Question

The idea is to catch any access to controller’s functions and, if we are authenticated, rout as normal and, if not, show the login form.

The question is, is _remap function the best place to check for access to controller’s functions and how to pass routing back to CI in case we are authenticated?

Answer 1

_remap isn’t necessary for this. You could use it, but you don’t need to.

Check for access in the __construct() method of the controller. You can get the current method via $this->router->fetch_method() and authenticate against that.

Better yet, have all your controller that need this extend a base controller (aka “MY_Controller”). You can write an Auth_Controller and do the auth check in the __construct() there. You can get the current class via $this->router->fetch_class(), as well as the method, just make sure your controllers that need this extend Auth_Controller instead of the usual CI_Controller.

If they shouldn’t have access, just redirect them where they need to go or show an error.
