如何访问 Yii2 网格视图数据

Question

我已经在我的应用程序中实现了 yii2 网格视图，当我按下打印按钮时，我需要将网格视图的选定输出作为报告打印到 pdf 打印机。 我不知道如何访问网格视图的结果集并将其传递给我的控制器操作

我正在使用 kartik mpdf 扩展来生成 pdf

当我按下打印按钮时，我需要在网格视图中获取数据并将其传递到 mpdf 扩展名中。

这是我的视图文件的一部分

<?php
echo Html::a('<i class="fa far fa-hand-point-up"></i> Print', ['/pdfrpt/report'], [
'class'=>'btn btn-danger', 
'target'=>'_blank', 
'data-toggle'=>'tooltip', 
'title'=>'Will open the generated PDF file in a new window'
]);
?>
<?php Pjax::begin(); ?>
<?php // echo $this->render('_search', ['model' => $searchModel]); ?>
<?= GridView::widget([
'dataProvider' => $dataProvider,
'filterModel' => $searchModel,
'columns' => [
['class' => 'yiigridSerialColumn'],
'EmpNo',
['attribute'=> 'nameWithInitial',
'label' => 'Name',
'value' =>'empNo.nameWithInitial',],

这就是我所说的pdf(pdfrpt控制器中的报告操作(

public function actionReport() {
Yii::$app->response->format = yiiwebResponse::FORMAT_RAW;
$pdf = new Pdf([
'mode' => Pdf::MODE_CORE, 
'destination' => Pdf::DEST_BROWSER,
'content' => $this->renderPartial('test'),// here  I need to specify current grid view data
'options' => [
],
'methods' => [
'SetTitle' => 'Report title',
'SetSubject' => 'Generating PDF files via yii2-mpdf extension has never been easy',
'SetHeader' => ['report title||Generated On: ' . date("r")],
'SetFooter' => ['|Page {PAGENO}|'],
'SetAuthor' => '',
'SetCreator' => '',
'SetKeywords' => ' ',
]
]);
return $pdf->render();
}

你已经使用了分页错误，否则它会为第一页提供数据。

// create the data provider by configuring its pagination and sort properties
$provider = new XyzDataProvider([
'pagination' => [...],
'sort' => [...],
]);
// retrieves paginated and sorted data
$models = $provider->getModels();
// get the number of data items in the current page
$count = $provider->getCount();
// get the total number of data items across all pages
$totalCount = $provider->getTotalCount();
