将数据保存在没有flash数据的codeigniter中

我用codeigniter创建了一个管理系统，它从数据库中为特定供应商加载数据表。当用户单击这些数据行的任何一行时，他将导航到每个供应商的公司产品。我的问题是，我想找到一个会话或其他东西，将保持以前选择行的数据，当页面重新加载。目前我正在使用flashdata，但当我回到一步或返回到上一页从数据库中的所有数据消失。我想要的是一些东西，将保留我的数据，即使我重新加载页面或如果我回到一个步骤。这是我的控制器:

  public function __construct() {
    parent::__construct();
    $this->load->library('form_validation');
     $this->load->model('dash_match_model');
     $this->session->keep_flashdata('supplier_id');
     $this->session->keep_flashdata('segment');
     $this->session->keep_flashdata('class');
      $this->session->keep_flashdata('commodity');
     $this->load->library('session');
    $this->load->helper('url');
}
public function index() {
   $arr['page']='dash1';
   $user_id = $this->session->userdata('id');
   $supplier = $this->dash_match_model->dash_present_all_suppliers($user_id);
   $arr['dash_present_all_suppliers'] = $supplier;
    $this->load->view('clients/clDashboard',$arr);
}
public function select_supplier() 
{
    $supplier_name = $this->input->get('name', TRUE);

    $supplier_sel = $this->dash_match_model->selected_supplier_id($supplier_name);
    foreach ($supplier_sel->result() as $row){
        $this->session->set_flashdata('supplier_id', $row->supplier_id);
    }
    $selected_supplier = $this->dash_match_model->unspsc_matched_skus($this->session->flashdata('supplier_id'));
    $arr['dash_present_all_selected_suppliers'] = $selected_supplier;
    $this->load->view('clients/unspscSegment', $arr);
}
public function select_segment(){
    $segment = $this->input->get('segment', TRUE);
    $supplier_id = $this->session->flashdata('supplier_id');
    $this->session->set_flashdata('segment', $segment);
    $segment_sel =$this->session->flashdata('segment');
$selected_segment = $this->dash_match_model->unspsc_class($supplier_id, $segment_sel);
    $arr['dash_present_all_selected_segments'] = $selected_segment;
    $this->load->view('clients/unspscClass', $arr);
}
public function select_class(){
    $class = $this->input->get('class', TRUE);
    $supplier_id = $this->session->flashdata('supplier_id');
    $segment_sel =$this->session->flashdata('segment');
    $this->session->set_flashdata('class', $class);
    $class_sel = $this->session->flashdata('class');
    $selected_class =$this->dash_match_model->unspsc_commodity($supplier_id, $segment_sel, $class_sel);
    $arr['dash_present_all_selected_class'] = $selected_class;
    $this->load->view('clients/unsspscCommodity', $arr);

这是我的第一个带有供应商的表视图文件:
