$data = array(
'nf_editor' => $row->nf_editor,
'subject' => $row->subject,
'message' => $row->message,
'template_id' => $row->template_id
);

$this->db->where('template_id',$template_id);

I don't see where you are setting $template_id. I see where you are setting $data['template_id'], but not $template_id.
