Solution 1

You could try something like:

mysql_query("UPDATE secretcodes SET uses=uses + ".$credits2." WHERE secretcode='".$secretcode."'")

However, that would be a potential security risk because of SQL injections etc. So perhaps a better approach would be to investigate MySQL improved extension[^]
