我正在尝试构建一个搜索表单，允许用户选择特定的帖子标签并过滤房地产列表。到目前为止，我已经构建了表单，但当我单击搜索按钮时，它会将我带到网站的主页。然后，站点的url将更改为正常url，并在末尾添加此url，以显示正在使用的标准：/？位置=-1和；属性类型=46（&；sqft=-1和；床位=-1和；浴室=-1&；车库=-1
我猜我需要的是在PHP中编写某种post操作，确定要搜索的内容，并创建一个包含搜索结果的页面。我完全不知道该怎么做。我几乎没有数据库经验，也不知道如何用PHP连接WordPress变量。
我相信一定有一种更简单的方法可以做到这一点，我只是在四处搜索了几天之后还没有找到它。请在这里帮助我，并向我指出任何有用的资源或您可以做的任何事情。
下面是我如何构建表单的，改编自http://codex.wordpress.org/Function_Reference/wp_dropdown_categories:
编辑：此代码位于我的searchform中。php文件，我在网站的每个页面上都调用它
