Display order item estimated delivery date if product has specific custom field in WooCommerce

Question

I'm adding programmatically a product custom field (the estimated delivery date) as custom cart item data if the product is ordered from backorder.

I want to display that information also on order items so it will be displayed on orders and email notifications sent to customer.

Here's what i tried so far :

add_filter( 'woocommerce_get_item_data', 'display_acf_on_cart_and_checkout', 10, 2 );
function display_acf_on_cart_and_checkout( $cart_data, $cart_item ) {
    if ( ($cart_item['variation_id'] > 0 && $cart_item['data']->get_stock_quantity() <= 0
    && $cart_item['data']->get_meta('_ab_preorder_checkbox') === 'yes') || isset( $cart_item['is_preorder_field'] ) ) {
        if ( $estimated_delivery_date = $cart_item['data']->get_meta('_ab_preorder_estimated_date') ) {
            $custom_items[] = array( "name" => __("Date de livraison estimée (précommande) ", "woocommerce"),  "value" => $estimated_delivery_date );
        }
    }
    return $custom_items;
}

The message is showing on the cart and on the checkout page :

But not on the invoice/emails sent to the client :

I would like it to show up on like on the screenshot below (in the red rectangle). Is it possible?

Any help is appreciated.

Please put some effort into showing us what you tried so far. — Bhautik

You can use the following to save the estimated delivery date for preordered items as custom order item meta data and display it on orders and email notifications:

// Save as custom order item meta data and display on orders and email notifications
add_action('woocommerce_checkout_create_order_line_item', 'action_checkout_create_order_line_item', 10, 4 );
function action_checkout_create_order_line_item( $item, $cart_item_key, $values, $order ) {
    if ( ($values['variation_id'] > 0 && $values['data']->get_stock_quantity() <= 0
    && $values['data']->get_meta('_ab_preorder_checkbox') === 'yes') || isset( $values['is_preorder_field'] ) ) {
        if ( $estimated_delivery_date = $values['data']->get_meta('_ab_preorder_estimated_date') ) {
            $item->update_meta_data( 'is_preorder', $estimated_delivery_date );
        }
    }
}

// Change required displayed meta key label to something readable
add_filter('woocommerce_order_item_display_meta_key', 'filter_order_item_displayed_meta_key', 20, 3 );
function filter_order_item_displayed_meta_key( $displayed_key, $meta, $item ) {
    // Change displayed meta key label for specific order item meta key
    if( $item->get_type() === 'line_item' && $meta->key === 'is_preorder' ) {
        $displayed_key = __("Date de livraison estimée (précommande) ", "woocommerce");
    }
    return $displayed_key;
}

Code goes in functions.php file of the active child theme (or active theme). It should work.
