Hello!
I would like to know if it is possible to filter the posts a user sees at wordpress admin. For example I want users of type simpleusers to only be able to see their own posts of a specific post type. Also, is it possible to bind a user with a taxonomy and only see posts that are connected to a specific taxonomy (e.g. only see posts with taxonomy Countries = Greece).
Thanks in advance.
Similarly, to bind the user to a particular taxonomy term, you can include a user custom field with the users that store the target taxonomy term's slug as a value.
You can then customize the code snippet shared above to include the taxonomy query to show only posts associated with that term.
