I had found the way to print the user ID, photo and name. And other type of info easily with PHP but I didn't save the link and can't find how to do it.
I only want to know what's the simplest method to get the User's ID. I need to save it to my database in here:
<?php
// Get new icon
mysql_select_db("cyberworlddb", $con);
mysql_query("INSERT IGNORE INTO Badges (UID, Website, Code)
VALUES ('UID','$urlhost[0]','1$urlhost[0]')");
?>
How can I do it?
If they are logged into your Facebook application you can get their session token from the facebook cookie (http://developers.facebook.com/docs/authentication/) and then you just use the graph api:
$me = json_decode(@file_get_contents('https://graph.facebook.com/me?access_token=' . $cookie['access_token']));
$uid = $me->id;
