POST Form Handler Implementation
In this video we will configure our Form Handler service using Symfony's standard service definitions. This then allows us to inject the Form Handler into other services that require or depend on it to function properly.
We'll cover a little cheeky tip we can use in Codeception for ensuring your service definitions don't accidentally get changed and break your code in unexpected ways.
With our new services defined, we can go ahead and update our Handler implementation to meet the requirements of the new methods defined on our HandlerInterface.
