[quote author="gtech" date="1211919526"]you don't have to use url segment if you don't want to either

Code:

function index($product_id)
{
...

will achieve the same thing.[/quote]
I like that! What if no param is passed, could you change $product_id into $product_id=null in the function declaration to handle either case?

I'm still a CI newbie too!
