当用户注册，系统发送一个确认邮件给用户它的工作很好，但没有任何电子邮件确认系统自动登录或用户可以登录.我该如何解决这个问题，用户应该确认电子邮件登录前，如果用户没有确认一个电子邮件用户不能登录？
我正在使用this project: Yii 2 Advanced Template With Rbac User Managment
我LoginForm模型代码

namespace common\models;
use Yii;
use yii\base\Model;

/**
 * Login form
 */

class LoginForm extends Model
{
public $email;
public $password;
public $rememberMe = true;

protected  $_user = false;

/**
 * @inheritdoc
 */
public function rules()
{
    return [
        // username and password are both required
        ['email', 'filter', 'filter' => 'trim'],
        [['email','password'], 'required'],
        ['email', 'email'],
        // rememberMe must be a boolean value
        ['rememberMe', 'boolean'],
        // password is validated by validatePassword()
        ['password', 'validatePassword','skipOnEmpty'=>false],
    ];
}

/**
 * Validates the password.
 * This method serves as the inline validation for password.
 *
 * @param string $attribute the attribute currently being validated
 * @param array $params the additional name-value pairs given in the rule
 */
public function validatePassword($attribute, $params)
{
    if (!$this->hasErrors()) {
        $user = $this->getUser();
        if (!$user || !$user->validatePassword($this->$attribute)) {
            $this->addError('email', Yii::t('messages','Incorrect password or email.'));
            $this->addError('password', Yii::t('messages','Incorrect password or email.'));
        }
    }
}

/**
 * Logs in a user using the provided username and password.
 *
 * @return boolean whether the user is logged in successfully
 */
public function login()
{
    if ($this->validate()) {
        return Yii::$app->user->login($this->getUser(), $this->rememberMe ? 3600 * 24 * 30 : 0);
    } else {
        return false;
    }
}

/**
 * Finds user by [[username]]
 *
 * @return User|null
 */
public function getUser()
{
    if ($this->_user === false) {
        $this->_user = User::findByEmail($this->email);
    }

    return $this->_user;
}

public function attributeLabels()
{
    return [
        'email' => Yii::t('app','Email'),
        'password' => Yii::t('app','Password')
    ];
}
}
