我想将续订订单电子邮件发送到辅助用户电子邮件（我已使用 ACF 在用户编辑页面中添加）。
我尝试了很多方法，woocommerce_subscription_payment_complete 也不适合我。
我尝试过以下代码：
add_action( 'woocommerce_order_status_completed', 'action_on_order_status_completed', 20, 2 );
function action_on_order_status_completed( $order_id, $order ){
$order = new WC_Order($order_id);
// Get the user ID from WC_Order methods
$user_id = $order->get_user_id(); // or $order->get_customer_id();
$secondary_recipient = get_field('secondary_email', 'user_'.$user_id );
$subscriptions_ids = wcs_get_subscriptions_for_order( $order_id, array( 'order_type' => 'any' ) );
// We get all related subscriptions for this order
foreach( $subscriptions_ids as $subscription_id => $subscription_obj )
if($subscription_obj->order->id == $order_id) break; // Stop the loop
// $subscription_objc = wcs_get_subscription($subscription_id);
//$userid = $subscription_objc->get_user_id();
$wc_emails = WC()->mailer()->get_emails();
$wc_emails['WCS_Email_Processing_Renewal_Order']->recipient = $secondary_recipient;
$wc_emails['WCS_Email_Processing_Renewal_Order']->trigger($subscription_id);
// $to = $secondary_recipient;
// $subject = "hi";
// $body =$user_id."end".$order_id."hhh".$subscription_id;
// $headers = array('Content-Type: text/html; charset=UTF-8');
// //$headers[] = 'Cc: sarun@cloudspring.in';
// wp_mail( $to, $subject, $body, $headers );
}仅供参考：如果我使用带注释的 wp_mail 功能，则会发送电子邮件。

我们可以添加一个辅助电子邮件作为收件人，尝试下面的代码测试并且它有效。
add_filter( 'woocommerce_email_recipient_customer_completed_renewal_order', 'my_email_recipient_filter_function', 10, 2);
function my_email_recipient_filter_function( $recipient, $order ) {
$user_id = $order->get_user_id(); // or $order->get_customer_id();
$secondary_recipient = get_field('secondary_email', 'user_'.$user_id );
if(! empty($secondary_recipient)){
$recipient = $recipient . ', '. $secondary_recipient;
return $recipient;
}else {
return $recipient;
}
}
