just redirect back to the "controller/function" that displays the form.

Code:

function function1() {
    if ($this->form_validation->run() == FALSE)
    {
        $data = array (
            '' => ''
        );
        $this->load->vars($data);
        $this->load->view('form');
    }
    else
    {
        $result = $this->model->add2db($this->input->post('field_01', TRUE));
        redirect('/controller/function1');
    }        
}
