Question

我是Yii的新手。我正在为用户创建更改密码页面。当我得到验证时，我遇到了麻烦。

这是视图：

<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 -->

型号：

/**
 * @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));
        }
    }
}

我正在使用自定义验证程序“ checkOldPassword ”来检查用户的当前密码。现在的问题是自定义验证无效。此外，如果我关闭javascript 我发现服务器端验证错误也没有显示。我是Yii的新手。所以请原谅任何愚蠢的错误。请帮忙。

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));
        }
    }
}

虽然你的方法还不好...... 但首先让它运作起来......

Answer 2

试试这个：

// 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');
    }
}

将 $ this-＆gt;属性替换为 $ this-＆gt; pwd

首先，我认为clientValidation不起作用，因为您正在检查旧密码，因此您需要服务器端验证（Ajax验证）。 clientValidation有助于检查密码长度等。

所以把这一行： 'enableAjaxValidation'=＆GT;真，

其次，我会将您的代码更改为以下内容：

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");
}
 }
}

Yii自定义验证和服务器端验证？
