Login Form

The set rules are working, but run() don't. Why?

Code:

function login() {
if ($this->input->post('action') == 'login') {
  $this->form_validation->set_rules('username', 'Usuario', 'trim|required|alpha_numeric');
  $this->form_validation->set_rules('password', 'Senha', 'trim|required|alpha_numeric');
      
  if ($this->form_validation->run()) {
   $data = array('username' => $this->input->post('username'),
        'password' => $this->input->post('password'),
   );
  
   if ($this->Usermodel->read('users', $data)) {
    $this->form_validation->set_message('login', 'Login ok.');
   } else {
    $this->form_validation->set_message('login', 'Login not ok.');
   }
  }
  
}
  
$data['page_title'] = "Login";
$data['query'] = $this->Usermodel->get_user();
$this->load->view('header', $data);
$this->load->view('login');
$this->load->view('footer');
}

Code:

function read($table, $data) {
$query = $this->db->get_where($table, $data);

if ($query->num_rows() == 0) {
  return FALSE;
} else {
  return TRUE;
}
}

The function read() is ok because I use it in other places and its fine.
