He intentado y conseguido ayuda de desbordamiento de pila tipo miembro del equipo y llegó hasta este nivel, sin embargo, tengo que ir un paso más cerca de resolver .Sin embargo, cuando Estoy tratando de pasar el parámetro que se concatena, ejemplo me pasa como parámetro l/59. Una vez que pasa este parámetro, debe recuperar los datos pertinentes de la tabla denominada st_dak_details , y quiero que los datos recuperados de la tabla a rellenar en otra página de vista . Pero no es trabajo, es decir, no llegar pobladas.

**first view page where I pass parameter**

<div class="col-sm-7 col-md-6 col-lg-4">
                <button type="reset" class="btn btn-default" >Reset <span class="glyphicon glyphicon-refresh"></span></button>
                <button type="button" class="btn btn-success" id="getbtn" onclick="loadPagcontente('<?php echo site_url()?>/UsermanagementController/forwardtrack')" >Get Detais <span class="glyphicon glyphicon-ok"></span></button>

                <!-- <button type="button" class="btn btn-success" id="getbtn" onclick="loadPagcontente('<?php //echo site_url()?>/UsermanagementController/forwardtrack')">Get Detais <span class="glyphicon glyphicon-ok"></span></button> -->
            </div>

 **Inside Controller**

function forwardtrack($param='',$param2='') {
if(sizeof($this->db->get_where('st_forward',array('letter_no' =>$param.'/'.$param2))->result_array())>0 && (!($param.'/'.$param2) )){
    $data1['message']= 'notallow';
    $this->load->view('track1',$data1);
}
else{
    $data1['name']=$this->db->get_where('bpas_user_profiles',array('AgencyMainParentID' =>$this->session->userdata('ministryId'),'AgencyParentID'=>$this->session->userdata('parentID'),'AgencyID'=>$this->session->userdata('agencyID')))->result_array();

$data1['userdeatils']=$this->ag->tracks($param.'/'.$param2); 
$this->load->view('userManagement/forward2', $data1);
}

   /* ag=> agency model */


}

**Inside model**
public function tracks($letterno="")
    {   



     $query= $this->db->get_where('st_dak_details',array('dakLetterNo'=>$letterno));
      if ($query->num_rows() > 0) {
            return $query->row();
      } else {
            return array();

I expect concatenated  parameter  that I passed from first view page to retrieve data from table and populate it into the final view page.
