    if(!$this->session->userdata('shortlist')['docid']) 
    { 
      $this->session->set_userdata('shortlist',$shortlist); 
    }else{ 
      $session = $this->session->userdata('shortlist')['docid']; 
      if(!in_array($_GET['id'],$session)) 
      $session[]=$_GET['id']; 
      $this->session->set_userdata('shortlist',array('docid'=>$session));
