CodeIgniter Default Controller

Question

I am tring to create default controller for no matter what URL you access to.
Meaning, custom 404.

class MY_Exceptions extends CI_Exceptions
{
var $ci;

public function __construct()
{
    parent::CI_Exceptions();
    $this->ci =& get_instance();
}

function show_404($page = '')
{
  //load view here

}

}

I am getting get_instance is undefined. (because it was defined after the libraries get called)
Is there a way to create custom 404 controller in codeignigter 1.7.2 without playing with the system core code.

Thanks

"Because it was defined after the libraries get called" does not make sense. If it was defined /after/ it should be ok. — gen_Eric

Upgrade to CodeIgniter 2.0 because its stable and use:

$route['404_override'] = '';

If you just want to customize the 404 page, you can do so under the /system/application/errors/error_404.php page. The one caveat with this is that you can't use the $this object, it's strictly HTML/CSS or built-in PHP (no access to your libraries, models, etc.).

This is the page that CodeIgniter will display by default when it can't find a controller to handle a request.

Not sure if that's why you're trying to do or not, but that would be the simplest way to create a custom 404 page.

+1 assuming this is what OP wants, why bother reinventing the wheel

Thanks, I need A Controller and not HTML.

You could always put redirect('controller/function') into the errors/error_404.php page.

This should work fine. Make sure it's in the 'application/libraries' folder, and make sure your config has 'MY_' set as the custom library name.

Also, if you are doing function __construct(){}, you can do parent::__construct().
