Answer 1

I have simplified the code to illustrate how to create dynamic UPDATE query. This uses "lazy" binding and regular placeholders ?.

The text inputs are set as a regular array (ie. not associative) of values.

";
        print_r($query_params);
        // Execute the query
        $stmt = $db->prepare($query);
        $result = $stmt->execute($query_params);
    }
}
?>

 

Typical result

UPDATE `users` SET `info1` = ?,`info2` = ? WHERE `id` = ?
Array ( [0] => john [1] => smith [2] => johnsmith )
