Cannot give users 'No role for this blog'

[TheDeadMedic]

Blog admins cannot give users 'No role for this blog'.

Problem lies in function get_editable_roles, whereby if a role does not exist in the returned array, WordPress dies with the error "You can’t give users that role.".

Proposed fix;

function get_editable_roles() {
	global $wp_roles;

	$all_roles = $wp_roles->roles;
	$editable_roles = apply_filters('editable_roles', $all_roles);

        // allow for no role
        $editable_roles[''] = true;

	return $editable_roles;
}

However, this would also require a revision of wp_dropdown_roles;

function wp_dropdown_roles( $selected = false ) {
	global $wp_roles;
	$p = '';
	$r = '';

	$editable_roles = get_editable_roles();

	foreach( $editable_roles as $role => $details ) {

                // skip if blank (no) role
                if ( empty($role) ) continue;

		$name = translate_user_role($details['name'] );
		if ( $selected == $role ) // Make default first in list
			$p = "\n\t<option selected='selected' value='" . esc_attr($role) . "'>$name</option>";
		else
			$r .= "\n\t<option value='" . esc_attr($role) . "'>$name</option>";
	}
	echo $p . $r;
}

Can you give more detail on the use case for this.

Why do you need users without roles

[TheDeadMedic]

I just thought since this used to be a possibility in previous versions, it should still be available.

Plus it is quite handy if (for whatever reason) you do not want to delete a user, but do not want them to have any access to the blog admin.

NB: Sorry for using incorrect keywords.

If this feature has been removed from core, then why is the option still available in the front-end?

You can still select the option "No role for this blog" from the edit user page on the dashboard, but, "You can't give users that role"

As TheDeadMedic says, it is quite handy if you don't want to delete a user, but want to disable their access for whatever reason!

UI-wise, rather than have something like "no role for this blog" but still in the main list, it would be more user-friendly to be able to "retire" or "suspend" a user and have Retired or Suspended (or whatever) be the name of a role/status with no privileges, just a user record.

I can see your point, but that might get a bit confusing if it gets rolled into MU

For example, where site admin's can edit users in a blog back-end the user is not a member of, role will be marked/selected as 'no role for this blog'.

Adding to this, if you share user/usermeta tables between installs, users in the second install are all defaulted to "No role for this blog". But if you give someone a role, you can't revoke it. Kind of annoying. MU/MS also exposes this IIRC.

Simple fix for the notice. if ( !$editable_roles[$new_role] ) should become:

if ( !isset($editable_roles[$new_role]) || !$editable_roles[$new_role] )
