 <ul>
 	<li>Libraries
 		<ul>
+			<li>Added a new <a href="libraries/form_validation.html">Form Validation Class</a>.  It simplifies setting rules and field names, supports arrays as field names, allows groups of validation rules to be saved in a config file, and adds some helper functions for use in view files.  <strong>Please note that the old Validation class is now deprecated</strong>. We will leave it in the library folder for some time so that existing applications that use it will not break, but you are encouraged to migrate to the new version.</li>
 			<li>Updated the <a href="libraries/sessions.html">Sessions class</a> so that any custom data being saved gets stored to a database rather than the session cookie (assuming you are using a database to store session data), permitting much more data to be saved.</li>
 			<li>Added the ability to store libraries in subdirectories within either the main "libraries" or the local application "libraries" folder. Please see the <a href="libraries/loader.html">Loader class</a> for more info. </li>
 			<li>Added the ability to assign library objects to your own variable names when you use <kbd>this->load->library()</kbd>. Please see the <a href="libraries/loader.html">Loader class</a> for more info. </li>			
 			<li>Changed the output of the profiler to use style attribute rather then clear, and added the id "codeigniter_profiler" to the container div</li>
-			<li>Added <kbd>is_natural()</kbd> and <kbd>is_natural_no_zero()</kbd> to the <a href="libraries/validation.html">Validation class</a>.</li>
 		</ul>
 	</li>
 	<li>Helpers
 		<ul>
+			<li>Added several new "setting" functions to the <a href="helpers/form_helper.html">Form helper</a> that allow POST data to be retrieved and set into forms.  These are intended to be used on their own, or with the new <a href="libraries/form_validation.html">Form Validation Class</a>.</li>
 			<li>Added current_url() and uri_segments() to  <a href="helpers/url_helper.html">URL helper</a>.</li>
 			<li>Improved accuracy of calculations in <a href="helpers/number_helper.html">Number helper</a>.</li>
 			<li>Removed added newlines ("\n") from most form and html helper functions.</li>

+The second (optional) parameter allows you to set a default value for the form. Example:</p>
+
+<code>&lt;input type="text" name="quantity" value="<dfn>&lt;?php echo set_value('quantity', '0'); ?></dfn>" size="50" /></code>

+
+<h1>Upgrading from 1.6.3 to 1.7.0 - In Development!</h1>
+
+<p>Before performing an update you should take your site offline by replacing the index.php file with a static one.</p>
+
+
+
+<h2>Step 1: Update your CodeIgniter files</h2>
+
+<p>Replace these files and directories in your "system" folder with the new versions:</p>
+
+<ul>
+
+<li><dfn>system/codeigniter</dfn></li>
+<li><dfn>system/database</dfn></li>
+<li><dfn>system/helpers</dfn></li>
+<li><dfn>system/language</dfn></li>
+<li><dfn>system/libraries</dfn></li>
+</ul>
+
+<p class="important"><strong>Note:</strong> If you have any custom developed files in these folders please make copies of them first.</p>
+
+
+<h2>Step 2: Update your Session Table</h2>
+
+<p>If you are using the Session class in your application, AND if you are storing session data to a database, you must add a new column named <dfn>user_data</dfn> to your session table. 
+Here is an example of what this column might look like for MySQL:
+
+<code>user_data text NOT NULL</code>
+
+<p>To add this column you will run a query similar to this:</p>
+
+<code>ALTER TABLE `ci_sessions` ADD `user_data` text NOT NULL</code>
+
+<p>You'll find more information regarding the new Session functionality in the  <a href="../libraries/sessions.html">Session class</a> page.</p>
+
+
+<h2>Step 3: Update your Validation Syntax</h2>
+
+<p>This is an <strong>optional</strong>, but recommended step, for people currently using the Validation class.  CI 1.7 introduces a new  <a href="../libraries/form_validation.html">Form Validation class</a>, which 
+deprecates the old Validation library.  We have left the old one in place so that existing applications that use it will not break, but you are encouraged to
+migrate to the new version as soon as possible.  Please read the user guide carefully as the new library works a little differently, and has several new features.</p>
+
+
+
+<h2>Step 4: Update your user guide</h2>
+<p>Please replace your local copy of the user guide with the new version, including the image files.</p>

+<h1>Overview</h1>
+
+
+<p>Before explaining CodeIgniter's approach to data validation, let's describe the ideal scenario:</p>
+
+<ol>
+<li>A form is displayed.</li>
+<li>You fill it in and submit it.</li>
+<li>If you submitted something invalid, or perhaps missed a required item, the form is redisplayed containing your data 
+along with an error message describing the problem.</li>
+<li>This process continues until you have submitted a valid form.</li>
+</ol>
+
+<p>On the receiving end, the script must:</p>
+
+<ol>
+<li>Check for required data.</li>
+<li>Verify that the data is of the correct type, and meets the correct criteria. For example, if a username is submitted
+it must be validated to contain only permitted characters.  It must be of a minimum length,
+and not exceed a maximum length. The username can't be someone else's existing username, or perhaps even a reserved word. Etc.</li>
+<li>Sanitize the data for security.</li>
+<li>Pre-format the data if needed (Does the data need to be trimmed?  HTML encoded?  Etc.)</li>
+<li>Prep the data for insertion in the database.</li>
+</ol>
+
+
+<p>Although there is nothing terribly complex about the above process, it usually requires a significant
+amount of code, and to display error messages, various control structures are usually placed within the form HTML.
+Form validation, while simple to create, is generally very messy and tedious to implement.</p>
+
+<p>&nbsp;</p>
+
+
+<a name="tutorial"></a>
+<h1>Form Validation Tutorial</h1>
+
+<p>What follows is a "hands on" tutorial for implementing CodeIgniters Form Validation.</p>
+
+
+<p>In order to implement form validation you'll need three things:</p>
+
+<ol>
+<li>A <a href="../general/views.html">View</a> file containing a form.</li>
+<li>A View file containing a "success" message to be displayed upon successful submission.</li>
+<li>A <a href="../general/controllers.html">controller</a> function to receive and process the submitted data.</li>
+</ol>
+
+<p>Let's create those three things, using a member sign-up form as the example.</p>
+
+
+
+<a name="theform"></a>
+
+<h2>The Form</h2>
+
+<p>Using a text editor, create a form called <dfn>myform.php</dfn>.  In it, place this code and save it to your <samp>applications/views/</samp>
+folder:</p>
+
+
+<textarea class="textarea" style="width:100%" cols="50" rows="30">&lt;html>
+&lt;head>
+&lt;title>My Form&lt;/title>
+&lt;/head>
+&lt;body>
+
+&lt;?php echo validation_errors(); ?>
+
+&lt;?php echo form_open('form'); ?>
+
+&lt;h5>Username&lt;/h5>
+&lt;input type="text" name="username" value="" size="50" />
+
+&lt;h5>Password&lt;/h5>
+&lt;input type="text" name="password" value="" size="50" />
+
+&lt;h5>Password Confirm&lt;/h5>
+&lt;input type="text" name="passconf" value="" size="50" />
+
+&lt;h5>Email Address&lt;/h5>
+&lt;input type="text" name="email" value="" size="50" />
+
+&lt;div>&lt;input type="submit" value="Submit" />&lt;/div>
+
+&lt;/form>
+
+&lt;/body>
+&lt;/html>
+</textarea>
+
+
+
+
+<a name="thesuccesspage"></a>
+<h2>The Success Page</h2>
+
+
+<p>Using a text editor, create a form called <dfn>formsuccess.php</dfn>.  In it, place this code and save it to your <samp>applications/views/</samp>
+folder:</p>
+
+
+<textarea class="textarea" style="width:100%" cols="50" rows="14">
+&lt;html>
+&lt;head>
+&lt;title>My Form&lt;/title>
+&lt;/head>
+&lt;body>
+
+&lt;h3>Your form was successfully submitted!&lt;/h3>
+
+&lt;p>&lt;?php echo anchor('form', 'Try it again!'); ?>&lt;/p>
+
+&lt;/body>
+&lt;/html>
+</textarea>
+
+
+
+<a name="thecontroller"></a>
+<h2>The Controller</h2>
+
+<p>Using a text editor, create a controller called <dfn>form.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="21">&lt;?php
+
+class Form extends Controller {
+	
+	function index()
+	{
+		$this->load->helper(array('form', 'url'));
+		
+		$this->load->library('form_validation');
+				
+		if ($this->form_validation->run() == FALSE)
+		{
+			$this->load->view('myform');
+		}
+		else
+		{
+			$this->load->view('formsuccess');
+		}
+	}
+}
+?></textarea>
+
+
+<h2>Try it!</h2>
+
+<p>To try your form, visit your site using a URL similar to this one:</p>
+
+<code>example.com/index.php/<var>form</var>/</code>
+
+<p><dfn>If you submit the form you should simply see the form reload.  That's because you haven't set up any validation
+rules yet.</dfn></p>
+
+<p><strong>Since you haven't told the Form Validation class to validate anything yet, it returns <kbd>FALSE</kbd> (boolean false) by default.  The <samp>run()</samp>
+function only returns <kbd>TRUE</kbd> if it has successfully applied your rules without any of them failing.</strong></p>
+
+
+<h2>Explanation</h2>
+
+<p>You'll notice several things about the above pages:</p>
+
+<p>The <dfn>form</dfn> (myform.php) is a standard web form with a couple exceptions:</p>
+
+<ol>
+<li>It uses a <dfn>form helper</dfn> to create the form opening.
+Technically, this isn't necessary.  You could create the form using standard HTML.  However, the benefit of using the helper
+is that it generates the action URL for you, based on the URL in your config file.  This makes your application more portable in the event your URLs change.</li>
+
+<li>At the top of the form you'll notice the following function call:
+<code>&lt;?php echo validation_errors(); ?&gt;</code>
+
+<p>This function will return any error messages sent back by the validator. If there are no messages it returns an empty string.</p>
+</li>
+</ol>
+
+<p>The <dfn>controller</dfn> (form.php) has one function: <dfn>index()</dfn>. This function initializes the validation class and
+loads the <var>form helper</var> and <var>URL helper</var> used by your view files. It also <samp>runs</samp>
+the validation routine. Based on
+whether the validation was successful it either presents the form or the success page.</p>
+
+
+
+
+<a name="validationrules"></a>
+
+<h2>Setting Validation Rules</h2>
+
+<p>CodeIgniter lets you set as many validation rules as you need for a given field, cascading them in order, and it even lets you prep and pre-process the field data
+at the same time. To set validation rules you will use the <dfn>set_rules()</dfn> function:</p>
+
+<code>$this->form_validation->set_rules();</code>
+
+<p>The above function takes <srong>three</strong> parameters as input:</p>
+
+<ol>
+	<li>The field name - the exact name you've given the form field.</li>
+	<li>A "human" name for this field, which will be inserted into the error message. For example, if your field is named "user" you might give it a human name of "Username".</li>
+	<li>The validation rules for this form field.</li>
+</ol>
+
+
+<p><br />Here is an example. In your <dfn>controller</dfn> (form.php), add this code just below the validation initialization function:</p>
+
+<code>
+$this->form_validation->set_rules('username', 'Username', 'required');<br />
+$this->form_validation->set_rules('password', 'Password', 'required');<br />
+$this->form_validation->set_rules('passconf', 'Password Confirmation', 'required');<br />
+$this->form_validation->set_rules('email', 'Email', 'required');<br />
+</code>
+
+<p>Your controller should now look like this:</p>
+
+<textarea class="textarea" style="width:100%" cols="50" rows="28"><?php
+
+class Form extends Controller {
+	
+	function index()
+	{
+		$this->load->helper(array('form', 'url'));
+		
+		$this->load->library('form_validation');
+			
+		$this->form_validation->set_rules('username', 'Username', 'required');
+		$this->form_validation->set_rules('password', 'Password', 'required');
+		$this->form_validation->set_rules('passconf', 'Password Confirmation', 'required');
+		$this->form_validation->set_rules('email', 'Email', 'required');
+			
+		if ($this->form_validation->run() == FALSE)
+		{
+			$this->load->view('myform');
+		}
+		else
+		{
+			$this->load->view('formsuccess');
+		}
+	}
+}
+?></textarea>
+
+<p><dfn>Now submit the form with the fields blank and you should see the error messages.
+If you submit the form with all the fields populated you'll see your success page.</dfn></p>
+
+<p class="important"><strong>Note:</strong> The form fields are not yet being re-populated with the data when
+there is an error.  We'll get to that shortly.</p>

+<h2>Setting Rules Using an Array</h2>
+
+<p>Before moving on it should be noted that the rule setting function can be passed an array if you prefer to set all your rules in one action.
+If you use this approach you must name your array keys as indicated:</p>
+
+<code>
+$config = array(<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array(<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'field'&nbsp;&nbsp;&nbsp;=> 'username', <br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'label'&nbsp;&nbsp;&nbsp;=> 'Username', <br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'rules'&nbsp;&nbsp;&nbsp;=> 'required'<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;),<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array(<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'field'&nbsp;&nbsp;&nbsp;=> 'password', <br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'label'&nbsp;&nbsp;&nbsp;=> 'Password', <br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'rules'&nbsp;&nbsp;&nbsp;=> 'required'<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;),<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array(<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'field'&nbsp;&nbsp;&nbsp;=> 'passconf', <br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'label'&nbsp;&nbsp;&nbsp;=> 'Password Confirmation', <br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'rules'&nbsp;&nbsp;&nbsp;=> 'required'<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;),&nbsp;&nbsp;&nbsp;<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array(<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'field'&nbsp;&nbsp;&nbsp;=> 'email', <br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'label'&nbsp;&nbsp;&nbsp;=> 'Email', <br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'rules'&nbsp;&nbsp;&nbsp;=> 'required'<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;)<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
+<br />
+$this->form_validation->set_rules($config);
+</code>
+
+
+
+
+
+
+<a name="cascadingrules"></a>
+<h2>Cascading Rules</h2>
+
+<p>CodeIgniter lets you pipe multiple rules together.  Let's try it. Change your rules in the third parameter of rule setting function, like this:</p>
+
+<code>
+$this->form_validation->set_rules('username', 'Username', 'required|min_length[5]|max_length[12]');<br />
+$this->form_validation->set_rules('password', 'Password', 'required|matches[passconf]');<br />
+$this->form_validation->set_rules('passconf', 'Password Confirmation', 'required');<br />
+$this->form_validation->set_rules('email', 'Email', 'required|valid_email');<br />
+</code>
+
+<p>The above code sets the following rules:</p>
+
+<ol>
+<li>The username field be no shorter than 5 characters and no longer than 12.</li>
+<li>The password field must match the password confirmation field.</li>
+<li>The email field must contain a valid email address.</li>
+</ol>
+
+<p>Give it a try! Submit your form without the proper data and you'll see new error messages that correspond to your new rules.
+There are numerous rules available which you can read about in the validation reference.</p>
+
+
+
+<a name="preppingdata"></a>
+<h2>Prepping Data</h2>
+
+<p>In addition to the validation functions like the ones we used above, you can also prep your data in various ways.
+For example, you can set up rules like this:</p>
+
+<code>
+$this->form_validation->set_rules('username', 'Username', '<kbd>trim</kbd>|required|min_length[5]|max_length[12]|<kbd>xss_clean</kbd>');<br />
+$this->form_validation->set_rules('password', 'Password', '<kbd>trim</kbd>|required|matches[passconf]|<kbd>md5</kbd>');<br />
+$this->form_validation->set_rules('passconf', 'Password Confirmation', '<kbd>trim</kbd>|required');<br />
+$this->form_validation->set_rules('email', 'Email', '<kbd>trim</kbd>|required|valid_email');<br />
+</code>
+
+
+<p>In the above example, we are "trimming" the fields, converting the password to MD5, and running the username through
+the "xss_clean" function, which removes malicious data.</p>
+
+<p><strong>Any native PHP function that accepts one parameter can be used as a rule, like <dfn>htmlspecialchars</dfn>,
+<dfn>trim</dfn>,  <dfn>MD5</dfn>, etc.</strong></p>
+
+<p><strong>Note:</strong> You will generally want to use the prepping functions <strong>after</strong>
+the validation rules so if there is an error, the original data will be shown in the form.</p>
+
+
+
+
+<a name="repopulatingform"></a>
+<h2>Re-populating the form</h2>
+
+<p>Thus far we have only been dealing with errors.  It's time to repopulate the form field with the submitted data. CodeIgniter offers several helper functions
+that permit you to do this. The one you will use most commonly is:</p>
+
+<code>set_value('field name')</code>
+
+
+<p>Open your <dfn>myform.php</dfn> view file and update the <strong>value</strong> in each field using the <dfn>set_value()</dfn> function:</p>
+
+<p><strong>Don't forget to include each. field name in the <dfn>set_value()</dfn> functions!</strong></p>
+
+
+<textarea class="textarea" style="width:100%" cols="50" rows="30">
+&lt;html>
+&lt;head>
+&lt;title>My Form&lt;/title>
+&lt;/head>
+&lt;body>
+
+&lt;?php echo validation_errors(); ?>
+
+&lt;?php echo form_open('form'); ?>
+
+&lt;h5>Username&lt;/h5>
+&lt;input type="text" name="username" value="&lt;?php echo set_value('username'); ?>" size="50" />
+
+&lt;h5>Password&lt;/h5>
+&lt;input type="text" name="password" value="&lt;?php echo set_value('password'); ?>" size="50" />
+
+&lt;h5>Password Confirm&lt;/h5>
+&lt;input type="text" name="passconf" value="&lt;?php echo set_value('passconf'); ?>" size="50" />
+
+&lt;h5>Email Address&lt;/h5>
+&lt;input type="text" name="email" value="&lt;?php echo set_value('email'); ?>" size="50" />
+
+&lt;div>&lt;input type="submit" value="Submit" />&lt;/div>
+
+&lt;/form>
+
+&lt;/body>
+&lt;/html>
+</textarea>
+
+
+<p><dfn>Now reload your page and submit the form so that it triggers an error.  Your form fields should now be re-populated</dfn></p>
+
+<p class="important"><strong>Note:</strong> The <a href="#functionreference">Function Reference</a> section below contains functions that
+permit you to re-populate &lt;select> menus, radio buttons, and checkboxes.</p>
+
+
+<p><strong>Important Note:</strong> If you use an array as the name of a form field, you must supply it as an array to the function.  Example:</p>
+
+<code>&lt;input type="text" name="<kbd>colors[]</kbd>" value="&lt;?php echo set_value('<kbd>colors[]</kbd>'); ?>" size="50" /></code>
+
+
+
+
+
+<a name="callbacks"></a>
+<h2>Callbacks: Your own Validation Functions</h2>
+
+<p>The validation system supports callbacks to your own validation functions.  This permits you to extend the validation class
+to meet your needs.  For example, if you need to run a database query to see if the user is choosing a unique username, you can
+create a callback function that does that.  Let's create a example of this.</p>
+
+<p>In your controller, change the "username" rule to this:</p>
+
+<code>$this->form_validation->set_rules('username', 'Username', '<kbd>callback_username_check</kbd>');</code>
+
+
+<p>Then add a new function called <dfn>username_check</dfn> to your controller.  Here's how your controller should now look:</p>
+
+
+<textarea class="textarea" style="width:100%" cols="50" rows="44"><?php
+
+class Form extends Controller {
+	
+	function index()
+	{
+		$this->load->helper(array('form', 'url'));
+		
+		$this->load->library('form_validation');
+			
+		$this->form_validation->set_rules('username', 'Username', 'callback_username_check');
+		$this->form_validation->set_rules('password', 'Password', 'required');
+		$this->form_validation->set_rules('passconf', 'Password Confirmation', 'required');
+		$this->form_validation->set_rules('email', 'Email', 'required');
+					
+		if ($this->form_validation->run() == FALSE)
+		{
+			$this->load->view('myform');
+		}
+		else
+		{
+			$this->load->view('formsuccess');
+		}
+	}
+	
+	function username_check($str)
+	{
+		if ($str == 'test')
+		{
+			$this->form_validation->set_message('username_check', 'The %s field can not be the word "test"');
+			return FALSE;
+		}
+		else
+		{
+			return TRUE;
+		}
+	}
+	
+}
+?></textarea>
+
+<p><dfn>Reload your form and submit it with the word "test" as the username.  You can see that the form field data was passed to your
+callback function for you to process.</dfn></p>
+
+<p><strong>To invoke a callback just put the function name in a rule, with "callback_" as the rule prefix.</strong></p>
+
+<p>You can also process the form data that is passed to your callback and return it.  If your callback returns anything other then a boolean TRUE/FALSE
+it is assumed that the data is your newly processed form data.</p>
+
+
+
+
+<a name="settingerrors"></a>
+<h2>Setting Error Messages</h2>
+
+
+<p>All of the native error messages are located in the following language file:  <dfn>language/english/form_validation_lang.php</dfn></p>
+
+<p>To set your own custom message you can either edit that file, or use the following function:</p>
+
+<code>$this->form_validation->set_message('<var>rule</var>', '<var>Error Message</var>');</code>
+
+<p>Where <var>rule</var> corresponds to the name of a particular rule, and <var>Error Message</var> is the text you would like displayed.</p>
+
+<p>If you include <dfn>%s</dfn> in your error string, it will be replaced with the "human" name you used for your field when you set your rules.</p>
+
+<p>In the "callback" example above, the error message was set by passing the name of the function:</p>
+
+<code>$this->form_validation->set_message('username_check')</code>
+
+<p>You can also override any error message found in the languge file.  For example, to change the message for the "required" rule you will do this:</p>
+
+<code>$this->form_validation->set_message('required', 'Your custom message here');</code>
+
+
+
+<a name="errordelimiters"></a>
+<h2>Changing the Error Delimiters</h2>
+
+<p>By default, the Form Validation class adds a paragraph tag (&lt;p&gt;) around each error message shown. You can either change these delimiters globally or 
+individually.</p>
+
+<ol>
+
+<li><strong>Changing delimiters Globally</strong>
+
+<p>To globally change the error delimiters, in your controller function, just after loading the Form Validation class, add this:</p>
+
+<code>&lt;?php echo $this->form_validation->set_error_delimiters('<kbd>&lt;div class="error"></kbd>', '<kbd>&lt;/div></kbd>');</code>
+
+<p>In this example, we've switched to using div tags.</p>
+
+</li>
+
+<li><strong>Changing delimiters Individually</strong></p>
+
+<p>Each of the two error generating functions shown in this tutorial can be supplied their own delimiters as follows:</p>
+
+<code>&lt;?php echo form_error('field name', '<kbd>&lt;div class="error"></kbd>', '<kbd>&lt;/div></kbd>'); ?></code>
+
+</p>Or:</p>
+
+<code>&lt;?php echo validation_errors('<kbd>&lt;div class="error"></kbd>', '<kbd>&lt;/div></kbd>'); ?></code>
+
+</li>
+</ol>
+
+
+
+
+<a name="individualerrors"></a>
+<h2>Showing Errors Individually</h2>
+
+<p>If you prefer to show an error message next to each form field, rather than as a list, you can use the <dfn>form_error()</dfn> function.</p>
+
+<p>Try it! Change your form so that it looks like this:</p>
+
+<textarea class="textarea" style="width:100%" cols="50" rows="18">
+&lt;h5>Username&lt;/h5>
+&lt;?php echo form_error('username'); ?>
+&lt;input type="text" name="username" value="&lt;?php echo set_value('username'); ?>" size="50" />
+
+&lt;h5>Password&lt;/h5>
+&lt;?php echo form_error('password'); ?>
+&lt;input type="text" name="password" value="&lt;?php echo set_value('password'); ?>" size="50" />
+
+&lt;h5>Password Confirm&lt;/h5>
+&lt;?php echo form_error('passconf'); ?>
+&lt;input type="text" name="passconf" value="&lt;?php echo set_value('passconf'); ?>" size="50" />
+
+&lt;h5>Email Address&lt;/h5>
+&lt;?php echo form_error('email'); ?>
+&lt;input type="text" name="email" value="&lt;?php echo set_value('email'); ?>" size="50" />
+</textarea>
+
+<p>If there are no errors, nothing will be shown.  If there is an error, the message will appear.</p>
+
+<p><strong>Important Note:</strong> If you use an array as the name of a form field, you must supply it as an array to the function.  Example:</p>
+
+<code>&lt;?php echo form_error('<kbd>options[size]</kbd>'); ?><br />
+&lt;input type="text" name="<kbd>options[size]</kbd>" value="&lt;?php echo set_value("<kbd>options[size]</kbd>"); ?>" size="50" />
+</code>

+<h1>Saving Sets of Validation Rules to a Config File</h1>
+
+<p>A nice feature of the Form Validation class is that it permits you to store all your validation rules for your entire application in a config file.  You
+can organize these rules into "groups".  These groups can either be loaded automatically when a matching controller/function is called, or
+you can manually call each set as needed.</p>
+
+<h3>How to save your rules</h3>
+
+<p>To store your validation rules, simply create a file named <kbd>form_validation.php</kbd> in your <dfn>application/config/</dfn> folder.
+In that file you will place an array named <kbd>$config</kbd> with your rules. As shown earlier, the validation array will have this prototype:</p>
+
+<code>
+$config = array(<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array(<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'field'&nbsp;&nbsp;&nbsp;=> 'username', <br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'label'&nbsp;&nbsp;&nbsp;=> 'Username', <br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'rules'&nbsp;&nbsp;&nbsp;=> 'required'<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;),<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array(<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'field'&nbsp;&nbsp;&nbsp;=> 'password', <br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'label'&nbsp;&nbsp;&nbsp;=> 'Password', <br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'rules'&nbsp;&nbsp;&nbsp;=> 'required'<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;),<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array(<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'field'&nbsp;&nbsp;&nbsp;=> 'passconf', <br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'label'&nbsp;&nbsp;&nbsp;=> 'Password Confirmation', <br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'rules'&nbsp;&nbsp;&nbsp;=> 'required'<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;),&nbsp;&nbsp;&nbsp;<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array(<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'field'&nbsp;&nbsp;&nbsp;=> 'email', <br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'label'&nbsp;&nbsp;&nbsp;=> 'Email', <br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'rules'&nbsp;&nbsp;&nbsp;=> 'required'<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;)<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
+</code>
+
+<p><dfn>Your validation rule file will be loaded automatically and used when you call the run() function.</dfn></p>
+
+<p class="important">Please note that you MUST name your array $config.</p>
+
+<h3>Creating Sets of Rules</h3>
+
+<p>In order to organize your rules into "sets" requires that you place them into "sub arrays".  Consider the following example, showing two sets of rules.
+We've arbitrarily called these two rules "signup" and "email".  You can name your rules anything you want:</p>
+
+
+<code>$config = array(<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'<kbd>signup</kbd>' = array(<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array(<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'field' => 'username',<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'label' => 'Username',<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'rules' => 'required'<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;),<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array(<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'field' => 'password',<br />

+
+
+<h3>Calling a Specific Rule Group</h3>
+
+<p>In order to call a specific group you will pass its name to the <kbd>run()</kbd> function.  For example, to call the <kbd>signup</kbd> rule you will do this:</p>
+
+<code>
+if ($this->form_validation->run('<kbd>signup</kbd>') == FALSE)<br />
+{<br />
+&nbsp;&nbsp;&nbsp;$this->load->view('myform');<br />
+}<br />
+else<br />
+{<br />
+&nbsp;&nbsp;&nbsp;$this->load->view('formsuccess');<br />
+}<br />
+</code>
+
+
+
+<h3>Associating a Controller Function with a Rule Group</h3>
+
+<p>An alternate (and more automatic) method of calling a rule group is to name it according to the controller class/function you intend to use it with.  For example, let's say you
+have a controller named <kbd>Member</kbd> and a function named <kbd>signup</kbd>.  Here's what your class might look like:</p>
+
+<code>
+&lt;?php<br /><br />
+class <kbd>Member</kbd> extends Controller {<br />
+<br />
+&nbsp;&nbsp;&nbsp;function <kbd>signup</kbd>()<br />
+&nbsp;&nbsp;&nbsp;{&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this->load->library('form_validation');<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if ($this->form_validation->run() == FALSE)<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;{<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this->load->view('myform');<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;}<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;else<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;{<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this->load->view('formsuccess');<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;}<br />
+&nbsp;&nbsp;&nbsp;}<br />
+}<br />
+?></code>
+
+<p>In your validation config file, you will name your rule group <kbd>member/signup</kbd>:
+
+
+<code>$config = array(<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'<kbd>member/signup</kbd>' = array(<br />

+<p>Permits you to set validation rules, as described in the tutorial sections above:</p>
+
+<ul>
+<li><a href="#validationrules">Setting Validation Rules</a></li>
+<li><a href="#savingtoconfig">Saving Groups of Validation Rules to a Config File</a></li>
+</ul>
+
+
+<h2>$this->form_validation->run();</h2>
+
+<p>Runs the validation routines.  Returns boolean TRUE on success and FALSE on failure. You can optionally pass the name of the validation
+group via the function, as described in: <a href="#savingtoconfig">Saving Groups of Validation Rules to a Config File</a>.</p>
+
+
+<h2>$this->form_validation->set_message();</h2>
+
+<p>Permits you to set custom error messages.  See <a href="#settingerrors">Setting Error Messages</a> above.</p>
+
+
+<p>&nbsp;</p>
+
+<a name="helperreference"></a>
+<h1>Helper Reference</h1>
+
+<p>The following helper functions are available for use in the view files containing your forms.  Note that these are procedural functions, so they
+<strong>do not</strong> require you to prepend them with $this->form_validation.</p>
+
+<h2>form_error()</h2>
+
+<p>Shows an individual error message associated with the field name supplied to the function.  Example:</p>
+
+<code>&lt;?php echo form_error('username'); ?></code>
+
+<p>The error delimiters can be optionally specified.  See the <a href="#errordelimiters">Changing the Error Delimiters</a> section above.</p>
+
+
+
+<h2>validation_errors()</h2>
+<p>Shows all error messages as a string:  Example:</p>
+
+<code>&lt;?php echo validation_errors(); ?></code>
+
+<p>The error delimiters can be optionally specified.  See the <a href="#errordelimiters">Changing the Error Delimiters</a> section above.</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>&lt;input type="text" name="quantity" value="<dfn>&lt;?php echo set_value('quantity', '0'); ?></dfn>" size="50" /></code>
+
+<p>The above form will show "0" when loaded for the firs time.</p>
+
+<h2>set_select()</h2>
+
+<p>If you use a <dfn>&lt;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>
+&lt;select name="myselect"><br />
+&lt;option value="one" <dfn>&lt;?php echo  set_select('myselect', 'one', TRUE); ?></dfn> >One&lt;/option><br />
+&lt;option value="two" <dfn>&lt;?php echo  set_select('myselect', 'two'); ?></dfn> >Two&lt;/option><br />
+&lt;option value="three" <dfn>&lt;?php echo  set_select('myselect', 'three'); ?></dfn> >Three&lt;/option><br />
+&lt;/select>
+</code>
+
+
+<h2>set_checkbox()</h2>
+
+<p>Permits you to display a checkbox in the state it was submitted.  The first parameter
+must contain the name of the checkbox, the second parameter must contain its value, and the third (optional) parameter lets you set an item as the default (use boolean TRUE/FALSE). Example:</p>
+
+<code>&lt;input type="checkbox" name="mycheck" value="1" <dfn>&lt;?php echo set_checkbox('mycheck', '1'); ?></dfn> /><br />
+&lt;input type="checkbox" name="mycheck" value="2" <dfn>&lt;?php echo set_checkbox('mycheck', '2'); ?></dfn> /></code>
+
+
+<h2>set_radio()</h2>
+
+<p>Permits you to display radio buttons in the state they were submitted. This function is identical to the <strong>set_checkbox()</strong> function above.</p>
+
+<code>&lt;input type="radio" name="myradio" value="1" <dfn>&lt;?php echo  set_radio('myradio', '1', TRUE); ?></dfn> /><br />
+&lt;input type="radio" name="myradio" value="2" <dfn>&lt;?php echo  set_radio('myradio', '2'); ?></dfn> /></code>
