Hi:
Every one:

I want to add some products(fittings) below shopping_cart.php page ,when the customers have a products in cart,and then if he also add a fittings into the cart,then the fitting get 20%(or other) discount,
if he only buy the fittings ,the price is full price(no discount at all).
I add "if "(red part) into shopping_cart class ,it also normal,but i have judge all in card product subset of fittings,it no any discount,how to calculate?

 function calculate() {
      global $languages_id;// Eversun mod for SPPP Qty Price Break Enhancement
      $this->total_virtual = 0; // ICW Gift Voucher System
      $this->total = 0;

      if (!is_array($this->contents)) return 0;

      reset($this->contents);
      while (list($products_id, ) = each($this->contents)) {

       if ($product = $pf->loadProduct($products_id, $languages_id)) {
