Question

在Woocommerce API中，我看到了一个方法wc_get_orders

在上面提到的参数中，我没有看到一个论据，我可以提供产品ID或对象来限制特定产品的订单结果。

我是否有办法过滤特定产品的订单？

我需要使用这种方法，因为有些参数是必要的

Answer 1

<强>被修改此功能不存在，但可以构建。因此，下面的函数将返回给定产品ID的所有订单ID的数组，从而生成正确的SQL查询：

/**
 * Get All orders IDs for a given product ID.
 *
 * @param  integer  $product_id (required)
 * @param  array    $order_status (optional) Default is 'wc-completed'
 *
 * @return array
 */
function get_orders_ids_by_product_id( $product_id, $order_status = array( 'wc-completed' ) ){
    global $wpdb;

    $results = $wpdb->get_col("
        SELECT order_items.order_id
        FROM {$wpdb->prefix}woocommerce_order_items as order_items
        LEFT JOIN {$wpdb->prefix}woocommerce_order_itemmeta as order_item_meta ON order_items.order_item_id = order_item_meta.order_item_id
        LEFT JOIN {$wpdb->posts} AS posts ON order_items.order_id = posts.ID
        WHERE posts.post_type = 'shop_order'
        AND posts.post_status IN ( '" . implode( "','", $order_status ) . "' )
        AND order_items.order_item_type = 'line_item'
        AND order_item_meta.meta_key = '_product_id'
        AND order_item_meta.meta_value = '$product_id'
    ");

    return $results;
}

USAGE 1 （对于给定的商品ID 37 和默认的已完成订单状态）：

$orders_ids = get_orders_ids_by_product_id( 37 );

// The output (for testing)
print_r( $orders_ids );

USAGE 2 （对于给定的商品ID 37 和某些已定义的订单状态）：

// Set the orders statuses
$statuses = array( 'wc-completed', 'wc-processing', 'wc-on-hold' );

$orders_ids = get_orders_ids_by_product_id( 37, $statuses );

// The output (for testing)
print_r( $orders_ids );

代码放在活动子主题（或主题）的function.php文件中，或者放在任何插件文件中。

此代码经过测试并有效。

所以我想获取特定于产品和人的订单。我使用@LoicTheActec提供的解决方案和wc_get_orders woocommerce方法来获得我想要的结果。

以下是功能：

    /**
 * Get All orders IDs for a given product ID.
 *
 * @param  integer  $product_id (required)
 * @param  array    $order_status (optional) Default is 'wc-completed'
 *
 * @return array
 */
public function get_orders_ids_by_product_id( $product_id, $order_status = array( 'wc-completed' ) ) {
    global $wpdb;

    $results = $wpdb->get_col("
        SELECT order_items.order_id
        FROM {$wpdb->prefix}woocommerce_order_items as order_items
        LEFT JOIN {$wpdb->prefix}woocommerce_order_itemmeta as order_item_meta ON order_items.order_item_id = order_item_meta.order_item_id
        LEFT JOIN {$wpdb->posts} AS posts ON order_items.order_id = posts.ID
        WHERE posts.post_type = 'shop_order'
        AND posts.post_status IN ( '" . implode( "','", $order_status ) . "' )
        AND order_items.order_item_type = 'line_item'
        AND order_item_meta.meta_key = '_product_id'
        AND order_item_meta.meta_value = '$product_id'
    ");

    return $results;
}

过滤掉我想要的结果。由于该方法不提供include参数，因此我必须获取所有订单，然后删除给定产品ID的订单并从wc_get_orders中排除所有剩余的订单：

    /**
 * Check if current user has more than 3 orders
 *
 * @return void
 * @author 
 **/
public function woocommerce_check_order_count($product_id, $customer_email)
{   


    $statuses = array(  'wc-processing' );

    $orders_ids_for_product = $this->get_orders_ids_by_product_id( $product_id, $statuses );


    // Get All Orders
    $allorders = wc_get_orders( array(
        'status'      => 'processing',
        'type'        => 'shop_order',
        'email'       => '',
        'limit'       => -1,
        'return'      => 'ids',
    ) );

    // Remove the $orders_ids_for_product array from the $allorders array
    $orderstoexclude = array_diff($allorders, $orders_ids_for_product);

    $orders = wc_get_orders( array(
        'status'      => 'processing',
        'type'        => 'shop_order',
        'customer'    => $customer_email,
        'email'       => '',
        'limit'       => 3,
        'exclude'     => $orderstoexclude,
        'return'      => 'ids',
    ) );

    return $orders;

}
