Purchase prerequisites?

-- HikaShop version -- : 2.3.2
-- Joomla version -- : 3.3.3
-- PHP version -- : 5.4.31

Is there any way to create 'prerequisites' for products?

i.e. Product B only is displayed/available to users if they have already purchased Product A.

also, the inverse...

Product A is no longer displayed if they have purchased it once.

I've searched and can't find anything that might help with this.

Jerome,

Thanks. That makes sense for the first part; however, how would I do the 2nd part:

Product A is no longer displayed if they have purchased it once.

The 'access level' option doesn't allow me to include a 'not' operator, or any complex/compound logic on groups.
And the 'User group after purchase' doesn't give me the option of 'removing' a user group upon purchase.
Either of these would make this process pretty easy.

With the existing features of HS how would I make Product A work as indicated above?

OK ... I think I can figure out a solution using these ideas; however, I think it would be a REALLY good idea to consider adding this sort of feature into the core of HS. Several other ecommerce extensions have this functionality and it seems to be a 'core' function that would be processed more efficiently with code specifically for this task.

Maybe somebody could create an extension just for this functionality???
