Well in that case you probably want something like this (after you've checked to see whether the user is logged in etc): $sql = "UPDATE users SET money = money - 10 WHERE id = " . $_SESSION['user_id'];
this does not check if the user has enough money. This query does: UPDATE users SET money = money - 10 WHERE id = $_SESSION['user_id'] and money >= 10 Then check affected rows to see if the money was actually subtructed from the account.
