my_form_validation issue?

[eluser]Matalina[/eluser]
I can't get the extended library to run. I've indicated the exit() that isn't working in the function. A second set of eyes would be helpful.

Controller:

Code:

public function profile() {
    // Is the user logged in?
    if(!$this->ion_auth->logged_in()) {
      $this->session->set_flashdata('warning','<div class="alert-box warning">You must be logged in.</div>');
      redirect('site/index');
    }
    
    // Get users information
    $user = $this->ion_auth->user()->row_array();
    
    if($this->input->post('update')) {
      $this->form_validation->set_rules('email','valid_email|unique_email');
      $this->form_validation->set_rules('password','xss_clean');
      $this->form_validation->set_rules('confirm','xss_clean|match[password]');
      
      $this->form_validation->set_message('unique_email','Email already in use');
      
      if($this->form_validation->run() && ($this->input->post('email') OR $this->input->post('password'))) {
        $id = $this->session->userdata('user_id');
        if($this->input->post('email')) {
          $info['email'] = $this->input->post('email');
        }
        if($this->input->post('password')) {
          $info['password'] = $this->input->post('password');
        }
        $check = $this->ion_auth->update($id,$info);
        if($check) {
          $this->session->set_flashdata('success','<div class="alert-box success">User has been updated.</div>');
          redirect('site/profile');
        }
        else {
          $this->session->set_flashdata('error','<div class="alert-box error">User has not been updated.</div>');
          redirect('site/profile');
        }
      }
    }
    
    // set data & display page
    $data['user'] = $user;
    $data['title'] = 'My Profile';
    $this->template->load('templates/main_template','user/profile',$data);
  }

/application/libraries/MY_Form_validation

Code:

function unique_email($email) {
     echo '<pre>'; print_r($email); echo '<pre/>'; exit(); // <-- not working
     $this->CI->load->model('User_model');
     $this->CI->load->model('Stores_model');
    
     if($this->CI->input->post('user_id')) {
       $user_id = $this->CI->input->post('user_id');
     }
     else if($this->CI->input->post('create')){
       $user_id = 0;
     }
     else {
       $user_id = $this->CI->session->userdata('user_id');
     }

    $user_query = $this->CI->User_model->get(array('id' => $user_id));
    
    if($user->num_rows() > 0) {
      $user = $user_query->row_array();
    }
    else {
      $user = false;
    }
    
    $email_query = $this->CI->User_model->get(array('email' => $email));
    
    if($email_query->num_rows() > 0) {
      if($email_query->row()->id == $user['id']) {
        $this->CI->form_validation->set_message('unique_email','You are already using this email address');
        return FALSE0;
      }
      else {
        $this->CI->form_validation->set_message('unique_email','Someone has this email address already');
        return FALSE;
      }
    }
    
    $store_query = $this->CI->Stores_model->get(array('email' => $email));
    
    if($store_query->num_rows() > 0) {
      $this->CI->form_validation->set_message('unique_email','You may not use a store email address');
        return FALSE;
    }
    
    return TRUE;  
   }

echo and exit in constructor is working so it's not a loading issue.

*edit*

stupid mistake - missing a parameter!

[eluser]CroNiX[/eluser]
When extending a native library, you don't need to do "$this->CI->form_validation->..." within it, just use $this as $this IS the form_validation library (in this case).

[eluser]Matalina[/eluser]
every tutorial I read on the subject was using it, are they incorrect?

[eluser]CroNiX[/eluser]
It's still just php. How is it any different than extending a controller or model?

[eluser]Aken[/eluser]
Those tutorials are probably about creating your own unique library, not extending an existing one.
