Generating PDF Symfony2 IoTcpdfBundle - pdf

Question

I'm generating pdf file with IoTcpdfBundle using Symfony2, but there's a strange behaviour that I don't understand.
When I'm on the controller, I generate the pdf file like this:
$html = $this->renderView('MyBundle:Docs:solicituddevacaciones.pdf.twig', array());
return $this->get('io_tcpdf')->quick_pdf($html);
Those lines generate the pdf file. Everything's fine, I can right click on the file to save it and it's a .pdf file.
But when I receive some data using a form, and I put the lines inside the:
if ($request->getMethod() == 'POST') {
$year = $this->get('request')->request->get('year');
$date= $this->get('request')->request->get('date');
$html = $this->renderView('SoflaSoflaBundle:Documentales:solicituddevacaciones.pdf.twig', array());
return $this->get('io_tcpdf')->quick_pdf($html);
}
When I right click on the file to save it, it's not a .pdf file, the browser suggests that I should save the file as a .htm
Why is this happening? I need users to be able to save the files as .pdf files.
Need help with this please.

Answer 1

I had some similar problems and found out that the bundle might be outdated by now. I had to change some of the settings, most importantly adding another header to quick_pdf function of Tcpdf class in 'Helper' folder of the bundle:
$response->headers->set('Content-Disposition', 'attachment; filename="'.$file.'"');
Now it's working like a charm, calling it in the controller like:
$html = $this->renderView('Bundle:Item:print.pdf.twig', array(
'some' => $this->value,
));
return $this->get('io_tcpdf')->quick_pdf($html, "yourFileName.pdf");

Try to save the html (or better yet, left click instead of right click) and check the contents of that file. You probably have an error in ther somewhere, and that html file is the one generated by symfony to explain the error.
