codeigniter 3.0 custom 404 not found error page

Question

My problem is about custom error pages after upgrading to Codeigniter 3.0.

I used to have a Errors controller which handled 404 error page of the websi

Answer 1

that is working good, but if redirect to an error, for example 404 with function show_404, your controller wont load your view, for a real 404 in the show_404 method, you have to go to the core of codeigniter and touch it.

\system\core\Common.php

this is an example of code:

function show_404(){
  $ci = get_instance();
  $ci->output->set_status_header(404);
  $ci->load->view('errors/error404_view');
  echo $ci->output->get_output();
  exit(4);
}
