404 Override Not Working

If you create the file: application/core/MY_Exceptions.php with the following code what happens?

PHP Code:

<?php


class MY_Exceptions extends CI_Exceptions {

 function __construct() {

 parent::__construct();

 }

 public function show_404($page = '', $log_error = TRUE)
 {
 if (is_cli())
 {
 $heading = 'Not Found';
 $message = 'The controller/method pair you requested was not found.';
 }
 else
 {
 $heading = '404 Page Not Found';
 $message = 'The page you requested was not found.';
 }

 
 if ($log_error)
 {
 log_message('error', $heading.': '.$page);
 }
 
 if( is_cli() ) {

 echo $this->show_error($heading, $message, 'error_404', 404);

 } else {
 header("HTTP/1.0 404 Not Found");
 
 
 header('location: http://www.yoursite.com/notfound');

 }
 exit(4); // EXIT_UNKNOWN_FILE
 }

} 


dont forget to replace www.yoursite.com with your applications domain. If it works you'll need to change how the base_url is passed in but this should be enough to see if it makes progress towards a solution.

Thanks that works also.

This will work, but you are both missing the fact that the 404_override and show_404 are not directly related. Setting the one does not change the workings of the other. IMHO changing the show_404 to fix something that is not broken because of a lack of knowledge is not the way to do things.

Instead create a show_notfound() method that will handle the redirect to your custom Controller. This way you can keep using the show_404 as is, also within your custom Controller without causing an infinite redirect loop.
