Hi Guys,

 

I'm implementing a promotion on a site - Buy 2 get 1 free on everything.

 

Magento has a similar promotion by default which only applies on an individual product and not on all products in the cart!

 

So, here's the default code:

 

case 'buy_x_get_y':
                   $x = $rule->getDiscountStep();
                   $y = $rule->getDiscountAmount();
                   if (!$x || $y>=$x) {
                       break;
                   }
                   $buy = 0; $free = 0;
                   while ($buy+$free<$qty) {
                       $buy += $x;
                       if ($buy+$free>=$qty) {
                           break;
                       }
                       $free += min($y, $qty-$buy-$free);
                       if ($buy+$free>=$qty) {
                           break;
                       }
                   }
                   $discountAmount    = $free*$itemPrice;
                   $baseDiscountAmount= $free*$baseItemPrice;
                   break;

 

someone came up with this solution but only works on the first three products:

 

case 'buy_x_get_y':
                         $cartRules = $address->getCartFixedRules();
                            $x = $rule->getDiscountStep(); //2
                             $y = $rule->getDiscountAmount(); //1

                     if ($quote->getItemsSummaryQty()>=($x+$y)){

                      if (!isset($cartRules[$rule->getId()])) {
                                   $cartRules[$rule->getId()] = $item->getPrice();
                               }elseif($cartRules[$rule->getId()]>$item->getPrice()){
                       $cartRules[$rule->getId()] = $item->getPrice();
                       }


                               if ($cartRules[$rule->getId()] > 0) {
                                   $quoteAmount = $quote->getStore()->convertPrice($cartRules[$rule->getId()]);
                                   $discountAmount = min($item->getRowTotal(), $quoteAmount);
                                   $baseDiscountAmount = min($item->getBaseRowTotal(), $cartRules[$rule->getId()]);
                                   $cartRules[$rule->getId()] -= $baseDiscountAmount;
                               }

                   $address->setCartFixedRules($cartRules);
                   }

                     break;

 

I would appreciate your thoughts on this!
