Take a look at this article from the Evolt website to begin.
http://www.evolt.org/article/Accessible_Interdependent_Select_Boxes/20/60163/index.html
As a hint, you will perform all of the data-gathering in PHP for all the
possible combinations. First read the article and take some quick notes
on the information you need to provide to the browser to make all the
javascript work correctly. Next, do all of your PHP and MySQL queries
to gather that data and then use PHP to write out the proper select
fields (comboboxes in Microsoft lingo) and supporting data. Then
implement the system in the article, itself.
The PHP and MySQL part of this task are not the most challenging part of
the job, the challenging part is the dynamic behavior that Chris
Heilmann has outlined in the article. All of the PHP work is simple:
get info, loop over records, output key datapoints. You will want to
keep a browser window open to http://www.php.net while you get familiar
with the details of the various PHP functions/methods you will use. The
rest should provide a good exercise for the reader.
