Add new role for sub-sites WPMU

Question

I want to add a new role for all subsites in WPMU, so I created a file and tried the famous code on it (after including wp-blog-header.php):

$result = add_role(
    'ret_moderator',
    'مدیر بازنشسته',
    array(
        'read'         => true,  // true allows this capability
        'edit_posts'   => true,
        'delete_posts' => true, // Use false to explicitly deny
        'delete_published_posts' => true,
        'publish_posts' => true,
        'upload_files' => true,
        'read_private_pages' => true,
        'read_private_posts' => true,
        'edit_published_posts' => true,
        'edit_pages' => true,
        'manage_categories' => true,
        'manage_links' => true,
        'list_users' => true
    )
);

It adds the role for the main blog, but it's invisible on the sub-sites :) My own idea is to place the code inside somewhere like themes and open it on sub-sites (:D) but you know that isn't standard approach.

Answer 1

The problem is that you placed it in the theme of the main blog.

For it to run on all blogs you should create a plugin for wordpress, place your code there and than enable it to the entire network (from the super admin panel).

Good luck :)
