我正在使用 WordPress 插件“ WooCommerce Gift Coupon ”，它會生成一個 PDF 作為附件通過郵件發送給客戶。我想在該 PDF 中顯示當前日期，并且已經找到要編輯的 php 文件（mail-template.php）。我嘗試將以下代碼放置在 body 標記內的多個位置，但沒有成功：<?php $currentDateTime = date('Y-m-d H:i:s'); echo $currentDateTime;?>我也嘗試過不打開和關閉 php 標簽。我要么收到錯誤，要么顯示 PDF 文檔中的代碼。這是mail-template.php的完整代碼：

該模板將所有 HTML 保存到一個變量 ( $email) 中，稍后將其轉換為 PDF。如果您添加了此內容，則無需回顯它。下面的模板應該可以工作。
<?php
/**

*
* Sets up the email template
*
* @author WooCommerce Gift Coupon
* @package WooCommerce Gift Coupon/Mail Template
*/
if ( ! defined( 'ABSPATH' ) ) {
exit;
}
/**

*
* @param array $data Coupon data.
* @param bool $preview Check if is preview.
* @return string
