在 Woocommerce 中向客户发送订单失败电子邮件通知

Question

我在我的主题 functions.php 文件中使用以下代码仅将订单失败的电子邮件发送给客户而不是管理员：

function wc_failed_order_email_to_customer( $recipient, $order ){
     return $recipient = $order->billing_email;
}
add_filter( 'woocommerce_email_recipient_failed_order', 'wc_failed_order_email_to_customer', 10, 2 );

而且它有效……

但我在 php 日志文件中收到以下错误：

Error: billing_email was called incorrectly. Order properties should not be accessed directly. Backtrace: require('wp-blog-header.php'), require_once('wp-includes/template-loader.php'), do_action('template_redirect'), WP_Hook->do_action, WP_Hook->apply_filters, WC_AJAX::do_wc_ajax, do_action('wc_ajax_checkout'), WP_Hook->do_action, WP_Hook->apply_filters, WC_AJAX::checkout, WC_Checkout->process_checkout, WC_Checkout->process_order_payment, WC_Braintree\Plugin_Framework\SV_WC_Payment_Gateway_Direct->process_payment, WC_Braintree\Plugin_Framework\SV_WC_Payment_Gateway_Direct->do_transaction, WC_Braintree\Plugin_Framework\SV_WC_Payment_Gateway->do_transaction_failed_result, WC_Braintree\Plugin_Framework\SV_WC_Payment_Gateway->mark_order_as_failed, WC_Order->update_status, WC_Order->save, WC_Order->status_transition, do_action('woocommerce_order_status_pending_to_failed'), WP_Hook->do_action, WP_Hook->apply_filters, WC_Emails::send_transactional_email, do_action_ref_array, WP_Hook->do_action, WP_Hook->apply_filters, WC_Email_Failed_Order->trigger, WC_Email->get_recipient, apply_filters('woocommerce_email_recipient_failed_order'), WP_Hook->apply_filters, wc_failed_order_email_to_customer, WC_Abstract_Legacy_Order->__get, wc_doing_it_wrong. This message was added in version 3.0.

我该如何解决这个错误？

Answer 1

您需要将billing_email 替换为WC_Order 方法get_billing_email() 之类的：

add_filter( 'woocommerce_email_recipient_failed_order', 'wc_failed_order_email_to_customer', 10, 2 );
function wc_failed_order_email_to_customer( $recipient, $order ){
     if( ! is_a( $order, 'WC_Order' ) ) 
         return $recipient;

     if( $billing_email = $order->get_billing_email() ) 
         $recipient = $billing_email;
     return $recipient;
}

代码进入您的活动子主题（或活动主题）的 function.php 文件中。经过测试并且可以工作。
