解决OSCommerce中“旧”商店的问题。它是一个多线程配置，由前一个所有者调整。我有2个类似的产品，有价格表或价格价格突破功能。
问题是2种产品中有1种在添加到购物车或显示产品页面时没有反应一致。
1st product：价格表包含＆gt; 5，＆gt; 10，＆gt; 20和＆gt; 30，价格从高到低。
2nd product：具有相同的时间表，但以某种方式反过来显示：＆gt; 30，＆gt; 20，＆gt; 10和＆gt; 5，价格从低到高。
奇怪的是，价格计划表中不存在选项sort_order，因此显示数量订单的方式是随机的，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意数量的最高价格，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：
以下是生成price_schedule的类的代码：

据我了解您的问题，您希望始终如一地订购产品价格。我知道你提到的插件，但我对它们并不是很熟悉。话虽如此，你可以尝试改变这一行......
$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
$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");
正如我所说，我并不熟悉你提到的插件是如何工作的，但我首先要为mysql查询添加排序。这种方法在很多场合都适用于各种插件。
