hi Mary
i have been looking more at the documentation and i found the following under examples of using meta courses:
Core subjects with fees based upon course groupings
You have 3 course subjects and want to offer them for sale in different packages. The meta courses will contain your subjects. A normal (non-Meta course) course will be the gateways to the meta course(s). Course 1 is your gold package. Meta course A, Meta course B and Meta course C all link to Course 1. The silver package is Course 2. Meta courses A and B link to Course 2. You have also set up individual courses that have a link from a specific Meta Course to them. Thus you can offer and charge for each meta course separately or in some combination.
This is pretty close to what i want to achieve. what i want to be able to do is automate the whole thing so that when someone pays for the course on my website thay are emailed an enrolment key and can then self enrol. i can sent an enrolment key email via my shopping cart no problem.
This would be self enroling to the Course 1 on the example above, which would then automatically enrol them to the unit metacourses linked to it.
does this sound feasable?
