How do you add products to the basket ? 

public string AddProduct(string productid, string quantity)
        {
            int nrofproducts = 0;

            try {
                Basket basket = basket = SiteContext.Current.OrderContext.GetBasket();

                if (basket != null) {
                    Product product = Product.All().Single(x => x.Sku == productid);

                    bool emptyPrices = product.PriceGroupPrices.Where(p => p.Price <= 0).Any();
                    if (!emptyPrices) {
                        PurchaseOrder order = basket.PurchaseOrder;
                        PriceGroup pricegroup = SiteContext.Current.CatalogContext.CurrentCatalog.PriceGroup;
                        order.AddProduct(pricegroup, product, Convert.ToInt16(quantity));

                        // Exec basket pipeline to update totals
                        UCommerce.Xslt.Library.ExecuteBasketPipeline();
                    }

                    foreach (OrderLine orderl in basket.PurchaseOrder.OrderLines) {
                        nrofproducts += orderl.Quantity;
                    }
                } else {
                    ExceptionHelper.LogException("Unable to retrieve shopping basket from site-context!");
                }
            }
            catch (Exception ex) {
                ExceptionHelper.LogException(ex, "Error in webservice AddProduct");
            }

            return nrofproducts.ToString();
        }

Hi Wouter, 

You should use TransactionLibrary.AddToBasket. It will do all the magic for you. 

You can easily just send ind a productId but you can also run on currentproduct if you do this on a product page:

SiteContext.Current.CatalogContext.CurrentProduct 

I might be missing some context though. Can you elaborate a little bit of what you're trying to achieve here? 

At the end of the method you can return order.OrderLines.Sum(x => x.Quantity); which will give you the total amount rather that doing a foreach :) 

Try refactoring the code and let me know if this solves the problem.

Hope this helps. 

Regards

Morten

Thank you for your reply. TransactionLibrary.AddToBasket does not seem to work though, the numers are still zero. I guess I made a mistake somewhere else. I'll dig into it and if I find why I'll post it here.

Did you comment out the pipeline methods in the basket pipeline configuration file?

When you use SiteContext.Current.CatalogContext.CurrentPriceGroup; then what is the VAT rate on that? What is configured on the catalog related to pricegroup and VAT? 

is working on a reply...
