add date of booking

Hi! To display the WooCommerce Bookings data, you have two options:

1) With the Premium Templates extension you can check the “Show external plugin data” option in the Product block.
2) With a custom code snippet (works with the free version too):

add_action( 'wpo_wcpdf_after_item_meta', 'wpo_wcpdf_show_product_booking_data', 10, 3 );
function wpo_wcpdf_show_product_booking_data ( $template_type, $item, $order ) {
    do_action( 'woocommerce_order_item_meta_end', $item['item_id'], $item['item'], $order );
}

If you haven’t worked with code snippets (actions/filters) or functions.php before, read this guide: How to use filters

Hope that helps!
