Yii自定義驗證和服務器端驗證？

Question

我是Yii的新手。我正在爲用戶進行更改密碼頁面。當我得到驗證時，我遇到了麻煩。

這是視圖：

<div class="form"> 
<?php $form=$this->beginWidget('CActiveForm', array(
    'id'=>'changepassword-form', 
    'enableClientValidation'=>true, 
    'clientOptions'=>array(
    'validateOnSubmit'=>true, 
    ), 
)); ?> 

<p class="note">Fields with <span class="required">*</span> are required.</p> 
<?php echo $form->errorSummary($model); ?> 
<div class="row"> 
    <?php echo $form->labelEx($model,'old_pwd'); ?> 
    <?php echo $form->textField($model,'old_pwd'); ?> 
    <?php echo $form->error($model,'old_pwd'); ?> 
</div> 

<div class="row"> 
    <?php echo $form->labelEx($model,'pwd'); ?> 
    <?php echo $form->textField($model,'pwd'); ?> 
    <?php echo $form->error($model,'pwd'); ?> 
</div> 

<div class="row"> 
    <?php echo $form->labelEx($model,'pwd_repeat'); ?> 
    <?php echo $form->passwordField($model, 'pwd_repeat'); ?> 
    <?php echo $form->error($model,'pwd_repeat'); ?> 
    <p class="hint"> 
     Passwords must be minimum 6 characters and can contain alphabets, numbers and special characters. 
    </p> 
</div> 


<div class="row buttons"> 
    <?php echo CHtml::submitButton('Change Password'); ?> 
</div> 

<?php $this->endWidget(); ?> 
</div><!-- form --> 

型號：

/** 
* @return array validation rules for model attributes. 
*/ 
public function rules() 
{ 
    // NOTE: you should only define rules for those attributes that 
    // will receive user inputs. 
    return array(
     array('user, pwd, status, old_pwd, pwd_repeat', 'required'), 
     array('user', 'length', 'max'=>50), 
     array('pwd', 'length', 'max'=>30), 
     array('status', 'length', 'max'=>10), 
     array('pwd','compare'), 
     array('old_pwd','checkOldPassword'), 
     // The following rule is used by search(). 
     // Please remove those attributes that should not be searched. 
     array('id, user, pwd, status', 'safe', 'on'=>'search'), 
    ); 
} 

// FOR CHECKING IF THE PASSWORD IS VALID 
public function checkOldPassword($attribute,$params) 
{ 
    $record=Admin::model()->findByAttributes(array('pwd'=>$this->attribute)); 

    if($record===null){ 
     $this->addError($attribute, 'Invalid password'); 
    } 
} 

控制器：

/** 
* Change Password for users 
*/ 
public function actionChangePassword() 
{ 
    // renders the view file 'protected/views/site/index.php' 
    // using the default layout 'protected/views/layouts/main.php' 
    if(Yii::app()->user->isGuest){ 
     // If the user is guest or not logged in redirect to the login form 
     $this->redirect(array('site/login')); 
    } 
    else{ 
     $model = new Admin; 
     if(isset($_POST['Admin'])){ 

      $model->attributes=$_POST['Admin']; 

      $this->render('changepassword',array('model'=>$model)); 
     } 
     else{ 
      $this->render('changepassword',array('model'=>$model)); 
     } 
    } 
} 

我使用自定義驗證器'checkOldPassword'用於檢查用戶的當前密碼。現在的問題是，自定義驗證不起作用。此外，如果我關閉javascript 我發現服務器端驗證錯誤也不顯示。 Iam是Yii的新人。所以請原諒任何愚蠢的錯誤。 請幫忙。

public function rules() 
{ 
    // NOTE: you should only define rules for those attributes that 
    // will receive user inputs. 
    public $pwd_repeat; 
    public $old_pwd; 

    return array(
    array('old_pwd,pwd_repeat,pwd','safe'), 
     array('user, pwd, status, old_pwd, pwd_repeat', 'required'), 
     array('user', 'length', 'max'=>50), 
     array('pwd', 'length', 'max'=>30), 
     array('status', 'length', 'max'=>10), 
     array('pwd','compare'), 
     array('old_pwd','checkOldPassword'), 
     // The following rule is used by search(). 
     // Please remove those attributes that should not be searched. 
     array('id, user, pwd, status', 'safe', 'on'=>'search'), 
    ); 
} 

// FOR CHECKING IF THE PASSWORD IS VALID 
public function checkOldPassword($attribute,$params) 
{ 
    $record=Admin::model()->findByAttributes(array('pwd'=>$this->attributes['old_pwd'])); 

    if($record===null){ 
     $this->addError($attribute, 'Invalid password'); 
    } 
} 

public function actionChangePassword() 
{ 
    // renders the view file 'protected/views/site/index.php' 
    // using the default layout 'protected/views/layouts/main.php' 
    if(Yii::app()->user->isGuest){ 
     // If the user is guest or not logged in redirect to the login form 
     $this->redirect(array('site/login')); 
    } 
    else{ 
     $model = new Admin; 
     if(isset($_POST['Admin'])){ 

      $model->attributes=$_POST['Admin']; 
      $model->save(); 
      $this->render('changepassword',array('model'=>$model)); 
     } 
     else{ 
      $this->render('changepassword',array('model'=>$model)); 
     } 
    } 
} 

雖仍您的計算策略是不好的...... 但是首先讓它工作..

試試這個：

// FOR CHECKING IF THE PASSWORD IS VALID 
public function checkOldPassword($attribute,$params) 
{ 
    $record=Admin::model()->findByAttributes(array('pwd'=>$this->pwd)); 

    if($record===null){ 
     $this->addError($attribute, 'Invalid password'); 
    } 
} 

更換$這個 - >屬性至$這個 - > PWD

首先我相信clientValidation將不起作用，因爲您正在檢查舊密碼，因此您需要服務器端驗證（Ajax驗證）。 clientValidation便於檢查密碼長度等

所以就把這條線： 「enableAjaxValidation」 =>真實，

其次，我會更改您的代碼是這樣的：

public function checkOldPassword($attribute,$params) 
{ 
    $record = $this->find(array(
       'select' => 'old_password', 
       'condition' => 'username=:username', 
       'params' => array(':username' => $username//or user or w/e ur gonna find user), 
        )); 

if($record===null){ 
    $this->addError($attribute, 'Invalid password'); 
} 
else { 

if($this->old_password != $record->old_password) { 

$this->addError('old_password', "Invalid Password"); 
} 
} 
}
