That check would have to move to mysqli_stmt_execute, if it is still > to be performed. If bind_param is allowed to do incomplete bind (as in your example where you supply 2 out of 3 required bound parameters) t hen there's no need for additional method, as you could simply do: if (isset($_GET['zip'])) $stmt->bind_param('s', $_GET['zip']); -- Best regards, Bruce Weirdan mailto:weirdan@gmail.com
