  $query = $this->user_model->checkUser();
  
  $username = $this->input->post('username');
  $password = sha1($this->input->post('password'));
  
  $this->form_validation->set_rules('username', 'required|trim|max_length[15]');
  $this->form_validation->set_rules('password', 'required|trim|sha1');
    
  if ($this->form_validation->run() === FALSE) {
  
   $data['title'] = "Customer Login";
   $this->load->view('user/logon', $data);
  }
  else {
   if($query) {
    
    $result = $this->user_model->getCustomer();
     foreach($result as $res) {
         $data = array(
           'username'    => $this->input->post('username'),
           'is_user'     => true,
           'last_login'  => time(),
           'customer_id' => $res['id'],
           'acc_number'  => $res['acc_number']
                );
      }
   }
  }
}

Not sure why....[/quote]
what do you mean stalls?

it doesn't work or it has become slower?
