Yes, just filter ‘user_has_cap’. You get an array with the current capabilities that you can change without touching the database. Sample Code add_filter( ‘user_has_cap’, ‘wpse_53230_catch_cap’, 10, 3 ); /** * See WP_User::has_cap() in wp-includes/capabilities.php * * @param array $allcaps Existing capabilities for the user * @param string $caps Capabilities provided by map_meta_cap() * @param array … Read more

I use User Role Editor. You can delete added roles, and reset roles from the plugin page. To reset the administator role, you can, as of WP 3.4+, add define(‘URE_SHOW_ADMIN_ROLE’, 1); to your wp-config.php file. After having done so, you need to go to Users > User Role Editor and click “Reset”.
You cannot assign capabilities to unknown users. If you want to make a post visible for everyone, create a separate URL for these posts and add a control element to the post editor to enable the preview on selected posts only. When such an URL is called, check if a preview is allowed for the … Read more

Use the user ID and WP_User: $user = new WP_User( $user_id ); print wp_sprintf_l( ‘%l’, $user->roles ); Update /** * Get user roles by user ID. * * @param int $id * @return array */ function wpse_58916_user_roles_by_id( $id ) { $user = new WP_User( $id ); if ( empty ( $user->roles ) or ! is_array( … Read more
There may be some different way to do that, but most proper way to do that is following. <?php $args = array( ‘role’ => ‘Your desired role goes here.’, ‘orderby’ => ‘user_nicename’, ‘order’ => ‘ASC’ ); $users = get_users( $args ); echo ‘<ul>’; foreach ( $users as $user ) { echo ‘<li>’ . esc_html( $user->display_name … Read more
