PayPal compatibility about pmpro-multiple-memberships-per-user

Use JavaScript to only allow users to select one level to purchase at a time

A. We want to limit the number of levels a user can "add". If they already have a level, it will be selected. We need to check if they are adding more than one level.

They also can remove levels from the levels page and we should let them remove as many as they want.

B. Ideally, it would be nice even to allow them to add multiple levels if all but one of those levels were free. To support this, we can localize some more data about the levels and denote which are free vs paid.

C. I also think initial payments are grouped together. So really we should only have to limit them to adding one recurring level. So they can add as many free or initial payment levels as they want, but only one recurring level at a time.

Maybe show users a notice as well if they try to select more than one

We should definitely notify the users when they've added 2 recurring levels. We should disable the continue button.

We should also double check all of this on the checkout page. Maybe in general when the levels are passed. Definitely in the registration_checks filter.

I was working on this issue a while back, not sure how far I got and would want to review the changes before continuing this update: https://github.com/dparker1005/pmpro-multiple-memberships-per-user/tree/issue_60

A customer sent in a ticket regarding support for PayPal Express:

I would like to have stripe an PayPal working at the same time, therefore I downloaded the Add On Paid Memberships Pro – Add PayPal Express Add On.

However, when I am in the check out page and selected Pay Pal, appear the following message

“You cannot check out for multiple levels simultaneously while using this payment gateway. Please complete each checkout separately.”

I have multiple memberships per user turned on. Users are unable to check with paypal when using the page with the pmpro checkout block on it with the selected level (just one level) on it, it gives them the attached error. However, if they use the default checkout page with just the [pmpro_checkout] shortcode on it, they can purchase the membership no problem.
