Question

我正在尝试在订单取消时向客户发送电子邮件。默认情况下，woocommerce仅将此电子邮件仅发送给网站的管理员。此代码解决了网络上相关帖子的问题：

function wc_cancelled_order_add_customer_email( $recipient, $order ){
   return $recipient . ',' . $order->billing_email;
}
add_filter( 'woocommerce_email_recipient_cancelled_order', 'wc_cancelled_order_add_customer_email', 10, 2 );
add_filter( 'woocommerce_email_recipient_failed_order', 'wc_cancelled_order_add_customer_email', 10, 2 );

但是，似乎woocommerce完全删除了那些过滤器挂钩。有没有办法做到这一点？

提前致谢！

在这个隐藏在 woocommerce_order_status_changed 操作挂钩中的自定义函数中，我定位＆＃34;取消＆＃34;并且＆＃34;失败＆＃34;订单向客户发送相应的电子邮件通知（管理员将通过WooCommerce自动通知接收它）：

add_action('woocommerce_order_status_changed', 'send_custom_email_notifications', 10, 4 );
function send_custom_email_notifications( $order_id, $old_status, $new_status, $order ){
    if ( $new_status == 'cancelled' || $new_status == 'failed' ){
        $wc_emails = WC()->mailer()->get_emails(); // Get all WC_emails objects instances
        $customer_email = $order->get_billing_email(); // The customer email
    }

    if ( $new_status == 'cancelled' ) {
        // change the recipient of this instance
        $wc_emails['WC_Email_Cancelled_Order']->recipient = $customer_email;
        // Sending the email from this instance
        $wc_emails['WC_Email_Cancelled_Order']->trigger( $order_id );
    } 
    elseif ( $new_status == 'failed' ) {
        // change the recipient of this instance
        $wc_emails['WC_Email_Failed_Order']->recipient = $customer_email;
        // Sending the email from this instance
        $wc_emails['WC_Email_Failed_Order']->trigger( $order_id );
    } 
}

代码放在活动子主题（或主题）的function.php文件中，或者放在任何插件文件中。

这应该适用于WooCommerce 3 +

如果您需要，而不是更改电子邮件，您可以将其添加到现有收件人：
// Add a recipient in this instance
$wc_emails['WC_Email_Failed_Order']->recipient .= ',' . $customer_email;
