There are two ways you can redirect the client browser.  One is with the header() function.  The other is to put a meta-refresh tag into the browser output stream.  The latter method is "deprecated" however I have never encountered a browser that did not obey the command.

See these links for specifics:

What I mean is I have to redirect after logging out on facebook.com

I tried this but it does not work

$facebook->getLogoutUrl( array(
    'redirect_uri'  => 'http://www.mydomain.com/fblogout.php')
);

Open in new window

---------------------
home.php

require 'facebook.php';
require 'fbconfig.php';
session_start();
$facebook=$_SESSION['facebook'];
$userdata=$_SESSION['userdata'];
$logoutUrl=$_SESSION['logout'];

//$logoutUrl = $facebook->getLogoutUrl(array('next' => $logoutUrl, 'session_key' => $session_key));


//$logoutUrl = $facebook->getLogoutUrl( array(
//    'redirect_uri'  => 'http://www2.mydomain.com/fblogout.php')
//);

Open in new window


-----------------
fbconfig.php

<?php
$facebook_appid='xxxxx';
$facebook_app_secret='xxxxx';
$facebook = new Facebook(array(
'appId' => $facebook_appid,
'secret' => $facebook_app_secret,
));
?>

You can specify in your facebook app setting what you want the return URL to be.

instead of this,
$facebook->getLogoutUrl( array(
    'redirect_uri'  => 'http://www.mydomain.com/fblogout.php')
);

try,

echo "<script>window.location = 'http://www.mydomain.com/fblogout.php'</script>";

Ah, in that case I would make the link go to your logout page, that then redirects or has the facebook logout code in it.

Send user to your log out page
Log out page sends them to facebook log out

If I send them to my logout page first, how can I send them to facebook page if the session has already been destroyed?
