Question

自一个月以来，我想从完整的订单中获取产品的元数据（_wcj_purchase_price）。

我尝试使用MYSQL和WP_Query，但很快就迷失了。

实际上，我具有该产品的meta_value：

SELECT post_id as order_id, meta_key, meta_value from wp_postmeta where post_id in ( SELECT ID FROM wp_posts WHERE post_type = 'shop_order' and post_date BETWEEN NOW() - INTERVAL 30 DAY AND NOW() ) and meta_key = '_wcj_purchase_price'

但是我不知道要为每种订购的产品获得此值。

Answer 1

在@ dan-webb的帮助下，我得到了以下结果：

SELECT post_id as order_id, meta_key, meta_value from wp_postmeta where post_id in ( SELECT ID FROM wp_posts WHERE post_type = 'shop_order' and post_date BETWEEN NOW() - INTERVAL 30 DAY AND NOW() ) and meta_key = '_wcj_purchase_price'

但是它返回的是产品元数据，而不是订购的产品。

MySQL方式为：

SELECT post_id as order_id, meta_key, meta_value from wp_postmeta where post_id in
         ( SELECT ID FROM `wp_posts`  
           WHERE post_type = 'shop_order' and post_date BETWEEN NOW() - INTERVAL 30 DAY AND NOW()
          )                                         
and meta_key  = '_wcj_purchase_price'
