I have a CodeIgniter application that's generally working how I'd like it to, but occasionally a user will go to a page that does not exist and is greeted with an unfriendly error. I'd like to detect the error automatically and display useful information to the user (not PHP errors). I read the user guide of CodeIgniter, but I couldn't find any relevant section.
How do I handle a page-not-found error in CodeIgniter and display my own custom content?
You should test for error return values and catch exceptions. This is a general programming concept - not something specific to Conigniter or PHP.
Testing for error return values:
Catching exceptions:
Of course write useful error messages with pertinent info that helps the user find their problem, and/or helps you fix your bug. You could get advanced and use something like set_error_handler(): http://php.net/manual/en/function.set-error-handler.php
I found this interesting article: http://www.derekallard.com/blog/post/error-handling-in-codeigniter/
I'm not sure it reflects the current CI release as it's from 2007.
If you're looking at handling errors with your own custom page, you can modify the error templates found in
application/errors
. If you have a reason to based on your own code, you can manually send the user to one of these pages usingshow_404
orshow_error
- check out the Error Handling page in the official docs.Try these codeigniter functions
