passing random variables names

Hi all, I made a form which pass constant variables which never change (Ex. product_name) and dynamic variables which i withdraw from the db (Ex. attribute_id = 1, value = color). Now my problem is with the passing of the dynamic variables. Because the fields can change their name (id's) i need to design my functions so they will "know" how to receive them. I used to make an array in the form (Ex. attribute_id[0], attribute_id[1] where the numbers in the [] are the id numbers from the db) and then at the function i used to $_POST['attribute_id'] and then withdraw from them their id's and values. I read that this kind of passing variables is making problems with javascripting (and maybe it violate W3C standards). Is there a way that i can pass names like attribute_id_X where X is the changing name and the function will be able to withdraw it like $_POST['attribute_id_X'], or any other way which doesnt violate W3C standards? Any help will be greatly appreciated, Thanks ------------------------------------------------------ "My friends are worth gold to me, so I prefer to sell them and get rich!"
