Discount based on other products in cart

I want to alter the price for products in the cart (ProductPriceForQuantity) based on other products in the cart (coupons or discounts do not work for me here) but:

onBeforeCalculateProductPriceForQuantity(&$product)
and
function onAfterCalculateProductPriceForQuantity(&$product)
do not include the cart information,

onAfterCartProductsLoad is too late.

the added „hikashop_product_price_for_quantity_in_cart“ function at the bottom of the „currency.php“ did not work, because inside the class it won’t be triggered, and outside I have no access to the class itself (or better I don’t know how). And the „custom_quantity_tax“ plugin seems to override as it also contains the function. By the way, is it really the correct way to add the function to the file “currency.php”. What about Hika-Updates? Or did I misunderstood the documentation?

Do you have any hint for me?

Cheers,
Ralf

Thanks,

maybe, this would be helpful for others:


function onAfterCalculateProductPriceForQuantity(&$product) {
$pc=$product->product_code;
$pctid=substr($pc,7,1);
if ($pctid=="B") {
$pcid=substr($pc, 0, 7);//family
$pcfid=substr($pc,-4);//style pack

$class = hikashop_get('class.cart');
if(!empty($product->cart_id)) {
$element = $class->get($product->cart_id,true,$product->cart_type);
foreach($element as &$value)
if ($value->product_code != $pc && substr($value->product_code,7,1)=="A" && substr($value->product_code,-4)==$pcfid) {
$product->prices[0]->price_value=$product->prices[0]->price_value*50/100;
}
}
}
}

A little extension:

I need to visualize the discounted price.
Is it possible to use any unused variable in the $product parameter of onAfterCalculateProductPriceForQuantity(&$product) or to create a new one?
Or do you have any other hint?

Many Cheers,
Ralf

Hi,

Sure I think that you can do it if the variable is not used, but can you tell me exactly where do you want to visualize your discounted price, with a screenshot for example ?

Thanks .

pos 3 is discounted, because the "connected" pos 2 is also in cart. And the discount should be more visible for the buyer

Cheers,

yes, but I wanted to calculate the price based on other products in the cart, this was only possible in "onAfterCalculateProductPriceForQuantity(&$product) ".
And now I want to visualize the calculation to the user, which is only possible on the "listing_price", I think.
So how can I get a connection?

Cheers,
Ralf
