我在跟踪Xatic的tutorial 帮助我向产品添加自定义数据。

我已经设法在购物车页面上显示了这些数据。但是，它不会显示在管理后端的订单页面中。

我能做些什么来解决这个问题？

这是我到目前为止得到的

add_action( \'wp_enqueue_scripts\',\'enqueue_wc_scripts\' );
add_action(\'woocommerce_before_add_to_cart_button\',\'extend_product_options\');
add_filter(\'woocommerce_after_single_product_summary\',\'prescription_form\');

add_filter(\'woocommerce_add_cart_item_data\', \'custom_add_item_data\', 10, 2);
add_filter(\'woocommerce_get_cart_item_from_session\',\'wc_get_cart_item_from_session\',10,2);
add_filter(\'woocommerce_get_item_data\', \'xatik_wc_get_item_data\', 10, 2);

add_action(\'woocommerce_add_order_item_meta\', \'xatik_wc_order_item_meta\', 10, 2);

load_child_theme_textdomain(\'yit\', get_stylesheet_directory().\'/languages\');
