如何将数据从模型传递到yii2中的视图

Question

这里，我试图设计一个工资单。我想从文本旁边的模型传递数据。像 -

<p class="text-center">Pay Slip for the month of </p> 

数据将从模型中提取，并会在“月份付款单”旁边传递。请帮忙。

我的控制器动作

public function actionPrintsalarystatement($id) { 

     //$model = Salary::find()->where(['s_id' => $id]); 
     $model = $this->findModel($id); 
     $searchModel = new SalarySearch(); 
     $dataProvider = $searchModel->search(Yii::$app->request->queryParams); 
     $data   = Salary::findOne($id); 
     $content = $this->renderPartial('_printSalarystatement', ['model' => $model,'dataProvider' => $dataProvider,'searchModel' => $searchModel,'data'=> $data]); 
     $pdf = new Pdf([ 
      'mode'=> Pdf::MODE_UTF8, 
      'format'=> Pdf::FORMAT_A4, 
      'destination'=> Pdf::DEST_BROWSER, 
      //'destination' => Pdf::DEST_DOWNLOAD, 
      'cssFile' => '@vendor/kartik-v/yii2-mpdf/assets/kv-mpdf-bootstrap.min.css', 
      // any css to be embedded if required 
      'cssInline' => '.kv-heading-1{font-size:18px}', 
      // set mPDF properties on the fly 
      'options' => ['title' => 'Print Payslip'], 
      // call mPDF methods on the fly 
      'methods' => [ 
       'SetHeader'=>['Private and Confidential'], 
       'SetFooter'=>['This Payslip is computer generated.'], 
      ], 
      'content'  => $content, 


     ]); 
     return $pdf->render(); 
     //return $this->render('_printSalarystatement', ['period' => 's_period']); 
    } 

_printSalarystatement.php

<?php

//$this->title = $model->s_id; 
$this->params['breadcrumbs'][] = ['label' => 'Salaries', 'url' => ['index']]; 
$this->params['breadcrumbs'][] = $this->title; 
?> 
<div class="salary-view"> 

    <h1><?= Html::encode($this->title) ?></h1> 
    <h1><strong><p class="text-center">PS Enterprise</p></strong></h1> 
    <p class="text-center">Pay Slip for the month of s_period </p> 


    <?= DetailView::widget([

     ], 
    ]) ?> 

</div> 

通过控制器动作，我得到了下面的屏幕

我想是要传递一个在周期详细视图将显示在“该月的付款单”行后面。我的问题是如何做到这一点

Answer 1

您需要将数据从controlleraction传递到您正在渲染的view。

e.g让你想从索引操作发送$name变量查看

行动会像

public function actionIndex() 
    { 
     return $this->render('index', ['name' => 'Tanmay']); 
    } 

现在你在render函数的第二个参数传递的数组是你的变量列表的希望。所有的键将作为索引视图

变量被处理为索引视图的代码将是

<h1>Welcome <?= $name; ?> 

即['name' => 'Tanmay']将被转换为$name具有值'Tanmay'

希望这有助于。 谢谢。

根据更新的问题更新时间：

$content = $this->renderPartial('_printSalarystatement', [ 
'model' => $model, 
'dataProvider' => $dataProvider, 
'searchModel' => $searchModel, 
'data'=> $data, 
's_period' => $s_period // new variable added 
] 
); 

在控制器

鉴于：

<p class="text-center">Pay Slip for the month of <?= $s_period; ?> </p>
