Four roles to restrict user access on backend? WordPress

Sébastien | French WordpressDesigner comments:

Example :
if you add this code in your file functions.php
add_role('basic_contributor', 'Basic Contributor', array(
'read' => true, // True allows that capability
'edit_posts' => true,
'delete_posts' => false, // Use false to explicitly deny
));

a new role is created, his name is "basic_contributor"
with this role, i can read, delete post but no edit post.

You can custom your role as you want.
"red", "edit_posts" or "delete_posts" are capabilities and the list af all capabilities is here : http://codex.wordpress.org/Roles_and_Capabilities
Easy !

<blockquote>Thanks for your replies guys. On WPMS each blog have their own wp_user_capabilities so I'm having a hard time doing what you suggest.. </blockquote>
why ?

You must just add the new role in a file (functions.php)
and after you must assign this role to a user...

Yeap, I've done that:

$admin = get_role('administrator');
$caps = $admin->capabilities;

add_role('manejo_basico', 'Nivel Basico', $caps);
$role = get_role('manejo_basico');
$role->add_cap('manejo_basico');

add_role('manejo_paginas', 'Nivel Paginas', $caps);
$role2 = get_role('manejo_paginas');
$role2->add_cap('manejo_paginas');

add_role('manejo_paginas_posts', 'Nivel Paginas Posts', $caps);
$role3 = get_role('manejo_paginas_posts');
$role3->add_cap('manejo_posts');
$role3->add_cap('manejo_paginas');

But when I create a new user I can't assign any of those roles on the new subdomain.. and when I login into it I can then change the role of the user.

The other biggy is that new user with new role can't see the movies post type menu.. (gosh I don't know why!) which makes all this senseless.. I'm so close to finish the project: it's not for a client, it's for me, and it's driving me up the wall.

I don't mind (and this if for you as well Pippin) raising the amount of this question if you could help me out!.

Thanks

Joaquin.

If you want I can send you the details of the WP install.
