在WooCommerce订单详细信息中显示父分组产品名称

Question

对于Woocommerce分组产品，我使用以下代码在购物车和结帐页面中显示父产品名称：

// Adding the grouped product ID custom hidden field data in Cart object
add_action( 'woocommerce_add_cart_item_data', 'save_custom_fields_data_to_cart', 10, 2 );
function save_custom_fields_data_to_cart( $cart_item_data, $product_id ) {

if( ! empty( $_REQUEST['add-to-cart'] ) && $product_id != $_REQUEST['add-to-cart'] ) {
    $cart_item_data['custom_data']['grouped_product_id'] = $_REQUEST['add-to-cart'];
    $data['grouped_product_id'] = $_REQUEST['add-to-cart'];

    // below statement make sure every add to cart action as unique line item
    $cart_item_data['custom_data']['unique_key'] = md5( microtime().rand() );
    WC()->session->set( 'custom_data', $data );
}
return $cart_item_data;
}


// Add the parent grouped product name to cart items names
add_filter( 'woocommerce_cart_item_name', 'custom_product_title_name', 10, 3 );
function custom_product_title_name( $cart_item_name, $cart_item, $cart_item_key ){
// Only in cart and checkout pages
if ( is_cart() || is_checkout() )
{
    // The product object from cart item
    $product = $cart_item['data'];
    $product_permalink = $product->is_visible() ? $product->get_permalink( $cart_item ) : '';

    // The parent product name and data
    if( ! empty( $cart_item['custom_data']['grouped_product_id'] ) ){
        $group_prod_id = $cart_item['custom_data']['grouped_product_id'];
        $group_prod = wc_get_product($group_prod_id);
        if ( ! $group_prod->is_type( 'grouped' ) ) return $cart_item_name;
        $parent_product_name = $group_prod->get_name();
        $group_prod_permalink = $group_prod->is_visible() ? $group_prod->get_permalink() : '';

        if ( ! $product_permalink )
            return $parent_product_name . ' > ' . $product->get_name();
        else
            return sprintf( '<a href="%s">%s</a> > <a href="%s">%s</a>', esc_url( $group_prod_permalink ), $parent_product_name, esc_url( $product_permalink ), $product->get_name() );
    }
    else
        return $cart_item_name;
}
else
    return $cart_item_name;
}

代码来源于此：将父产品名称添加到WooCommerce中的每个购物车项目名称中

现在，我想在订单详细信息和后端也显示此父产品名称。

我将感谢任何对此的帮助。

我重新访问了原来的代码答案位，我已经启用了这些母产品链接名称的订单和电子邮件通知显示：

// Adding the grouped product ID custom hidden field data in Cart object
add_filter( 'woocommerce_add_cart_item_data', 'save_custom_fields_data_to_cart', 20, 2 );

    if( ! empty($_REQUEST['add-to-cart']) && $product_id != $_REQUEST['add-to-cart']
    && is_numeric($_REQUEST['add-to-cart']) ){
        $group_prod = wc_get_product($_REQUEST['add-to-cart']);
        if ( ! $group_prod->is_type( 'grouped' ) )
            return $cart_item_data; // Exit

        $cart_item_data['grouped_product'] = array(
            'id' => $_REQUEST['add-to-cart'],
            'name' => $group_prod->get_name(),
            'link' => $group_prod->get_permalink(),
            'visible' => $group_prod->is_visible(),
        );

        // Below statement make sure every add to cart action as unique line item
        $cart_item_data['grouped_product']['unique_key'] = md5( microtime().rand() );
    }
    return $cart_item_data;
}
