How to have a called controller on every page in CodeIgniter

Question

I want to have a controller to do some initial settings and fetch some basic data in all of my application pages (written with PHP and CodeIgniter). As I'm new in CI, please help me to do it.
Some of my goals to have such controller:

1. Setup submenus (regardless of the current page)
2. Check user login status.

Notice:

I don't have any problem on creating and working with general Controllers in CI. What I need is something like a hidden controller that does not any need to URI segments to run, and it is not the CI default controller too.

Answer 1

What you can do is create a base controller and and extend that base controller in every other controllers instead of CI_Controller . Your base controller will extend CI_Controller . You can add your required checks in the constructor of the base controller and do stuffs according to that. So every time you call a controller your checks will be done. But you have autoload the base controller. I hope this helps you.
