Facebook passes in your data as part of the signed_Request data. Here is how you would retrieve it using PHP:

<?php 
require 'facebook.php';
$app_id = "YOUR APP ID HERE";
$app_secret = "YOUR SECRET KEY HERE";


$facebook = new Facebook(array(
        'appId' => $app_id,
        'secret' => $app_secret,
        'cookie' => true
));


// THE MAGIC SAUCE
$signed_request = $facebook->getSignedRequest();

$page_id = $signed_request["page"]["id"];
$like_status = $signed_request["page"]["liked"];
// HERE IS A STRING OF YOUR APP DATA.
$app_data = $signed_request["app_data"];

echo '$app_data = '.$app_data;
?>

This example requires the Facebook PHP api and will write your app_data into the browser window where you can marvel in all its glory.


Oh wow, I didn't know about the app_data parameter.Here's another method for whatever it's worth: http://iamskwerl.com/tech/2011/11/passing-query-variables-to-facebook-fan-page-tabs/


There is a solution available although I have not tried it but hope it works http://ikorolchuk.blogspot.com/2011/03/facebook-fan-page-pass-parameter-to.html
