如何按产品 ID 获取包含订单 ID 的数组？
我的意思是接收所有展示特定产品的订单。
我知道如何通过 MySQL 做到这一点，但是有没有办法通过 WP_Query 函数做到这一点？
【问题讨论】：
plugins\woocommerce\includes\admin\reports\class-wc-report-sales-by-product.php 文件，您必须为此编写 MySQL 查询，WooCommerce 本身使用 MySQL 查询。所以你必须使用@LoicTheAztec 答案。

更新：
2017 - SQL 查询更改为
"SELECT DISTINCT"而不是"SELECT"以避免 数组中的重复 订单 ID（则不需要array_unique()来过滤重复...）。2019 - 在 SQL 查询中启用产品变体类型支持
然后您可以将其嵌入到自定义函数中，并以 $product_id 作为参数。
您必须在其中设置您的订单状态定位。
下面是可以完成这项工作的函数：
function get_orders_ids_by_product_id( $product_id ) {
global $wpdb;
// Define HERE the orders status to include in <== <== <== <== <== <== <==
$orders_statuses = "'wc-completed', 'wc-processing', 'wc-on-hold'";
# Get All defined statuses Orders IDs for a defined product ID (or variation ID)
return $wpdb->get_col( "
SELECT DISTINCT woi.order_id
FROM {$wpdb->prefix}woocommerce_order_itemmeta as woim,
{$wpdb->prefix}woocommerce_order_items as woi,
{$wpdb->prefix}posts as p
WHERE woi.order_item_id = woim.order_item_id
AND woi.order_id = p.ID
AND p.post_status IN ( $orders_statuses )
AND woim.meta_key IN ( '_product_id', '_variation_id' )
AND woim.meta_value LIKE '$product_id'
ORDER BY woi.order_item_id DESC"
);
}
这段代码可以放在任何 php 文件中。
此代码经过测试，适用于 WooCommerce 版本 2.5+、2.6+ 和 3+
使用示例：
## This will display all orders containing this product ID in a coma separated string ##
// A defined product ID: 40
$product_id = 40;
// We get all the Orders for the given product ID in an arrray
$orders_ids_array = get_orders_ids_by_product_id( $product_id );
// We display the orders in a coma separated list
echo '<p>' . implode( ', ', $orders_ids_array ) . '</p>';
【讨论】：
我想指出，如果订单中有多个商品，上述答案将返回 order_id 的副本。
例如
如果有一个名为“apples”的产品，product_id=>1036
客户将“苹果”放入购物车 3 次并购买，创建 order_id=>555
如果我查询product_id->1036，我会得到array(555,555,555)。
可能有一种 SQL 方式可以更快地执行此操作，（感谢任何可以添加到此的人），否则我使用：array_unqiue() 来合并重复项。
function retrieve_orders_ids_from_a_product_id( $product_id )
{
global $wpdb;
$table_posts = $wpdb->prefix . "posts";
$table_items = $wpdb->prefix . "woocommerce_order_items";
$table_itemmeta = $wpdb->prefix . "woocommerce_order_itemmeta";
// Define HERE the orders status to include in <== <== <== <== <== <== <==
$orders_statuses = "'wc-completed', 'wc-processing', 'wc-on-hold'";
# Requesting All defined statuses Orders IDs for a defined product ID
$orders_ids = $wpdb->get_col( "
SELECT $table_items.order_id
FROM $table_itemmeta, $table_items, $table_posts
WHERE $table_items.order_item_id = $table_itemmeta.order_item_id
AND $table_items.order_id = $table_posts.ID
AND $table_posts.post_status IN ( $orders_statuses )
AND $table_itemmeta.meta_key LIKE '_product_id'
AND $table_itemmeta.meta_value LIKE '$product_id'
ORDER BY $table_items.order_item_id DESC"
);
// return an array of Orders IDs for the given product ID
$orders_ids = array_unique($orders_ids);
return $orders_ids;
}

如果您希望您的代码在未来的 WC 更新中工作，最好使用 WC 提供的函数从 DB 中获取详细信息，因为 WC 经常更改 DB 结构。 我会尝试类似：
function get_orders_id_from_product_id($product_id, $args = array() ) {
//first get all the order ids
$query = new WC_Order_Query( $args );
$order_ids = $query->get_orders();
//iterate through order
$filtered_order_ids = array();
foreach ($order_ids as $order_id) {
$order = wc_get_order($order_id);
$order_items = $order->get_items();
//iterate through an order's items
foreach ($order_items as $item) {
//if one item has the product id, add it to the array and exit the loop
if ($item->get_product_id() == $product_id) {
array_push($filtered_order_ids, $order_id);
break;
}
}
}
return $filtered_order_ids;
}
使用示例：
$product_id = '2094';
// NOTE: With 'limit' => 10 you only search in the last 10 orders
$args = array(
'limit' => 10,
'orderby' => 'date',
'order' => 'DESC',
'return' => 'ids',
);
$filtered_order_ids = get_orders_id_from_product_id($product_id, $args);
print_r($filtered_order_ids);

修改了获取特定用户产品ID的函数
function retrieve_orders_ids_from_a_product_id( $product_id,$user_id )
{
global $wpdb;
$table_posts = $wpdb->prefix . "posts";
$table_postmeta = $wpdb->prefix . "postmeta";
$table_items = $wpdb->prefix . "woocommerce_order_items";
$table_itemmeta = $wpdb->prefix . "woocommerce_order_itemmeta";
// Define HERE the orders status to include in <== <== <== <== <== <== <==
$orders_statuses = "'wc-completed', 'wc-processing', 'wc-on-hold'";
# Requesting All defined statuses Orders IDs for a defined product ID
$orders_ids = $wpdb->get_col( "
SELECT DISTINCT $table_items.order_id
FROM $table_itemmeta, $table_items, $table_posts , $table_postmeta
WHERE $table_items.order_item_id = $table_itemmeta.order_item_id
AND $table_items.order_id = $table_posts.ID
AND $table_posts.post_status IN ( $orders_statuses )
AND $table_postmeta.meta_key LIKE '_customer_user'
AND $table_postmeta.meta_value LIKE '$user_id '
AND $table_itemmeta.meta_key LIKE '_product_id'
AND $table_itemmeta.meta_value LIKE '$product_id'
ORDER BY $table_items.order_item_id DESC"
);
// return an array of Orders IDs for the given product ID
return $orders_ids;
}
使用示例
## This will display all orders containing this product ID in a coma separated string ##
// A defined product ID: 40
$product_id = 40;
// Current User
$current_user = wp_get_current_user();
// We get all the Orders for the given product ID of current user in an arrray
$orders_ids_array = retrieve_orders_ids_from_a_product_id( $product_id, $current_user->ID );
// We display the orders in a coma separated list
echo '<p>' . implode( ', ', $orders_ids_array ) . '</p>';
