->make_columns()</h2>
<p>This function takes a one-dimensional array as input and creates
a multi-dimensional array with a depth equal to the number of
columns desired. This allows a single array with many elements to be
displayed in a table that has a fixed column count. Consider this example:</p>
<code>
$list = array('one', 'two', 'three', 'four', 'five', 'six', 'seven', 'eight', 'nine', 'ten', 'eleven', 'twelve');<br />
<br />
$new_list = $this->table->make_columns($list, 3);<br />
<br />
$this->table->generate($new_list);<br />
<br />
// Generates a table with this prototype<br />
<br />
<table border="0" cellpadding="4" cellspacing="0"><br />
<tr><br />
<td>one</td><td>two</td><td>three</td><br />
</tr><tr><br />
<td>four</td><td>five</td><td>six</td><br />
</tr><tr><br />
<td>seven</td><td>eight</td><td>nine</td><br />
</tr><tr><br />
<td>ten</td><td>eleven</td><td>twelve</td></tr><br />
</table></code>
<h2>$this->table->set_template()</h2>
<p>Permits you to set your template. You can submit a full or partial template.</p>
<code>
$tmpl = array ( 'table_open' => '<table border="1" cellpadding="2" cellspacing="1" class="mytable">' );<br />
<br />
$this->table->set_template($tmpl);
</code>
<h2>$this->table->set_empty()</h2>
<p>Let's you set a default value for use in any table cells that are empty. You might, for example, set a non-breaking space:</p>
<code>
$this->table->set_empty("&nbsp;");
</code>
<h2>$this->table->clear()</h2>
<p>Lets you clear the table heading and row data. If you need to show multiple tables with different data you should
to call this function after each table has been generated to empty the previous table information. Example:</p>
<code>
$this->load->library('table');<br />
<br />
$this->table->set_heading('Name', 'Color', 'Size');<br />
$this->table->add_row('Fred', 'Blue', 'Small');<br />
$this->table->add_row('Mary', 'Red', 'Large');<br />
$this->table->add_row('John', 'Green', 'Medium');<br />
<br />
echo $this->table->generate();<br />
<br />
<kbd>$this->table->clear();</kbd><br />
<br />
$this->table->set_heading('Name', 'Day', 'Delivery');<br />
$this->table->add_row('Fred', 'Wednesday', 'Express');<br />
$this->table->add_row('Mary', 'Monday', 'Air');<br />
$this->table->add_row('John', 'Saturday', 'Overnight');<br />
<br />
echo $this->table->generate();
</code>

+echo $this->table->generate();
+</code>
+
+<p>Here is the same example, except instead of individual parameters, arrays are used:</p>
+
+<code>
+$this->load->library('table');<br />
+<br />
+$this->table->set_heading(array('Name', 'Color', 'Size'));<br />
+<br />
+$this->table->add_row(array('Fred', 'Blue', 'Small'));<br />
+$this->table->add_row(array('Mary', 'Red', 'Large'));<br />
+$this->table->add_row(array('John', 'Green', 'Medium'));<br />
+<br />
+echo $this->table->generate();
+</code>
+
+
+<h2>Changing the Look of Your Table</h2>
+
+<p>The Table Class permits you to set a table template with which you can specify the design of your layout. Here is the template
+prototype:</p>
+
+<code>
+$tmpl = array (<br />
+ 'table_open' => '<table border="0" cellpadding="4" cellspacing="0">',<br />
+<br />
+ 'heading_row_start' => '<tr>',<br />
+ 'heading_row_end' => '</tr>',<br />
+ 'heading_cell_start' => '<th>',<br />
+ 'heading_cell_end' => '</th>',<br />
+<br />
+ 'row_start' => '<tr>',<br />
+ 'row_end' => '</tr>',<br />
+ 'cell_start' => '<td>',<br />
+ 'cell_end' => '</td>',<br />
+<br />
+ 'row_alt_start' => '<tr>',<br />
+ 'row_alt_end' => '</tr>',<br />
+ 'cell_alt_start' => '<td>',<br />
+ 'cell_alt_end' => '</td>',<br />
+<br />
+ 'table_close' => '</table>'<br />
+ );<br />
+
+<br />
+$this->table->set_template($tmpl);
+</code>
+
+<p class="important"><strong>Note:</strong> You'll notice there are two sets of "row" blocks in the template. These permit you to create alternating row colors or design elements that alternate with each
+iteration of the row data.</p>
+
+<p>You are NOT required to submit a complete template. If you only need to change parts of the layout you can simply submit those elements.
+In this example, only the table opening tag is being changed:</p>
+
+<code>
+$tmpl = array ( 'table_open' => '<table border="1" cellpadding="2" cellspacing="1" class="mytable">' );<br />
+
+<br />
+$this->table->set_template($tmpl);
+</code>
+
+<br />
+<h1>Function Reference</h1>
+
+<h2>$this->table->generate()</h2>
+<p>Returns a string containing the generated table. Accepts an optional parameter which can be an array or a database result object.</p>
+
+<h2>$this->table->set_caption()</h2>
+
+<p>Permits you to add a caption to the table.</p>
+
+<code>$this->table->set_caption('Colors');</code>
+
+<h2>$this->table->set_heading()</h2>
+
+<p>Permits you to set the table heading. You can submit an array or discreet params:</p>
+
+<code>$this->table->set_heading('Name', 'Color', 'Size');</code>
+<code>$this->table->set_heading(array('Name', 'Color', 'Size'));</code>
+
+<h2>$this->table->add_row()</h2>
+
+<p>Permits you to add a row to your table. You can submit an array or discreet params:</p>
+
+<code>$this->table->add_row('Blue', 'Red', 'Green');</code>
+<code>$this->table->add_row(array('Blue', 'Red', 'Green'));</code>
+
+
+<h2>$this->table->make_columns()</h2>
+
+<p>This function takes a one-dimensional array as input and creates
+a multi-dimensional array with a depth equal to the number of
+columns desired. This allows a single array with many elements to be
+displayed in a table that has a fixed column count. Consider this example:</p>
+
+<code>
+$list = array('one', 'two', 'three', 'four', 'five', 'six', 'seven', 'eight', 'nine', 'ten', 'eleven', 'twelve');<br />
+<br />
+$new_list = $this->table->make_columns($list, 3);<br />
+<br />
+$this->table->generate($new_list);<br />
+<br />
+// Generates a table with this prototype<br />
+<br />
+<table border="0" cellpadding="4" cellspacing="0"><br />
+<tr><br />
+<td>one</td><td>two</td><td>three</td><br />
+</tr><tr><br />
+<td>four</td><td>five</td><td>six</td><br />
+</tr><tr><br />
+<td>seven</td><td>eight</td><td>nine</td><br />
+</tr><tr><br />
+<td>ten</td><td>eleven</td><td>twelve</td></tr><br />
+</table></code>
+
+
+
+<h2>$this->table->set_template()</h2>
+
+<p>Permits you to set your template. You can submit a full or partial template.</p>
+
+<code>
+$tmpl = array ( 'table_open' => '<table border="1" cellpadding="2" cellspacing="1" class="mytable">' );<br />
+
+<br />
+$this->table->set_template($tmpl);
+</code>
+
+
+<h2>$this->table->set_empty()</h2>
+
+<p>Let's you set a default value for use in any table cells that are empty. You might, for example, set a non-breaking space:</p>
+
+<code>
+$this->table->set_empty("&nbsp;");
+</code>
+
+<h2>$this->table->clear()</h2>
+
+<p>Lets you clear the table heading and row data. If you need to show multiple tables with different data you should
+to call this function after each table has been generated to empty the previous table information. Example:</p>
+
+<code>
+$this->load->library('table');<br />
+<br />
+$this->table->set_heading('Name', 'Color', 'Size');<br />
+$this->table->add_row('Fred', 'Blue', 'Small');<br />
+$this->table->add_row('Mary', 'Red', 'Large');<br />
+$this->table->add_row('John', 'Green', 'Medium');<br />
+<br />
+echo $this->table->generate();<br />
+<br />
+<kbd>$this->table->clear();</kbd><br />
+<br />
+$this->table->set_heading('Name', 'Day', 'Delivery');<br />
+$this->table->add_row('Fred', 'Wednesday', 'Express');<br />
+$this->table->add_row('Mary', 'Monday', 'Air');<br />
+$this->table->add_row('John', 'Saturday', 'Overnight');<br />
+<br />
+echo $this->table->generate();
+</code>

<h1>URI Class</h1>
<p>The URI Class provides functions that help you retrieve information from your URI strings. If you use URI routing, you can
also retrieve information about the re-routed segments.</p>
<p class="important"><strong>Note:</strong> This class is initialized automatically by the system so there is no need to do it manually.</p>
<h2>$this->uri->segment(<var>n</var>)</h2>
<p>Permits you to retrieve a specific segment. Where <var>n</var> is the segment number you wish to retrieve.
Segments are numbered from left to right. For example, if your full URL is this:</p>
<code>http://www.your-site.com/index.php/news/local/metro/crime_is_up</code>
<p>The segment numbers would be this:</p>
<ol>
<li>news</li>
<li>local</li>
<li>metro</li>
<li>crime_is_up</li>
</ol>
<p>By default the function returns FALSE (boolean) if the segment does not exist. There is an optional second parameter that
permits you to set your own default value if the segment is missing.
For example, this would tell the function to return the number zero in the event of failure:</p>
<code>$product_id = $this->uri->segment(3, 0);</code>
<p>It helps avoid having to write code like this:</p>
<code>if ($this->uri->segment(3) === FALSE)<br />
{<br />
$product_id = 0;<br />
}<br />
else<br />
{<br />
$product_id = $this->uri->segment(3);<br />
}<br />
</code>
<h2>$this->uri->rsegment(<var>n</var>)</h2>
<p>This function is identical to the previous one, except that it lets you retrieve a specific segment from your
re-routed URI in the event you are using CodeIgniter's <a href="../general/routing.html">URI Routing</a> feature.</p>
<h2>$this->uri->slash_segment(<var>n</var>)</h2>
<p>This function is almost identical to <dfn>$this->uri->segment()</dfn>, except it adds a trailing and/or leading slash based on the second
parameter. If the parameter is not used, a trailing slash added. Examples:</p>
<code>$this->uri->slash_segment(<var>3</var>);<br />
$this->uri->slash_segment(<var>3</var>, 'leading');<br />
$this->uri->slash_segment(<var>3</var>, 'both');</code>
<p>Returns:</p>
<ol>
<li>segment/</li>
<li>/segment</li>
<li>/segment/</li>
</ol>
<h2>$this->uri->slash_rsegment(<var>n</var>)</h2>
<p>This function is identical to the previous one, except that it lets you add slashes a specific segment from your
re-routed URI in the event you are using CodeIgniter's <a href="../general/routing.html">URI Routing</a> feature.</p>
<h2>$this->uri->uri_to_assoc(<var>n</var>)</h2>
<p>This function lets you turn URI segments into and associative array of key/value pairs. Consider this URI:</p>
<code>index.php/user/search/name/joe/location/UK/gender/male</code>
<p>Using this function you can turn the URI into an associative array with this prototype:</p>
<code>[array]<br />
(<br />
'name' => 'joe'<br />
'location' => 'UK'<br />
'gender' => 'male'<br />
)</code>
<p>The first parameter of the function lets you set an offset. By default it is set to <kbd>3</kbd> since your
URI will normally contain a controller/function in the first and second segments. Example:</p>
<code>
$array = $this->uri->uri_to_assoc(3);<br />
<br />
echo $array['name'];
</code>
<p>The second parameter lets you set default key names, so that the array returned by the function will always contain expected indexes, even if missing from the URI. Example:</p>
<code>
$default = array('name', 'gender', 'location', 'type', 'sort');<br />
<br />
$array = $this->uri->uri_to_assoc(3, $default);</code>
<p>If the URI does not contain a value in your default, an array index will be set to that name, with a value of FALSE.</p>
<p>Lastly, if a corresponding value is not found for a given key (if there is an odd number of URI segments) the value will be set to FALSE (boolean).</p>
<h2>$this->uri->ruri_to_assoc(<var>n</var>)</h2>
<p>This function is identical to the previous one, except that it creates an associative array using the
re-routed URI in the event you are using CodeIgniter's <a href="../general/routing.html">URI Routing</a> feature.</p>
<h2>$this->uri->assoc_to_uri()</h2>
<p>Takes an associative array as input and generates a URI string from it. The array keys will be included in the string. Example:</p>
<code>$array = array('product' => 'shoes', 'size' => 'large', 'color' => 'red');<br />
<br />
$str = $this->uri->assoc_to_uri($array);<br />
<br />
// Produces: product/shoes/size/large/color/red
</code>
<h2>$this->uri->uri_string()</h2>
<p>Returns a string with the complete URI. For example, if this is your full URL:</p>
<code>http://www.your-site.com/index.php/news/local/345</code>
<p>The function would return this:</p>
<code>/news/local/345</code>
<h2>$this->uri->ruri_string(<var>n</var>)</h2>
<p>This function is identical to the previous one, except that it returns the
re-routed URI in the event you are using CodeIgniter's <a href="../general/routing.html">URI Routing</a> feature.</p>
<h2>$this->uri->total_segments()</h2>
<p>Returns the total number of segments.</p>
<h2>$this->uri->total_rsegments(<var>n</var>)</h2>
<p>This function is identical to the previous one, except that it returns the total number of segments in your
re-routed URI in the event you are using CodeIgniter's <a href="../general/routing.html">URI Routing</a> feature.</p>
<h2>$this->uri->segment_array()</h2>
<p>Returns an array containing the URI segments. For example:</p>
<code>
$segs = $this->uri->segment_array();<br />
<br />
foreach ($segs as $segment)<br />
{<br />
echo $segment;<br />
echo '<br />';<br />
}</code>
<h2>$this->uri->rsegment_array(<var>n</var>)</h2>
<p>This function is identical to the previous one, except that it returns the array of segments in your
re-routed URI in the event you are using CodeIgniter's <a href="../general/routing.html">URI Routing</a> feature.

<h1>User Agent Class</h1>
<p>The User Agent Class provides functions that help identify information about the browser, mobile device, or robot visiting your site.
In addition you can get referrer information as well as language and supported character-set information.</p>
<h2>Initializing the Class</h2>
<p>Like most other classes in CodeIgniter, the User Agent class is initialized in your controller using the <dfn>$this->load->library</dfn> function:</p>
<code>$this->load->library('user_agent');</code>
<p>Once loaded, the object will be available using: <dfn>$this->agent</dfn></p>
<h2>User Agent Definitions</h2>
<p>The user agent name definitions are located in a config file located at: <dfn>application/config/user_agents.php</dfn>. You may add items to the
various user agent arrays if needed.</p>
<h2>Example</h2>
<p>When the User Agent class is initialized it will attempt to determine whether the user agent browsing your site is
a web browser, a mobile device, or a robot. It will also gather the platform information if it is available.</p>
<code>
$this->load->library('user_agent');<br />
<br />
if ($this->agent->is_browser())<br />
{<br />
$agent = $this->agent->browser().' '.$this->agent->version();<br />
}<br />
elseif ($this->agent->is_robot())<br />
{<br />
$agent = $this->agent->robot();<br />
}<br />
elseif ($this->agent->is_mobile())<br />
{<br />
$agent = $this->agent->mobile();<br />
}<br />
else<br />
{<br />
$agent = 'Unidentified User Agent';<br />
}<br />
<br />
echo $agent;<br />
<br />
echo $this->agent->platform(); // Platform info (Windows, Linux, Mac, etc.)
</code>
<h1>Function Reference</h1>
<h2>$this->agent->is_browser()</h2>
<p>Returns TRUE/FALSE (boolean) if the user agent is a known web browser.</p>
<h2>$this->agent->is_mobile()</h2>
<p>Returns TRUE/FALSE (boolean) if the user agent is a known mobile device.</p>
<h2>$this->agent->is_robot()</h2>
<p>Returns TRUE/FALSE (boolean) if the user agent is a known robot.</p>
<p class="important"><strong>Note:</strong> The user agent library only contains the most common robot
definitions. It is not a complete list of bots. There are hundreds of them so searching for each one would not be
very efficient. If you find that some bots that commonly visit your site are missing from the list you can add them to your
<dfn>application/config/user_agents.php</dfn> file.</p>
<h2>$this->agent->is_referral()</h2>
<p>Returns TRUE/FALSE (boolean) if the user agent was referred from another site.</p>
<h2>$this->agent->browser()</h2>
<p>Returns a string containing the name of the web browser viewing your site.</p>
<h2>$this->agent->version()</h2>
<p>Returns a string containing the version number of the web browser viewing your site.</p>
<h2>$this->agent->mobile()</h2>
<p>Returns a string containing the name of the mobile device viewing your site.</p>
<h2>$this->agent->robot()</h2>
<p>Returns a string containing the name of the robot viewing your site.</p>
<h2>$this->agent->platform()</h2>
<p>Returns a string containing the platform viewing your site (Linux, Windows, OS X, etc.).</p>
<h2>$this->agent->referrer()</h2>
<p>The referrer, if the user agent was referred from another site. Typically you'll test for this as follows:</p>
<code> if ($this->agent->is_referral())<br />
{<br />
echo $this->agent->referrer();<br />
}</code>
<h2>$this->agent->agent_string()</h2>
<p>Returns a string containing the full user agent string. Typically it will be something like this:</p>
<code>Mozilla/5.0 (Macintosh; U; Intel Mac OS X; en-US; rv:1.8.0.4) Gecko/20060613 Camino/1.0.2</code>
<h2>$this->agent->accept_lang()</h2>
<p>Lets you determine if the user agent accepts a particular language. Example:</p>
<code>if ($this->agent->accept_lang('en'))<br />
{<br />
echo 'You accept English!';<br />
}</code>
<p class="important"><strong>Note:</strong> This function is not typically very reliable
since some browsers do not provide language info, and even among those that do, it is not always accurate. </p>
<h2>$this->agent->accept_charset()</h2>
<p>Lets you determine if the user agent accepts a particular character set. Example:</p>
<code>if ($this->agent->accept_charset('utf-8'))<br />
{<br />
echo 'You browser supports UTF-8!';<br />
}</code>
<p class="important"><strong>Note:</strong> This function is not typically very reliable
since some browsers do not provide character-set info, and even among those that do, it is not always accurate. </p>

<h1>XML-RPC and XML-RPC Server Classes</h1>
<p>CodeIgniter's XML-RPC classes permit you to send requests to another server, or set up
your own XML-RPC server to receive requests.</p>
<h2>What is XML-RPC?</h2>
<p>Quite simply it is a way for two computers to communicate over the internet using XML.
One computer, which we will call the <dfn>client</dfn>, sends an XML-RPC <strong>request</strong> to
another computer, which we will call the <dfn>server</dfn>. Once the server receives and processes the request it
will send back a <strong>response</strong> to the client.</p>
<p>For example, using the MetaWeblog API, an XML-RPC Client (usually a desktop publishing tool) will
send a request to an XML-RPC Server running on your site. This request might be a new weblog entry
being sent for publication, or it could be a request for an existing entry for editing.
When the XML-RPC Server receives this request it will examine it to determine which class/method should be called to process the request.
Once processed, the server will then send back a response message.</p>
<p>For detailed specifications, you can visit the <a href="http://www.xmlrpc.com/">XML-RPC</a> site.</p>
<h2>Initializing the Class</h2>
<p>Like most other classes in CodeIgniter, the XML-RPC and XML-RPCS classes are initialized in your controller using the <dfn>$this->load->library</dfn> function:</p>
<p>To load the XML-RPC class you will use:</p>
<code>$this->load->library('xmlrpc');</code>
<p>Once loaded, the xml-rpc library object will be available using: <dfn>$this->xmlrpc</dfn></p>
<p>To load the XML-RPC Server class you will use:</p>
<code>
$this->load->library('xmlrpc');<br />
$this->load->library('xmlrpcs');
</code>
<p>Once loaded, the xml-rpcs library object will be available using: <dfn>$this->xmlrpcs</dfn></p>
<p class="important"><strong>Note:</strong> When using the XML-RPC Server class you must load BOTH the XML-RPC class and the XML-RPC Server class.</p>
<h2>Sending XML-RPC Requests</h2>
<p>To send a request to an XML-RPC server you must specify the following information:</p>
<ul>
<li>The URL of the server</li>
<li>The method on the server you wish to call</li>
<li>The <em>request</em> data (explained below).</li>
</ul>
<p>Here is a basic example that sends a simple Weblogs.com ping to the <a href="http://pingomatic.com/">Ping-o-Matic</a></p>
<code>$this->load->library('xmlrpc');<br />
<br />
$this->xmlrpc->server('http://rpc.pingomatic.com/', 80);<br />
$this->xmlrpc->method('weblogUpdates.ping');<br />
<br />
$request = array('My Photoblog', 'http://www.my-site.com/photoblog/');<br />
$this->xmlrpc->request($request);<br />
<br />
if ( ! $this->xmlrpc->send_request())<br />
{<br />
echo $this->xmlrpc->display_error();<br />
}</code>
<h3>Explanation</h3>
<p>The above code initializes the XML-RPC class, sets the server URL and method to be called (weblogUpdates.ping). The
request (in this case, the title and URL of your site) is placed into an array for transportation, and
compiled using the request() function.
Lastly, the full request is sent. If the <dfn>send_request()</dfn> method returns false we will display the error message
sent back from the XML-RPC Server.</p>
<h2>Anatomy of a Request</h2>
<p>An XML-RPC <dfn>request</dfn> is simply the data you are sending to the XML-RPC server. Each piece of data in a request
is referred to as a <dfn>request parameter</dfn>. The above example has two parameters:
The URL and title of your site. When the XML-RPC server receives your request, it will look for parameters it requires.</p>
<p>Request parameters must be placed into an array for transportation, and each parameter can be one
of seven data types (strings, numbers, dates, etc.). If your parameters are something other than strings
you will have to include the data type in the request array.</p>
<p>Here is an example of a simple array with three parameters:</p>
<code>$request = array('John', 'Doe', 'www.some-site.com');<br />
$this->xmlrpc->request($request);</code>
<p>If you use data types other than strings, or if you have several different data types, you will place
each parameter into its own array, with the data type in the second position:</p>
<code>
$request = array (<br />
array('John', 'string'),<br />
array('Doe', 'string'),<br />
array(FALSE, 'boolean'),<br />
array(12345, 'int')<br />
);
<br />
$this->xmlrpc->request($request);</code>
The <a href="#datatypes">Data Types</a> section below has a full list of data types.
<h2>Creating an XML-RPC Server</h2>
<p>An XML-RPC Server acts as a traffic cop of sorts, waiting for incoming requests and redirecting them to the
appropriate functions for processing.</p>
<p>To create your own XML-RPC server involves initializing the XML-RPC Server class in your controller where you expect the incoming
request to appear, then setting up an array with mapping instructions so that incoming requests can be sent to the appropriate
class and method for processing.</p>
<p>Here is an example to illustrate:</p>
<code>
$this->load->library('xmlrpc');<br />
$this->load->library('xmlrpcs');<br />
<br />
$config['functions']['<var>new_post</var>'] = array('function' => '<dfn>My_blog.new_entry</dfn>');<br />
$config['functions']['<var>update_post</var>'] = array('function' => '<dfn>My_blog.update_entry</dfn>');<br />
<br />
$this->xmlrpcs->initialize($config);<br />
$this->xmlrpcs->serve();</code>
<p>The above example contains an array specifying two method requests that the Server allows.
The allowed methods are on the left side of the array. When either of those are received, they will be mapped to the class and method on the right.</p>
<p>In other words, if an XML-RPC Client sends a request for the <var>new_post</var> method, your
server will load the <dfn>My_blog</dfn> class and call the <dfn>new_entry</dfn> function.
If the request is for the <var>update_post</var> method, your
server will load the <dfn>My_blog</dfn> class and call the <dfn>update_entry</dfn> function.</p>
<p>The function names in the above example are arbitrary. You'll decide what they should be called on your server,
or if you are using standardized APIs, like the Blogger or MetaWeblog API, you'll use their function names.</p>
<h2>Processing Server Requests</h2>
<p>When the XML-RPC Server receives a request and loads the class/method for processing, it will pass
an object to that method containing the data sent by the client.</p>
<p>Using the above example, if the <var>new_post</var> method is requested, the server will expect a class
to exist with this prototype:</p>
<code>class <kbd>My_blog</kbd> extends Controller {<br />
<br />
function <kbd>new_post</kbd>(<var>$request</var>)<br />
{<br />
<br />
}<br />
}
</code>
<p>The <var>$request</var> variable is an object compiled by the Server, which contains the data sent by the XML-RPC Client.
Using this object you will have access to the <em>request parameters</em> enabling you to process the request. When
you are done you will send a <dfn>Response</dfn> back to the Client.</p>
<p>Below is a real-world example, using the Blogger API. One of the methods in the Blogger API is <dfn>getUserInfo()</dfn>.
Using this method, an XML-RPC Client can send the Server a username and password, in return the Server sends
back information about that particular user (nickname, user ID, email address, etc.). Here is how the processing
function might look:</p>
<code>class <kbd>My_blog</kbd> extends Controller {<br />
<br />
function <kbd>getUserInfo</kbd>(<var>$request</var>)<br />
{<br />
$username = 'smitty';<br />
$password = 'secretsmittypass';<br /><br />
$this->load->library('xmlrpc');<br />
<br />
$parameters = $request->output_parameters();<br />
<br />
if ($parameters['1'] != $username AND $parameters['2'] != $password)<br />
{<br />
return $this->xmlrpc->send_error_message('100', 'Invalid Access');<br />
}<br />
<br />
$response = array(array('nickname' => array('Smitty','string'),<br />
'userid' => array('99','string'),<br />
'url' => array('http://yoursite.com','string'),<br />
'email' => array('jsmith@yoursite.com','string'),<br />
'lastname' => array('Smith','string'),<br />
'firstname' => array('John','string')<br />
),<br />
'struct');<br />
<br />
return $this->xmlrpc->send_response($response);<br />
}<br />
}
</code>
<h3>Notes:</h3>
<p>The <dfn>output_parameters()</dfn> function retrieves an indexed array corresponding to the request parameters sent by the client.
In the above example, the output parameters will be the username and password.</p>
<p>If the username and password sent by the client were not valid, and error message is returned using <dfn>send_error_message()</dfn>.</p>
<p>If the operation was successful, the client will be sent back a response array containing the user's info.</p>
<h2>Formatting a Response</h2>
<p>Similar to <em>Requests</em>, <em>Responses</em> must be formatted as an array. However, unlike requests, a response is an array
<strong>that contains a single item</strong>. This item can be an array with several additional arrays, but there
can be only one primary array index. In other words, the basic prototype is this:</p>
<code>$response = array('Response data', 'array');</code>
<p>Responses, however, usually contain multiple pieces of information. In order to accomplish this we must put the response into its own
array so that the primary array continues to contain a single piece of data. Here's an example showing how this might be accomplished:</p>
<code>
$response = array (<br />
array(<br />
'first_name' => array('John', 'string'),<br />
'last_name' => array('Doe', 'string'),<br />
'member_id' => array(123435, 'int'),<br />
'todo_list' => array(array('clean house', 'call mom', 'water plants'), 'array'),<br />
),<br />
'struct'<br />
);
</code>
<p class="important">Notice that the above array is formatted as a <dfn>struct</dfn>. This is the most common data type for responses.</p>
<p>As with Requests, a response can be on of the seven data types listed in the <a href="#datatypes">Data Types</a> section.</p>
<h2>Sending an Error Response</h2>
<p>If you need to send the client an error response you will use the following:</p>
<code>return $this->xmlrpc->send_error_message('123', 'Requested data not available');</code>
<p>The first parameter is the error number while the second parameter is the error message.</p>
<h2>Creating Your Own Client and Server</h2>
<p>To help you understand everything we've covered thus far, let's create a couple controllers that act as
XML-RPC Client and Server. You'll use the Client to send a request to the Server and receive a response.</p>
<h3>The Client</h3>
<p>Using a text editor, create a controller called <dfn>xmlrpc_client.php</dfn>.
In it, place this code and save it to your <samp>applications/controllers/</samp> folder:</p>
<textarea class="textarea" style="width:100%" cols="50" rows="32"><?php
class Xmlrpc_client extends Controller {
function index()
{
$this->load->helper('url');
$server_url = site_url('xmlrpc_server');
$this->load->library('xmlrpc');
$this->xmlrpc->server($server_url, 80);
$this->xmlrpc->method('Greetings');
$request = array('How is it going?');
$this->xmlrpc->request($request);
if ( ! $this->xmlrpc->send_request())
{
echo $this->xmlrpc->display_error();
}
else
{
echo '<pre>';
print_r($this->xmlrpc->display_response());
echo '</pre>';
}
}
}
?></textarea>
<p>Note: In the above code we are using a "url helper". You can find more information in the <a href="../general/helpers.html">Helpers Functions</a> page.</p>
<h3>The Server</h3>
<p>Using a text editor, create a controller called <dfn>xmlrpc_server.php</dfn>.
In it, place this code and save it to your <samp>applications/controllers/</samp> folder:</p>
<textarea class="textarea" style="width:100%" cols="50" rows="30"><?php
class Xmlrpc_server extends Controller {
function index()
{
$this->load->library('xmlrpc');
$this->load->library('xmlrpcs');
$config['functions']['Greetings'] = array('function' => 'Xmlrpc_server.process');
$this->xmlrpcs->initialize($config);
$this->xmlrpcs->serve();
}
function process($request)
{
$parameters = $request->output_parameters();
$response = array(
array(
'you_said' => $parameters['0'],
'i_respond' => 'Not bad at all.'),
'struct');
return $this->xmlrpc->send_response($response);
}
}
?></textarea>
<h3>Try it!</h3>
<p>Now visit the your site using a URL similar to this:</p>
<code>www.your-site.com/index.php/<var>xmlrpc_client</var>/</code>
<p>You should now see the message you sent to the server, and its response back to you.</p>
<p>The client you created sends a message ("How's is going?") to the server, along with a reqest for the "Greetings" method.
The Server receives the request and maps it to the "process" function, where a response is sent back.</p>
<p> </p>
<h1>XML-RPC Function Reference</h1>
<h2>$this->xmlrpc->server()</h2>
<p>Sets the URL and port number of the server to which a request is to be sent:</p>
<code>$this->xmlrpc->server('http://www.sometimes.com/pings.php', 80);</code>
<h2>$this->xmlrpc->timeout()</h2>
<p>Set a time out period (in seconds) after which the request will be canceled:</p>
<code>$this->xmlrpc->timeout(6);</code>
<h2>$this->xmlrpc->method()</h2>
<p>Sets the method that will be requested from the XML-RPC server:</p>
<code>$this->xmlrpc->method('<var>method</var>');</code>
<p>Where <var>method</var> is the name of the method.</p>
<h2>$this->xmlrpc->request()</h2>
<p>Takes an array of data and builds request to be sent to XML-RPC server:</p>
<code>$request = array(array('My Photoblog', 'string'), 'http://www.yoursite.com/photoblog/');<br />
$this->xmlrpc->request($request);</code>
<h2>$this->xmlrpc->send_request()</h2>
<p>The request sending function. Returns boolean TRUE or FALSE based on success for failure, enabling it to be used conditionally.</p>
<h2>$this->xmlrpc->set_debug(TRUE);</h2>
<p>Enables debugging, which will display a variety of information and error data helpful during development.</p>
<h2>$this->xmlrpc->display_error()</h2>
<p>Returns an error message as a string if your request failed for some reason.</p>
<code>echo $this->xmlrpc->display_error();</code>
<h2>$this->xmlrpc->display_response()</h2>
<p>Returns the response from the remote server once request is received. The response will typically be an associative array.</p>
<code>$this->xmlrpc->display_response();</code>
<h2>$this->xmlrpc->send_error_message()</h2>
<p>This function lets you send an error message from your server to the client. First parameter is the error number while the second parameter
is the error message.</p>
<code>return $this->xmlrpc->send_error_message('123', 'Requested data not available');</code>
<h2>$this->xmlrpc->send_response()</h2>
<p>Lets you send the response from your server to the client. An array of valid data values must be sent with this method.</p>
<code>$response = array(<br />
array(<br />
'flerror' => array(FALSE, 'boolean'),<br />
'message' => "Thanks for the ping!")<br />
)<br />
'struct');<br />
return $this->xmlrpc->send_response($response);</code>
<a name="datatypes"></a>
<h2>Data Types</h2>
<p>According to the <a href="http://www.xmlrpc.com/spec">XML-RPC spec</a> there are seven types
of values that you can send via XML-RPC:</p>
<ul>
<li><em>int</em> or <em>i4</em></li>
<li><em>boolean</em></li>
<li><em>string</em></li>
<li><em>double</em></li>
<li><em>dateTime.iso8601</em></li>
<li><em>base64</em></li>
<li><em>struct</em> (contains array of values)</li>
<li><em>array</em> (contains array of values)</li>
</ul>

+<h1>XML-RPC and XML-RPC Server Classes</h1>
+
+
+<p>CodeIgniter's XML-RPC classes permit you to send requests to another server, or set up
+your own XML-RPC server to receive requests.</p>
+
+
+<h2>What is XML-RPC?</h2>
+
+<p>Quite simply it is a way for two computers to communicate over the internet using XML.
+One computer, which we will call the <dfn>client</dfn>, sends an XML-RPC <strong>request</strong> to
+another computer, which we will call the <dfn>server</dfn>. Once the server receives and processes the request it
+will send back a <strong>response</strong> to the client.</p>
+
+<p>For example, using the MetaWeblog API, an XML-RPC Client (usually a desktop publishing tool) will
+send a request to an XML-RPC Server running on your site. This request might be a new weblog entry
+being sent for publication, or it could be a request for an existing entry for editing.
+
+When the XML-RPC Server receives this request it will examine it to determine which class/method should be called to process the request.
+Once processed, the server will then send back a response message.</p>
+
+<p>For detailed specifications, you can visit the <a href="http://www.xmlrpc.com/">XML-RPC</a> site.</p>
+
+<h2>Initializing the Class</h2>
+
+<p>Like most other classes in CodeIgniter, the XML-RPC and XML-RPCS classes are initialized in your controller using the <dfn>$this->load->library</dfn> function:</p>
+
+<p>To load the XML-RPC class you will use:</p>
+<code>$this->load->library('xmlrpc');</code>
+<p>Once loaded, the xml-rpc library object will be available using: <dfn>$this->xmlrpc</dfn></p>
+
+<p>To load the XML-RPC Server class you will use:</p>
+<code>
+$this->load->library('xmlrpc');<br />
+$this->load->library('xmlrpcs');
+</code>
+<p>Once loaded, the xml-rpcs library object will be available using: <dfn>$this->xmlrpcs</dfn></p>
+
+<p class="important"><strong>Note:</strong> When using the XML-RPC Server class you must load BOTH the XML-RPC class and the XML-RPC Server class.</p>
+
+
+
+<h2>Sending XML-RPC Requests</h2>
+
+<p>To send a request to an XML-RPC server you must specify the following information:</p>
+
+<ul>
+<li>The URL of the server</li>
+<li>The method on the server you wish to call</li>
+<li>The <em>request</em> data (explained below).</li>
+</ul>
+
+<p>Here is a basic example that sends a simple Weblogs.com ping to the <a href="http://pingomatic.com/">Ping-o-Matic</a></p>
+
+
+<code>$this->load->library('xmlrpc');<br />
+<br />
+$this->xmlrpc->server('http://rpc.pingomatic.com/', 80);<br />
+$this->xmlrpc->method('weblogUpdates.ping');<br />
+
+<br />
+$request = array('My Photoblog', 'http://www.my-site.com/photoblog/');<br />
+$this->xmlrpc->request($request);<br />
+<br />
+if ( ! $this->xmlrpc->send_request())<br />
+{<br />
+ echo $this->xmlrpc->display_error();<br />
+}</code>
+
+<h3>Explanation</h3>
+
+<p>The above code initializes the XML-RPC class, sets the server URL and method to be called (weblogUpdates.ping). The
+request (in this case, the title and URL of your site) is placed into an array for transportation, and
+compiled using the request() function.
+Lastly, the full request is sent. If the <dfn>send_request()</dfn> method returns false we will display the error message
+sent back from the XML-RPC Server.</p>
+
+<h2>Anatomy of a Request</h2>
+
+<p>An XML-RPC <dfn>request</dfn> is simply the data you are sending to the XML-RPC server. Each piece of data in a request
+is referred to as a <dfn>request parameter</dfn>. The above example has two parameters:
+The URL and title of your site. When the XML-RPC server receives your request, it will look for parameters it requires.</p>
+
+<p>Request parameters must be placed into an array for transportation, and each parameter can be one
+of seven data types (strings, numbers, dates, etc.). If your parameters are something other than strings
+you will have to include the data type in the request array.</p>
+
+<p>Here is an example of a simple array with three parameters:</p>
+
+<code>$request = array('John', 'Doe', 'www.some-site.com');<br />
+$this->xmlrpc->request($request);</code>
+
+<p>If you use data types other than strings, or if you have several different data types, you will place
+each parameter into its own array, with the data type in the second position:</p>
+
+<code>
+$request = array (<br />
+ array('John', 'string'),<br />
+ array('Doe', 'string'),<br />
+ array(FALSE, 'boolean'),<br />
+ array(12345, 'int')<br />
+ );
+<br />
+$this->xmlrpc->request($request);</code>
+
+The <a href="#datatypes">Data Types</a> section below has a full list of data types.
+
+
+
+<h2>Creating an XML-RPC Server</h2>
+
+<p>An XML-RPC Server acts as a traffic cop of sorts, waiting for incoming requests and redirecting them to the
+appropriate functions for processing.</p>
+
+<p>To create your own XML-RPC server involves initializing the XML-RPC Server class in your controller where you expect the incoming
+request to appear, then setting up an array with mapping instructions so that incoming requests can be sent to the appropriate
+class and method for processing.</p>
+
+<p>Here is an example to illustrate:</p>
+
+<code>
+$this->load->library('xmlrpc');<br />
+$this->load->library('xmlrpcs');<br />
+<br />
+$config['functions']['<var>new_post</var>'] = array('function' => '<dfn>My_blog.new_entry</dfn>');<br />
+$config['functions']['<var>update_post</var>'] = array('function' => '<dfn>My_blog.update_entry</dfn>');<br />
+<br />
+$this->xmlrpcs->initialize($config);<br />
+$this->xmlrpcs->serve();</code>
+
+<p>The above example contains an array specifying two method requests that the Server allows.
+The allowed methods are on the left side of the array. When either of those are received, they will be mapped to the class and method on the right.</p>
+
+<p>In other words, if an XML-RPC Client sends a request for the <var>new_post</var> method, your
+server will load the <dfn>My_blog</dfn> class and call the <dfn>new_entry</dfn> function.
+If the request is for the <var>update_post</var> method, your
+server will load the <dfn>My_blog</dfn> class and call the <dfn>update_entry</dfn> function.</p>
+
+<p>The function names in the above example are arbitrary. You'll decide what they should be called on your server,
+or if you are using standardized APIs, like the Blogger or MetaWeblog API, you'll use their function names.</p>
+
+
+<h2>Processing Server Requests</h2>
+
+<p>When the XML-RPC Server receives a request and loads the class/method for processing, it will pass
+an object to that method containing the data sent by the client.</p>
+
+<p>Using the above example, if the <var>new_post</var> method is requested, the server will expect a class
+to exist with this prototype:</p>
+
+<code>class <kbd>My_blog</kbd> extends Controller {<br />
+<br />
+ function <kbd>new_post</kbd>(<var>$request</var>)<br />
+ {<br />
+ <br />
+ }<br />
+}
+</code>
+
+<p>The <var>$request</var> variable is an object compiled by the Server, which contains the data sent by the XML-RPC Client.
+Using this object you will have access to the <em>request parameters</em> enabling you to process the request. When
+you are done you will send a <dfn>Response</dfn> back to the Client.</p>
+
+<p>Below is a real-world example, using the Blogger API. One of the methods in the Blogger API is <dfn>getUserInfo()</dfn>.
+Using this method, an XML-RPC Client can send the Server a username and password, in return the Server sends
+back information about that particular user (nickname, user ID, email address, etc.). Here is how the processing
+function might look:</p>
+
+
+<code>class <kbd>My_blog</kbd> extends Controller {<br />
+<br />
+ function <kbd>getUserInfo</kbd>(<var>$request</var>)<br />
+ {<br />
+
+ $username = 'smitty';<br />
+ $password = 'secretsmittypass';<br /><br />
+
+ $this->load->library('xmlrpc');<br />
+ <br />
+ $parameters = $request->output_parameters();<br />
+ <br />
+ if ($parameters['1'] != $username AND $parameters['2'] != $password)<br />
+ {<br />
+ return $this->xmlrpc->send_error_message('100', 'Invalid Access');<br />
+ }<br />
+ <br />
+ $response = array(array('nickname' => array('Smitty','string'),<br />
+ 'userid' => array('99','string'),<br />
+ 'url' => array('http://yoursite.com','string'),<br />
+ 'email' => array('jsmith@yoursite.com','string'),<br />
+ 'lastname' => array('Smith','string'),<br />
+ 'firstname' => array('John','string')<br />
+ ),<br />
+ 'struct');<br />
+<br />
+ return $this->xmlrpc->send_response($response);<br />
+ }<br />
+}
+</code>
+
+<h3>Notes:</h3>
+<p>The <dfn>output_parameters()</dfn> function retrieves an indexed array corresponding to the request parameters sent by the client.
+In the above example, the output parameters will be the username and password.</p>
+
+<p>If the username and password sent by the client were not valid, and error message is returned using <dfn>send_error_message()</dfn>.</p>
+
+<p>If the operation was successful, the client will be sent back a response array containing the user's info.</p>
+

+<h3>The Server</h3>
+
+<p>Using a text editor, create a controller called <dfn>xmlrpc_server.php</dfn>.
+In it, place this code and save it to your <samp>applications/controllers/</samp> folder:</p>
+
+<textarea class="textarea" style="width:100%" cols="50" rows="30"><?php
+
+class Xmlrpc_server extends Controller {
+
+ function index()
+ {
+ $this->load->library('xmlrpc');
+ $this->load->library('xmlrpcs');
+
+ $config['functions']['Greetings'] = array('function' => 'Xmlrpc_server.process');
+
+ $this->xmlrpcs->initialize($config);
+ $this->xmlrpcs->serve();
+ }
+
+
+ function process($request)
+ {
+ $parameters = $request->output_parameters();
+
+ $response = array(
+ array(
+ 'you_said' => $parameters['0'],
+ 'i_respond' => 'Not bad at all.'),
+ 'struct');
+
+ return $this->xmlrpc->send_response($response);
+ }
+}
+?></textarea>
+
+<h3>Try it!</h3>
+
+<p>Now visit the your site using a URL similar to this:</p>
+<code>www.your-site.com/index.php/<var>xmlrpc_client</var>/</code>
+
+<p>You should now see the message you sent to the server, and its response back to you.</p>
+
+<p>The client you created sends a message ("How's is going?") to the server, along with a reqest for the "Greetings" method.
+The Server receives the request and maps it to the "process" function, where a response is sent back.</p>
+
+

+<h1>XML-RPC Function Reference</h1>
+
+<h2>$this->xmlrpc->server()</h2>
+<p>Sets the URL and port number of the server to which a request is to be sent:</p>
+<code>$this->xmlrpc->server('http://www.sometimes.com/pings.php', 80);</code>
+
+<h2>$this->xmlrpc->timeout()</h2>
+<p>Set a time out period (in seconds) after which the request will be canceled:</p>
+<code>$this->xmlrpc->timeout(6);</code>
+
+<h2>$this->xmlrpc->method()</h2>
+<p>Sets the method that will be requested from the XML-RPC server:</p>
+<code>$this->xmlrpc->method('<var>method</var>');</code>
+
+<p>Where <var>method</var> is the name of the method.</p>
+
+<h2>$this->xmlrpc->request()</h2>
+<p>Takes an array of data and builds request to be sent to XML-RPC server:</p>
+<code>$request = array(array('My Photoblog', 'string'), 'http://www.yoursite.com/photoblog/');<br />
+$this->xmlrpc->request($request);</code>
+
+<h2>$this->xmlrpc->send_request()</h2>
+<p>The request sending function. Returns boolean TRUE or FALSE based on success for failure, enabling it to be used conditionally.</p>
+
+<h2>$this->xmlrpc->set_debug(TRUE);</h2>
+<p>Enables debugging, which will display a variety of information and error data helpful during development.</p>
+
+
+<h2>$this->xmlrpc->display_error()</h2>
+<p>Returns an error message as a string if your request failed for some reason.</p>
+<code>echo $this->xmlrpc->display_error();</code>
+
+<h2>$this->xmlrpc->display_response()</h2>
+<p>Returns the response from the remote server once request is received. The response will typically be an associative array.</p>
+<code>$this->xmlrpc->display_response();</code>
+
+<h2>$this->xmlrpc->send_error_message()</h2>
+<p>This function lets you send an error message from your server to the client. First parameter is the error number while the second parameter
+is the error message.</p>
+<code>return $this->xmlrpc->send_error_message('123', 'Requested data not available');</code>
+
+<h2>$this->xmlrpc->send_response()</h2>
+<p>Lets you send the response from your server to the client. An array of valid data values must be sent with this method.</p>
+<code>$response = array(<br />
+ array(<br />
+ 'flerror' => array(FALSE, 'boolean'),<br />
+ 'message' => "Thanks for the ping!")<br />
+ )<br />
+ 'struct');<br />
+return $this->xmlrpc->send_response($response);</code>
+
+
+<a name="datatypes"></a>
+<h2>Data Types</h2>
+
+<p>According to the <a href="http://www.xmlrpc.com/spec">XML-RPC spec</a> there are seven types
+of values that you can send via XML-RPC:</p>
+
+<ul>
+<li><em>int</em> or <em>i4</em></li>
+<li><em>boolean</em></li>
+<li><em>string</em></li>
+<li><em>double</em></li>
+<li><em>dateTime.iso8601</em></li>
+<li><em>base64</em></li>
+<li><em>struct</em> (contains array of values)</li>
+<li><em>array</em> (contains array of values)</li>
