|
* Optional controller for every widget which has its own logic, e.g. in forms. |
|
12
|
|
|
* |
|
13
|
|
|
* It always handles a single widget, usually passed in as a database |
|
14
|
|
|
* identifier through the controller URL. Needs to be constructed as a nested |
|
15
|
|
|
* controller within a {@link ContentController}. |
|
16
|
|
|
* |
|
17
|
|
|
* ## Forms |
|
18
|
|
|
* You can add forms like in any other SilverStripe controller. If you need |
|
19
|
|
|
* access to the widget from within a form, you can use |
|
20
|
|
|
* `$this->controller->getWidget()` inside the form logic. |
|
21
|
|
|
* |
|
22
|
|
|
* Note: Widget controllers currently only work on {@link Page} objects, |
|
23
|
|
|
* because the logic is implemented in {@link ContentController->handleWidget()}. |
|
24
|
|
|
* Copy this logic and the URL rules to enable it for other controllers. |
