php counter

Question

I am developing my first e-commerce site and have run into a slight problem with the page counter. As you can tell in my code below, I set my number/Pg and start page level vars as follows:

$numPerPage=3;
$start=0;

I know I am missing a limit in my SQL stmt, but do exactly know where. When I execute the SQL stmt with the limit, I am returned a page that displays ALL my products with the correct amout of pg numbers (e.g. what I would like is to have three products display/page starting with the first product...as indicated in my vars above. I am getting 32 products returned instead).

Any clues as to what I have done and what I need to do?

Thanks

I did not read over the entire thing there but you probably want to do something like this:

$oursql="select * from tblproducts" LIMIT $start,$end;

Then on your creation of numpages set start and end +10 results or something.

so that page one's sql when rendered says

$oursql="select * from tblproducts LIMIT 0,10";

then page 2 says

$oursql="select * from tblproducts LIMIT 10,20";

and so on...
