How can I redirect a 404 Error in a custom 404 page using Codeigniter?

Question

Kind sirs, I'm using Codeigniter to build a blog. I might need a way to redirect a 404 error into a custom 404 page. Just like what Abduzeedo.com's 404 page. Is it possible to control this by using routes? Or should i use controllers to direct it to another view? Thanks very much!

Answer 1

there is another way which I use: by overriding Exception core class of Codeigniter. Firstly make sure your config file(system/application/config/config.php) subclass prefix is as following $config['subclass_prefix'] = 'MY_';

Then make a file named MY_Exceptions.php in system/application/libraries. Then override the function show_404() function here as follows.

class MY_Exceptions extends CI_Exceptions{     function MY_Exceptions(){         parent::CI_Exceptions();     }      function show_404($page=''){              $this->config =& get_config();         $base_url = $this->config['base_url'];          $_SESSION['error_message'] = 'Error message';         header("location: ".$base_url.'error.html');         exit;     } } 

Now Error controller will be your error page, where the page will be redirected for 404 error.
