I have two content types, Parent and Child. Parent contains a list of tagged users which may create Child. Child contains the tag of the Parent.
On the Parent page I need a link, which is only visible to people tagged in it, to create a new Child with the Parent already tagged in it.
I know I need to use something like Entity Reference Prepopulate but my problem is that I can't figure out how to make the link.
This seems like it should be a simple thing to do but I can't for the life of me figure out how!
The requirement is that this should only use the UI and without editing any .php files as there is no guarantee that other devs will be able to code and allows easy visual recognition of what has changed.
Any advice would be greatly appreciated.
