我跟着關於knpsnappybundle在symfony3中使用pdf的教程，但問題是我需要傳遞一個值的數組到PDF頁面，所以我可以得到像原始的一個完整的頁面無法生成PDF Symfony 3
這裏是控制器：
public function pdfAction(){
$html = $this->renderView('@Recommendation/Recommendation/payment-successful.html.twig');
$filename = sprintf('test.pdf', date('Y-m-d'));
return new Response(
$this->get('knp_snappy.pdf')->getOutputFromHtml($html),
200,
[
'Content-Type' => 'application/pdf',
'Content-Disposition' => sprintf('inline; filename="%s"', $filename),
]
);
}
這裏與打印按鈕的代碼正常的頁面的圖像：
<a href="{{ path('payment_pdf') }}"><button>PRINT</button></a>
和路由：
payment_pdf:
path: /payment_pdf
defaults: { _controller: "RecommendationBundle:Recommendation:pdf"}
一個我原來的頁面的圖片：現在生成的PDF格式的圖片 https://i.stack.imgur.com/3MBEt.png
和： https://i.stack.imgur.com/rqs2x.png
看到該表是空的！
恕無法顯示圖像

單擊'PRINT'顯示什麼？ –
它顯示了pdf頁面 它將我帶到路線payment_pdf，它具有產生如上所述的pdf頁面的動作 –
您可以在做出更改之前和之後顯示您的樹枝文件'payment-successful.html.twig'。或者，如果你沒有舊的那個，就是現在的那個。 –
