Just try to inspire yourself with the code below. Also try to safe your data with simple add-on:

$test = mysql_real_escape_string($values['item_name']);

You may come alright:

function db_action($data = array()) {
    switch ($data['action']) {
        case 'insert':
            $keys = array(); $values = array();

            foreach ($data['data'] as $key => $value) {
                $keys[$key] = $key;
                $values[$key] = "'".$value."'";
            }

            $keys = implode(', ', $keys);
            $values = implode(', ', $values);
            mysql_query("INSERT INTO ".$data['table']." (".$keys.") VALUES (".$values.")");
            break;
        case 'update':
            mysql_query("UPDATE ".$data['table']." SET ".$values." WHERE ".$key." = ".$id);
            break;
        case 'delete':
            mysql_query("DELETE FROM ".$data['table']." WHERE ".$key." = ".$id);
            break;
    }

    return;
}
