Symfony 2 + dompdf

Question

我目前无法让dompdf工作。如果我包含dompdf流，它似乎没有任何东西。有人可以建议/告诉我如何保存pdf。

public function indexAction()
{
    $formData = new LimitedDirectApplication();
    $flow = $this->get('shapehq.form.flow.limitedDirectApplication');
    $flow->bind($formData);
    $form = $flow->createForm();
    if ($flow->isValid($form)) {
        $flow->saveCurrentStepData($form);
        if ($flow->nextStep()) {
            // form for the next step
            $form = $flow->createForm();
        } else {
            // flow finished
            $em = $this->getDoctrine()->getManager();
            $this->pdfAction($formData);
            //var_dump($formData);die();

            $em->persist($formData);
            $em->flush();
            $flow->reset(); // remove step data from the session
            $this->sendSuccessEmail($formData);
            return $this->redirect($this->generateUrl('shape_hq_greyfriars_sipp_homepage')); // redirect when done
        }
    }
    return $this->render('ShapeHQGreyfriarsSippBundle:Application:directLimitedApplication.html.twig', array(
        'form' => $form->createView(),
        'flow' => $flow,
    ));
}

public function pdfAction($formData)
{

    require_once('/var/www/src/backend/app/config/dompdf_config.inc.php');

    $html = $this->renderView(
        'ShapeHQGreyfriarsSippBundle:Application:DirectApplicationPDF.html.twig',
        array('data' => $formData)
    );

    $dompdf = new \DOMPDF();
    $dompdf->load_html($html);
    $dompdf->render();


    //check whether there is a output folder
    return new Response($dompdf->output(), 200, array(
        'Content-Type' => 'application /pdf'

    ));


}

}

我正在渲染我的表单数据。

Answer 1

在render()

之后尝试此操作

$dompdf->stream( $pdfname );
