I have no manual to Prestashop database. Is there any? How are carts and atributes stored in database? Is it ps_cart_product? , I'm confused. How is it with attributes and quantity? I want to write static method with parameters id_product, color , size , material that returns quantity in system and the same in carts. It would be great if someone'd help. Thanx in advance, Jiri.
