[ad_1]
I needed to limit the user’s purchase to just 1 course. But if they wanted to buy a different course, there was no longer any limitation.
Let’s say I have 2 courses (Course Y and Course X).
I want the user to only be able to buy course Y once and not be able to add the same course to their cart again. But if the user wants to buy course X, this would already be possible.
In short, I’d like to know if it’s possible to limit course purchases to just 1 unit.
Is that possible?
