I need to implement the code, which, depending on the amount of goods of a certain category of repeat purchases and calculates the new price for this product. Dependence is very nonlinear, an example - in the picture in attachment.

I was looking for documentation http://kb.x-cart.com/display/XDD/Definitive+guide and read the forum but could not find any documentation or sample code

Please show me examples or documentation, how to work with a basket of goods and prices in X-CART 5. I really want to understand programming X-CART 5.

Thanks in advance!

Thanks for the question.

Simply put, we need a mod that will work as follows:

first purchase of the customer
- buy 3 products -- one will be free
- buy 6 products -- two will be free

next purchase of the same customer will trigger 10% discount and the bonus products will remain the same:
- buy 3 products -- one will be free
- buy 6 products -- two will be free

Do I understand you properly?

Should this special offer work for all products in the store or for ones from specific category only?

I am planning to create a video tutorial about creating such special-offer-like mods and this mod is a great example, so I probably take this idea and will make a video guide based on it.

Thank you, Tony!

I perfectly understand you, especially because the programmer.
This special offer work for ones from specific category only.

Hi!

I realized that this module is too complex to be a tutorial example, but I have just written a simple implementation of what you need and the pack is here:

Only one update:

To avoid fraud buyer discount - need to calculate the real status of previous orders:

PHP Code:

protected function hasDiscount()
    {
        $discountState = false; 

        $profile = \XLite\Core\Auth::getInstance()->getProfile();
        if ($profile) {
            $cnd = new \XLite\Core\CommonCell();
            $cnd->profile = $profile;
            foreach (\XLite\Core\Database::getRepo('XLite\Model\Order')->search($cnd) as $order) {
                $orderState = $order->getPaymentStatusCode();
                 if ($orderState == \XLite\Model\Order\Status\Payment::STATUS_REFUNDED)
            { $discountState = false; break; }
                if ($orderState == \XLite\Model\Order\Status\Payment::STATUS_PAID)
            $discountState = true;
            }
        }

        return $discountState;
    }

Thanks for the advice! This is exactly what I am doing right now. I hope to finish all basic examples by the end of this month and they will be available here:
