我正在使用kartik-mpdf库生成我的gridviews的pdf，问题是我想将$ dataProvider和$ searchModel从index.php传递到将作为pdf文档（pdf.php）呈现的视图，因此，当我搜索索引并单击“ Generar pdf”按钮时，它将在AlumnoController上调用动作GenerarPdf，并将索引动作的相同$ searchModel和$ dataProvider加载到pdf.php gridview中并生成pdf文件。
这是代码。 AlumnoController.php-actionGenerarPdf
public function actionGenerarPdf($searchModel, $dataProvider)
{
Yii::$app->response->format = \yii\web\Response::FORMAT_RAW;
$formatter = \Yii::$app->formatter;
$pdf = new Pdf([
'mode' => Pdf::MODE_CORE, // leaner size using standard fonts
'destination' => Pdf::DEST_BROWSER,
//Se renderiza la vista "pdf" (que abrirá la nueva ventana)
'content' => $this->renderPartial('pdf', [
'searchModel' => $searchModel,
'dataProvider' => $dataProvider
]),
'options' => [
// any mpdf options you wish to set
],
'methods' => [
'SetTitle' => 'SIE: Sistema de Informacion Estudiantil',
'SetSubject' => 'Generating PDF files via yii2-mpdf extension has never been easy',
'SetHeader' => ['SIE: Sistema de Información Estudiantil||Generado el: ' . $formatter->asDate(date("r"))],
'SetFooter' => ['|Página {PAGENO}|'],
'SetAuthor' => 'SIE: Sistema de información Estudiantil',
'SetCreator' => 'Juan Carlos Reyes Suazo',
// 'SetKeywords' => 'Sie, Yii2, Export, PDF, MPDF, Output, yii2-mpdf',
]
]);
return $pdf->render();
}
index.php

<?php
if (User::isSuperAdmin(Yii::$app->user->identity->id)){
echo Html::a('Crear Alumno', ['create'], ['class' => 'btn btn-success']);
echo Html::a('Ver PDF', [

'searchModel' => $searchModel,

任何帮助将不胜感激。

我通过使用会话解决了这个问题，并在actionGenerarPdf中生成了$ searchModel和$ dataProvider，而不是通过按钮发送了它们。
我将在yii论坛中引用@softark
“您不能将$ searchModel和$ dataProvider作为查询参数传递给操作方法，因为它们不是可以转换为简单字符串的简单变量。
因此，您必须在actionGenerarPdf方法中创建搜索模型和数据提供程序。
为了获取索引操作中使用的搜索参数，可以将查询参数存储在会话中，然后在actionGenerarPdf中检索它们。”
这是代码
public function actionIndex()
{
$searchModel = new AlumnoSearch();
$dataProvider = $searchModel->search(Yii::$app->request->queryParams);
$session = Yii::$app->session;
$session->open();
$session['query_params'] = json_encode(Yii::$app->request->queryParams);
$session->close();
return $this->render('index', [
'searchModel' => $searchModel,
'dataProvider' => $dataProvider,
]);
}
public function actionGenerarPdf()
{
$session = Yii::$app->session;
$session->open();
$queryParams = isset($session['query_params']) ? json_decode($session['query_params'], true) : [];
$session->close();
$searchModel = new AlumnoSearch();
$dataProvider = $searchModel->search($queryParams);
Yii::$app->response->format = \yii\web\Response::FORMAT_RAW;
$formatter = \Yii::$app->formatter;
$pdf = new Pdf([
'mode' => Pdf::MODE_CORE, // leaner size using standard fonts
'defaultFontSize' => 18,
'orientation' => Pdf::ORIENT_PORTRAIT,
'destination' => Pdf::DEST_BROWSER,
//Se renderiza la vista "pdf" (que abrirá la nueva ventana)
'content' => $this->renderPartial('pdf', ['searchModel' => $searchModel, 'dataProvider' => $dataProvider]),
'options' => [
// any mpdf options you wish to set
],
'methods' => [
'SetTitle' => 'SIE: Sistema de Informacion Estudiantil',
'SetSubject' => 'Generating PDF files via yii2-mpdf extension has never been easy',
'SetHeader' => ['SIE: Sistema de Información Estudiantil||Generado el: ' . $formatter->asDate(date("r"))],
'SetFooter' => ['|Página {PAGENO}|'],
'SetAuthor' => 'SIE: Sistema de información Estudiantil',
'SetCreator' => 'Juan Carlos Reyes Suazo',
// 'SetKeywords' => 'Sie, Yii2, Export, PDF, MPDF, Output, yii2-mpdf',
]
]);
return $pdf->render();
}
我希望这对希望达到相同目标的人有所帮助
