[eluser]Distortion[/eluser]
Hi.. is it possible to set Validation Rules in Response/My_controller ?
Ex. in my response/Account.php.. just don't mind the other Codes..

Code:

class controller_Account extends CI_Controller {

    function login($form_fields){
  $ajax = CJAX::getInstance();
  $this->load->model('account_model');
        
        $this->form_validation->set_rules('email_address', 'Email Address','valid_email|required|xss_clean');
  $this->form_validation->set_rules('password', 'Password', 'required|min_length[1]|max_length[12]|xss_clean');
  $this->_email_address = $form_fields['email_address'];
  $this->_password = $form_fields['password'];
  
  // if the user Enter wrong information Show Validation Errors
  if($this->form_validation->run() == false) {
   // Write Login Logs Error
   $this->logs->write_login(validation_errors());
   $ajax->error(validation_errors(),5);
  }
  else {
                        // Check if the user Account is Exists
   if($this->account_model->login() == true) {
    /* if Registered Go Here.. */
    $this->account_model->set_login_session(); // set Session
                        // Write login logs to ok
    $this->logs->write_login('ok');
                        
          // Redirect User to the page He Viewd
    redirect($this->input->post('return_url'));
   }
   else {
    /* Incorrect Credentials */
                       $ajax->warning('Incorrect Email Address or Password',5);
   }
  }
    }
    
    
}

in my View/Account/login.php

Code:

<?php  if ( ! defined('BASEPATH')) exit('No direct script access allowed'); ?>
<?php

$ajax = CJAX::getInstance();
$ajax->Exec("login",$ajax->form("ajax.php?controller=account&function=login","frmLogin"));

?>
<?php $return_lang = $this->uri->segment(3) ?>
<?php if(!empty($return_lang)): ?>
<h4 id="required">&lt;?php echo $this->lang->line($return_lang) ?&gt;</h4>
&lt;? endif; ?&gt;
<a id='anchor1' href='#'>Anchor 1</a>
<div id="loginContainer">
&lt;form id="frmLogin" method="post" action=""&gt;
&lt;?php
     // Return URL
     echo form_hidden('return_url', $this->uri->uri_string());
?&gt;
<table class="form">
<tr>
    <td id="form_lbl">&lt;?php echo $this->lang->line('lbl_email_address') ?&gt;
    &lt;input type="text" id="a[email_address]" name="a[email_address]"  size="30" value="&lt;?php echo set_value('email_address'); ?&gt;" /&gt;
    </td>
</tr>
<tr>
    <td id="form_lbl">&lt;?php echo $this->lang->line('lbl_password') ?&gt;
    &lt;input  type="password" id="a[password]" name="a[password]" size="30" value="&lt;?php echo set_value('password'); ?&gt;" /&gt;
    </td>
</tr>
</table>
&lt;input type="submit" id="login" name="submit" class="Frmbtn" value="&lt;?php echo $this-&gt;lang-&gt;line('btn_login') ?&gt;" /&gt;
</div>
