To implement postback functionality, you'll need a script on your server that is called when someone votes for you. Below is a PHP example for basic integration based on the default callback.
This method works for most of our website users. Simply pass the voter’s username/ID along with the vote link.
[YOUR-SERVER-VOTE-URL]?user=[PLAYER-ID]
[YOUR-SERVER-VOTE-URL] with your server setting.
[PLAYER-ID] with the ID that you use to identify your player.

#Example PHP Postback Script
// Your Database Connection Details
$host = 'localhost';
$db_name = '';
$db_user = '';
$db_password = '';
$connection = mysqli_connect($host, $db_user, $db_password);
mysqli_select_db($connection, $db_name);
// User
$userid = isset($_POST['userid']) ? $_POST['userid'] : null;
// User IP
$userip = isset($_POST['userip']) ? $_POST['userip'] : null;
// User voted on Gamehot? 1 = unique vote, 0 = already voted
$valid = isset($_POST['voted']) ? (int)$_POST['voted'] : 0;
// Make sure the user was not yet rewarded on your system
// For example by checking your reward logs
if (!is_null($userid) && $valid == 1)
{
// Make userid safe to use in query
$userid = mysqli_real_escape_string($connection, $userid);
// COUNT rows where reward_date is today
$result = mysqli_query($connection, "SELECT COUNT(*) FROM `reward_log` WHERE `user` = '$userid' AND `reward_date` >= CURDATE()");
$rewarded = mysqli_num_rows($result);
// No results means not rewarded yet, so grant reward and set the reward date/time log
if(!$rewarded)
{
// Grant reward, for example vote points
mysqli_query($connection, "UPDATE `users` SET `points` = `points` + 1 WHERE `user` = '$userid'");
// Insert log
mysqli_query($connection, "INSERT INTO `reward_log` (`user`, `reward_date`) VALUES ('$userid', NOW())");
}
}
// Close connection
mysqli_close($connection);
