       {
                      $widok['left'] = $this->get_category();
                      $widok['right'] = $this->get_bestseller();
                      $widok['zakupy'] = $this->sum_all();
                      $widok['licznik'] = $this->counter();
                      $widok['tytul'] = 'Wyszukiwanie';
                      $widok['center'] ='';



                       $config['base_url'] = 'http://lukaszbielecki.cba.pl/ksiegarnia/CI/index.php/site/get_books_by_keyword/';
                      
                            


                      
                       $this->db->like('BOOK_Title', $this->input->post('szukaj'));
                       $config['total_rows'] =  $this->db->get('books')->num_rows();
                       $config['per_page'] = 7;
                       $config['num_links'] = 10;
                       $query = $this->Kategorie_model->get_books_by_keyword();
                    


                      $this->pagination->initialize($config);


                      $config['per_page'] = 7;


                    
                      $config['uri_segment'] = 3;


          


                    if($query->num_rows() > 0)
                    {
                        foreach($query->result() as $data)
                        {
                            $widok['center'] .= $this->load->view('Ksiegarnia/book_searching',array('data' =>$data), true);
                            
                        }
                    }
                    else
                    {
                        echo 'no data';
                    }
            

         $widok['center'] .= '<div class="pagination">'.$this->pagination->create_links().'</div>';
           $this->load->view('Ksiegarnia/index_logged', $widok);
       }

Code:

function get_books_by_keyword()
       {
          
           $key = $this->input->post('szukaj');
           //echo $key;
