This little tutorial explains a way how you can retrieve more parameters from **Yii::app()->user** by adding a component that extends **CWebUser** and retrieves the user information from database table named User. There is also another method of doing this that retrieves the variables from session or cookie instead: [How to add more information to Yii::app()->user (based on session or cookie)](http://www.yiiframework.com/doc/cookbook/6/)

**Steps to follow:**
1. Make shure you have got an database User model.
2. Create a component that extends CWebUser.
3. Specify in the config.php what user class the application must use.
