I would like to create a marketplace, I got the pages to create and view posts. I would like to access to a specific post that only the admin and the author could change. How do I call the current fields in the creation view? It could be only a button Edit in the view post that is visible for admin and author. But I do not know how to make appear the current value of fields in edit mode specifically for one post.
You can have an extra field on each post, say admin_only_editable of type yes/no and if it is set and the user logged in is an admin, you can show it.
