Code to run on every page

[eluser]Unknown[/eluser]
Greetings.

I just started using Codeigniter, so I'm still learning my way around.

I've built a simple login form, and based on whether the user is logged in or not I'd like to display a link. So if the user is logged in it will show "Logout", if the user is not, it will show "Login | Register".

Now how can I set this up so that this check is performed on each page. Without having to repeat my code into every controller.

Any insight would be greatly appreciated.

You can have like a header view, which is included on every other view (look into templating)

and then in your header view have something along the lines of this:

Code:

if($this->session->userdata('logged_in') == 1) {
// echo link to logout url
}
else {
// echo links to login & register
}

Have a look at base classes:
