我想从php脚本（idoc脚本）修改标准搜索表单，添加3个下拉菜单供选择，并根据某些条件（如品牌，类别，文件类型和搜索词）显示结果
我试图添加条件＆＃34; AND＆＃34; /＆＃34; OR＆＃34;在查询上，但如果下拉列表的值为空（未选中），则不会显示或使用任何结果。
我想获取搜索结果从哪里可以选择3个条件之前如果需要减少id到sql数据库的数量，从这些条件，它将能够从名称，标签和描述选项卡中找到特定的关键字
如果指定了一个，两个，三个或没有下拉输入，您能否给我反馈如何修复搜索查询以减少/选择生成结果的id数量！
通常情况下，我可以在网上或本网站上找到解决方案，但我不知道该怎么做。
这是我的表单。

To understand what is happening on your wireless net work, you need to know where your users and devices are located – and you need to monitor the RF environment in those areas. The VisualRF module puts this information at your finger tips through integrated mapping and location data. VisualRF uses sophisticated RF fingerprinting to accurately display coverage patterns and calculate the location of every wireless device in rang\r\ne. Moreover, VisualRF does not require dedicated RF sensors or a costly additional location appliance – all the necessary information is gathered from your existing wireless access points and controllers.

我想我自己找到了解决方案。 但是我认为这个请求不必要地重。
有人知道我怎么能用symplifier？
