This isn't right, Chocks.
And I'm now virtually certain - after trying a few other things - that
granular / "special" capabilities on custom post types is broken in 3.0.
As to your code, Chocks, you can submit your posts for review. It still
shows the "not allowed" error in the editor, though it does allow
submission anyhow. Problem is every other "contributor" can edit your
posts too. I think it's getting confused by the existence of the meta
capability in the roles primitive capabilities.
I'm 99% certain WordPress should handle the meta capabilities (the
"singulars") on its own (we should not have to assign those).
Here's some pretty basic code (from my functions file) that registers a
new custom post type with a special (non-default) 'capability_type'. It
is followed by some code that adds a new role with the plural 'edit_'
capability (they still get errors trying to edit content or submit for
review). That latter block of code also and adds every other custom
plural capability to roles with similar (generic) post roles, yet
administrators cannot edit others posts!
I can confirm that this code gives the "guestblogger" role
"edit_guest_posts" capability, and that the 'guest-blogs' content type
has 'edit_guest_posts' as the value of its 'edit_posts' capability.
Andrew - I'd really like your opinion on whether there's something wrong
with this code, and if not, whether the roles work as expected for you.
'label' => 'Guest Posts',
'singular_label' => 'Guest Blog Post',
'description' => 'Guest blog posts from the members.',
'public' => true,
'capability_type' => 'guest_post',
if ( !get_role('guestblogger') )
if ( !isset( $wp_roles ) ) $wp_roles = new WP_Roles();
$caps = $wp_roles->get_role('subscriber')->capabilities; //let's
use the subscriber as the base capabilities
$wp_roles->add_role( 'guestblogger', 'Guest Blogger', $caps );
$wp_roles->add_cap( 'guestblogger', 'edit_guest_posts' );
// add guest blogger capability to others
foreach ( $wp_roles->role_objects as $role ) :
if ( in_array( 'edit_posts', $role->capabilities ) )
$role->add_cap( 'edit_guest_posts' );
if ( in_array( 'publish_posts', $role->capabilities ) )
$role->add_cap( 'publish_guest_posts' );
if ( in_array( 'edit_others_posts', $role->capabilities ) )
$role->add_cap( 'edit_others_guest_posts' );
if ( in_array( 'read_private_posts', $role->capabilities ) )
$role->add_cap( 'read_private_guest_posts' );
