sorting passed data

Hi!

I have on one my product page multiple products linked with ID of the
product.
Product name, bla bla bla, "click for more ".

So when you click on "more" you get additional info about product.
The problem is how to separate this data ( coming from product page ) and
how to read then this extra data from the db.
Should i make case, multiple if's or is there better option ?

Thanx
