Answer 1

Usually, you can use

Yii::app()->user->id

to get the user identity id (from PHP session). The user identity id is usually the id of the user model (set as primary key). Finally, you can get the user model data with it, like

$current_user = User::model()->findByPk(Yii::app()->user->id);
