Takes a "human" time as input and returns it as Unix. This function is -useful if you accept "human" formatted dates submitted via a form. Returns FALSE (boolean) if -the date string passed to it is not formatted as indicated above. Example:</p> - -<code>$now = time();<br /> -<br /> -$human = unix_to_human($now);<br /> -<br /> -$unix = human_to_unix($human);</code> - - - - - -<h2>timespan()</h2> - -<p>Formats a unix timestamp so that is appears similar to this:</p> - -<code>1 Year, 10 Months, 2 Weeks, 5 Days, 10 Hours, 16 Minutes</code> - -<p>The first parameter must contain a Unix timestamp. The second parameter must contain a -timestamp that is greater that the first timestamp. If the second parameter empty, the current time will be used. The most common purpose -for this function is to show how much time has elapsed from some point in time in the past to now. Example:</p> - -<code>$post_date = '1079621429';<br /> -$now = time();<br /> -<br /> -echo timespan($post_date, $now);</code> - -<p class="important"><strong>Note:</strong> The text generated by this function is found in the following language file: language/<your_lang>/date_lang.php</p> - - -<h2>days_in_month()</h2> - -<p>Returns the number of days in a given month/year. Takes leap years into account. Example:</p> -<code>echo days_in_month(06, 2005);</code> - -<p>If the second parameter is empty, the current year will be used.</p> -<h2>timezones()</h2> -<p> Takes a timezone reference (for a list of valid timezones, see the "Timezone Reference" below) and returns the number of hours offset from UTC.</p> -<p><code>echo timezones('UM5');</code></p> -<p>This function is useful when used with timezone_menu(). </p> -<h2>timezone_menu()</h2> -<p>Generates a pull-down menu of timezones, like this one:</p> - -<form action="#"> -<select name="timezones"> -<option value='UM12'>(UTC - 12:00) Enitwetok, Kwajalien</option> -<option value='UM11'>(UTC - 11:00) Nome, Midway Island, Samoa</option> -<option value='UM10'>(UTC - 10:00) Hawaii</option> -<option value='UM9'>(UTC - 9:00) Alaska</option> -<option value='UM8'>(UTC - 8:00) Pacific Time</option> -<option value='UM7'>(UTC - 7:00) Mountain Time</option> -<option value='UM6'>(UTC - 6:00) Central Time, Mexico City</option> -<option value='UM5'>(UTC - 5:00) Eastern Time, Bogota, Lima, Quito</option> -<option value='UM4'>(UTC - 4:00) Atlantic Time, Caracas, La Paz</option> -<option value='UM25'>(UTC - 3:30) Newfoundland</option> -<option value='UM3'>(UTC - 3:00) Brazil, Buenos Aires, Georgetown, Falkland Is.</option> -<option value='UM2'>(UTC - 2:00) Mid-Atlantic, Ascention Is., St Helena</option> -<option value='UM1'>(UTC - 1:00) Azores, Cape Verde Islands</option> -<option value='UTC' selected='selected'>(UTC) Casablanca, Dublin, Edinburgh, London, Lisbon, Monrovia</option> -<option value='UP1'>(UTC + 1:00) Berlin, Brussels, Copenhagen, Madrid, Paris, Rome</option> -<option value='UP2'>(UTC + 2:00) Kaliningrad, South Africa, Warsaw</option> -<option value='UP3'>(UTC + 3:00) Baghdad, Riyadh, Moscow, Nairobi</option> -<option value='UP25'>(UTC + 3:30) Tehran</option> -<option value='UP4'>(UTC + 4:00) Adu Dhabi, Baku, Muscat, Tbilisi</option> -<option value='UP35'>(UTC + 4:30) Kabul</option> -<option value='UP5'>(UTC + 5:00) Islamabad, Karachi, Tashkent</option> -<option value='UP45'>(UTC + 5:30) Bombay, Calcutta, Madras, New Delhi</option> -<option value='UP6'>(UTC + 6:00) Almaty, Colomba, Dhaka</option> -<option value='UP7'>(UTC + 7:00) Bangkok, Hanoi, Jakarta</option> -<option value='UP8'>(UTC + 8:00) Beijing, Hong Kong, Perth, Singapore, Taipei</option> -<option value='UP9'>(UTC + 9:00) Osaka, Sapporo, Seoul, Tokyo, Yakutsk</option> -<option value='UP85'>(UTC + 9:30) Adelaide, Darwin</option> -<option value='UP10'>(UTC + 10:00) Melbourne, Papua New Guinea, Sydney, Vladivostok</option> -<option value='UP11'>(UTC + 11:00) Magadan, New Caledonia, Solomon Islands</option> -<option value='UP12'>(UTC + 12:00) Auckland, Wellington, Fiji, Marshall Island</option> -</select> -</form> - -<p>This menu is useful if you run a membership site in which your users are allowed to set their local timezone value.</p> - -<p>The first parameter lets you set the "selected" state of the menu.

The first parameter will contain the name of the field, -the second parameter will contain an associative array of options, and the third parameter will contain the -value or values you wish to be selected. The parameter usage is identical to using <kbd>form_dropdown()</kbd> above, -except of course that the name of the field will need to use POST array syntax, e.g. <samp>foo[]</samp>.</p> - - -<h2>form_fieldset()</h2> - -<p>Lets you generate fieldset/legend fields.</p> -<code>echo form_fieldset('Address Information');<br /> -echo "<p>fieldset content here</p>\n";<br /> -echo form_fieldset_close(); -<br /> -<br /> -// Produces<br /> -<fieldset> -<br /> -<legend>Address Information</legend> -<br /> -<p>form content here</p> -<br /> -</fieldset></code> -<p>Similar to other functions, you can submit an associative array in the second parameter if you prefer to set additional attributes. </p> -<p><code>$attributes = array('id' => 'address_info', 'class' => 'address_info');<br /> - echo form_fieldset('Address Information', $attributes);<br /> -echo "<p>fieldset content here</p>\n";<br /> -echo form_fieldset_close(); <br /> -<br /> -// Produces<br /> -<fieldset id="address_info" class="address_info"> <br /> -<legend>Address Information</legend> <br /> -<p>form content here</p> <br /> -</fieldset></code></p> -<h2>form_fieldset_close()</h2> -<p>Produces a closing </fieldset> tag. The only advantage to using this function is it permits you to pass data to it - which will be added below the tag. For example:</p> -<code>$string = "</div></div>";<br /> -<br /> -echo fieldset_close($string);<br /> -<br /> -// Would produce:<br /> -</fieldset><br /> -</div></div></code> -<h2>form_checkbox()</h2> -<p>Lets you generate a checkbox field. Simple example:</p> -<code>echo form_checkbox('newsletter', 'accept', TRUE);<br /> -<br /> -// Would produce:<br /> -<br /> -<input type="checkbox" name="newsletter" value="accept" checked="checked" /></code> -<p>The third parameter contains a boolean TRUE/FALSE to determine whether the box should be checked or not.</p> -<p>Similar to the other form functions in this helper, you can also pass an array of attributes to the function:</p> - -<code>$data = array(<br /> - 'name' => 'newsletter',<br /> - 'id' => 'newsletter',<br /> - 'value' => 'accept',<br /> - 'checked' => TRUE,<br /> - 'style' => 'margin:10px',<br /> - );<br /> -<br /> -echo form_checkbox($data);<br /> -<br /> -// Would produce:<br /><br /> -<input type="checkbox" name="newsletter" id="newsletter" value="accept" checked="checked" style="margin:10px" /></code> - -<p>As with other functions, if you would like the tag to contain additional data, like JavaScript, you can pass it as a string in the -fourth parameter:</p> - -<code>$js = 'onClick="some_function()"';<br /> -<br /> - echo form_checkbox('newsletter', 'accept', TRUE, $js)</code> - - -<h2>form_radio()</h2> -<p>This function is identical in all respects to the <dfn>form_checkbox()</dfn> function above except that is sets it as a "radio" type.</p> - - -<h2>form_submit()</h2> - -<p>Lets you generate a standard submit button. Simple example:</p> -<code>echo form_submit('mysubmit', 'Submit Post!');<br /> -<br /> -// Would produce:<br /> -<br /> -<input type="submit" name="mysubmit" value="Submit Post!" /></code> -<p>Similar to other functions, you can submit an associative array in the first parameter if you prefer to set your own attributes. - The third parameter lets you add extra data to your form, like JavaScript.</p> -<h2>form_label()</h2> -<p>Lets you generate a <label>. Simple example:</p> -<code>echo form_label('What is your Name', 'username');<br /> -<br /> -// Would produce: -<br /> -<label for="username">What is your Name</label></code> -<p>Similar to other functions, you can submit an associative array in the third parameter if you prefer to set additional attributes. </p> -<p><code>$attributes = array(<br /> - 'class' => 'mycustomclass',<br /> - 'style' => 'color: #000;',<br /> -);<br /> - echo form_label('What is your Name', 'username', $attributes);<br /> - <br /> -// Would produce: <br /> -<label for="username" class="mycustomclass" style="color: #000;">What is your Name</label></code></p> -<h2>form_reset()</h2> - -<p>Lets you generate a standard reset button. Use is identical to <dfn>form_submit()</dfn>.</p> - -<h2>form_button()</h2> - -<p>Lets you generate a standard button element. You can minimally pass the button name and content in the first and second parameter:</p> -<code> -echo form_button('name','content');<br /> -<br /> -// Would produce<br /> -<button name="name" type="button">Content</button> -</code> - -Or you can pass an associative array containing any data you wish your form to contain: -<code> -$data = array(<br /> - 'name' => 'button',<br /> - 'id' => 'button',<br /> - 'value' => 'true',<br /> - 'type' => 'reset',<br /> - 'content' => 'Reset'<br /> -);<br /> -<br /> -echo form_button($data);<br /> -<br /> -// Would produce:<br /> -<button name="button" id="button" value="true" type="reset">Reset</button> -</code> - -If you would like your form to contain some additional data, like JavaScript, you can pass it as a string in the third parameter: -<code> -$js = 'onClick="some_function()"';<br /><br /> -echo form_button('mybutton', 'Click Me', $js); -</code> - - -<h2>form_close()</h2> - -<p>Produces a closing </form> tag. The only advantage to using this function is it permits you to pass data to it -which will be added below the tag. For example:</p> - -<code>$string = "</div></div>";<br /> -<br /> -echo form_close($string);<br /> -<br /> -// Would produce:<br /> -<br /> -</form><br /> -</div></div></code> - - - - - -<h2>form_prep()</h2> - -<p>Allows you to safely use HTML and characters such as quotes within form elements without breaking out of the form. Consider this example:</p> - -<code>$string = 'Here is a string containing <strong>"quoted"</strong> text.';<br /> -<br /> -<input type="text" name="myform" value="<var>$string</var>" /></code> - -<p>Since the above string contains a set of quotes it will cause the form to break. -The form_prep function converts HTML so that it can be used safely:</p> - -<code><input type="text" name="myform" value="<var><?php echo form_prep($string); ?></var>" /></code> - -<p class="important"><strong>Note:</strong> If you use any of the form helper functions listed in this page the form -values will be prepped automatically, so there is no need to call this function. Use it only if you are -creating your own form elements.</p> - - -<h2>set_value()</h2> - -<p>Permits you to set the value of an input form or textarea. You must supply the field name via the first parameter of the function. -The second (optional) parameter allows you to set a default value for the form. Example:</p> - -<code><input type="text" name="quantity" value="<dfn><?php echo set_value('quantity', '0'); ?></dfn>" size="50" /></code> - -<p>The above form will show "0" when loaded for the first time.</p> - -<h2>set_select()</h2> - -<p>If you use a <dfn><select></dfn> menu, this function permits you to display the menu item that was selected. The first parameter -must contain the name of the select menu, the second parameter must contain the value of -each item, and the third (optional) parameter lets you set an item as the default (use boolean TRUE/FALSE).</p> - -<p>Example:</p> - -<code> -<select name="myselect"><br /> -<option value="one" <dfn><?php echo set_select('myselect', 'one', TRUE); ?></dfn> >One</option><br /> -<option value="two" <dfn><?php echo set_select('myselect', 'two'); ?></dfn> >Two</option><br /> -<option value="three" <dfn><?php echo set_select('myselect', 'three'); ?></dfn> >Three</option><br /> -</select> -</code> - - -<h2>set_checkbox()</h2> - -<p>Permits you to display a checkbox in the state it was submitted.

Example:</p> - -<code> -$string = "Here is a nice text string consisting of eleven words.";<br /> -<br /> -$string = character_limiter($string, 20);<br /><br /> - -// Returns: Here is a nice text string… -</code> - -<p>The third parameter is an optional suffix added to the string, if undeclared this helper uses an ellipsis.</p> - - - -<h2>ascii_to_entities()</h2> - -<p>Converts ASCII values to character entities, including high ASCII and MS Word characters that can cause problems when used in a web page, -so that they can be shown consistently regardless of browser settings or stored reliably in a database. -There is some dependence on your server's supported character sets, so it may not be 100% reliable in all cases, but for the most -part it should correctly identify characters outside the normal range (like accented characters). Example:</p> - -<code>$string = ascii_to_entities($string);</code> - - -<h2>entities_to_ascii()</h2> - -<p>This function does the opposite of the previous one; it turns character entities back into ASCII.</p> - -<h2>convert_accented_characters()</h2> - -<p>Transliterates high ASCII characters to low ASCII equivalents, useful when non-English characters need to be used where only standard ASCII characters are safely used, for instance, in URLs.</p> - -<code>$string = convert_accented_characters($string);</code> - -<p>This function uses a companion config file <dfn>application/config/foreign_chars.php</dfn> to define the to and from array for transliteration.</p> - -<h2>word_censor()</h2> - -<p>Enables you to censor words within a text string. The first parameter will contain the original string. The -second will contain an array of words which you disallow. The third (optional) parameter can contain a replacement value -for the words. If not specified they are replaced with pound signs: ####. Example:</p> - -<code> -$disallowed = array('darn', 'shucks', 'golly', 'phooey');<br /> -<br /> -$string = word_censor($string, $disallowed, 'Beep!');</code> - - -<h2>highlight_code()</h2> - -<p>Colorizes a string of code (PHP, HTML, etc.). Example:</p> - -<code>$string = highlight_code($string);</code> - -<p>The function uses PHP's highlight_string() function, so the colors used are the ones specified in your php.ini file.</p> - - -<h2>highlight_phrase()</h2> - -<p>Will highlight a phrase within a text string. The first parameter will contain the original string, the second will -contain the phrase you wish to highlight. The third and fourth parameters will contain the opening/closing HTML tags -you would like the phrase wrapped in. Example:</p> - -<code> -$string = "Here is a nice text string about nothing in particular.";<br /> -<br /> -$string = highlight_phrase($string, "nice text", '<span style="color:#990000">', '</span>'); -</code> - -<p>The above text returns:</p> - -<p>Here is a <span style="color:#990000">nice text</span> string about nothing in particular.</p> - - - -<h2>word_wrap()</h2> - -<p>Wraps text at the specified <strong>character</strong> count while maintaining complete words. Example:</p> - -<code>$string = "Here is a simple string of text that will help us demonstrate this function.";<br /> -<br /> -echo word_wrap($string, 25);<br /> -<br /> -// Would produce:<br /> -<br /> -Here is a simple string<br /> -of text that will help<br /> -us demonstrate this<br /> -function</code> - -<h2>ellipsize()</h2> - -<p>This function will strip tags from a string, split it at a defined maximum length, and insert an ellipsis.</p> -<p>The first parameter is the string to ellipsize, the second is the number of characters in the final string. The third parameter is where in the string the ellipsis should appear from 0 - 1, left to right. For example. a value of 1 will place the ellipsis at the right of the string, .5 in the middle, and 0 at the left.</p> -<p>An optional forth parameter is the kind of ellipsis. By default, <samp>&hellip;</samp> will be inserted.</p> - -<code>$str = 'this_string_is_entirely_too_long_and_might_break_my_design.jpg';<br /> -<br /> -echo ellipsize($str, 32, .5);</code> - -Produces: - -<code>this_string_is_e…ak_my_design.jpg</code> - - -</div> -<!-- END CONTENT --> - - -<div id="footer"> -<p> -Previous Topic: <a href="string_helper.html">String Helper</a> - · -<a href="#top">Top of Page</a> · -<a href="../index.html">User Guide Home</a> · -Next Topic: <a href="typography_helper.html">Typography Helper</a> -</p> -<p><a href="http://codeigniter.com">CodeIgniter</a> · Copyright © 2006 - 2011 · <a href="http://ellislab.com/">EllisLab, Inc.</a></p> -</div> - -</body> -</html>

The attributes can be a simple string or an associative array.</p> - -<p>Here are some examples:</p> - -<code>echo anchor('news/local/123', 'My News', 'title="News title"');</code> - -<p>Would produce: <a href="http://example.com/index.php/news/local/123" title="News title">My News</a></p> - -<code>echo anchor('news/local/123', 'My News', array('title' => 'The best news!'));</code> - -<p>Would produce: <a href="http://example.com/index.php/news/local/123" title="The best news!">My News</a></p> - - -<h2>anchor_popup()</h2> - -<p>Nearly identical to the <dfn>anchor()</dfn> function except that it opens the URL in a new window. - -You can specify JavaScript window attributes in the third parameter to control how the window is opened. If -the third parameter is not set it will simply open a new window with your own browser settings. Here is an example -with attributes:</p> - -<code> - -$atts = array(<br /> - 'width' => '800',<br /> - 'height' => '600',<br /> - 'scrollbars' => 'yes',<br /> - 'status' => 'yes',<br /> - 'resizable' => 'yes',<br /> - 'screenx' => '0',<br /> - 'screeny' => '0'<br /> - );<br /> -<br /> -echo anchor_popup('news/local/123', 'Click Me!', $atts);</code> - -<p>Note: The above attributes are the function defaults so you only need to set the ones that are different from what you need. -If you want the function to use all of its defaults simply pass an empty array in the third parameter:</p> - -<code>echo anchor_popup('news/local/123', 'Click Me!', array());</code> - - -<h2>mailto()</h2> - -<p>Creates a standard HTML email link. Usage example:</p> - -<code>echo mailto('me@my-site.com', 'Click Here to Contact Me');</code> - -<p>As with the <dfn>anchor()</dfn> tab above, you can set attributes using the third parameter.</p> - - -<h2>safe_mailto()</h2> - -<p>Identical to the above function except it writes an obfuscated version of the mailto tag using ordinal numbers -written with JavaScript to help prevent the email address from being harvested by spam bots.</p> - - -<h2>auto_link()</h2> - -<p>Automatically turns URLs and email addresses contained in a string into links. Example:</p> - -<code>$string = auto_link($string);</code> - -<p>The second parameter determines whether URLs and emails are converted or just one or the other. Default behavior is both -if the parameter is not specified. Email links are encoded as safe_mailto() as shown above.</p> - -<p>Converts only URLs:</p> -<code>$string = auto_link($string, 'url');</code> - -<p>Converts only Email addresses:</p> -<code>$string = auto_link($string, 'email');</code> - -<p>The third parameter determines whether links are shown in a new window. The value can be TRUE or FALSE (boolean):</p> -<code>$string = auto_link($string, 'both', TRUE);</code> - - -<h2>url_title()</h2> -<p>Takes a string as input and creates a human-friendly URL string. This is useful if, for example, you have a blog -in which you'd like to use the title of your entries in the URL. Example:</p> - -<code>$title = "What's wrong with CSS?";<br /> -<br /> -$url_title = url_title($title);<br /> -<br /> -// Produces: Whats-wrong-with-CSS -</code> - - -<p>The second parameter determines the word delimiter. By default dashes are used. Options are: <dfn>dash</dfn>, or <dfn>underscore</dfn>:</p> - -<code>$title = "What's wrong with CSS?";<br /> -<br /> -$url_title = url_title($title, 'underscore');<br /> -<br /> -// Produces: Whats_wrong_with_CSS -</code> - -<p>The third parameter determines whether or not lowercase characters are forced. By default they are not. Options are boolean <dfn>TRUE</dfn>/<dfn>FALSE</dfn>:</p> - -<code>$title = "What's wrong with CSS?";<br /> -<br /> -$url_title = url_title($title, 'underscore', TRUE);<br /> -<br /> -// Produces: whats_wrong_with_css -</code> - -<h3>prep_url()</h3> -<p>This function will add <kbd>http://</kbd> in the event that a scheme is missing from a URL. Pass the URL string to the function like this:</p> -<code> -$url = "example.com";<br /><br /> -$url = prep_url($url);</code> - - - - -<h2>redirect()</h2> - -<p>Does a "header redirect" to the URI specified. If you specify the full site URL that link will be build, but for local links simply providing the URI segments -to the controller you want to direct to will create the link. The function will build the URL based on your config file values.</p> - -<p>The optional second parameter allows you to choose between the "location" -method (default) or the "refresh" method. Location is faster, but on Windows servers it can sometimes be a problem. The optional third parameter allows you to send a specific HTTP Response Code - this could be used for example to create 301 redirects for search engine purposes. The default Response Code is 302. The third parameter is <em>only</em> available with 'location' redirects, and not 'refresh'. Examples:</p> - -<code>if ($logged_in == FALSE)<br /> -{<br /> - redirect('/login/form/', 'refresh');<br /> -}<br /> -<br /> -// with 301 redirect<br /> -redirect('/article/13', 'location', 301);</code> - -<p class="important"><strong>Note:</strong> In order for this function to work it must be used before anything is outputted -to the browser since it utilizes server headers.<br /> -<strong>Note:</strong> For very fine grained control over headers, you should use the <a href="../libraries/output.html">Output Library</a>'s set_header() function.</p> - - - - - - -</div> -<!-- END CONTENT --> - - -<div id="footer"> -<p> -Previous Topic: <a href="typography_helper.html">Typography Helper</a> - · -<a href="#top">Top of Page</a> · -<a href="../index.html">User Guide Home</a> · -Next Topic: <a href="xml_helper.html">XML Helper</a> -</p> -<p><a href="http://codeigniter.com">CodeIgniter</a> · Copyright © 2006 - 2011 · <a href="http://ellislab.com/">EllisLab, Inc.</a></p> -</div> - -</body> -</html>
