                                <?php endforeach ?>

اینم در قسمت model
function all_cate()

    {

        $all = $this->db->get('product') -> result_array();

        $data_send = array();

        foreach ($all as $key => $value) {

            $data = array();

            $ids = $value['id'];

            $data['id'] = $value['id'];

            $data['name'] = $value['name'];

            $data['hprices'] = $value['hprices'];

            $data['deals'] = $value['deals'];

            $data['dprices'] = $value['dprices'];

            $ids = $value['category'];

            $sql = "SELECT * FROM wa_categories WHERE id = $ids";

            $query=$this->db->query($sql); 

            foreach ($query->result_array() as $row)

            {

                $data['category']=$row['name'];                                             

            } 

            $data_send[] = $data;

        }

        return $data_send;

    }

و اینم در قسمت controllers
public function index()

    {

        $this->load->model('production_model');

        $data = $this->production_model->all_cate();

        $this->template->load('production' ,array('production'=>$data));    

    }
