Change 2 features PHP store

Hello,

I have a game store of Minecraft game, I have products in different categories that when you buy you have to enter a username so that the advantages are added to the game.

I have two categories which you can buy 10 types of ranks and each one is the improvement of the previous, so I have a category which makes if the user "Test" (Example) wants to buy the product that will upgrade from the first rank to the second rank, you need to have bought the first rank above. In the administration panel in the configuration of each product, you can choose which products that are currently created, I want you to have each user purchased to be able to buy the product that I am configuring, but the problem is that I need to change the code in this way. Currently the page is: If I choose 2 products required, the user will need the two ranks, but I want to require the rank A or B, and for example if add 5 productos or 10 in the same way, you only need to have bought one of those 5 or 10.

That's one of the things that I need to change the PHP code of the store. I also need you to solve the cart because now if you add more than 1 product the require product does not work and I need that users can not buy ranks updates that user is not allowed. I hope you have understood.

Thank you.
