Password Validation In Yii Model

From my sourcecode, I gave the information for password validation in yii framework. I used password and confirm password validation.


<?php
class User extends CActiveRecord
{
    public static function model($className=__CLASS__)
    {
        return parent::model($className);
    }
	
    public function tableName()
    {
        return 'tbl_user';
    }
	
    public function rules()
    {
        array('password', 'compare', 
            'compareAttribute' => 'confirmpassword',
            'on'=>'insert' 
        ),
    }
}
?>
