停止$0价值产品的WooCommerce订阅管理员续订通知

Question

我发现了以下插件，当续订价值为0美元的订阅时，它会停止向客户发送通知。这对客户来说工作得很好，但管理员仍然会收到通知。是否有可能修改代码，以消除发送续订电子邮件给管理员？

感谢您的帮助

这些是WooCommerce订阅中使用的以下电子邮件类。

$email_classes['WCS_Email_New_Renewal_Order']              = new WCS_Email_New_Renewal_Order();
$email_classes['WCS_Email_New_Switch_Order']               = new WCS_Email_New_Switch_Order();
$email_classes['WCS_Email_Processing_Renewal_Order']       = new WCS_Email_Processing_Renewal_Order();
$email_classes['WCS_Email_Completed_Renewal_Order']        = new WCS_Email_Completed_Renewal_Order();
$email_classes['WCS_Email_Customer_On_Hold_Renewal_Order'] = new WCS_Email_Customer_On_Hold_Renewal_Order();
$email_classes['WCS_Email_Completed_Switch_Order']         = new WCS_Email_Completed_Switch_Order();
$email_classes['WCS_Email_Customer_Renewal_Invoice']       = new WCS_Email_Customer_Renewal_Invoice();
$email_classes['WCS_Email_Cancelled_Subscription']         = new WCS_Email_Cancelled_Subscription();
$email_classes['WCS_Email_Expired_Subscription']           = new WCS_Email_Expired_Subscription();
$email_classes['WCS_Email_On_Hold_Subscription']           = new WCS_Email_On_Hold_Subscription();

WCS_Email_New_Switch_Order和WCS_Email_New_Switch_Order这是唯一向管理员发送电子邮件的类。

下面是在WCS_Email_New_Switch_Order和WCS_Email_New_Switch_Order中用来发送电子邮件的操作。

'woocommerce_order_status_pending_to_processing_renewal_notification'
'woocommerce_order_status_pending_to_completed_renewal_notification'
'woocommerce_order_status_pending_to_on-hold_renewal_notification'
'woocommerce_order_status_failed_to_processing_renewal_notification'
'woocommerce_order_status_failed_to_completed_renewal_notification'
'woocommerce_order_status_failed_to_on-hold_renewal_notification'
'woocommerce_order_status_cancelled_to_processing_renewal_notification'
'woocommerce_order_status_cancelled_to_completed_renewal_notification'
'woocommerce_order_status_cancelled_to_on-hold_renewal_notification'
'woocommerce_subscriptions_switch_completed_switch_notification'

因此，您还必须使用回调函数eg_maybe_remove_email添加上述操作。检查下面的代码。

<?php
/*
Plugin Name: WooCommerce Subscriptions No $0 Emails
Plugin URI:
Description: Do not send a processing or completed renewal order emails to customers when the order or renewal is for $0.00.

*/

function eg_maybe_remove_email( $order_id ){

    $order = new WC_Order( $order_id );

    if ( 0 == $order->get_total() ) {

        $email_class = array();
        
        switch( current_filter() ) {
            case 'woocommerce_order_status_completed_renewal_notification':
                $email_class[] = 'WCS_Email_Completed_Renewal_Order';
                break;
            case 'woocommerce_order_status_pending_to_processing_renewal_notification':
                $email_class[] = 'WCS_Email_Processing_Renewal_Order';
                $email_class[] = 'WCS_Email_New_Renewal_Order';
                break;
            case 'woocommerce_order_status_failed_renewal_notification':
                $email_class[] = 'WCS_Email_Customer_Renewal_Invoice';
                $email_class[] = 'WCS_Email_New_Renewal_Order';
                break;
            case 'woocommerce_order_status_pending_to_completed_renewal_notification':
            case 'woocommerce_order_status_pending_to_on-hold_renewal_notification':
            case 'woocommerce_order_status_failed_to_processing_renewal_notification':
            case 'woocommerce_order_status_failed_to_completed_renewal_notification':
            case 'woocommerce_order_status_failed_to_on-hold_renewal_notification':
            case 'woocommerce_order_status_cancelled_to_processing_renewal_notification':
            case 'woocommerce_order_status_cancelled_to_completed_renewal_notification':
            case 'woocommerce_order_status_cancelled_to_on-hold_renewal_notification':
                $email_class[] = 'WCS_Email_New_Renewal_Order';
                break;
            case 'woocommerce_subscriptions_switch_completed_switch_notification':
                $email_class[] = 'WCS_Email_New_Switch_Order';
                break;
            default:
                $email_class[] = array();
                break;
        }

        if ( ! empty( $email_class ) ) {
            foreach ( $email_class  as $key => $email ) {
                remove_action( current_filter(), array( WC()->mailer()->emails[ $email ], 'trigger' ) );
            }
        }

    }
