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。在该网站的先前版本中，当有人想要送货时，在餐厅收到的邮件中，我有一个指向谷歌地图的链接。餐厅很容易使用它来导航到餐厅的客户。 现在我更改了网站，我将与woocommerce合作，但我还希望在管理员邮件中包含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"。

<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>

要在woocommerce中执行此操作，我需要更改woocommerce管理员新订单的模板，在地址下方添加超链接，但我不知道该怎么做。

模板管理员新订单.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 );

我该如何解决这个问题？

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

布鲁塞尔根据LoicTheAztec的出色回答，我使用了略微调整：

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：如果您需要在管理员"新订单"通知的页脚中添加它，请使用以下内容：

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;
}

代码进入函数.php活动子主题(或活动主题(的文件。经过测试并工作。
