Usage
Below is a very short overview of how to use the extension; the examples folder shows how to implement PBN, looping, forward only navigation, and step timeout in examples of a quiz, survey, and registration.
Attach WizardBehavior to a controller.
The controller contains the event handlers; the two most important events are WizardBehavior::EVENT_WIZARD_STEP and WizardBehavior::EVENT_AFTER_WIZARD, these are responsible for handling the steps of the wizard and processing the data at the end of the wizard respectively.
Controller Action
The controller action is very simple:
WizardBehavior::EVENT_WIZARD_STEP
This event's handler is responsible for validating submitted data and deciding in what direction the Wizard should proceed; this and the data to be stored is placed into the event. When the event is marked as handled by handler the wizard will take the appropriate action.
WizardBehavior::EVENT_AFTER_WIZARD
The handler for this event is responsible for taking the required action once the Wizard has completed; this could be rendering a page based on the user input and/or saving the data to persistant storage.
