I've added a custom user type in Wordpress, the custom post type supports Authors(See below). The custom user type has all the privileges of an author except for 'publish posts', but is not on the list of possible authors to assign to the post.

What am I doing wrong?


if (!get_role('member')) {
        add_role('member', 'SFUK Member', array(
            'delete_posts' => true,
            'edit_posts' => true,
            'read' => true,
            'upload_files' => true,
            'edit_published_posts' => true,
            'delete_published_posts' => true

and here is the custom post type :

$args = array(
    'labels' => $labels,
    'public' => true,
    'publicly_queryable' => true,
    'show_ui' => true,
    'query_var' => true,
    'rewrite' => true,
    'capability_type' => 'post',
    'hierarchical' => true,
    'menu_position' => 0,
    'supports' => array('title', 'editor', 'thumbnail', 'page-attributes', 'author')

if (!post_type_exists('ent')) {
    register_post_type('ent', $args);
    remove_post_type_support('ent', 'editor');


Let me know if more information is needed.


Does the user privileges work in wp-admin? the way you expect it to?... Also are you using a custom theme / widget to show the author name when published?, does it show a wrong value?, or just blank. There is alot of ways this could have been done wrong sadly =[

The authors dropdown is created the following call:

wp_dropdown_users( array(
    'who' => 'authors',
    'name' => 'post_author_override',
    'selected' => empty($post->ID) ? $user_ID : $post->post_author,
    'include_selected' => true
) );

The who argument means that only users with at least 'author' role will be listed, and the Codex page says that currently it's either 'authors' or empty (meaning all users). There is a filter for this function but it takes the HTML as input. You could create a new query for users and then output a new HTML dropdown. This is the first way to solve your problem.

However, this function with 'who' set to 'authors' searches for users whose level is not 0 which is quite strange since user levels have been deprecated long ago. I've found a related bug report on Trac recommending that you add a 'level_1' capability to your new role to fix this. This is not a clean solution but much easier than creating a filter and all HTML from scratch.

EDIT: A third and even more simple solution just came to my mind: I've created custom roles with plugins but never noticed this problem because I was always copying capabilities from existing roles and then modifying them. This way you won't forget any capabilities and it will also fix this bug.
