Login / Auth function always checked

[eluser]internut[/eluser]
Sorry if I've missed this. If so would you please point me in the right direction?

I'm progressing well but am looking at how I can first make sure a session var is set before progressing and allowing functions to run.

Basically a login check function that is called and checks if user is logged in before moving around functions / controllers.

noob I know.

would this be not the right way to go about it at the beginning of each controller function:

Code:

if(!$this->session->userdata('logged_in')) {
            redirect('');
        }

You could always create a function i.e. $this->auth->user_only() that you can call through the controller and that'll check if the user is logged in.

Meaning:

Controller: auth.php

function within it of:

Code:

function user_only {
  // check is session var set?
}

I'm pretty sure I'm off. Any pointers greatly appreciated.

Trying to understand where the function should go (if i'm wrong) and how to call it.

Or is there a better way to before any controller / function is executed to first check a login.

Create a library/plugin/helper that's loaded globally and then create a function that'll do your session check and then call that from the controller you want to be user_only. A more elaborate method would be having this function get the page url, then redirect if the user isn't logged in, once the user is logged then you can redirect back

Its basically this:

Login Page

---> Rest of program here (not a few functions / controllers but all)

So should I go crazy with creating a function or just place the following in each function:

Code:

if(!$this->session->userdata('logged_in')) {
   redirect('');
}

Michael Wales uses a good method. Extend the controller class with something like Public_controller and Admin_controller. The public controller / admin controller looks up whether the user is logged in. If you want someone to be able to use a specific controller, make it publig, otherwise make it an admin controller, or loggedin_controller, etc.
