show_404

[eluser]Lima[/eluser]
Is that possible to call function on controller when function show_404 is called.
or reroute to controller when function show_404 is called.

I have tried to modify application/errors/error_404.php but I got error

Fatal error: Call to undefined function: get_instance()

Any idea?

You could extend the router class with MY_Router and then override the behaviour of the standard routing practice.


For example take a look at the function _validate_request.

It checks if there is a controller present with the name of the url segment. It does some checking and if it can't find a controller, it sends calls the function show_404. So if you edit this to call 'yourspecific 404 controller', it should do what you want:

Code:

// MY_Router.php

function _validate_request($segments)
{
    // copy the whole function here
    // just change this part:

    $segments = array('<name of the controller>', '<name of the function>');
    return($segments);
    // show_404($segemnts[0]);
}
