Woocommerce 预订 - 将预订确认电子邮件发送到自定义字段值答案

【问题描述】：

我正在尝试连接到“woocommerce_email_recipient_booking_confirmed”以更新/添加到收件人字段。下面的链接非常适用于默认的 WooCommerce 电子邮件（及其操作）。如果我在操作中手动输入电子邮件，则该操作有效，但我需要来自客户输入的电子邮件（通过产品页面上的自定义字段）。

我相信这与 class-wc-email-booking-confirmed.php 有关。当我将它与 class-wc-email-customer-completed-order.php 进行比较时

class-wc-email-booking-confirmed.php

public function trigger( $booking_id )

class-wc-email-customer-completed-order.php

public function trigger( $order_id, $order = false )

我的代码（我没有从下面的资源中更改）：

add_filter( 'woocommerce_email_recipient_booking_confirmed', 'additional_customer_email_recipient', 9999, 2 ); // Completed Order

function additional_customer_email_recipient( $recipient, $order ) {

  if ( ! is_a( $order, 'WC_Order' ) ) return $recipient;  // when I comment this out, an ajax error is thrown. This is why I believe the order object directly accessible yet.

    $additional_recipients = array(); // Initializing…

    foreach( $order->get_items() as $item_id => $item_data ){
        $email = wc_get_order_item_meta( $item_id, 'Email Address', true );

        if( ! in_array( $email, $additional_recipients ) && strpos( $recipient, $email ) === false )
            $additional_recipients[] = $email;
    }

    $additional_recipients = implode( ',', $additional_recipients);

    if( count($additional_recipients) > 0)
    {
        $recipient = ','.$additional_recipients;
    }
    return $recipient;
}

【解决方案1】：

因为它不是订单对象，我只需要调用 get_order()。

$order = $order->get_order();

代码：

add_filter( 'woocommerce_email_recipient_booking_confirmed', 'additional_customer_email_recipient', 10, 2 );

function additional_customer_email_recipient( $recipient, $order ) {

    $order = $order->get_order();

    $additional_recipients = array(); 

    foreach( $order->get_items() as $item_id => $item_data ){
        $email = wc_get_order_item_meta( $item_id, 'Email Address', true );

        if( ! in_array( $email, $additional_recipients ) && strpos( $recipient, $email ) === false )

            $additional_recipients[] = $email;
    }

    $additional_recipients = implode( ',', $additional_recipients);

    if( count($additional_recipients) > 0)
    {
        $recipient = $additional_recipients;
    }
    return $recipient;
}
