php - Custom message on completed order status email notification only for customer user role

Question

I would like to improve this code from this answer, to display a message on completed order status emails only for customers, but not for other user roles (as subscribers, etc...).

Here is that code:

add_action( 'woocommerce_email_before_order_table', 'completed_order_mail_message', 20 );
function completed_order_mail_message( $order ) {
    if ( empty( $order->get_used_coupons() ) && $order->post_status == 'wc-completed' )
        echo '<h2 id="h2thanks">Get 20% off</h2><p id="pthanks">Thank you for making this purchase! Come back and use the code "<strong>Back4More</strong>" to receive a 20% discount on your next purchase! Click here to continue shopping.</p>';
}

How can I achieve it?

Thanks

要在电子邮件通知上启用此自定义消息以获取完整的订单状态并且仅针对“客户”用户角色，您必须获取与订单相关的用户数据，以获取用户角色。然后你将在你的条件中使用它。

这是代码：

add_action( 'woocommerce_email_before_order_table', 'completed_order_mail_message', 20 );
function completed_order_mail_message( $order ) {

    // Getting order user data to get the user roles
    $user_data = get_userdata($order->customer_user);

    if ( empty( $order->get_used_coupons() ) && $order->post_status == 'wc-completed' && in_array('customer', $user_data->roles) )
        echo '<h2 id="h2thanks">Get 20% off</h2><p id="pthanks">Thank you for making this purchase! Come back and use the code "<strong>Back4More</strong>" to receive a 20% discount on your next purchase! Click here to continue shopping.</p>';
}

此代码位于您的活动子主题（或主题）的 function.php 文件中或任何插件文件中。

此代码经过测试并且功能齐全。
