404 Help

How can I use a custom 404 page and still set the header status to 404?
The custom 404 in routes.php:

Code:

$route['404_override'] = 'my_controller/custom_404';

If I set the header status to 404, my custom error method shows the regular ugly server error 404 page.

Code:

function custom_404 () {
$this->output->set_status_header('404');
$this->load->view('my_error');
}

But if I do not set the header to 404 (pointless), my custom error works.

Code:

function custom_404 () {
//$this->output->set_status_header('404');
$this->load->view('my_error');
}

I see examples where folks have loaded a view or sent some other output after setting the header status to 404... how can I do that?

cant you just edit application/errors/error_404.php?

Try a regular header() and not use CI's for that one case.
header("HTTP/1.0 404 Not Found")

You can also put it at the very top of your view.

Ok, it turns out I was actually seeing an IIS error page. Now I've redirected the server 404 page to my custom controller but now when I set the header:

Code:

function custom_404 () {
$this->output->set_status_header('404');
//or header("HTTP/1.0 404 Not Found");
$this->load->view('my_error');
}

All I get is a blank page. So the page header is working but I am still unable to load a view after setting it.

I did originally try that. Strangely, editing that file has no effect at all.

Update: Appears to be an IIS issue (surprise). IIS apparently won’t do a second http request after a 404 status is set. Instead, it will look for the file specified in IIS as the custom error page.
