afterConstruct()
方法
|
protected void afterConstruct(CEvent $event)
| ||
| $event | CEvent | 事件参数 |
响应 CModel::onAfterConstruct 事件。 Override this method and make it public if you want to handle the corresponding event of the owner.
afterValidate()
方法
|
protected void afterValidate(CEvent $event)
| ||
| $event | CEvent | 事件参数 |
响应 CModel::onAfterValidate 事件。 Override this method and make it public if you want to handle the corresponding event of the owner.
beforeValidate()
方法
|
protected void beforeValidate(CModelEvent $event)
| ||
| $event | CModelEvent | 事件参数 |
响应 CModel::onBeforeValidate 事件。 Override this method and make it public 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). |
源码： framework/base/CModelBehavior.php#29 (显示)
public function events()
{
return array(
'onAfterConstruct'=>'afterConstruct',
'onBeforeValidate'=>'beforeValidate',
'onAfterValidate'=>'afterValidate',
);
}
Declares events and the corresponding event handler methods. The default implementation returns 'onAfterConstruct', 'onBeforeValidate' and 'onAfterValidate' events and handlers. If you override this method, make sure you merge the parent result to the return value.
