Best way to drill down through a parts database

[lupercale]

Hi Im trying out PHP and have a question.

I want to create a DB that will contain a selection of car parts.

I want the user to select a make.

Then select a model

Then select a type of car part.

What is the best way to do this. Should I save the make and model as a cookie and then search the whole DB or is there a better way?

The DB contains only 200 records.

Thanks

There is no need for cookies here (they are too fattening). Just pass the make and model as a hidden field in the form.
