I have a CPT (Atendees) with several custom fields which is related to another CPT (Courses). I've managed to connect these fields in the backend, but now I need to populate the Atendees via front end form.
For the fronend I've used Fluent Forms which has MB support and I've succesfully managed to map and populate all the fields - all except the relationship.
I'd need to know:
The name of the relation is termin-pro-prihlasku, so I tried to map the field termin-pro-prihlasku_to (which was the ID of the respective admin column) and populate it with relevant Course ID. Unfortunately, it didn't work.
I've also tried MB Frontend Submission shortcode, but it didn't show the Relationship field at all - is MB Frontend Submission compatible with relationship?
Thank you for your reply.
