如何在laravel中使用mpdf为每个页面添加水印

Question

I'm using niklasravnsborg/laravel-pdf package in laravel to generate a pdf. In this code i added watermark but that watermark is coming only on the last page though i wanted that to be in every page.

$pdf = PDFm::loadHtml($result->document);
$pdf->mpdf->SetWatermarkText('DRAFT');
$pdf->mpdf->showWatermarkText = true;
return $pdf->download('hdtuto.pdf');

Answer 1

From the documentation, it should work. Could you however, give the following a try?

$config = ['instanceConfigurator' => function($mpdf) {
    $mpdf->SetWatermarkText('DRAFT');
    $mpdf->showWatermarkText = true;
}]

PDF::loadHtml($result->document, $config)->download('hdtuto.pdf');

In this case, we are initialising the PDF instance with the right configuration instance, instead of doing it after loading the HTML.
