Class Verifylogin extends CI_Controller
{
  function __construct()
  {
      parent::__construct();
      $this->load->model('user','',TRUE);
  }

  function index()
  {
      $this->load->library('form_validation');
      $this->form_validation->set_rules('username', 'username', 'trim|required|xss_clean');
      $this->form_validation->set_rules('password', 'password', 'trim|required|xss_clean|callback_check_database');

      if($this->form_validation->run()== FALSE)
      {
        //Field validation failed.  User redirected to login page
        $this->load->view('login_view');
      }
      else
      {
        //Go to private area
        redirect('Home', 'refresh');
      }
  }


  function check_database($password)
  {
      //Field validation succeeded.  Validate against database
      echo  $username = $this->input->post('username');


      //query the database
      echo  $result = $this->user->login($username, $password);

      if($result)
      {
          $sess_array = array();
          foreach($result as $row)
          {
            $sess_array = array(
            'id' => $row->id,
            'username' => $row->username
            );
            $this->session->set_userdata('logged_in', $sess_array);
          }
          return TRUE;
      }
      else
      {
          $this->form_validation->set_message('check_database', 'Invalid username or password');
          return false;
      }
  }
}
