A question on' action'

klik

hi, my two files are below

part of my functions.php file

if ($action == "logout") {  // just incase user wants to logout

      session_unregister("username");
        session_unregister("password");
        session_unset();
      session_destroy();

	echo("Thank you, You have been signed out");

	exit;

}

part of my index.php file

[<a href="index.php?action=logout">Logout</a>]

I'm pretty sure this isn't how you perfom an action, but just wondering if someone can point me in the right direction.

Whats so wrong about that? The only problem here is your using $action instead of $_GET['action']

EDIT

How can I return an echo statement to the page the 'logout' link was clicked from?

planetsim

Echo outputs by itself if you used return it would return as 1 (meaning the right of the return was successful).

From what i see if say i go to

index.php?action=logout

Your if statement should go hey this is a match to the logout action so it destroys the session then should say im signed out.

If that isnt working then you may have something else where in your script preventing it, which I cannot see.

^ indeed it does now.

But I would like my 'thank you, you have logged out' statement to be positioned some where else on my page, instead of echoing to the very top of the page. Can i control where this statement is echoed to?
