在新订单电子邮件通知中获取客户订单数 [英] Get customer order count in new order email notification

问题描述

如果是回头客，我想在 WooCommerce 的新订单"电子邮件通知中注明.

I'd like to indicate in WooCommerce "new order" email notification, if it's a repeat customer.

看起来很简单，但我尝试了大约 5 种不同的方法，但都没有奏效.我试过把它放到 2 个不同的钩子里:

It seems simple, but I've tried about 5 different methods and none worked. I've tried putting this into 2 different hooks:

• woocommerce_email_after_order_table
• woocommerce_email_subject_new_order.

似乎 wc_get_customer_order_count($user->ID) 应该可以工作，但看起来 $user> 对象没有传递到那些钩子的函数中，对吧?

Seems like wc_get_customer_order_count($user->ID) should work but it appears that the $user object is not passed into those hook's functions, right?

我还想知道，如果是访客而不是注册用户，是否可以通过比较电子邮件地址来实现这一点?

I'm also wondering if this is possible when it's a guest and not a registered user, maybe by comparing the email address?

谢谢

推荐答案

WooCommerce 电子邮件通知与订单相关.

在 woocommerce_email_after_order_table 钩子中，您将 Order 对象作为钩子自定义函数和 $email 对象中的参数.

In woocommerce_email_after_order_table hook, you have the Order object as an argument in your hooked custom function and also the $email object.

使用 $order 对象，您可以通过以下方式获取 user ID:

With that $order object, you can get the user ID this way:

$user_id = $user_id = $order->get_user_id();

您可以从 $email 对象中定位新订单电子邮件通知.

From the $email object you can target the new order email notification.

所以工作代码将是:

add_action( 'woocommerce_email_after_order_table', 'customer_order_count', 10, 4);
function customer_order_count( $order, $sent_to_admin, $plain_text, $email ){

    if ( $order->get_user_id() > 0 ){

        // Targetting new orders (that will be sent to customer and to shop manager)
        if ( 'new_order' == $email->id ){

            // Getting the user ID
            $user_id = $order->get_user_id();

            // Get the user order count
            $order_count = wc_get_customer_order_count( $user_id );

            // Display the user order count
            echo '<p>Customer order count: '.$order_count.'</p>';

        }
    }
}

例如，您也可以使用 woocommerce_email_before_order_table 钩子来代替...

You can also use instead the woocommerce_email_before_order_table hook for example…

代码位于活动子主题(或主题)的 function.php 文件或任何插件文件中.

此代码已经过测试且有效.

This code is tested and works.
