How can we display order items by products's menu_order

Hello Anand, is ‘menu_order’ a custom field in the product? You could try something like this (you will probably need to load the menu_order separately).

Hope that helps!

Yes I saw your previous post related to sku, but that is regrading ordermeta.

menu_order is not a custom field, its general field when we add woocommerce product we can assign product to desired order. menu_order save in post table.

Hi Anand,
In that case I would add the menu_order to the item data using the wpo_wcpdf_order_item_data filter, something like this:

add_filter( 'wpo_wcpdf_order_item_data', 'wpo_wcpdf_order_regular_price', 10, 2 );
function wpo_wcpdf_order_regular_price ( $item_data, $order) {
    if (!empty($item_data['product']->post)) {
        $item_data['menu_order'] =$item_data['product']->post->menu_order;
    } else {
        $item_data['menu_order'] = '';
    }
    return $item_data;
}

then sorting by that value.

Hope that helps!
