How can I add a filter to let user pick selection criteria for what to display?

[mccollin]

I have a vBadvanced block that pulls articles based on certain criteria. It actually is using some custom fields (via GARS) and I've got a PHP module that pulls what I want... I can manipulate the criteria via a variable in the PHP program and get what I want. What I'd like to do is add a filter at the top of the block that lets the user pick the criteria, rather than having to have a lot of different pages for every different combination of criteria.

As an example to keep it simple... I have news about cars and the default may be to show all news... however I'd like the user to be able to set a filter for Ford, Chevy, or Dodge... and then have it regenerate the results to match the filter. How would I create the filter, and how would I pass it to the php file and get it to regenerate the page?

Thanks.

I figured it out... wasn't as tough as I thought it was... I just created a small javascript menu and directed the choice to a different url... with a variable for my selection... and then used $_REQUEST to retrieve it in my .php module.
