[wp-hackers] Adding a custom content type that only a particular role can create/modify

[Brent Shepherd]

Raj,

You need to map the wiki_page meta capabilities using the map_meta_cap
filter.

Doesn't help much does it? :)

It's best explained in code. Check out this file:
http://github.com/Prospress/Prospress/blob/master/pp-posts/pp-capabilities.php

There are three functions, each well commented enough for you to learn how
to manage the capabilities for a custom post type.

I've started work on a plugin to allow admins to manage capabilities for all
custom posts types, and to act as a guide to other plugin developers for
mapping meta caps. Once you get your head around it, if you'd like to help
write the plugin, let me know.

Brent
