Code:
public function view($page = 'index') 

    {

        if ( !file_exists('application/views/pages/'.$page.'.php') || $page == 'header' || $page == 'footer')

        {

            // Whoops, we don't have a page for that!

            show_404();

        }

        if( $page = 'index' ) {

            $this->load->library('pagination');

            $config['base_url'] = base_url('posts');

            $config['total_rows'] = $this->db->order_by("id", "desc")->get('Updates')->num_rows();

            $config['per_page'] = 5;

            $config['uri_segment'] = 3;

            $config['full_tag_open'] = '<div id="pages">';

            $config['full_tag_close'] = '</div>';

            $this->pagination->initialize($config);

            $data['records'] = $this->db->order_by("id", "desc")->get('Updates', $config['per_page'], $this->uri->segment(2));

        } 

        $this->load->model('panel_model');

        $data['math_captcha_question'] = $this->mathcaptcha->get_question();

        $this->load->view('header');

        $this->load->view('pages/'.$page, $data);

        $this->load->view('footer');

    }
