Method Details

afterConstruct() method
protected void afterConstruct(CEvent $event)
$event CEvent event parameter
Source Code: framework/base/CModelBehavior.php#44 (show)
protected function afterConstruct($event)
{
}

Responds to CModel::onAfterConstruct event. Override this method and make it public if you want to handle the corresponding event of the owner.

afterValidate() method
protected void afterValidate(CEvent $event)
$event CEvent event parameter
Source Code: framework/base/CModelBehavior.php#65 (show)
protected function afterValidate($event)
{
}

Responds to CModel::onAfterValidate event. Override this method and make it public if you want to handle the corresponding event of the owner.

beforeValidate() method
protected void beforeValidate(CModelEvent $event)
$event CModelEvent event parameter
Source Code: framework/base/CModelBehavior.php#55 (show)
protected function beforeValidate($event)
{
}

Responds to CModel::onBeforeValidate event. 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() method
public array events()
{return} array events (array keys) and the corresponding event handler methods (array values).
Source Code: framework/base/CModelBehavior.php#29 (show)
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.
