/**
|
|
* Optional controller for every widget which has its own logic, e.g. in forms.
|
|
*
|
|
* It always handles a single widget, usually passed in as a database
|
|
* identifier through the controller URL. Needs to be constructed as a nested
|
|
* controller within a {@link ContentController}.
|
|
*
|
|
* ## Forms
|
|
* You can add forms like in any other SilverStripe controller. If you need
|
|
* access to the widget from within a form, you can use
|
|
* `$this->controller->getWidget()` inside the form logic.
|
|
*
|
|
* Note: Widget controllers currently only work on {@link Page} objects,
|
|
* because the logic is implemented in {@link ContentController->handleWidget()}.
|
|
* Copy this logic and the URL rules to enable it for other controllers.
