如何使更新頁面中的密碼字段爲空yii2

Question

您好，我正在Yii2項目上工作。我有用戶模塊，在更新任何用戶的同時，輸入的密碼是用原來的密碼來的。我想在更新頁面上使密碼字段爲空。

我正在使用密碼哈希，但在更新頁面密碼來與其原始值，我試圖null，提交但運氣不好。

我想：

<?= $form->field($model, 'password_hash')->passwordInput(['maxlength' => true,'value'=>null]) ?> 

即使我嘗試 $model->password_hash=""的控制器，但沒有發生。

但是沒有發生任何密碼字段與它的價值。

這是我的用戶模型規則：

public function rules() { 
     return [ 
      [['first_name', 'last_name', 'address', 'mobile', 'email', 'password_hash', 'role_id'], 'required'], 
      [['address'], 'string'], 
      [['role_id'], 'integer'], 
      [['email'], 'email'], 
      [['email'], 'unique', 'targetAttribute' => ['email']], 
      [['created_at', 'updated_at'], 'safe'], 
      [['first_name', 'last_name', 'email', 'password_hash'], 'string', 'max' => 255], 
      [['mobile'], 'required','on'=>'create,update'], 
      //[['mobile'], 'string','max'=>10], 
      [['mobile'], 'number','numberPattern' => '/^[0-9]{10}$/','message'=>"Mobile must be integer and should not greater then 10 digit"], 
      [['password_hash'],'string','min'=>6], 
      //[['mobile'], 'number'], 
      [['status'], 'string', 'max' => 1,'on'=>'create,update'], 
      [['role_id'], 'exist', 'skipOnError' => true, 'targetClass' => Roles::className(), 'targetAttribute' => ['role_id' => 'id']], 
     ]; 
    } 

用戶控制器：

public function actionUpdate($id) 
    { 
     $model = $this->findModel($id); 
     $roles= Roles::find()->all(); 
     $model->password_hash=""; 
     if ($model->load(Yii::$app->request->post())) { 
      $input=Yii::$app->request->post(); 
      if($input['Users']['password_hash']!=""){ 
       $model->password_hash=User::setPassword($model->password_hash); 
      } 
      //$model->auth_key=User::generateAuthKey(); 
      $model->status=$input['Users']['status']; 
      unset($model->created_at); 
      $model->updated_at=date('Y-m-d H:i:s'); 
       //echo "<pre>";print_r($model);exit; 

      $model->save(); 
      Yii::$app->session->setFlash('success', "Record has been updated successfully !"); 
      //return $this->redirect(['view', 'id' => $model->id]); 
      return $this->redirect(['index']); 
     } else { 
      return $this->render('update', [ 
       'model' => $model, 
       'roles'=>$roles 
      ]); 
     } 
    } 

用戶表單：

<?php $form = ActiveForm::begin(); ?> 
    <div class="row"> 
     <div class="col-md-4"> 
      <?= $form->field($model, 'first_name')->textInput(['maxlength' => true]) ?> 
     </div> 
     <div class="col-md-4"> 
      <?= $form->field($model, 'last_name')->textInput(['maxlength' => true]) ?> 
     </div> 
    </div> 
    <div class="row"> 
     <div class="col-md-8"> 
      <?= $form->field($model, 'address')->textarea(['rows' => 6]) ?> 
     </div> 
    </div> 
    <div class="row"> 
     <div class="col-md-4"> 
      <?= $form->field($model, 'mobile')->textInput(['maxlength' => true]) ?> 
     </div> 
    </div> 
    <div class="row"> 
     <div class="col-md-4"> 
      <?= $form->field($model, 'email')->textInput(['maxlength' => true]) ?> 
     </div> 
     <div class="col-md-4"> 
      <?= $form->field($model, 'password_hash')->passwordInput(['maxlength' => true,'value'=>""]) ?> 
     </div> 
    </div> 
    <div class="row"> 
     <div class="col-md-4"> 
      <?= $form->field($model, 'status')->dropDownList(['0'=>'Active','1'=>'InActive']); ?> 
     </div> 

     <div class="col-md-4"> 
      <?= $form->field($model, 'role_id')->dropDownList(ArrayHelper::map(Roles::find()->all(),'id','name')) ?> 
     </div> 
    </div> 

    <div class="form-group"> 
     <?= Html::submitButton($model->isNewRecord ? 'Create' : 'Update', ['class' => 'btn green']) ?> 
     <?= Html::a('Cancel', ['/ag-consumer'], ['class' => 'btn default']) ?> 
    </div> 

    <?php ActiveForm::end(); ?> 

Answer 1

爲什麼不在更新時刪除它？

像這樣：

<?= $model->isNewRecord ? $form->field($model, 'password_hash')->passwordInput(['maxlength' => true]) : "" ?> 

快樂編碼。 :)

UPDATE

如果密碼字段是真正需要的是有，那就試試這個在控制器：

public function actionUpdate($id) 
{ 
    $model = $this->findModel($id); 
    $password = $model->password_hash; // backup the value first; 
    $model->password_hash = ""; 

    if ($model->load(Yii::$app->request->post()) && $model->save()) { 
     $model->password_hash = $password; // retreive the value back 
     $model->save(); 
     // redirect here 
    } 
    return $this->render('update', [ 
     'model' => $model, 
    ]); 
} 

Answer 2

不採取password_hash。你必須在模型如密碼來創建新的變量

public $password; 
public function rules() { 
      return [ 
       [['first_name', 'last_name', 'address', 'mobile', 'email', 'password', 'role_id'], 'required'], 
       [['address'], 'string'], 
       [['role_id'], 'integer'], 
       [['email'], 'email'], 
       [['email'], 'unique', 'targetAttribute' => ['email']], 
       [['created_at', 'updated_at'], 'safe'], 
       [['first_name', 'last_name', 'email', 'password'], 'string', 'max' => 255], 
       [['mobile'], 'required','on'=>'create,update'], 
       //[['mobile'], 'string','max'=>10], 
       [['mobile'], 'number','numberPattern' => '/^[0-9]{10}$/','message'=>"Mobile must be integer and should not greater then 10 digit"], 
       [['password'],'string','min'=>6], 
       //[['mobile'], 'number'], 
       [['status'], 'string', 'max' => 1,'on'=>'create,update'], 
       [['role_id'], 'exist', 'skipOnError' => true, 'targetClass' => Roles::className(), 'targetAttribute' => ['role_id' => 'id']], 
      ]; 
     } 

查看

<?= $form->field($model, 'password')->passwordInput(['maxlength' => true,'value'=>null]) ?> 

型號或的Controler例如

if ($this->validate()) { 
     $user = User::findOne($id); 
     $user->setPassword($this->password); 
     $user->generateAuthKey(); 
     $user->save(false); 
}
