Hi Scott,

For a number of security reasons you cannot submit the (unit) price for a product in DW when adding it to the cart through a request. You can do ths through the API through, but you need to set the OrderlineType to 2 (Fixed). That will tell DW to not the unit price untouched moving forward.

That makes sense. Do you happen to know the API call (AddToCart() maybe)? It could save some time hunting through the API.

Thank you,

Scott

Also, it looks like everything that sets the OrderLine type is now obsolete according to the API.

There are a few topics on the Forum you can get inspiration from. I find this one interesting enough to get you started

https://doc.dynamicweb.com/forum/development/development/add-orderline-programatically-exception-at-getrewardpoints

This is the code I am using from the above 'inspiration'. However, SetUnitPrice() does not appear to do anything. The price isn't being set when that function call is made so I get the products added to the cart, but they all have price of $0.00.

I'm at a loss here.  

      var Cart = Dynamicweb.eCommerce.Common.Context.Cart ?? new Order();
      Cart.Save();

      
      foreach (var quoteLineItem in quoteLines)
      {
        if (string.IsNullOrWhiteSpace(quoteLineItem.ConfigID__c))
        {
          continue;
        }
        GuruConfiguration gcon = new GuruConfiguration();
        GuruConfigurationRepository gcrepo = new GuruConfigurationRepository();
        gcon = gcrepo.GetById(quoteLineItem.ConfigID__c);

        var guru = GuruHelpers.ConvertCudToFlatObjects(quoteLineItem.CUD_XML__c);
        var data = Boxx.Web.Shared.Guru.GuruExtensions.GetOrderDataFromCud(quoteLineItem.CUD_XML__c);

        
        var line = new OrderLine();
        line.Product = null;
        line.ProductID = gcon.DynamicwebProductId;
        Product thisProduct = Product.GetProductByID(line.ProductID);
        line.ProductNumber = thisProduct.Number;
        line.ProductName = thisProduct.Name;
        line.Quantity = quoteLineItem.Quantity > 0 ? (double)quoteLineItem.Quantity : 0;
        line.AllowOverridePrices = true;
       

        if (data.SystemDiscountPrice == 0)
        {
          line.SetUnitPrice(data.SystemTotalPrice);
        }
        else
        {
          line.SetUnitPrice(data.SystemDiscountPrice);
        }

        line.SetOrderLineType(OrderLine.OrderLineType.Fixed);

        line.Order = Cart;

        Cart.OrderLines.Add(line);
        Cart.ClearCachedPrices();
        Cart.Save();

        
      }
      Dynamicweb.eCommerce.Common.Context.SetCart(Cart);

Also, we have event subscribers for Cart.Created, Cart.Line.Added, Cart.Line.Increased, and Cart.Line.Decreased and none of the above code triggers any of those events (Cart.Created and Cart.Line.Added should be firing at the least, which is why there are two Cart.Save()'s in the code, trying to trigger the events).

Update: Looks like I've gotten something working. The Subscribers still don't fire for some reason, but the cart is created finally.

Hi Scott,

Glad you made some progress. I don't know what might have cause that.

It's the Total Price on an OrderLine. The one that should be the total of {quantity} times {unitprice}. Calculate is set to true, but the total price isn't being calculated, and I haven't found anything as yet in the API that will allow me to set the total price. Is there something I'm missing that should trigger the cart totals to be calculated?

Thank you,

S

Hi Scott,

Looks like you forgot to set the price to be recalculated when you set the UnitPrice

https://doc.dynamicweb.com/api/html/03730260-ebe9-7930-cff5-7c8af1a75e1b.htm

Alternativaly you can try to do this on the cart (instaed of the orderline), but I am not sure if you need to do it before you do the Cart.Save(), or after you set it to the context Dynamicweb.eCommerce.Common.Context.SetCart(Cart); you'll need to try that out.

These don't work. The OrderLineService object that both of the above links use does not exist. If it is an DW9 thing, we don't have DW9.

Thank you
