Question

内部规则方法我有电子邮件规则：

['email', 'uniqueEmail'],
['email', 'email'],

和uniqueEmail方法：

public function uniqueEmail($attribute, $email)
    {
        $user = static::findOne(['email' => Yii::$app->encrypter->encrypt($email)]);
        if (count($user) > 0)
            $this->addError($attribute, 'This email is already in use".');
    }

电子邮件验证工作正常，但 uniqueEmail 无效。我怎样才能做到这一点？

为什么您认为$email填充了该值？正如文档所述，第二个函数参数实际上是参数数组，在验证器声明的末尾提供（['email', 'uninqueEmail', 'param1' => 'value1', 'param2', 'value2'])

试试这个：

public function uniqueEmail($attribute) {
    $user = static::findOne(['email' => Yii::$app->encrypter->encrypt($this->{$attribute})]);
    if ($user) { // dont use count($user) - if it's there, it's a single object, you want to check if it's not null!
        $this->addError($attribute, 'This email is already in use".');
    }
}

在Yii2中，接受将ad-hoc验证声明为匿名函数：

['email', function($attribute) {
    $user = static::findOne(['email' => Yii::$app->encrypter->encrypt($this->{$attribute})]);
    if ($user) {
        $this->addError($attribute, 'This email is already in use".');
    }
}],
['email', 'email'],
