Yii - 登录后如何防止用户访问登录页面

Question

everyone. I want to prevent user accessing login page after they have logged in. What is the best way to do that? Here's the code of config/main/php

return array(
'basePath'=>dirname(__FILE__).DIRECTORY_SEPARATOR.'..',
'name'=>'My Web',
'defaultController' => 'site/login')

And SiteContoller.php

public function actionLogin()
{
    $model=new LoginForm;

    // if it is ajax validation request
    if(isset($_POST['ajax']) && $_POST['ajax']==='login-form')
    {
        echo CActiveForm::validate($model);
        Yii::app()->end();
    }

    // collect user input data
    if(isset($_POST['LoginForm']))
    {
        $model->attributes=$_POST['LoginForm'];
        // validate user input and redirect to the previous page if valid
        if($model->validate() && $model->login()){
            $isAdmin = Yii::app()->user->getLevel() <=1; // or how you define admin in your case.
            if ($isAdmin)
                $this->redirect(array('user/view', 'id'=>Yii::app()->user->id));
            else
            //$id = Yii::app()->user->id;
                $this->redirect(array('site/index'));
        }
    }
    // display the login form
    $this->render('login',array('model'=>$model));
}

In 'defaultController'=>'site/login' I also want user not accessing login page after they close brower and reopen it. Is that possible? Thanks a lot

You can try this way, its simple .

public function actionLogin()
{

   if(!Yii::app()->user->isGuest)
   {
       $this->redirect(array('index')); 
   }

   // rest of the codebelow.

}
