class TestController extends CController
{
    function actionOk()
    {
        Yii::app()->user->setFlash('success', 'Everything went fine!');
        $this->redirect('index');
    }
    function actionBad()
    {
        Yii::app()->user->setFlash('error', 'Everything went wrong!');
        $this->redirect('index');
    }
    function actionIndex()
    {
        $this->render('index');
    }
}
 
在protected/views/test创建index.php文件：
<?php if(Yii::app()->user->hasFlash('success')):?>
    <div class="flash-notice">
    <?php echo Yii::app()->user->getFlash('success')?>
    </div>
<?php endif?>
 
<?php if(Yii::app()->user->hasFlash('error')):?>
    <div class="flash-error">
    <?php echo Yii::app()->user->getFlash('error')?>
    </div>
<?php endif?>
