You can create your own controllers which extend from the current ones - in this case, I have an extension controller for the basket form which reads as:

@Html.Action("BasketForm", "StoreBasketExtend")

It uses all the existing models, but with this I've copied the existing logic from Merchello and then added in some bespoke code I need. You can do the same thing for adding products to your basket, applying coupons etc.

Hope this helps!

Thanks for your reply! We extended the basket controller and it works fine right now.

An other question: Right now i'm using Fastrack for rendering the Checkout (fine for now), but got an error on using this reference: Merchello.FastTrack.Ui

I've builded my project (and the models, Models namespace is Umbraco.Web.PublishedContentModels)

Do I need to change someting, for example I can't use: ExampleUiHelper?

Also; I saw that the checkout is devided into serveral pages, could we also make this as one page (do you have an axample of what to change).

It's been a while, but I'm sure I stripped out all references to ExampleUiHelper as they were also throwing errors for me.

In terms of having a one page checkout, I can tell you from experience it's not easy - it's doable, but you are making a lot of changes to Merchello to get it up and running. An issue I ran into was creating a "fake" (or blank) Invoice at the start of the process, when this can normally only be created once shipping details have been entered (someone may correct me here with a nice workaround!).

It would be easier to create it as a multi-stage checkout and loading the next section through Ajax.

Currently in my ResolvePayment.cshtml I have added the following line:

case "Mollie": @Html.Action("PaymentForm", "Mollie", new { area = "FastTrack", view = "~/Views/Merchello/Checkout/Mollie/PaymentForm.cshtml" }) break;

The websites gives me the folowing error:

No route in the route table matches the supplied values.

My logic:

[GatewayMethodUi("Mollie")]
public class MolliePaymentGatewayMethod : PaymentGatewayMethodBase
{

And:

  [GatewayProviderActivation("f8fa58d9-2c0d-4e07-aaac-e0f86f5b614a", "Mollie Payment Provider", "Mollie Payment Providor")]
        public class MolliePaymentGatewayProvider : PaymentGatewayProviderBase, IPurchaseOrderPaymentGatewayProvider

And the view that i would like to render:

@inherits Umbraco.Web.Mvc.UmbracoViewPage<Mollie.PaymentProviders.MolliePaymentModel>
@using System.Web.Mvc.Html
@using Mollie.Payment;
@using Umbraco.Web
@{
    var umbHelper = new UmbracoHelper(HttpContext.Current.GetUmbracoContext());

    string invoiceUrl = umbHelper.TypedContentAtRoot().DescendantsOrSelf<Checkout>().Where(n => n.TemplateId == 1206).Count() > 0 ? umbHelper.TypedContentAtRoot().DescendantsOrSelf<Checkout>().Where(n => n.TemplateId == 1206).FirstOrDefault().Url : null;
    Model.SuccessRedirectUrl = invoiceUrl;
    @* todo: check where! *@
    string paymentMethodUrl = umbHelper.TypedContentAtRoot().DescendantsOrSelf<Checkout>().Where(n => n.TemplateId == 1126).Count() > 0 ? umbHelper.TypedContentAtRoot().DescendantsOrSelf<Checkout>().Where(n => n.TemplateId == 1126).FirstOrDefault().Url : null;
}
@* todo *@
<h3>Betallen</h3>
@using (Html.BeginUmbracoForm<MolliePaymentController>("Process", new { area = "FastTrack" }))
{
    @Html.AntiForgeryToken()
    @Html.HiddenFor(x => x.SuccessRedirectUrl)

    <a href="@paymentMethodUrl" class="btn btn-default">Terug</a>
    <input type="submit" class="btn btn-default pull-right" value="Betalen" />

}

What is missing? Tried the Name 'Mollie', 'MolliePayment' inside my html.Action.

Runnic,

Try without the area = "FastTrack", in your action. That is reserved for action methods decorated with an area attribute of "FastTrack", so they can be separated from other Plugins and custom code.

If you have writting your own Action Method in the MolliePaymentController you should not need to specify area at all (or possible area = "")

is working on a reply...
