سؤال
i´m developing a Facebook Fanpage using PHP-SDK 3.0 and integrated a Facebook Registration Plugin. So far everthing works fine. I can store everthing.
The signed_request answered:
signed_request contents:
Array (
[algorithm] => HMAC-SHA256
[expires] => 1324xxxx400
[issued_at] => 132446xxx80
[oauth_token] => AAADRjT73VhwBALl6Gb3EVarvyGU7xxxxxxxxxxxxxxxxxxxSAUuoZAGlydkX2pH3
[registration] => Array ()
[user_id] => 10xxxxxxx5426 )
For storing the data I use the following code:
$email = $response["registration"]["email"];
$user_fbid = $response["registration"]["user_id"];
$email = mysql_real_escape_string($email);
$user_fbid = mysql_real_escape_string($user_fbid);
// Inserting into users table
$result = mysql_query("INSERT INTO member (email, userid) VALUES ($email, $user_fbid)
Here my question:
At first day the $result stored something like 214xxxx647 and next day it stores 217. But there is nothing similar like 10xxxxxxx5426

I think your problem is you are storing the user_id value into a "int" which means the maximum value that can be stored is 2147483647.
Facebook user_id's require a larger pool of numbers, therefore your should change the column datatype to BIGINT.
