hook doesn't redirect me

Is that code your actual hook?

If so, hooks are not controllers. You're not supposed to extend CI_Controller for a hook.
Also, `get_instance()` means "get the controller instance", and you're doing that from inside a controller ... the same controller that would be returned by it.

Thanks !

I had to blend in with all the examples I found.
My goal is to check if an entry in my database is at 1 and that we are a "user", to display an info ("site in maintenance") and otherwise continue normally.
AND, if an entry in my database is at 1 and you are "admin" then you can navigate normally.
Maybe my approach isn't optimal.

I don't want to change a file to "hard" to do this but I want to go through an admin interface.

Do you have a design tip? or, is the hook a good idea?

Thanks a lot
