Php 在新订单电子邮件通知中添加自定义链接

我正在建立一个餐馆网站。在该网站的前一个版本中，当有人想要送货时，餐馆收到的邮件中，我有一个指向谷歌地图的链接。餐厅可以很容易地使用它导航到餐厅的客户。 现在我正在更改网站，我将与woocommerce合作，但我还希望在管理邮件中提供指向谷歌地图的链接

来自旧站点的代码。（带有谷歌地图链接的超链接，名为“Map It”。）

要在woocommerce中执行此操作，我需要更改woocommerce管理新订单的模板，在地址下方添加超链接，但我不知道如何执行此操作

模板admin-new-order.php：

<?php
/**
 * Admin new order email
 *
 * This template can be overridden by copying it to 
yourtheme/woocommerce/emails/admin-new-order.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/Emails/HTML
 * @version 2.5.0
 */

 if ( ! defined( 'ABSPATH' ) ) {
    exit;
 }

 /**
  * @hooked WC_Emails::email_header() Output the email header
  */
 do_action( 'woocommerce_email_header', $email_heading, $email ); ?>

 <p><?php printf( __( 'You have received an order from %s. The order is as 
follows:', 'woocommerce' ), $order->get_formatted_billing_full_name() ); ?> 
</p>

 <?php

 /**
  * @hooked WC_Emails::order_details() Shows the order details table.
  * @hooked WC_Structured_Data::generate_order_data() Generates structured 
data.
  * @hooked WC_Structured_Data::output_structured_data() Outputs structured 
data.
   * @since 2.5.0
  */
 do_action( 'woocommerce_email_order_details', $order, $sent_to_admin, 
$plain_text, $email );

/**
  * @hooked WC_Emails::order_meta() Shows order meta data.
 */
 do_action( 'woocommerce_email_order_meta', $order, $sent_to_admin, 
  $plain_text, $email );

  /**
  * @hooked WC_Emails::customer_details() Shows customer details
  * @hooked WC_Emails::email_address() Shows email address
  */
 do_action( 'woocommerce_email_customer_details', $order, $sent_to_admin, 
 $plain_text, $email );

 /**
  * @hooked WC_Emails::email_footer() Output the email footer
 */
 do_action( 'woocommerce_email_footer', $email );

更新：如果需要在管理员“新订单”通知的页脚中添加，请使用以下命令：

add_action ('woocommerce_email_order_details', 'including_global_email_data', 2, 4 );
function including_global_email_data( $order, $sent_to_admin, $plain_text, $email ){
    // Set global email variable
    $GLOBALS['email_data'] = array( 'email' => $email, 'admin' => $sent_to_admin );
}

add_filter ('woocommerce_email_footer_text', 'custom_email_footer_text', 20, 1 );
function custom_email_footer_text( $footer_text ){
    // Get global variables
    $refNameGlobalsVar = $GLOBALS;
    $sent_to_admin = $refNameGlobalsVar['email_data']['admin'];
    $email         = $refNameGlobalsVar['email_data']['email'];

    // Only for admin "New order" email notification
    if( $email->id === 'new_order' ) // Or also:  if( $sent_to_admin )
    {
    $footer_text .= '<br><a href="http://maps.google.com/maps?q=nieuwstraat+15+brussel+1000+Belgium" class="m_8816063166882312894map-it-link" target="_blank" data-saferedirecturl="https://www.google.com/url?q=http://maps.google.com/maps?q%3Dnieuwstraat%2B15%2Bbrussel%2B1000%2BBelgium&amp">Map It</a>';
    }
    return $footer_text;
}

add_action（'woocommerce_email_order_details'，'include_global_email_data'，2,4）；
功能包括全局电子邮件数据（$order，$sent，$to，$admin，$plain，$email）{
//设置全局电子邮件变量
$GLOBALS['email\u data']=数组（'email'=>$email，'admin'=>$sent\u to\u admin）；
}
添加过滤器（'woocommerce\u email\u footer\u text'，'custom\u email\u footer\u text'，20,1）；
功能自定义\电子邮件\页脚\文本（$页脚\文本）{
//获取全局变量
$refnamelobalsvar=$GLOBALS；
$sent_to_admin=$refNameGlobalsVar['email_data']['admin']；
$email=$refNameGlobalsVar['email_data']['email']；
//仅适用于管理员“新订单”电子邮件通知
if（$email->id=='new\u order'）//或者：if（$sent\u to\u admin）
{
$footer_text.='
'；
}
返回$footer\u文本；
}

代码进入活动子主题（或活动主题）的function.php文件。经过测试，效果良好。
非常感谢，这对我已经有很大帮助了！但是我需要订单的账单地址信息来代替链接中的静态地址信息。“Nieuwstraat 15 Brussel 1000比利时”只是一个例子。
