I agree. What's best is to ensure the val is of the proper type before sending it to the db. Try casting it first; if the value is blank, it'll cast as 0 (though that may not be optimal, either, if your record could be 0): $query = "DELETE FROM sheet1 WHERE id = " . (int)$id; Also probably best to check if it's empty, something such as: if (!empty($id)) { $query = 'DELETE FROM sheet1 WHERE id = ' . (int)$id; } else { echo 'Argument $id was empty'; } HTH! -- Mike Johnson Smarter Living, Inc.
