User Authentication

[eluser]Moon 111[/eluser]
If I were to make a user authentication system, where would I check if the user is signed in?

Obiously I don't want to have an if expression in every controller. How would I do this?

Some help would be wonderful.

Look into the Wiki for a "Loader" library.
I put it in there - in the constructor.

Create a library which is autoloaded by Codeigniter and perform your tasks there,.

Or use controller inheritance. All secure pages would extend a parent controller that does the authentication check in its constructor.

do it in the constructor and it will check for every function within the class

How exactly would I do that?

OK, I think I've got it, but how to I make it "die" if the user isnot premitted toview the page?

Come on. You know, I choose CI because of the "amazing community" it's supposed to have.

So in the constructor of the parent controller, if the user isn't authenticated (check a session variable), then redirect to a login page.
