在Woocommerce订单详细信息和所有电子邮件中显示高级自定义域值

Question

我用ACF插件创建了一个高级定制字段，以便在Woocommerce产品编辑页面上添加附加信息。这是一个区分T恤模板的副标题。我能够使价值出现在产品页面前端，但我需要这些信息出现在订单细节和所有电子邮件中，也许作为订单元。提前谢了。

请在fucntions.php文件中尝试下面的代码..

 add_action( 'woocommerce_before_add_to_cart_button', 'add_custom_field', 0 );

function add_custom_field() {
    global $product;             // Changed this

    // Added this too (compatibility with WC +3) 
    $product_id = method_exists( $product, 'get_id' ) ? $product->get_id() : $product->id;

    echo "<div class='produto-informacoes-complementares'>";
    echo get_field( 'woo_title', $product_id );
    echo "</div>";

    return true;
}


add_filter( 'woocommerce_add_cart_item_data', 'save_my_custom_product_field', 10, 2 );

function save_my_custom_product_field( $cart_item_data, $product_id ) {

    $custom_field_value = get_field( 'woo_title', $product_id, true );

    if( !empty( $custom_field_value ) ) 
    {
        $cart_item_data['woo_title'] = $custom_field_value;

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

add_filter( 'woocommerce_get_item_data', 'render_meta_on_cart_and_checkout', 10, 2 );

function render_meta_on_cart_and_checkout( $cart_data, $cart_item ) {
    $custom_items = array();
    // Woo 2.4.2 updates
    if( !empty( $cart_data ) ) {
        $custom_items = $cart_data;
    }
    if( isset( $cart_item['woo_title'] ) ) {
        $custom_items[] = array( "name" => "ACF value:", "value" => $cart_item['woo_title'] );
    }
    return $custom_items;
}

function add_order_item_meta_acf( $item_id, $values ) {

    wc_add_order_item_meta( $item_id, 'acf', $values [ 'woo_title' ] );
  }
add_action( 'woocommerce_add_order_item_meta', 'add_order_item_meta_acf' , 10, 2);

在订单表之后显示订单详细信息页面中的Acf值

add_action ('woocommerce_order_details_after_order_table', 'order_detail_page', 20);

  function order_detail_page($order_id) {

    //  global $post;
    // $order = wc_get_order( $post->ID ); 

     $order = new WC_Order( $order_id );
     $items = $order->get_items();
     foreach ( $items as $item ) {
          $product_id = $item['product_id']; 
         }

  if (get_field('woo_title',  $product_id)) {
   ?>
    <p class="WooCommerce">ACF value: <?php the_field('woo_title',  $product_id);    ?><p>      
    <?php 
     }
   }```
