WooCommerce-在一段时间内按用户获取完成的状态订单

可以获取当前客户在过去30天内购买的商品总数。

这是基于此答案的此功能的代码：

function current_customer_month_count( $user_id=null ) {
    if ( empty($user_id) ){
        $user_id = get_current_user_id();
    }
    // Date calculations to limit the query
    $today_year = date( 'Y' );
    $today_month = date( 'm' );
    $day = date( 'd' );
    if ($today_month == '01') {
        $month = '12';
        $year = $today_year - 1;
    } else{
        $month = $today_month - 1;
        $month = sprintf("%02d", $month);
        $year = $today_year - 1;
    }

    // ORDERS FOR LAST 30 DAYS (Time calculations)
    $now = strtotime('now');
    // Set the gap time (here 30 days)
    $gap_days = 30;
    $gap_days_in_seconds = 60*60*24*$gap_days;
    $gap_time = $now - $gap_days_in_seconds;

    // The query arguments
    $args = array(
        // WC orders post type
        'post_type'   => 'shop_order',
        // Only orders with status "completed" (others common status: 'wc-on-hold' or 'wc-processing')
        'post_status' => 'wc-completed', 
        // all posts
        'numberposts' => -1,
        // for current user id
        'meta_key'    => '_customer_user',
        'meta_value'  => $user_id,
        'date_query' => array(
            //orders published on last 30 days
            'relation' => 'OR',
            array(
                'year' => $today_year,
                'month' => $today_month,
            ),
            array(
                'year' => $year,
                'month' => $month,
            ),
        ),
    );

    // Get all customer orders
    $customer_orders = get_posts( $args );
    $count = 0;
    if (!empty($customer_orders)) {
        $customer_orders_date = array();
        // Going through each current customer orders
        foreach ( $customer_orders as $customer_order ){
            // Conveting order dates in seconds
            $customer_order_date = strtotime($customer_order->post_date);
            // Only past 30 days orders
            if ( $customer_order_date > $gap_time ) {
                $customer_order_date;
                $order = new WC_Order( $customer_order->ID );
                $order_items = $order->get_items();
                // Going through each current customer items in the order
                foreach ( $order_items as $order_item ){
                    $count++;
                }
            }
        }
        return $count;
    }
}

这段代码会出现在您活动的子主题（或主题）的function.php文件中，也可能出现在任何插件文件中。

该函数接受可选user_id参数（如果需要）。例如，对于一个user_idwith56值，您将通过以下方式使用该函数：

// For user ID: "56".
$number_of_items_in_last_month = current_customer_month_count('56');

该函数将当前用户的ID中$user_id = get_current_user_id();，如果你不设置一个参数user_id值时，这样说：

// For current logged user.
$number_of_items_in_last_month = current_customer_month_count();

您可以在条件if语句中使用此功能，以通过somme WooCommerce挂钩或相关模板隐藏或替换购物车按钮。
您可以在该任务中获得帮助，询问包括该代码的新问题，并提供有关如何执行此操作的更多详细信息。

此代码已经过测试并且可以工作。
