I use only this single line of code in my error template file (/system/application/errors/error_404.php):

http://' . $_SERVER['HTTP_HOST'] . '/home/page_not_found');

No need of extending any CI core classes. If you need to show your own error page at the web server level (i.e. when accessing resources not parsed by your CI installation), you could also do something like this (depending on your host configuration of course):

ErrorDoc 404 /home/page_not_found

Hope this helps!

That's an interesting approach Jeremy - it certainly seems cleaner to me if it works... As mentioned above, I now use Kohana and can handle 404s in a much cleaner way but your suggestion may be useful for anyone who uses CI...

That's an interesting solution.

I, too, decided on a custom error controller/method.

Did you consider using apache's ErrorDocument statement to decide how to route the error?

For example, I have the following:

ErrorDocument 404 /index.php/main/page_not_found

I'm afraid that I've stopped using Code Igniter (I now use Kohana 3)... It is a lot more graceful and easier there (you can throw and error and catch it and display the 404 page at the base render level).

However, I did run into this problem when I was using CI and the simple solution I used was to pass an additional get parameter in the CURL request - something like ?isAdmin=1. This would display the admin link (and is still secure because the link only actually works if you are logged in),

Hope it helps,

Kelvin :)

Hi Kevin

I really like your solution the only issue I now have is that the session id changes (because of using CURL I assume) so if I'm logged in to my admin panel and then click on a link that generates a 404 error I lose my admin menus.

I can't see any way around this, any ideas?

Hi Kelvin. I've been reading the codeigniter forums trying to figure out the best solution to handle 404 errors and I found your approarch very interesting. Im using it now in my website, but I dont fully understand one thing about your implementation. You use this route to handle 404's: $route['(:any)'] = "home/$1"; But it doesnt work for me adding the last "/$1". Actually, how could it possibly work with "$1"? Using just : $route['(:any)'] = "errorController"; makes sense to me. If you add the last "/$1", how does it know which function of the controller should it use? It would be different every time. I hope you understand my question :P Thanks for your idea and your time!

I just use $_SERVER['HTTP_HOST'] and $_SERVER['REQUEST_URI']...

Am I being dim? How did you echo out the 'not found' URL in your view file in the example i.e.:
