在 WooCommerce 中各处的项目名称下显示产品类别和“品牌”属性术语名称

Question

我想在购物车/结帐页面的产品名称下显示每个产品的类别和属性（品牌）

示例：
“产品名称”
"类别 | 品牌"
As shown in this image from shop

我想在 cart page
上以同样的方式显示它 （还有Thank you page + Order details，但这些优先级较低）

我有这段代码可以将类别添加到购物车页面，但是如何在它旁边添加属性/品牌？ Refer to this image

add_filter( 'woocommerce_cart_item_name', 'category_under_at_cart', 99, 3);
 
function category_under_at_cart( $name, $cart_item, $cart_item_key ) {
 
$product_item = $cart_item['data'];
 
// make sure to get parent product if variation
if ( $product_item->is_type( 'variation' ) ) {
$product_item = wc_get_product( $product_item->get_parent_id() );
} 
 
$cat_ids = $product_item->get_category_ids();
$attributes = $product_item->get_attributes();
 
// if product has categories, concatenate cart item name with them
if ( $cat_ids ) $name .= '</br>' . wc_get_product_category_list( $product_item->get_id(), ', ', '<span class="posted_in">' . _n( count( $cat_ids )) . ' ', ' | ','</span>');
 
return $name;
 
}

以下将在 minicart、购物车、结帐、客户订单和电子邮件通知上显示格式化的产品类别和产品属性“品牌”术语名称：

// Custom funtion that return the formatted category(ies) and attribute 'brand' term names
function get_categories_and_brand_html( $product_id ){
    $product    = wc_get_product($product_id);
    $cat_names  = (array) wp_get_post_terms( $product_id, 'product_cat', ['fields' => 'names'] );
    $brand_name = $product->get_attribute('brand');
    $output     = '';

    if ( ! empty($cat_names) || ! empty($brand_name) ) {
        $output .= '</br><span class="posted_in">';

        if ( ! empty($cat_names) ) {
            $output .= implode(', ', $cat_names);
        }

        if ( ! empty($cat_names) && ! empty($brand_name) ) {
            $output .= ' | ';
        }

        if ( ! empty($brand_name) ) {
            $output .= $brand_name;
        }
        $output .= '</span>';
    }
    return $output;
}

// Display term names in minicart and cart page
add_filter( 'woocommerce_cart_item_name', 'category_brand_after_cart_item_name', 100, 3 );
function category_brand_after_cart_item_name( $item_name, $cart_item, $cart_item_key ) {
    $terms_html = get_categories_and_brand_html( $cart_item['product_id'] );

    if ( ! is_checkout() && ! empty($terms_html) ) {
        $item_name .= $terms_html;
    }
    return $item_name;
}

// Display term names in checkout page
add_filter( 'woocommerce_checkout_cart_item_quantity', 'category_brand_after_checkout_item_name', 100, 3 );
function category_brand_after_checkout_item_name( $quantity, $cart_item, $cart_item_key ) {
    $terms_html = get_categories_and_brand_html( $cart_item['product_id'] );

    if ( is_checkout() && ! empty($terms_html) ) {
        $quantity .= $terms_html;
    }
    return $quantity;
}

// Display term names on customer orders
add_filter( 'woocommerce_order_item_quantity_html', 'category_brand_after_order_item_name', 100, 2 );
function category_brand_after_order_item_name( $item_name, $item ) {
    $terms_html = get_categories_and_brand_html( $item->get_product_id() );

    if ( is_wc_endpoint_url() && ! empty($terms_html) ) {
        $item_name .= $terms_html;
    }
    return $item_name;
}

// Display term names on email notifications
add_filter( 'woocommerce_order_item_name', 'category_brand_after_email_item_name', 100, 3 );
function category_brand_after_email_item_name( $item_name, $item, $is_visible ) {
    $terms_html = get_categories_and_brand_html( $item->get_product_id() );

    if ( ! is_wc_endpoint_url() && ! empty($terms_html) ) {
        $item_name .= $terms_html;
    }
    return $item_name;
}
