yii, some form validation examples

Yii some basic form validations using rules in models
like email, compare password (match password), date, unique, captcha etc

Below is full model code:

<?php

 *
 * The followings are the available columns in table 'users':
 * @property integer $user_id
 * @property string $user_name
 * @property string $user_password
 * @property string $user_email
 * @property string $user_gender
 * @property integer $user_age
 * @property string $user_location
 * @property string $user_avatar
 * @property string $user_facebook_id
 * @property integer $user_receive_newsletters_flag
 * @property integer $is_admin
