include('config.php');
mysqli_select_db($mysqli, "real");
if ($transaction == "Success" && $currency == "USD") {
$user_ids = '".$user_id."'; $total_cred = `user_credits` +'".$package_credits."';
$add = $mysqli->prepare("UPDATE `users` SET `user_credits` = ? WHERE `user_id` = ?");
$add->bind_param('si', $total_cred,$user_ids); $add->execute();
}
代码不会抛出任何错误,也不会更新数据库。

将if块更改为
// $user_ids = '".$user_id."'; REMOVE THE statement
// $total_cred = `user_credits` + '".$package_credits."'; REMOVE THIS too
$add = $mysqli->prepare("UPDATE `users` SET `user_credits` = `user_credits` + ? WHERE `user_id` = ?");
$add->bind_param('ii', $package_credits, $user_id ); $add->execute();
让MySQL尽其所能。

试试这个:
include('config.php');
mysqli_select_db($mysqli, "real");
if ($transaction == "Success" && $currency == "USD")
{
$user_ids = '".$user_id."';
$total_cred = user_credits +'".$package_credits."';
$add = $mysqli->prepare("UPDATE users SET user_credits = ? WHERE user_id = ?");
$add->bind_param('si', $total_cred,$user_ids);
$add->execute();
}
