Since this is the only thing that match an integer value, try to use
$id = $_POST['id'] + 0;
in case there is no id sent. You'll don't get any results [i hope there is
no id==0] but u'll don't have an error on your query.
Because id is integer try not to use *where id='$id'*. Use *where id=$id*
instead.
