Loading a Preview before sending a Newsletter

[eluser]AlphaGirl[/eluser]
Found a solution, should be quite safe and clean code, isn't it?

Code:

function newsletter_check()
    {
      if($this->input->post('send') ==! FALSE):  
                switch($this->input->post('send')) {
                    case 'send':
                         // send newsletter email
                        break;
                    case 'preview':
                          $data['title'] = $this->input->post('title');
                          $data['message'] =$this->input->post('message');
                          $this->load->view('admin/preview_view', $data);
                        break;
                }
      else:
          die('Something is wrong!');
      endif;  
        
        
    }
