Remove header from pdf file

[artworkad]

Hey folks,

when I generate a pdf it always has this

HTTP/1.0 200 OK Cache-Control: no-cache Date: Sun, 20 Jan 2013 11:17:25 GMT

at the top. How can I avoid that?

If you are using render method for the html generation, you should change to renderView.

put here how you response a pdf file

   $html = $this->render('MyMainBundle:CRM:pdf.html.twig', array(
        'request' => $cr_request
   ));

    return new Response(
                    $this->get('knp_snappy.pdf')->getOutputFromHtml($html),
                    200,
                    array(
                        'Content-Type' => 'application/pdf',
                        'Content-Disposition' => 'attachment; filename="Customer-Request.pdf"'
                    )
    );

You have those headers because you call it via Symfony2 Response. Is this a real problem that you have this header? Because this is standard header for HTTP responses (just sometimes "cache" is omitted). Or you want different? Then you can manipulate headers of response in Symfony2... Here is with simple echo.

$html = $this->render('MyMainBundle:CRM:pdf.html.twig', array(
    'request' => $cr_request
));

header('Content-Type: application/pdf');
header('Content-Disposition: attachment; filename="file.pdf"');
echo $this->get('knp_snappy.pdf')->getOutputFromHtml($html);

Closing this as this is not an issue.

getContent() will keep you from grabbing the headers.

$html = $this->render('MyMainBundle:CRM:pdf.html.twig', array(
        'request' => $cr_request
   ))->getContent();


    return new Response(
                    $this->get('knp_snappy.pdf')->getOutputFromHtml($html),
                    200,
                    array(
                        'Content-Type' => 'application/pdf',
                        'Content-Disposition' => 'attachment; filename="Customer-Request.pdf"'
                    )
    );

Or just use the renderView method instead of the render method as said by @galan83

$html = $this->renderView('pdf.html.twig', array(/* vars to pass to the twig template */) );

return new Response(
	$this->get('knp_snappy.pdf')->getOutputFromHtml($html),
	200,
	array(
		'Content-Type'          => 'application/pdf',
		'Content-Disposition'   => 'inline; filename="file.pdf"'
		//inline = display in browser, attachment = download
	)
);

@stloyd you misunderstood the issue, the op meant that the headers were actually displayed as text in the pdf

The last part of the previous solutions did not work for me, but this way it work for me.

        return new PdfResponse(
            $this->get('knp_snappy.pdf')->getOutputFromHtml(
                $this->renderView('GeneralBundle:pdf:pdf.html.twig', array( /*vars*/ ))
            ),
            $filename . '.pdf'
        );
