Explanation of User Roles and Capabilities

Question

I'm developing a Wordpress theme. In this theme, there are a few custom post types.

Custom Post Types :

• book
• article
• event

We are using Wordpress' default user roles (we can create new roles, if necessary) .

Contributors just post new book and article . But they can't create event. Also they can't see, event menu item on wp-admin .

How can i do this ?

While registering new post type :

"map_meta_cap" => TRUE,
"capability_type" => "book",

And (on plugin activation)

$role = get_role( 'contributor' ); 

$role->add_cap( 'publish_books' );

But I think it's still not working. it's so complicated for me. I couldn't do it. I just want this roles and capabilities :

Administrator

Can see , post , publish everything

Contributors

Just can see, post to review book and article Can NOT see other post types on wp-admin menu.

Answer 1

You can create capabilities for each custom post type and add this to the different roles; see this answer from an question here.
