    $this->form_validation->set_rules('e_name', 'Event Name', 'required');
    if ( $this -> form_validation -> run() === FALSE )
    {
        $this->index();
        //redirect(base_url().'');

    }
    else
    {

        $event_data=array(
            'event_name'=>$event_name,
        );
        $this->home_model->insert_event($event_data);
    }
}

To redirect to an anchor in CI you should use redirect function like this :

redirect('/controller/function#anchor', 'refresh');

Hope that helps
