dynamic drop down boxes

[Anon]

I was wondering if there's a way to implement dynamic drop down boxes with php.

If I select an item in one drop down box, I would like it to query the database to update another drop down box which is on the same page. I know there's an onchange() for javascript but since I need to access the database, I will need to use php. Is there a way to do this??

there is no way to use php. php is an on-server language. you ned to use a client-side language. Or, you could have frames. Put one drop-down in the top and the second on the bottom. Then, put onchange(bottom.history.reload()) in the first drop-down.
