Limit User Role to Certain Posts

There are a variety of plugins out there for managing user role access. User Role Editor (URE) and Advanced Access Manager (AAM) are both good plugins I can recommend. URE is great for…editing roles. The problem with URE is that it doesn’t allow more narrow scope restrictions…like a single post. AAM is great at limiting individual posts and hiding admin menus. AAM however requires a LOT of setup if you have a lot of pages / a lot of roles and starts to become unpractical for highly restrictive page editing.

All that said, I ended up turning to good ol’ taxonomies.

First, setup your taxonomy for your posts. In this case I am targeting a “Departments” custom post type.

See jp_register_cpt and jb_register_taxonomy for info on these functions.

Second, setup your roles with URE. I’ll leave this to you, but I usually start with copying either the “Contributor” or the “Subscriber” default roles and going from there. Mine looks like this:

Third, Add a new admin taxonomy in the new taxonomy you just created. Make sure to give it the same slug as the user role ID, this is just for ease of use later and for reference. Example:

Forth, add this function to your PHP file.

All done! Now this user role should not be able to view or edit any posts that do not have this category.
