I wish to display the consumer role area within the wordpress user registration form.

I didn't use whatever option make up the admin side.

The way I actually do this? To ensure that the consumer choose his role within the registration form. If he's students he then will choose student role otherwise staff.

Any help?

In Wordpress, the roles are saved in $wordpress_roles global variable. So, if you wish to display all of the roles do this:

global $wp_roles;

foreach ($wp_roles->roles as $role) {
    echo $role['name'];
}
