afterValidate()
方法
|
public void afterValidate(CEvent $event)
| ||
| $event | CEvent | event parameter |
Responds to CModel::onAfterValidate event. Overrides this method if you want to handle the corresponding event of the owner.
beforeValidate()
方法
|
public void beforeValidate(CModelEvent $event)
| ||
| $event | CModelEvent | event parameter |
Responds to CModel::onBeforeValidate event. Overrides this method if you want to handle the corresponding event of the owner. You may set CModelEvent::isValid to be false to quit the validation process.
events()
方法
|
public array events()
| ||
| {return} | array | events (array keys) and the corresponding event handler methods (array values). |
Declares events and the corresponding event handler methods. The default implementation returns 'onBeforeValidate' and 'onAfterValidate' events and handlers. If you override this method, make sure you merge the parent result to the return value.
