Php 为什么woocommerce中的感谢页面不'；你不能正常工作吗？

为什么订购的物品没有出现在我的感谢页面中？与往常一样，没有发票明细。。我不知道为什么，现在它只是一个消息而已。。几周前，发票详细信息出现并可以正常工作

我想错误代码在woocommerce/checkout的thankyou.php上

我发现变量$order无法读取，因此if子句被跳过到else子句。。然后它只显示thankyou.php中代码底部的消息（下面是代码）

我的目标是在我的感谢页面中显示发票详细信息，而不仅仅是信息

<?php
/**
 * Thankyou page
 *
 * This template can be overridden by copying it to yourtheme/woocommerce/checkout/thankyou.php.
 *
 * HOWEVER, on occasion WooCommerce will need to update template files and you
 * (the theme developer) will need to copy the new files to your theme to
 * maintain compatibility. We try to do this as little as possible, but it does
 * happen. When this occurs the version of the template file will be bumped and
 * the readme will list any important changes.
 *
 * @see         https://docs.woocommerce.com/document/template-structure/
 * @author      WooThemes
 * @package     WooCommerce/Templates
 * @version     2.2.0
