Hi all, it's something I've been needing to do for a while, and that is to filter results on the page such as my example below (although they use ASP.NET but you can get a feel of what I'm wanting to achieve). Quite like their way with check-boxes to filter.
Click here to view example.
Once that fundamental base layer is working, you can use scripting to remove the [Update] submit button, and on a change of the checkbox you can request the content via AJAX instead.
Get the fundamentals working first though, otherwise you'll be screwed when client-side scripting is not available.
There's a good book called [Bulletproof AJAX, which also provides the [url="http://bulletproofajax.com/code/"]code and demo pages](http://bulletproofajax.com/) online, which takes you through these issues and how to successfully handle them.
