How to create a checkout flow
This article describes how to create your own checkout flow plugin. Checkout flow plugin contains the business logic for building the order carrier with information such as customer info, deliveries and payment info. In most cases the default implementation is sufficient, but the developer may need to modify to suit it to special requirements.
Default implementation
The default checkout flow plugin is contained in the Litium.Studiodll. It consists of following interfaces. Default implementation of each of these interfaces are contained in Litium.Studio.dll in the namespace Litium.Foundation.Modules.ECommerce.Plugins. The concrete classes are named similar to the interface excluding the prefix 'I'. For example, ICheckoutFlow default implementation concrete class is: Litium.Foundation.Modules.ECommerce.Plugins.Checkout.CheckoutFlow
Creating a custom checkout flow implementation
Best way to create a custom checkout flow implementation is to create a class that inherits from the default implementation, and then override methods that you wish to change.
- Create a new project in Visual Studio, choose appropriate name for the assembly and namespaces.
- Add a dll reference to the default implementation Litium.Studio.dll and to Litium.Foundation.dll
- Inherit your checkoutflow class from default concrete implementation of the respective interface.
- Override the methods you would like to change.
- Copy the .dll file to webroot\bin folder. LitiumStudio automatically detects the customized implementation and uses it replacing the default implementation.
