Question

嘿伙计们试图在cakephp中创建一个高级搜索表单，

表格包括下拉列表，复选框（HABTM关系），文本字段和价格游侠（滑块），您可以看到以下表格：

enter image description here

如您所见，我有多个下拉列表，多个复选框等。

搜索效果很好，但我想要的是如何在网址上保存这些更改或过滤器，例如在用户选择了几个过滤器之后：

enter image description here

我希望网址如下： http://localhost/website/cakephpapplication/search?location=something&room_type=sth&accommodation_type=something& .... 所以一个

我使用的动作就是这个：

搜索效果很好，但我想要的是如何在网址上保存这些更改或过滤器，例如在用户选择了几个过滤器之后：

您希望实现将POST变为GET的the PRG pattern。

自己动手，wiki文章解释了模式，或使用现有的插件：
