-<h1>Form Validation</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 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>
-
-<dfn>CodeIgniter provides a comprehensive validation framework that truly minimizes the amount of code you'll write.
-It also removes all control structures from your form HTML, permitting it to be clean and free of code.</dfn>
-
-<h2>Overview</h2>
-
-<p>In order to implement CodeIgniter's form validation you'll need three things:</p>
-
-<ol>
-<li>A <a href="../general/views.html">View</a> file containing the 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>
-
-<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 $this->validation->error_string; ?>
-
-&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>
-
-
-<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>
-
-
-<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'));
-		
-		$this->load->library('validation');
-				
-		if ($this->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><strong>If you submit the form you should simply see the form reload.  That's because you haven't set up any validation
-rules yet, which we'll get to in a moment.</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
-and flexible in the event your URLs change.</li>
-
-<li>At the top of the form you'll notice the following variable:
-<code>&lt;?php echo $this->validation->error_string; ?&gt;</code>
-
-<p>This variable will display any error messages sent back by the validator. If there are no messages it returns nothing.</p>
-</li>
-</ol>
-
-<p>The <dfn>controller</dfn> (form.php) has one function: <dfn>index()</dfn>. This function initializes the validation class and
-loads the <var>form helper</var> and <var>URL helper</var> used by your view files. It also <samp>runs</samp>
-the validation routine. Based on
-whether the validation was successful it either presents the form or the success page.</p>
-
-<p><strong>Since you haven't told the validation class to validate anything yet, it returns "false" (boolean false) by default.  The <samp>run()</samp>
-function only returns "true" if it has successfully applied your rules without any of them failing.</strong></p>
-
-
-<h2>Setting Validation Rules</h2>
-
-<p>CodeIgniter lets you set as many validation rules as you need for a given field, cascading them in order, and it even lets you prep and pre-process the field data
-at the same time. Let's see it in action, we'll explain it afterwards.</p>
-
-<p>In your <dfn>controller</dfn> (form.php), add this code just below the validation initialization function:</p>
-
-<code>$rules['username']	= "required";<br />
-$rules['password']	= "required";<br />
-$rules['passconf']	= "required";<br />
-$rules['email']		= "required";<br />
-<br />
-$this->validation->set_rules($rules);</code>
-
-<p>Your controller should now look like this:</p>
-
-<textarea class="textarea" style="width:100%" cols="50" rows="28">&lt;?php
-
-class Form extends Controller {
-	
-	function index()
-	{
-		$this->load->helper(array('form', 'url'));
-		
-		$this->load->library('validation');
-			
-		$rules['username']	= "required";
-		$rules['password']	= "required";
-		$rules['passconf']	= "required";
-		$rules['email']		= "required";
-		
-		$this->validation->set_rules($rules);
-			
-		if ($this->validation->run() == FALSE)
-		{
-			$this->load->view('myform');
-		}
-		else
-		{
-			$this->load->view('formsuccess');
-		}
-	}
-}
-?></textarea>
-
-<p><dfn>Now submit the form with the fields blank and you should see the error message.
-If you submit the form with all the fields populated you'll see your success page.</dfn></p>
-
-<p class="important"><strong>Note:</strong> The form fields are not yet being re-populated with the data when
-there is an error.  We'll get to that shortly, once we're through explaining the validation rules.</p>
-
-
-<h2>Changing the Error Delimiters</h2>
-
-<p>By default, the system adds a paragraph tag (&lt;p&gt;) around each error message shown. You can easily change these delimiters with
-this code, placed in your controller:</p>
-
-<code>$this->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>
-
-<h2>Cascading Rules</h2>
-
-<p>CodeIgniter lets you pipe multiple rules together.  Let's try it. Change your rules array like this:</p>
-
-
-<code>$rules['username']	= "required|min_length[5]|max_length[12]";<br />
-$rules['password']	= "required|matches[passconf]";<br />
-$rules['passconf']	= "required";<br />
-$rules['email']		= "required|valid_email";</code>
-
-<p>The above code requires that:</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!</p>
-
-<p class="important"><strong>Note:</strong> There are numerous rules available which you can read about in the validation reference.</p>
-
-
-<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>$rules['username']	= "<kbd>trim</kbd>|required|min_length[5]|max_length[12]|<kbd>xss_clean</kbd>";<br />
-$rules['password']	= "<kbd>trim</kbd>|required|matches[passconf]|<kbd>md5</kbd>";<br />
-$rules['passconf']	= "<kbd>trim</kbd>|required";<br />
-$rules['email']		= "<kbd>trim</kbd>|required|valid_email";</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 class="important"><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>
-
-<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 simple example.</p>
-
-<p>In your controller, change the "username" rule to this:</p>
-
-<code>$rules['username'] = "callback_username_check"; </code>
-
-<p>Then add a new function called <dfn>username_check</dfn> to your controller.  Here's how your controller should look:</p>
-
-
-<textarea class="textarea" style="width:100%" cols="50" rows="44">&lt;?php
-
-class Form extends Controller {
-	
-	function index()
-	{
-		$this->load->helper(array('form', 'url'));
-		
-		$this->load->library('validation');
-			
-		$rules['username']	= "callback_username_check";
-		$rules['password']	= "required";
-		$rules['passconf']	= "required";
-		$rules['email']		= "required";
-		
-		$this->validation->set_rules($rules);
-			
-		if ($this->validation->run() == FALSE)
-		{
-			$this->load->view('myform');
-		}
-		else
-		{
-			$this->load->view('formsuccess');
-		}
-	}
-	
-	function username_check($str)
-	{
-		if ($str == 'test')
-		{
-			$this->validation->set_message('username_check', 'The %s field can not be the word "test"');
-			return FALSE;
-		}
-		else
-		{
-			return TRUE;
-		}
-	}
-	
-}
-?></textarea>
-
-<p>Reload your form and submit it with the word "test" as the username.  You can see that the form field data was passed to your
-callback function for you to process.</p>
-
-<p><strong>To invoke a callback just put the function name in a rule, with "callback_" as the rule prefix.</strong></p>
-
-<p>The error message was set using the <dfn>$this->validation->set_message</dfn> function.
-Just remember that the message key (the first parameter) must match your function name.</p>
-
-<p class="important"><strong>Note:</strong> You can apply your own custom error messages to any rule, just by setting the
-message similarly. For example, to change the message for the "required" rule you will do this:</p>
-
-<code>$this->validation->set_message('required', 'Your custom message here');</code>
-
-<h2>Re-populating the form</h2>
-
-<p>Thus far we have only been dealing with errors.  It's time to repopulate the form field with the submitted data.
-This is done similarly to your rules.  Add the following code to your controller, just below your rules:</p>
-
-<code>$fields['username'] = 'Username';<br />
-$fields['password'] = 'Password';<br />
-$fields['passconf'] = 'Password Confirmation';<br />
-$fields['email'] = 'Email Address';<br />
-<br />
-$this->validation->set_fields($fields);</code>
-
-<p>The array keys are the actual names of the form fields, the value represents the full name that you want shown in the
-error message.</p>
-
-<p>The index function of your controller should now look like this:</p>
-
-
-<textarea class="textarea" style="width:100%" cols="50" rows="30">function index()
-{
-	$this->load->helper(array('form', 'url'));
-	
-	$this->load->library('validation');
-		
-	$rules['username']	= "required";
-	$rules['password']	= "required";
-	$rules['passconf']	= "required";
-	$rules['email']		= "required";
-	
-	$this->validation->set_rules($rules);
-	
-	$fields['username']	= 'Username';
-	$fields['password']	= 'Password';
-	$fields['passconf']	= 'Password Confirmation';
-	$fields['email']	= 'Email Address';
-
-	$this->validation->set_fields($fields);
-		
-	if ($this->validation->run() == FALSE)
-	{
-		$this->load->view('myform');
-	}
-	else
-	{
-		$this->load->view('formsuccess');
-	}
-}</textarea>
-
-
-<p>Now open your <dfn>myform.php</dfn> view file and update the value in each field so that it has an attribute corresponding to its name:</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 $this->validation->error_string; ?>
-
-&lt;?php echo form_open('form'); ?>
-
-&lt;h5>Username&lt;/h5>
-&lt;input type="text" name="username" value="&lt;?php echo $this->validation->username;?>" size="50" />
-
-&lt;h5>Password&lt;/h5>
-&lt;input type="text" name="password" value="&lt;?php echo $this->validation->password;?>" size="50" />
-
-&lt;h5>Password Confirm&lt;/h5>
-&lt;input type="text" name="passconf" value="&lt;?php echo $this->validation->passconf;?>" size="50" />
-
-&lt;h5>Email Address&lt;/h5>
-&lt;input type="text" name="email" value="&lt;?php echo $this->validation->email;?>" size="50" />
-
-&lt;div>&lt;input type="submit" value="Submit" />&lt;/div>
-
-&lt;/form>
-
-&lt;/body>
-&lt;/html>
-</textarea>
-
-
-<p>Now reload your page and submit the form so that it triggers an error.  Your form fields should be populated
-and the error messages will contain a more relevant field name.</p>
-
-
-
-<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 change your form so that it looks like this:</p>
-
-
-<textarea class="textarea" style="width:100%" cols="50" rows="20">
-&lt;h5>Username&lt;/h5>
-&lt;?php echo $this->validation->username_error; ?>
-&lt;input type="text" name="username" value="&lt;?php echo $this->validation->username;?>" size="50" />
-
-&lt;h5>Password&lt;/h5>
-&lt;?php echo $this->validation->password_error; ?>
-&lt;input type="text" name="password" value="&lt;?php echo $this->validation->password;?>" size="50" />
-
-&lt;h5>Password Confirm&lt;/h5>
-&lt;?php echo $this->validation->passconf_error; ?>
-&lt;input type="text" name="passconf" value="&lt;?php echo $this->validation->passconf;?>" size="50" />
-
-&lt;h5>Email Address&lt;/h5>
-&lt;?php echo $this->validation->email_error; ?>
-&lt;input type="text" name="email" value="&lt;?php echo $this->validation->email;?>" size="50" /></textarea>
-
-<p>If there are no errors, nothing will be shown.  If there is an error, the message will appear, wrapped in the delimiters you
-have set (&lt;p> tags by default).</p>
-
-<p class="important"><strong>Note: </strong>To display errors this way you must remember to set your fields using the <kbd>$this->validation->set_fields</kbd>
-function described earlier. The errors will be turned into variables that have "_error" after your field name.
-For example, your "username" error will be available at:<br /><dfn>$this->validation->username_error</dfn>.</p>
-
-

-
-<h2>Setting Custom Error Messages</h2>
-
-<p>All of the native error messages are located in the following language file:  <dfn>language/english/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->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>

-<h2>Dealing with Select Menus, Radio Buttons, and Checkboxes</h2>
-
-<p>If you use select menus, radio buttons or checkboxes, you will want the state of
-these items to be retained in the event of an error.  The Validation class has three functions that help you do this:</p>
-
-<h2>set_select()</h2>
-
-<p>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. Example:</p>
-
-<code>
-&lt;select name="myselect"><br />
-&lt;option value="one" <dfn>&lt;?php echo  $this->validation->set_select('myselect', 'one'); ?></dfn> >One&lt;/option><br />
-&lt;option value="two" <dfn>&lt;?php echo  $this->validation->set_select('myselect', 'two'); ?></dfn> >Two&lt;/option><br />
-&lt;option value="three" <dfn>&lt;?php echo  $this->validation->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. Example:</p>
-
-<code>&lt;input type="checkbox" name="mycheck" value="1" <dfn>&lt;?php echo  $this->validation->set_checkbox('mycheck', '1'); ?></dfn> /></code>
-
-
-<h2>set_radio()</h2>
-
-<p>Permits you to display radio buttons in the state they were submitted.  The first parameter
-must contain the name of the radio button, the second parameter must contain its value. Example:</p>
-
-<code>&lt;input type="radio" name="myradio" value="1" <dfn>&lt;?php echo  $this->validation->set_radio('myradio', '1'); ?></dfn> /></code>
