Ich habe versucht und bekam Hilfe von stack-overflow-Art-team-Mitglied und erreicht bis zu dieser Ebene, noch ich haben zu gehen Schritt näher, um es zu lösen .Jedoch, wenn Ich bin versucht, übergeben Sie parameter, die verkettet ist, Beispiel ich pass parameter wie l/59. Sobald dieser parameter übergeben wird, sollte es abrufen von relevanten Daten aus der Tabelle mit dem Namen st_dak_details , und ich möchte die Daten aus der Tabelle zu füllen, es in einer anderen Seite anzeigen . Aber es funktioniert nicht, also nicht immer aufgefüllt.

**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>

function forwardtrack($param='',$param2='') {
if(sizeof($this->db->get_where('st_forward',array('letter_no' =>$param.'/'.$param2))->result_array())>0 && (!($param.'/'.$param2) )){

    $this->load->view('track1',$data1);

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

   /* ag=> agency model */


}

     $query= $this->db->get_where('st_dak_details',array('dakLetterNo'=>$letterno));
