从 Woocommerce 中购买的产品 ID 获取最后一个订单 ID

Question

如果客户购买了产品，如何获取特定产品的订单号？我尝试了下面的代码但没有用。提前感谢您的帮助。

<?php
 $order = new wc_get_order( $order_id );
 $order->get_id();
 echo $order->get_order_number();
?>

也试过此代码但没有用。

$product_ids = array(37,53);
$order_ids = get_order_ids_from_bought_items( $product_ids );

Answer 1

function get_order_ids_from_bought_items() {

    $prod_arr = array('37', '53');
    $purchased = false;

    $customer_orders = get_posts(array(
        'numberposts' => -1,
        'post_type' => 'shop_order',
        'meta_key' => '_customer_user',
        'meta_value' => get_current_user_id(),
            ));
    foreach ($customer_orders as $order_post) {


        $order = wc_get_order($order_post->ID);

        foreach ($order->get_items() as $item) {

            $product_id = $item->get_product_id();

            if (in_array($product_id, $prod_arr))
                $purchased = true;
        }
    }

    return $purchased; // $order_post->ID  for Order ID
}

以下函数使用一个非常轻量级的 SQL 查询，它将 return 来自给定客户的定义产品 ID 的最后一个订单 ID：

function get_last_order_id_from_product( $product_id, $user_id = 0 ) {
    global $wpdb;

    $customer_id = $user_id == 0 ? get_current_user_id() : $user_id;

    return $wpdb->get_var( "
        SELECT p.ID FROM {$wpdb->prefix}posts AS p
        INNER JOIN {$wpdb->prefix}postmeta AS pm ON p.ID = pm.post_id
        INNER JOIN {$wpdb->prefix}woocommerce_order_items AS woi ON p.ID = woi.order_id
        INNER JOIN {$wpdb->prefix}woocommerce_order_itemmeta AS woim ON woi.order_item_id = woim.order_item_id
        WHERE p.post_type = 'shop_order'
        AND pm.meta_key = '_customer_user'
        AND pm.meta_value = $customer_id
        AND woim.meta_key IN ( '_product_id', '_variation_id' )
        AND woim.meta_value = $product_id
        ORDER BY p.ID DESC  LIMIT 1
    " );
}

代码在您的活动子主题（或活动主题）的 function.php 文件中继续。已测试并有效。

If the customer has not purchased the product yet the function will return false.

用法示例：

您将在下面设置产品 ID 37 和可选的用户 ID 153(如果你不用前端代码，函数可以获取当前用户Id)*/

$order_id = get_last_order_id_from_product( 37, 153 );

或当前用户：

$order_id = get_last_order_id_from_product( 37 );
