Filter results via selectbox!

How can I filter Results by County,District,City with dropdown select.

Is there a way to do it in Cake way, because currently I'm doing it classic way, by passing Id 开发者_运维问答to url, like:

/sort/county_id/1/district_id/5

But this is very bad hack, because I have to explode $this->here and not good thing. I don't know if there is uri class like in codeigniter, so I can play with $this->uri->segment().

In fact my problem is that I need to see if isset then pass it.

Have you considered named parameters?
