CodeIgniter Form Validation Not Working
Solution 1
I have FINALLY found the answer! My server wasn't configured correctly, I didn't have mod_rewrite enabled so none of the requests were working properly or something.
Ubuntu users, fire this off on the command line to enable it: sudo a2enmod rewrite
Then restart Apache.
I am using the following .htaccess:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
#Removes access to the system folder by users.
#Additionally this will allow you to create a System.php controller,
#previously this would not have been possible.
#'system' can be replaced if you have renamed your system folder.
RewriteCond %{REQUEST_URI} ^system.*
RewriteRule ^(.*)$ /index.php?/$1 [L]
#When your application folder isn't in the system folder
#This snippet prevents user access to the application folder
#Rename 'application' to your applications folder name.
RewriteCond %{REQUEST_URI} ^application.*
RewriteRule ^(.*)$ /index.php?/$1 [L]
#Checks to see if the user is attempting to access a valid file,
#such as an image or css document, if this isn't true it sends the
#request to index.php
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /index.php?/$1 [L]
</IfModule>
<IfModule !mod_rewrite.c>
# If we don't have mod_rewrite installed, all 404's
# can be sent to index.php, and everything works as normal.
ErrorDocument 404 /index.php
</IfModule>

You didn't give the controller name in the form_open
function, it should be
<?php echo form_open('registerController/register'); ?>

Can't seem to get form validation working on code igniter, unsure what's wrong!
Here's my controller class:
class registerController extends MY_Controller { // --- Methods ----------------- function __construct() { parent::__construct(); $this->firephp->log('REGISTER PAGE CONTROLLER ACTIVE'); //Load user model $this->load->model('usersModel'); //load form validation $this->load->helper('form'); $this->load->library('form_validation'); } //------------------------------ public function register() { $this->form_validation->set_rules('registerForenameFieldName', 'Fist Name', 'required'); //This is executed when the form is submitted if ($this->form_validation->run() == FALSE) { $this->firephp->log('Registration form validation failed'); //Load in the views $this->load->view('global/head.php'); $this->load->view('global/top.php'); $this->load->view('register/register.php'); $this->load->view('global/footer.php'); } else { $this->firephp->log('Registration form validation succeeded'); //Model method here //Load in the views $this->load->view('global/head.php'); $this->load->view('global/top.php'); $this->load->view('home.php'); $this->load->view('global/footer.php'); } } }
and my form:
<?php echo form_open('register'); ?> <div id="registerErrors"><?php echo validation_errors(); ?></div> <table id="registerTable"> <tr> <td class="regLeftCell"><p>First Name</p></td> <td class="regRightCell"> <input id="registerForenameField" class="textField registerField" name="registerForenameFieldName" type="text" placeholder="Forename" value="<?php echo set_value('registerForenameFieldName'); ?>"></input> </td> </tr> <tr> <td class="regLeftCell"><p>Last Name</p></td> <td class="regRightCell"> <input id="registerSurnameField" class="textField registerField" name="registerSurnameFieldName" type="text" placeholder="Surname" value="<?php echo set_value('registerSurnameFieldName'); ?>"></input> </td> </tr> <tr> <td class="regLeftCell"><p>Email Address</p></td> <td class="regRightCell"> <input id="registerEmailField" class="textField registerField" name="registerEmailFieldName" type="text" placeholder="Email Address"></input> </td> </tr> <tr> <td class="regLeftCell"><p>Choose Password</p></td> <td class="regRightCell"> <input id="registerPasswordField" class="textField registerField" name="registerPasswordFieldName" type="text" placeholder="Password"></input> </td> </tr> <tr> <td class="regLeftCell"><p>Confirm Password</p></td> <td class="regRightCell"> <input id="registerConfirmPasswordField" class="textField registerField" name="registerConfirmPasswordFieldName" type="text" placeholder="Confirm Password"></input> </td> </tr> <tr> <td class="regLeftCell"><p>Address Line 1</p></td> <td class="regRightCell"> <input id="registerAddress1Field" class="textField registerField" name="registerAddress1FieldName" type="text" placeholder="Address Line 1"></input> </td> </tr> <tr> <td class="regLeftCell"><p>Address Line 2</p></td> <td class="regRightCell"> <input id="registerAddress2Field" class="textField registerField" name="registerAddress2FieldName" type="text" placeholder="Address Line 2"></input> </td> </tr> <tr> <td class="regLeftCell"><p>Address Line 3</p></td> <td class="regRightCell"> <input id="registerAddress3Field" class="textField registerField" name="registerAddress3FieldName" type="text" placeholder="Address Line 3"></input> </td> </tr> <tr> <td class="regLeftCell"><p>Post Code</p></td> <td class="regRightCell"> <input id="registerAddressPostCodeField" class="textField registerField" name="registerPostCodeFieldName" type="text" placeholder="Post Code"></input> </td> </tr> <tr> <td class="regLeftCell"><p>Country</p></td> <td class="regRightCell"> <input id="registerAddressCountryField" class="textField registerField" name="registerSurnameFieldName" type="text" placeholder="Country"></input> </td> </tr> </table> <div id="registerButton"> <input class="button registerSubmitButton" type="submit" value="Register"/> </div> </form>
The routing is set up like this:
$route['register'] = 'registerController/register';
What's wrong? It just fails every time without displaying an error.
It just reloads the same page with no validation errors. The $this->form_validation->run() evaluates at FALSE every time because I have logged it in FirePHP, a Firebug extension.
EDIT:
It may also be worth mentioning that I get a 404 error in the console despite it loading the page:
