Product Custom Fields and Add to Shopping Cart

The site I am building is used for sports program registrations. There is a requirement to capture registrant information (name, age) which I am attempting to do using custom fields in the product as per post #6722. The mechanism captures the information properly and works through to purchase.

The problem is in adding a second copy of the same product (second individual being registered for the same program) to the shopping cart. It is added as a separate item in the shopping cart which means that the volume discount pricing mechanism for the product no longer works. I suspect that this is because of the custom fields.

Is there any simple way to make this work as expected?

Indeed, when you use custom item fields, each entry in the cart is then handled separately from the other which is why you get that result.
What kind of volume discount pricing are you using ? Coupons, discounts or prices with minimum quantities ?

The volume discount mechanism I want to use is prices with minimum quantities. I do not know in advance how many registrants a particular order will have. As an example: families commonly register more than one child but the number of children can vary from season to season depending on what else they are involved in. Families registering can also change season to season. Use of a coupon mechanism to address this volume discount requirement would be logistically challenging.

Note that I do use the coupon mechanism for providing discounts based on previous volunteer work. That works as expected and as desired.

Could you try to replace the code:
foreach($cart->products as $k => $row){
$currencyClass->quantityPrices($cart->products[$k]->prices,@$row->cart_product_quantity,$main_currency);
}

by:
$product_quantities = array();
foreach($cart->products as $row){
$product_quantities[$row->cart_product_id]+=(int)@$row->cart_product_quantity;
}
foreach($cart->products as $k => $row){
$currencyClass->quantityPrices($cart->products[$k]->prices,$product_quantities[$row->cart_product_id],$main_currency);
}

in the file administrator/components/com_hikashop/classes/cart.php ?

I've implemented the suggested change and it doesn't seem to have any effect. The result is still separate entries in the shopping cart if the custom field entries are different. The minimum quantities does work if I enter successive entries where the custom fields are same (ie same name and age) but doesn't if the entries are not successive.

Yes, the entries will still be separated in the cart, BUT the prices should use the global quantity of the product. Isn't that the case ?

The results are mixed. I've tried a number of scenarios in adding the same product (with varying details for first name, last name and age) with results as follows:

    - person 1, person 2, person 3 - all individual details different: separate entries in cart with base price;

    - person 1, person 2, person 3 - person 1 and 2 the same with person 3 different: two entries in cart with first entry reflecting price for ordering quantity of 2 and second entry reflecting free;

    - person 1, person 2, person 3, person 4 - in order with person 1 and 3 the same and person 2 and 4 the same: two entries in cart with first entry reflecting price for ordering quantity of 2 and second entry reflecting free

Could you give us a link to your website with that product page and a FTP access so that we can directly test our modifications there directly and not bother you each time we try something ?

One of the product pages is: www.go-hsa.ca/index.php?option=com_hikas...y_pathway=14&lang=en .

The product is set up with pricing as follows:

    $117CDN with minimum qty of 0
    $100CDN with minimum qty of 2

I have set up an FTP account. Can you give me an email address to which to send it to?

Ah I see, the module cart handles that somewhere else from the main cart.
You need to edit the file components/com_hikashop/views/product/view.html.php and change the code:
foreach($rows as $k => $row){
$currencyClass->quantityPrices($rows[$k]->prices,@$row->cart_product_quantity,$main_currency);
}

to:
$product_quantities = array();
foreach($rows as $row){
if(empty($product_quantities[$row->cart_product_id])){
$product_quantities[$row->cart_product_id] = (int)@$row->cart_product_quantity;
}else{
$product_quantities[$row->cart_product_id]+=(int)@$row->cart_product_quantity;
}
}
foreach($rows as $k => $row){
$currencyClass->quantityPrices($rows[$k]->prices,$product_quantities[$row->cart_product_id],$main_currency);
}

I couldn't do it with your FTP access since yu only gave me access to the back end files of hikashop.

It still doesn't seem to be working. I am getting results similar to the change of the cart.php file (which I have reverted). I have expanded your ftp access so you should now be able to access the front-end files.

Hi,

The problem is fixed now on your website and will be included in next version of HikaShop. There were a bit more modifications to do in other places so that it works properly.
