Add user settings to specific roles

On the profile page exists a global variable $profileuser. The member $profileuser->roles is an array of all roles for that user.

<?php # -*- coding: utf-8 -*-
// Plugin Name: personal_options

add_action( 'personal_options', 'print_user_roles');

function print_user_roles()
{
    global $profileuser;

    print '<pre>$profileuser->roles="
        . htmlspecialchars(
            var_export( $profileuser->roles, TRUE ), ENT_QUOTES, "utf-8', FALSE
        )
        . '</pre>';
}

Output:

$profileuser->roles = array (
  0 => 'administrator',
  1 => 'editor',
)

Use this list to compare the roles.
