在电子邮件通知 WooCommerce 中显示自定义订单元数据值

Question

基于以下代码

我尝试将 my_field_name 添加到订单确认电子邮件中。据我了解，我必须使用 woocommerce_email_customer_details.

所以我找到了这个解决方案，不幸的是没有得到想要的结果。

add_action('woocommerce_email_customer_details','woocommerce_email_order_invoice_number', 28, 4 );
function woocommerce_email_order_invoice_number( $order, $sent_to_admin, $plain_text, $email ) {
  if( $my_field_name = get_post_meta( $order->get_id(), 'my_field_name', true ) ) 
      echo '<p><strong>My custom field: </strong> <span style="color:red;">Is enabled</span></p>';
}

你有一些小错误，通过 if 条件 "$email->id == ..." 你可以定位邮件
