action to update menu_order to database

We’re using Category Order and Taxonomy Terms Order to sort groups of posts, and the order is saved so clearly the ajax script works. However, when we installed about a year ago we had a function to save the order to the database menu_order column. That stopped working. Do you have a suggestion for a function that will work to post the menu_order values?

Here’s my old function that stopped working:

add_action ( ‘wp_ajax_save_menu_order’, ‘menu_order_save’ );
function menu_order_save () {
global $wpdb;
$wpdb->flush ();
$item_id = $_POST[‘post_id’];
$meta_key = ‘_menu_order’;

$int = preg_replace(“/[^0-9]/”, “”, $_POST[‘order’]);

update_post_meta ( $item_id, $meta_key, array ( ‘menu_order’ => $int ) );

$response = ‘

Post order updated’;
echo $response;

die(0);
}
