如何在Yii2中使用kartik mpdf将HTML页面导出为PDF？

Question

我需要将我的html文件导出为Pdf格式并将其保存到pdf文件夹中。 到目前为止，我已经做到了这一点。

  

这是我保存为messagesend.php的html页面，需要导出。

 use kartik\mpdf\Pdf;
public function actionReport() {
// get your HTML raw content without any layouts or scripts
$content = $this->renderPartial('messagesend');

// setup kartik\mpdf\Pdf component
$pdf = new Pdf([
    // set to use core fonts only
    'mode' => Pdf::MODE_CORE, 
    // A4 paper format
    'format' => Pdf::FORMAT_A4, 
    // portrait orientation
    'orientation' => Pdf::ORIENT_PORTRAIT, 
    // stream to browser inline
    'destination' => Pdf::DEST_BROWSER, 
    // your html content input
    'content' => $content,  
    // format content from your own css file if needed or use the
    // enhanced bootstrap css built by Krajee for mPDF formatting 
    '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' => 'Krajee Report Title'],
     // call mPDF methods on the fly
    'methods' => [ 
        'SetHeader'=>['Krajee Report Header'], 
        'SetFooter'=>['{PAGENO}'],
    ]
]);

// return the pdf output as per the destination setting
return $pdf->render(); 

现在下面是我用来生成pdf的控制器。

List<Item> items = new List<Item>();
if(!string.IsNullOrEmpty(_txtboxId_)
{
    items = dbContext.Items.Where(m => m.Id.Contains(_txtboxId_).ToList(); 
}
else
    items = dbContext.Items.ToList();

if(!string.IsNullOrEmpty(_txtboxBuyer_)
{
    items = dbContext.Items.Where(m => m.Id.Contains(_txtboxBuyer_).ToList();

}
else
    items = dbContext.Items.ToList();

if(!string.IsNullOrEmpty(_txtboxPrice_)
{
    items = dbContext.Items.Where(m => m.Id.Contains(_txtboxPrice_).ToList();

}
else
    items = dbContext.Items.ToList();

}

现在显示以下错误。下图中出错。

我现在如何生成Pdf？我也是新手，所以你们可以向我解释一下吗？

Answer 1

您必须请求与您的操作相对应的网址：http://example.com/yourcontroller/report

如果要生成PDF并将其存储在服务器中，则必须将destination更改为Pdf::DEST_FILE，指定路径/​​文件名。查看docs。

Answer 2

在这里，要使用mPDF创建演示文稿的PDF文件。

/*
     * GENERATE PDF OF SAMPLE
     */

    public function actionSamplePdf($id) {

        $data = $this->findModel($id);

        // get your HTML raw content without any layouts or scripts
        $content = $this->renderPartial('_samplePdf', ['model' => $data]);

        $destination = Pdf::DEST_BROWSER;
        //$destination = Pdf::DEST_DOWNLOAD;

        $filename = $data->file_name . ".pdf";

        $pdf = new Pdf([
            // set to use core fonts only
            'mode' => Pdf::MODE_UTF8,
            // A4 paper format
            'format' => Pdf::FORMAT_A4,
            // portrait orientation
            'orientation' => Pdf::ORIENT_PORTRAIT,
            // stream to browser inline
            'destination' => $destination,
            'filename' => $filename,
            // your html content input
            'content' => $content,
            // format content from your own css file if needed or use the
            // enhanced bootstrap css built by Krajee for mPDF formatting 
            'cssFile' => '@vendor/kartik-v/yii2-mpdf/assets/kv-mpdf-bootstrap.min.css',
            // any css to be embedded if required
            'cssInline' => 'p, td,div { font-family: freeserif; }; body, p { font-family: irannastaliq; font-size: 15pt; }; .kv-heading-1{font-size:18px}table{width: 100%;line-height: inherit;text-align: left; border-collapse: collapse;}table, td, th {border: 1px solid black;}',
            'marginFooter' => 5,
            // call mPDF methods on the fly
            'methods' => [
                'SetTitle' => ['SAMPLE PDF'],
                //'SetHeader' => ['SAMPLE'],
                'SetFooter' => ['Page {PAGENO}'],
            ]
        ]);

        // return the pdf output as per the destination setting
        return $pdf->render();
    }
