我有一个打开的购物车网站，在一个页面上显示所有产品（如果用户选择查看此页面）。我试图按人气排序限制为1个特定产品类别（类别ID：23），而不是目前最新添加的类别。
我知道Opencart已经嵌入了热门功能，因为您可以根据“观看最多”和“购买最多”来查看管理部分中的报告。
请参阅下面的类别页面：

好的，我会尝试设置查询，你需要调用的方法，然后你就可以了。
这应该是为了获得所有（或使用LIMIT 10时的前10个）来自按类别降序排序的第23类产品
SELECT p.*, pd.*
FROM `product` p
LEFT JOIN `product_description` pd
ON p.`product_id` = pd.`product_id`
AND pd.`language_id` = {<YOUR_LANGUAGE_ID>}
LEFT JOIN `product_to_category` ptc
ON p.`product_id` = ptc.`product_id`
AND ptc.`category_id` = 23
ORDER BY p.`views` DESC
LIMIT 10
注意：不确定p.views列名称 - 在查询数据库之前检查一下。
如果您希望按购买的数量获得所有产品：
SELECT p.*, pd.*,
(SELECT COUNT(op.product_id)
FROM `order_products` op
WHERE op.product_id = p.product_id
) AS product_count
FROM `product` p
LEFT JOIN `product_description` pd
ON p.`product_id` = pd.`product_id`
AND pd.`language_id` = {<YOUR_LANGUAGE_ID>}
LEFT JOIN `product_to_category` ptc
ON p.`product_id` = ptc.`product_id`
AND ptc.`category_id` = 23
ORDER BY product_count DESC
LIMIT 10
注意：再次我不确定order_products表名...
尝试在phpMyAdmin中启动查询，如果有任何问题，请告诉我它们是否有效或发布错误消息...
