通过下拉列表过滤数据库表

Question

I need to filter the table depends on the selected values of the drop-down lists.我需要根据下拉列表的选定值过滤表。 So know I need to know how to return the filter result into the page.所以知道我需要知道如何将过滤结果返回到页面中。 I made the filter result in search.php but I can't return the filter result to the table again.我在 search.php 中制作了过滤结果，但我无法再次将过滤结果返回到表中。 The filter should filter by user ID or product ID for now.过滤器现在应该按用户 ID 或产品 ID 进行过滤。
