Thumbs Up and Down feature

I know there is a star rating feature for Yii but is there a method for rating let’s say a post up or down?

Why don’t utilize Ajax button? You can put image in the button for thumbs up/down.

Sweet, I got it to work somewhat, but I have a question for the URL part (still used to another style). But am, trying to call a method from my Post controller but also passing in 2 parameters. Now I do have the URL beautification turned on also.

Thank you so much for the above help :)
