Symfony 2 + dompdf

Question

我目前無法使dompdf工作。如果我包括dompdf流它不會出現任何東西。有人可以請建議/告訴我我如何獲得pdf保存。

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' 

    )); 


} 

}

我渲染我喜歡這種形式的數據。

<p><strong>Personal Details</strong></p> 
<p>Firstname: {{ data.firstname }}</p> 
<p>Middle Name: {{ data.middlename }}</p> 
<p>Surname: {{ data.lastname }}</p> 
<p>Nationality: {{ data.nationality }}</p> 
<p>DOB: {{ data.dateOfBirth | date }}</p> 
<p>National Insurance Number: {{ data.nationalInsuranceNumber }}</p> 
<p>Preferred retirement age: {{ data.preferredRetirementAge }}</p> 

string '<h1>DIRECT</h1> 
<p><strong>Personal Details</strong></p> 
<p>Firstname: sham</p> 
<p>Middle Name: </p> 
<p>Surname: test</p> 
<p>Nationality: British</p> 
<p>DOB: January 10, 1985 00:00</p> 
<p>National Insurance Number: QQ 12 34 56 A</p> 
<p>Preferred retirement age: 65</p>
