Hi all,

I have created a small test app - And I want to login users when they first arrive to the app - and log them out and redirect them after they have used it. Quite simple right, but using facebook php sdk - I am not able to do such a thing.

I can only login to the app, if i am logged in to my own private facebook account - so the getLoginUrl(); doesnt redirect if the user is not logged into his/her facebook account.

And the log out, and setting sessions to null, session_destroy(); etc, doesnt work at all, it seems i cant get rid of the facebook session, even after i have logged out of my own facebook page, i am still able to type the app url in the adress bar, and go straight to the app without authentication, and this is after i have logged out (or tried to..)

When i am logged in to the app, and clicking the logout link, it looks like i get logged out, cause all the adds go away, but my redirects dont work, and the actual app is still "open"/logged in to.

This is my index page where the users gets access:

<?php
ob_start();
header('Content-Type: text/html; charset=utf-8');
echo '<link rel="stylesheet" type="text/css" href="app_style.css"/>';
require("facebook.php");
?>

<script>(function(d, s, id) {

	exit();

Here is logout.php: I have tried so many things, and this is the last not working example..:

<?php
ob_start();
header('Content-Type: text/html; charset=utf-8');
echo '<link rel="stylesheet" type="text/css" href="app_style.css"/>';
require("facebook.php");

// DO I NEED TO SET COOKIE TO TRUE HERE?
// I found this on the net, and cant get it to work:
setcookie('fbs_'.$facebook->getAppId(), '', time()-100, '/', 'enkelt-webdesign.dk/facebook');
// Might be wrong url, should it be apps url?
session_destroy();
//header('Location: http://apps.facbook.com/enkelt-webdesign/logout.php');

// THE LOGIN URL IS IN A LINK FURTHER DOWN; AND NOTHING AT ALL HAPPENS WHEN CLICKED:?

</div>

It is somewhat basic functionality, that I cant get to work using facebooks php SDK

Is it done simple in javescript?

Or am I close to getting it right?
