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>
