The acf filter I linked to only works in the admin when editing and has no affect on the front of the site.
I think we are saying the same thing. Allow me to clarify. I want to modify the behavior of an ACF custom field of type ‘relationship’ on the admin side of WordPress when it populates in the target WordPress custom post type’s editor. I will handle how this data renders on the front end by coding the WordPress single-page template that I created for the custom post type. Does this clarify my goal?
Thank you, John, for providing a GitHub link to your work.
