Check validation rules in Yii framework

Question

I'm new to Yii framework so I'm trying to understand the way it is working. I have the following validation rules for a user creating form, now what I need is to check in afterValidation() method, if all the validation rules have passed an the hash the user password. What I don't know is, if Yii has a build-in method that returns true or false if the validation rules have passed or not.

 public function rules()
    {
        // NOTE: you should only define rules for those attributes that
        // will receive user inputs.
        return array(
            array('email, password, username', 'required'),
            array('email, username, password', 'length', 'max'=>256),
            array('email, username', 'unique'),
            array('password', 'compare'),
            array('password_repeat', 'safe'),
        );
    }




 protected function afterValidate()
        {
            parent::afterValidate();
          if("VALIDATION RULES HAVE PASSED, ther is no error message")
{  
            $this->password = $this->encrypt($this->password);
}
        }
        public function encrypt($value)
        {
          return md5($value);
        }

Answer 1

The method you should be using is $this->hasErrors() since your form validation has already been performed. The likely reason for the nesting error is due to it calling your afterValidate() after each $this->validate() since I would think this is called automatically if validation is performed and you just end up with an infinite loop
