Modifying the admin interface

Create your own custom module. There you can create your own webparts and/or templates and display them in the UI.

Yes, if you place the buy X get Y web part on the shopping cart page it's smart enough, if you don't, I don't believe it is.

Thanks Brenden, I hope you don't mind me asking a couple of further questions?

I have established that the shopping cart IS clever enough to apply discounts automatically, so if you have a Buy X Get Y discount without a coupon in place, it will apply automatically.

Additionally, you can get these discounts back from the cart using:

ShoppingCart.OrderRelatedDiscountSummaryItems

So that's great! However, I cannot see a Buy X Get Y web part anywhere? Also, when creating a custom module, I'd really just like to have the current BUY X Get Y interface but just customizing what comes back in the product selector. I got as far as getting to: Modules > E-commerce > User Interface > New Buy X Get Y discount > Design > but then from here, where do I create the new custom module?

Thanks again for your help!

Hello Gabor,

The name displayed is determined by macro. So the easiest solution to write a simple Custom Macro Method, to which you will pass the SKUID and SKUParentSKUID, and which will return a string composed of the SKUNames of the Parent and Variant. You will then enter this macro to:

Development -> Modules -> E-commerce -> Classes -> Multibuy discount -> Alternative forms -> GeneralBuyOneGetOne -> BuyProductSet -> Advanced -> Display name format

Thank you Josef,

This seems like exactly what I was looking for.

I have made some headway on this, but I'm really struggling on passing the SKU ID through to the macro. Hereis my macro code:

[assembly: RegisterExtension(typeof(SKUVariantMacros), typeof(SystemNamespace))]
public class SKUVariantMacros : MacroMethodContainer
{

    [MacroMethod(typeof(string), "Gets the fully qualified name of the variant", 1)]
    [MacroMethodParam(0, "param1", typeof(int), "The ID of the variant SKU")]
    public static object GetSkuParentVariantName(EvaluationContext context, params object[] parameters)
    {
        var skuID = ValidationHelper.GetInteger(parameters[0], 0);
        var variant = VariantHelper.GetVariantById(skuID);
        if (variant == null)
        {
            var skuInfo = SkuHelper.GetSKUById(skuID);
            if (skuInfo != null) return skuInfo.SKUName;
            else return "";
        }
        return variant.ProductName + " - " + variant.VariantName;
    }
}

And then this is how I'm calling it:

{%GetSkuParentVariantName(SKUID)%}

I have opened the extended field editor using the little arrow next to: Display name format, as without this, it wasn't working. I was getting a db error.

Can you tell me what I'm doing wrong?

Regards, Gabor
