Php OSCommerce价格表不一致行为

与OSCommerce中的一家“老”商店合作解决问题。这是一个由前所有者调整的多存储配置。我有两个类似的产品，价格表或数量价格打破功能

问题是，当添加到购物车或显示产品页面时，2种产品中的1种反应不一致

：价格表为>5、>10、>20和>30，价格从高到低。
：具有相同的时间表，但以另一种方式显示：>30、>20、>10和>5，价格从低到高

奇怪的是，价格表中不存在选项排序顺序，因此显示数量顺序的方式是随机的，但总是从高到低或从低到高

第一个产品在购物车中显示正确的价格，第二个产品始终显示任何数量的最高价格，其中购物车应根据价格表数据调整价格

到目前为止没有任何运气：

• 已检查后端中的价格计划配置
• 在后端检查产品配置并在数据库中重新检查
• 检查了所有相关的数据库表
• 在发现产品之间的唯一区别是：产品名称、产品图像和产品id后，给产品一个与工作产品接近的产品id。还更改了所有相关数据库条目的
• 制作正确工作产品的副本，并添加价格表

以下是生成价格表的类的代码：

据我所知，您希望订购的产品价格保持一致。我知道你提到的插件，但我对它们不太熟悉。也就是说你可以试着改变这一行

$price_schedule_query = tep_db_query("select products_groups_price, products_groups_price_qty FROM " . TABLE_PRODUCTS_PRICE_SCHEDULES . " WHERE products_id = '" . $prices['products_id'] . "' and stores_id = '" . STORES_ID . "'");

到

正如我所说，我不太熟悉你提到的插件是如何工作的，但我首先要向mysql查询添加排序。这种方法在很多场合对我的各种插件都很有效。
非常感谢ndiggity，它非常有效，我只需将ASC改为DESC。
$price_schedule_query = tep_db_query("select products_groups_price, products_groups_price_qty FROM " . TABLE_PRODUCTS_PRICE_SCHEDULES . " WHERE products_id = '" . $prices['products_id'] . "' and stores_id = '" . STORES_ID . "'" . " ORDER BY products_groups_price ASC");
