I would like to hear from someone who has successfully implemented a custom error tracking system with db logging and custom 404 pages. what I'm trying to accomplish is:
1) Saving errors to a db table. I'm partially able to accomplish this by extending the exceptions class. please see below.
2) show a custom 404 page. I'm partially able to accomplish this by extending the router class. please see below. I say partially because this system seems to work when I input a totally fake URL. i.e.:
www.domain.com/nonexistent. however, if I do something like this:
www.domain.com/media/video/shownonexistent where
www.domain.com/media/video/show points to a real controller functions, CI shows the default 404 page.
I would like to start a discussion on how to effectively build a custom error tracking and 404 pages as I believe many others will benefit from it.
with regard to #1, is extending the exceptions class the proper way to approach this?
thanks in advance
