Is there any plugin or available code to change the way users get enroll in courses. We are going to have a large group of people that will enroll in the same course and we would like to avoid they pass the enrollment key each other. In order to that, there are two approaches:
1.- Every time a new user applies for enrolling in a particular course, a unique key course will be sent to him which will be totally different than others' key.
2.- When a user applies for a new course, this is directly enrolled through a small code that modifies the corresponding database's tables.
Is there anything that cover any of the above approaches?
Thank you very much.
