why thank you page in woocommerce doesn't work properly? - php

Question

why the ordered items doesn't appear in my thankyou pages? there is no invoice detail as usual.. i don't know why, now it's only a message only.. several weeks ago, invoice detail appears and can work properly..
i think the error code is at thankyou.php at woocommerce/checkout
i find that variable $order cannot be read, so the if clause is skipped to the else one.. then it only shows the messages in the bottom of codes in thankyou.php (below is the codes)
my goal is to show the invoice detail in my woocommerce thank you pages, not only the messages.
<?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
