I managed to get post_object working nicely, which lets me link two posts with each other with linkable titles. However, now I have some problems when trying to assign multiple authors to one post (using “Relational” > “User” field in back-end) and then list the assigned authors on a post, with their names as links.
For example, every author is separated by a comma and their names are linkable which link them with their own WP users page.
Could someone please point me to the correct code? Searched through this forum but found nothing.
