Conditional value lists?

[fishtech]

I am working on a store locator so consumers can find specific stores within a certain distance carrying specific products.

Searches are based on zipcode (textbox), proximity (textbox) and product (pulldown menu).

There are 250 products; 25 products in 10 different categories.

Rather than have the users choose from 250 products I would like users to be able to choose a category, then select from 25 products within that category all within a single webpage

A good example of this concept is here:

http://www.support.xerox.com/go/prodselect.asp?Xlang=en_US

Is anything like this possible with fx.php?

Or Would I need to have a 'category' search page before the zipcode/distance/product search page?

Thanks,

ft.

If you want to do it like the Xerox page you might note that the search options and conditions are in their own inline frames. This then allows them to do multiple queries without leaving the page.

The first selection targets the first frame and performs a search, returning a subset of records. A selection from that query then targets another frame and performs a search returning a further subset of records.

Each frame is actually a seperate page which has variables passed via the url (or GET variables) that are then used to perform searches. Other options are javascript or AJAX to simulate.
