我有这张桌子(wp_woocommerce_order_itemmeta):
此表(wp_woocommerce_order_items):
我使用的函数(functions.php)在数组中返回这些项ID:
function retrieve_orders_ids_from_a_product_id( $product_id, $order_date ) {
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-processing'";
# 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
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'
AND $table_itemmeta.meta_key LIKE 'order_date'
AND $table_itemmeta.meta_value LIKE '$order_date'
ORDER BY $table_items.order_item_id DESC"
);
// return an array of Orders IDs for the given product ID
return $orders_ids;
}
我在我的页面中调用它:
<?php $orders_ids_array = retrieve_orders_ids_from_a_product_id($getid, $order_date); ?>
我100%确定$getid
($getid
= product_id
)和$order_date
具有我的数据库中的确切值。
但如果我print_r
它返回的数组:
Array()
而不是任何价值。
最后我需要计算这些id-s,但如果没有返回任何东西,那对我来说是不可能的。

看起来像是
AND $table_itemmeta.meta_value LIKE 'order_date'
应该是
AND $table_itemmeta.meta_key LIKE 'order_date'
答案 1 :(得分:0)
好的,它有两个问题。第一:
for key, val zip(d['inds'], d['vals']):
应该是
AND $table_itemmeta.meta_value LIKE 'order_date'
,第二个是 AND $table_itemmeta.meta_key LIKE 'order_date'
总是刷新,因为我的$order_date
循环。
