在新订单Woocommerce电子邮件通知中添加自定义链接

Question

我正在建立一个餐厅网站。 在该网站的早期版本中，在餐厅有人需要送货时收到的邮件中，我有一个指向Google地图的链接。 餐厅很容易使用它来导航到餐厅的客户。 现在，我更改站点，将使用woocommerce，但我也希望在管理邮件中链接到Google Maps。

来自旧站点的代码。 （带有指向Google Map的链接的超链接，名为“ Map It”。）

<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>

为此，在woocommerce中，我需要更改woocommerce admin-new-order的模板，以在地址下方添加超链接，但是我不知道该怎么做。

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 );

我怎样才能解决这个问题？

编辑：谷歌地图的超链接应该基于woocommerce订单的账单地址，而不是硬编码的示例：Nieuwstrat 15 Brussel

基于LoicTheAztec的出色回答，我使用了略作修改的方法：

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' => 
$sent_to_admin,'order' =>$order );
}

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'];
    $order         = $refNameGlobalsVar['email_data']['order'];

    // Only for admin "New order" email notification
    if( $email->id === 'new_order' ) // Or also:  if( $sent_to_admin )
    {
    $urltemp.=$order->billing_address_1.' '.$order->billing_address_2.' 
'.$order->billing_city.' '.$order->billing_postcode.' '.$order- 
    >billing_country;
    $urltemp=str_replace(" ","+",$urltemp);
    $urltemp='http://maps.google.com/maps?q='.$urltemp;
    $footer_text.='<br><a href="'.$urltemp.'" 
class="m_8816063166882312894map-it-link" target="_blank" data- 
   saferedirecturl="'.$urltemp.'&amp">Map It</a>';
    }
    return $footer_text;
}

更新：如果您需要在页脚中添加管理员“新订单”通知，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;
}

代码进入您的活动子主题（或活动主题）的function.php文件中。 经过测试和工作。
