将自定义用户电子邮件添加到 CC 以获取特定的 Woocommerce 电子邮件通知 [英] Add custom user email to CC for specific Woocommerce email notification

问题描述

在 Woocommerce 中，我尝试自定义代码 从此线程在客户完成的订单电子邮件通知中添加自定义电子邮件作为抄送"电子邮件地址:

In Woocommerce I try to customize the code from this thread to add a custom email as "CC" email address in customer completed order email notification:

/**
 * Function adds a BCC header to emails that match our array
 * 
 * @param string $headers The default headers being used
 * @param string $object  The email type/object that is being processed
 */
    function add_cc_to_certain_emails( $headers, $object ) {
    // email types/objects to add cc to
    $cc_email = get_user_meta( $user_id, 'order_cc_email', true ); // MY CUSTOM CODE
    $add_cc_to = array(
        'customer_completed_order', // Customer Processing order from WooCommerce
    );
    // if our email object is in our array
    if ( in_array( $object, $add_cc_to ) ) {
        // change our headers
        $headers = array( 
            $headers,
//          'Cc: Me <[e-mail]>' ."
", // INITIAL CODE
            'Cc: '.$cc_email.' <'.$cc_email.'>' ."
", // MY CUSTOM CODE
    }
    return $headers;
}
add_filter( 'woocommerce_email_headers', 'add_cc_to_certain_emails', 10, 2 );

我找不到从用户元数据中获取自定义用户电子邮件的方法，因此我的代码无法按预期工作.

I can't find the way to get custom user email from user meta data, and so my code doesn't work as expected.

如何从用户元数据中获取自定义用户电子邮件?

How to get the custom user email from user meta data?

如何在电子邮件标题中将此电子邮件(带有客户全名)添加为CC"?

How to add this email (with the customer full name) as "CC" in email header?

推荐答案

您的钩子函数中缺少一些参数，因为 woocommerce_email_headers 过滤器钩子允许 3 个参数:

There is some missing arguments in your hooked function, as woocommerce_email_headers filter hook allow 3 arguments:

• $header ===> 过滤器返回的头部数据
• $email_id==> 当前 WC_Email ID (但不是 $object...)
• $order ====> WC_Order 对象的实例(缺少的有用的)

• $header ===> the header data to be return in this filter
• $email_id==> the current WC_Email ID (but not the $object…)
• $order ====> the instance of the WC_Order object (the missing useful one)

试试这个重新访问的代码:

Try this revisited code instead:

add_filter( 'woocommerce_email_headers', 'custom_cc_email_headers', 10, 3 );
function custom_cc_email_headers( $header, $email_id, $order ) {

    // Only for "Customer Completed Order" email notification
    if( 'customer_completed_order' !== $email_id )
        return $header;

    // Get the custom email from user meta data  (with the correct User ID)
    $custom_user_email = get_user_meta( $order->get_user_id(), 'order_cc_email', true );

    if( ! empty($custom_email) ) 
        return $header; // Exit (if empty value)

    // Get customer billing full name
    $user_name  = $order->get_billing_first_name().' ';
    $user_name .= $order->get_billing_last_name();

    // Merge and prepare the data
    $formatted_email = utf8_decode($user_name . ' <' . $custom_user_email . '>');

    // Add Cc to headers
    $header .= 'Cc: '.$formatted_email .'
';

    return $header;
}

代码位于活动子主题(或活动主题)的 function.php 文件中.经过测试和工作.

Code goes in function.php file of your active child theme (or active theme). Tested and work.
