How can I hide content id on URL

maybe it will be more better if I can show the codes


pages_model.php

PHP Code:

   public function getMakale($id)
   {
       $record = $this->db
                           ->from('makale')
                           ->where('id', $id)
                           ->where('status', 1)
                           ->get()
                           ->row();
       
       if (empty($record)) {
           return FALSE;
       }
       
       $record->user = $this->getUser($record->user_id, 1, NULL, FALSE);
       
       return $record;
   }
   
   public function getMakaleKategori($id)
   {
       $record = $this->db
                           ->from('makale_kategori')
                           ->where('id', $id)
                           ->where('status', 1)
                           ->get()
                           ->row();
       
       if (empty($record)) {
           return FALSE;
       }
       
       $record->makaleler = $this->getMakaleKategoriToMakale($record->id);
       
       return $record;
   } 


--------------------------------------------------


controller - pages.php

PHP Code:

 public function makale()
   {
       $id = (int) $this->uri->segment(2);
       $record = $this->pages_model->getMakale($id);
       
       if (empty($record)) {
           $this->site->set_alert('error', lang('makale-not-exist'));
           redirect('makaleler');
       }
       
       $this->pages_model->updateHit('makale', $record->id);
       $record->hit = $record->hit + 1;
       $this->data['record'] = $record;
           
$this->site->breadcrumb('Makaleler', 'makaleler', '');
$this->site->breadcrumb($record->baslik, '', '');
       
$this->site->title($record->baslik);
$this->site->description($record->meta_description);
$this->site->keywords($record->meta_keywords);
       
$this->load->view('makale', $this->data);
   }
