php - how does opencart calulate total amounts? -


i have 2 price fields in products table in database of opencart site. display of price determined type of user thats logged in.

throughout site have correct prices being displayed based on user, cant figure out how total price calculated.

        $total_data = array();         $total = 0;         $taxes = $this->cart->gettaxes();          $this->load->model('setting/extension');          $sort_order = array();           $results = $this->model_setting_extension->getextensions('total');          foreach ($results $key => $value) {             $sort_order[$key] = $this->config->get($value['code'] . '_sort_order');         }          array_multisort($sort_order, sort_asc, $results);          foreach ($results $result) {             if ($this->config->get($result['code'] . '_status')) {                 $this->load->model('total/' . $result['code']);                  $this->{'model_total_' . $result['code']}->gettotal($total_data, $total, $taxes);               }         }
