为WooCommerce CSV导出插件添加自定义字段-对于客户第一订单

问题描述

我正在使用 Woocommerce CSV导出插件.我希望有一种方法可以检查客户是否是新客户，如果是新客户，可以为自定义meta-key 和 true值写入订单元数据.
但是，如果用户不是New，则什么也不会发生.

I'm using Woocommerce CSV Export plugin. I will like to have a way to check if the customer is NEW and if it is, to write in order metadata for a custom meta-key a true value.
But if user is not New, nothing will happen.

我首先想到的是WP用户(user_registered)的创建日期.但是我认为有更好，更快的方法.换句话说，我怎么知道这是否是客户的第一订单...

I thought first to start with the creation date of the WP user (user_registered). But I think there is a better and faster way. In other words, how can I know if this is the first order of a client...

我的目标:如果该客户是第一次订购，请在导出CSV"中为该订单提供一个 TRUE 值.

My goal: If this customer is ordering for the first time, have a TRUE value, for this order in the Export CSV.

然后我尝试了使用此答案代码没有成功.

Then I have tried to use this answer code without success.

我的问题:
我怎么能做到这一点?

My question:
How could I achieve this?

谢谢

推荐答案

基于 (我最近做了)，有可能会添加一个元键/ wp_postmeta 数据库中表中的新客户优先订单"值.因此，我们将以这种方式更改该条件函数:

Based on this answer code (I have recently made), it's possible to have a function that will add a meta key/value in the database wp_postmeta table for a New customer first order. So we will change a bit that conditional function this way:

function new_customer_has_bought() {

    $count = 0;
    $new_customer = false;

    // Get all customer orders
    $customer_orders = get_posts( array(
        'numberposts' => -1,
        'meta_key'    => '_customer_user',
        'meta_value'  => get_current_user_id()
    ) );

    // Going through each current customer orders
    foreach ( $customer_orders as $customer_order ) {
        $count++;
    }

    // return "true" when it is the first order for this customer
    if ( $count > 2 ) // or ( $count == 1 )
        $new_customer = true;

    return $new_customer;
}

此代码在您的活动子主题或主题的function.php文件中，或在插件php文件中.

在THANKYOU HOOK中的用法:

add_action( 'woocommerce_thankyou', 'tracking_new_customer' );
function tracking_new_customer( $order_id ) {

    // Exit if no Order  ID
    if ( ! $order_id ) {
        return;
    }

    // The paid orders are changed to "completed" status
    $order = wc_get_order( $order_id );
    $order->update_status( 'completed' );

    // For 1st 'completed' costumer paid order status
    if ( new_customer_has_bought() && $order->has_status( 'completed' ) ) 
    { 
        // Create 'first_order' custom field with 'true' value
        update_post_meta( $order_id, 'first_order', 'true' ); needed)
    }
    else  // For all other customer paid orders
    {
        // udpdate existing  'first_order' CF to '' value (empty)
        update_post_meta( $order_id, 'first_order', '' );
    }
}

此代码在您的活动子主题或主题的function.php文件中，或在插件php文件中.

要为已定义的订单ID获得此值，您将使用此参数(最后一个参数表示它是一个字符串):

To get this this value for a defined order ID, you will use this (last argument means it's a string):

// Getting the value for a defined $order_id
$first_customer_order = get_post_meta( $order_id, 'first_order', false );

// to display it
echo $first_customer_order;

所有代码均已通过测试并且可以正常工作.

参考

• 模板结构+通过主题覆盖模板
• 检查客户是否已经购买了商品在WooCommerce中
• 检查如果客户早些时候在WooCommerce中购买了特定产品
• WP代码参考-update_post_meta()函数
• WP代码参考-get_post_meta()函数

• Template Structure + Overriding Templates via a Theme
• Checking if customer has already bought something in WooCommerce
• Check if a customer has purchased a specific product earlier in WooCommerce
• WP Code Reference - update_post_meta() function
• WP Code Reference - get_post_meta() function
