• Yii 设置 flash消息 创建一个渐隐形式的消息框


     1 /*适用情况:比如提交一个表单,提交完成之后在页面展示一条提示消息。
     2 控制器里面这样写:
     3 单条消息:
     4 */
     5 Yii::$app->getSession()->setFlash('error', 'This is the message');
     6 
     7 Yii::$app->getSession()->setFlash('success', 'This is the message');
     8 
     9 Yii::$app->getSession()->setFlash('info', 'This is the message');
    10 #多条消息:
    11 Yii::$app->getSession()->setFlash('error', ['Error 1', 'Error 2']);
    12 
    13 #然后是视图里面:
    14 
    15 先引入Alert:use yiiootstrapAlert;
    16 if( Yii::$app->getSession()->hasFlash('success') ) {
    17     echo Alert::widget([
    18         'options' => [
    19             'class' => 'alert-success', //这里是提示框的class
    20         ],
    21         'body' => Yii::$app->getSession()->getFlash('success'), //消息体
    22     ]);
    23 }
    24 if( Yii::$app->getSession()->hasFlash('error') ) {
    25     echo Alert::widget([
    26         'options' => [
    27             'class' => 'alert-error',
    28         ],
    29         'body' => Yii::$app->getSession()->getFlash('error'),
    30     ]);
    31 }

    项目代码示例:

     1 //c控制器里面这样写 CompanyInfoController 
     2 //公司信息
     3     public function actionIndex()
     4     {
     5         $result = CompanyService::CompanyInfo();
     6         $types = Yii::$app->params['companyType'];
     7         $model = CompanyInfo::find()->where(['id' =>Yii::$app->company->getId()])->one();
     8 
     9         if (Yii::$app->request->post() && CompanyService::UpdateConpanyInfo(Yii::$app->request->post())) {
    10             Yii::$app->session->setFlash('flag', 'success');
    11 
    12             return $this->redirect('/system/company-info/index');
    13         }
    14         return $this->render('index', [
    15             'staffNum' => $result['staffNum'],
    16             'model' => $model,
    17             'type' => $types,
    18             'businessList' => $result['businessList'],
    19             'businessParentId' => $result['businessParentId'],
    20             'sonBusInessList' => $result['sonBusInessList']
    21         ]);
    22     }
    23 
    24 //视图里面 index.php
    25 <script type="text/javascript">
    26         //消息提示start
    27         <?php $flag = Yii::$app->session->getFlash('flag');if($flag == 'success'): ?>
    28 
    29         layer.msg('公司信息更新成功');
    30 
    31         <?php endif; ?>
    32         //消息提示end
    33 
    34        
    35 </script>
