I have a problem, I want to make a message in view page that "no data found" in codeigniter:

this is in my controller:

```html
 function search_keyword()
 {
      $this->output->set_header('Expires: Sat, 26 Jul 1997 05:00:00 GMT');
      $this->output->set_header('Cache-Control: no-cache, no-store, must-revalidate, max-age=0');
      $this->output->set_header('Cache-Control: post-check=0, pre-check=0', FALSE);
      $this->output->set_header('Pragma: no-cache');
      $session_data = $this->session->userdata('logged_in');

      $data['Username'] = $session_data['Username'];
      $keyword    =   $this->input->post('keyword');
      $data['results']    =   $this->model_adminlogin->search($keyword);

      $this->load->view('result_view',$data);
 }

```
