Php 第二页不工作分页

我在使用codeigniter分页时遇到问题。问题是，当我在分页过程中打开第二页时，它显示错误

404 page not found

。我不知道为什么，但在第一页它是工作

型号：

    public function home($limit='',$segment=''){ 
    $data = array();
    $this->db->where(array('produk.status_produk'=>'1'))->limit($limit,$segment); 
    $i=0;
    foreach ($this->get_all() as $item){
        $data[$i] = $item;
        $this->db->where(array('produk_id'=>$item->id_produk,'default'=>'1'));
        if($this->db->get('foto_produk')->num_rows() > 0){
            $this->db->where(array('produk_id'=>$item->id_produk,'default'=>'1'));
            $foto = $this->db->get('foto_produk')->result();
            foreach ($foto as $pic) {
                $data[$i]->image = $pic->image;
                $data[$i]->thumb = $pic->thumb;
            }
        } else {
            $data[$i]->image = '';
            $data[$i]->thumb = '';
        }
        $i++;
    }
    return $data;
}

            $cari = $this->input->post('search');
        $this->db->like('deskripsi_produk', $cari);
        $this->db->or_like('nama_produk', $cari);
        $this->db->order_by('id_produk','desc');
        $t = $this->produk_m->home();

        $this->data->search = $this->input->post('search');

        $this->load->library('pagination');
        $perPage = 2;
        $uri_segment = 2;
        $total = count($t); 
        $config['base_url'] = site_url('search');
        $config['total_rows'] = $total;
        $config['per_page'] = $perPage;
        $config['num_links'] = '2';
        $config['uri_segment'] = $uri_segment;

        $this->pagination->initialize($config);
        $this->data->pagination = $this->pagination->create_links();

        $this->db->like('deskripsi_produk', $cari);
        $this->db->or_like('nama_produk', $cari);
        $this->db->order_by('id_produk','desc');
        $this->data->produk = $this->produk_m->home($config['per_page'],$this->uri->segment(2));


        $this->template->set_judul('PT Bintang Sriwijaya')
        ->set_css('style')
        ->set_parsial('sidebar','sidebar_view',$this->data)
        ->set_parsial('topmenu','top_view',$this->data)
        ->render('search',$this->data);   
}

控制器：

    public function home($limit='',$segment=''){ 
    $data = array();
    $this->db->where(array('produk.status_produk'=>'1'))->limit($limit,$segment); 
    $i=0;
    foreach ($this->get_all() as $item){
        $data[$i] = $item;
        $this->db->where(array('produk_id'=>$item->id_produk,'default'=>'1'));
        if($this->db->get('foto_produk')->num_rows() > 0){
            $this->db->where(array('produk_id'=>$item->id_produk,'default'=>'1'));
            $foto = $this->db->get('foto_produk')->result();
            foreach ($foto as $pic) {
                $data[$i]->image = $pic->image;
                $data[$i]->thumb = $pic->thumb;
            }
        } else {
            $data[$i]->image = '';
            $data[$i]->thumb = '';
        }
        $i++;
    }
    return $data;
}

            $cari = $this->input->post('search');
        $this->db->like('deskripsi_produk', $cari);
        $this->db->or_like('nama_produk', $cari);
        $this->db->order_by('id_produk','desc');
        $t = $this->produk_m->home();

        $this->data->search = $this->input->post('search');

        $this->load->library('pagination');
        $perPage = 2;
        $uri_segment = 2;
        $total = count($t); 
        $config['base_url'] = site_url('search');
        $config['total_rows'] = $total;
        $config['per_page'] = $perPage;
        $config['num_links'] = '2';
        $config['uri_segment'] = $uri_segment;

        $this->pagination->initialize($config);
        $this->data->pagination = $this->pagination->create_links();

        $this->db->like('deskripsi_produk', $cari);
        $this->db->or_like('nama_produk', $cari);
        $this->db->order_by('id_produk','desc');
        $this->data->produk = $this->produk_m->home($config['per_page'],$this->uri->segment(2));


        $this->template->set_judul('PT Bintang Sriwijaya')
        ->set_css('style')
        ->set_parsial('sidebar','sidebar_view',$this->data)
        ->set_parsial('topmenu','top_view',$this->data)
        ->render('search',$this->data);

请更改这些行

$uri_segment = 2;

到

及

到

请重试，因为段1用于控制器，段2用于其中的方法，段3可能是分页元素

$this->data->produk = $this->produk_m->home($config['per_page'],$this->uri->segment(3));
