I don't know what flavour of SQL you are using (you haven't told us),
but whatever one you are using, I would combine those 2 queries into a
single JOINed query.
However according to what you first said "I have two tables products
and dealers.", but your queries are on "products" and "prices"???
Assumming that "prices" should be "dealers" ,the query will likely look
something like:
SELECT * FROM products, dealers WHERE seatsfrom = ? AND dimwidth <= ?
AND
dimhight <= ? AND dimlength <= ? AND type = ? AND shape = ?
AND products.tubid = dealers.tubid
However if you can tell us precisely what SQL you are using, we can be
more helpful.
Also you don't tell us what trouble you are having creating a search
page?
Is it that you don't know how to construct an HTML form?
Is it that you don't know how to use php to access submitted values?
Is it that you don't know how to use the api to your dbms?
Is it ...
Please help us to help you!
