使用yii框架注册时遇到麻烦

Question

I'm trying to implement user registration using yii ActiveRecord. the problem is that every time the view is being loaded i get the following exception:

User has an invalid validation rule. 
The rule must specify attributes to be validated and the validator name. 

here is the relevant part from the Users model:

public function rules()
{
    // NOTE: you should only define rules for those attributes that
    // will receive user inputs.
    return array(
        array('username, password,verifyCode,email','message'=>'Tidak boleh kosong'),
            //array('password','compare'),
            array('verifyCode', 'captcha', 'required', 'allowEmpty'=>!extension_loaded('gd')),
            array('level_id', 'numerical', 'integerOnly'=>true),
            array('username', 'length', 'max'=>20),
            array('password, email', 'length', 'max'=>50),
            //array('password_repeat','required'),
            array('avatar', 'file', 'types'=>'gif,png,jpg'),
            // The following rule is used by search().
            // @todo Please remove those attributes that should not be searched.
            array('id, username, password, email, joinDate, level_id, avatar', 'safe', 'on'=>'search'),
    );
}

Controller:

public function actionRegister() {
    $registration = new RegistrationForm("register");
    // collect user input data
    if (isset($_POST['RegistrationForm'])) {
        $registration->attributes = $_POST['RegistrationForm'];
        $registration->attributes = $_POST['RegistrationForm'];
        // validate user input and redirect to the previous page if valid
        if ($registration->validate()) {
            // create an account model
            $account = new User;
            $account->username = $registration->username;
            $account->password = $registration->password;
            $account->email = $registration->email;
            $account->joinDate = new CDbExpression('NOW()');
            //$account->level_id = 1;
            if ($account->save()) {
                $member = new Member;
                $member->attributes = $registration->attributes;
                $member->user_id = $account->id;
                if ($member->save()) { 
                    $this->redirect(array('index'));
                } else {
                    $registration->addErrors($member->getErrors());
                }
            } else {
                $registration->addErrors($account->getErrors());
            }
        }
    }
    $this->render('register', array('model' => $registration));
}

This is because you missed a validator in your first rule. As I think, you missed the required validator.

So you need to change this:

array('username, password,verifyCode,email','message'=>'Tidak boleh kosong'),

To something like this:

array('username, password,verifyCode,email','required','message'=>'Tidak boleh kosong'),

Another mistake is, that your using the captcha validator . Captcha can only be used in a view with a CFormModel , a CCaptcha Widget and a CCaptcha action .

If you want a file upload, that isn't required, you need to add the allowEmpty :

array('avatar', 'file', 'allowEmpty' => true, 'types'=>'gif,png,jpg'),
