自定义消息取决于用户购买的所有金额的总和

Question

为了改进这段代码，我想让它工作，这取决于用户在此之前所做的所有购买的总和。也就是说，如果整个数量小于<100欧元，请发送电子邮件，如果价格>在100欧元-200欧元之间，则发送另一封电子邮件，如果超过200欧元，则发送另一封电子邮件。

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 ( $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>';
}

我怎样才能实现它？

提前谢谢。

你可以尝试这样的事情：

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);
    $user_total_calculated = 0;
    // Get all current customer orders
    $customer_orders = wc_get_orders( $args = array(
        'numberposts' => -1,
        'meta_key'    => '_customer_user',
        'meta_value'  => $order->customer_user,
        'post_status' => 'wc_completed'
    ) );
    // Iterating and summing all paid current customer orders
    foreach ( $customer_orders as $customer_order )
        $user_total_calculated += get_post_meta($customer_order->ID, '_order_total', true);
    // After this you can now set your 3 conditions displaying 3 different notices or custom message
    if ( $order->post_status == 'wc-completed' && in_array('customer', $user_data->roles) ){
        if (100 >= $user_total_calculated)
            echo '<h2 id="h2thanks">Get 5% off</h2><p id="pthanks">Thank you for making this purchase! Come back and use the code "<strong>Back4More5</strong>" to receive a 5% discount on your next purchase! Click here to continue shopping.</p>';
        elseif ( 100 < $user_total_calculated && 200 >= $user_total_calculated )
            echo '<h2 id="h2thanks">Get 10% off</h2><p id="pthanks">Thank you for making this purchase! Come back and use the code "<strong>Back4More10</strong>" to receive a 10% discount on your next purchase! Click here to continue shopping.</p>';
        elseif ( 200 < $user_total_calculated )
            echo '<h2 id="h2thanks">Get 20% off</h2><p id="pthanks">Thank you for making this purchase! Come back and use the code "<strong>Back4More20</strong>" to receive a 20% discount on your next purchase! Click here to continue shopping.</p>';
    }
}

此代码应该有效

代码进入函数.php活动子主题的文件（活动主题或任何插件文件）。
