Yii2 - 自定義功能獨特的電子郵件

Question

內規則方法我有這樣的規則，電子郵件：

['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".'); 
    } 

電子郵件驗證工作，但uniqueEmail是不工作。我怎樣才能做到這一點？

Answer 1

爲什麼你認爲$email與填充該值？作爲由文檔所述，第二函數參數是實際參數陣列，在驗證器聲明（['email', 'uninqueEmail', 'param1' => 'value1', 'param2', 'value2'])

的端部供給的嘗試這種情況：

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它接受申報的ad-hoc審定匿名函數：

['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'],
