keep data in codeigniter without flash data - php

Question

I created a management system in codeigniter that loads data from the database in datatables for specific suppliers. When the user clicks at any of these data rows he is navigating to each supplier's company products. My problem is that I want to find a session or something else that will keep the data of the previous selected rows when the page reloads. At the moment I am using flashdata but when I go back a step or return to the previous page all the data from the database disappear. What I want is something that will keep my data even if I am reloading the page or if I go back a step.
That's my controller:
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', $arr);
That's one of my first table view file with suppliers:
<div class="row-fluid sortable">
<div class="box span12">
<div class="box-header" data-original-title>
<div class="box-icon">
<i class="halflings-icon wrench"></i>
<i class="halflings-icon chevron-up"></i>
<i class="halflings-icon remove"></i>
</div>
</div>
<div class="box-content">
<table id="suppliertable" class="table table-striped table-bordered bootstrap-datatable datatable">
<thead>
<tr>
<th>Supplier</th>
<th>Open Range</th>
<th>Fill Content</th>
<th>Total Match</th>
</tr>
</thead>
<tbody>
<?php foreach($dash_present_all_suppliers as $v): ?>
<tr>
<td class="center" style="color:#0c595b;"><?php echo $v['supplierCompany']?> </td>
<td class="center">70%</td>
<td class="center">12%</td>
<td class="center">82%</td>
</tr>
<?php endforeach; ?>
</tbody>
</table>
</div>
</div><!--/span-->
</div>

Instead of using $this->session->flashdata() user the normal session i.e. $this->session->userdata() to store the temp browse data and write a cron which will delete this session in a regular interval or at the time of logout or any desired specific action.
Hope this will give better approach n help you in solving your problem
