FPDI : Call to undefined method FPDI::_getrawstream() on Drupal

Question

I try to use the FPDI lib with Drupal to concatenate pdf together. I created a class to add a new pdf to fpdi :

class PdfGenerator
{
public function importPDF(&$fpdi, $file)
  {
      $pageCount = $fpdi->setSourceFile($file);
      for ($p = 1; $p <= $pageCount; $p++) {
          $tplidx = $fpdi->importPage($p);
          $size = $fpdi->getTemplatesize($tplidx);

          if ($size['w'] > $size['h']) {
              $format = 'L';
          } else {
              $format = 'P';
          }

          $fpdi->addPage($format, array($size['w'], $size['h']));
          $fpdi->useTemplate($tplidx);
      }
  }
}

and I call the importPDF method like this:

$pdf = new FPDI();
$pdf_path = 'path/to/pdf.pdf';
$pdfGenerator->importPDF($pdf,$pdf_path);
$pdf->Output('test.pdf','I');

But unfortunately I have this error :

Fatal error: Call to undefined method FPDI::_getrawstream() in [..]sites/all/libraries/fpdi/fpdi.php on line 473

Do you know the reason for this error ?

thank you in advance :)

Answer 1

I found the solution: I actually use HTML2PDF before FPDI to generate a PDF.

• HTML2PDF makes an include of an outdated version of TCPDF (5.0.002)

So when I use FPDI, the type of the fpdi object instantiate is TCPDF and not FPDF. And FPDI called a function of TCPDF which appears on the v6 of TCPDF.

The solution : I Downgraded FPDI to the version 1.3.3 to match to html2pdf (v5.0.002) And I took fpdf_tpl version 1.2.2 to match to the fpdi lib v1.3.3

And this works !

Make sure that you update FPDI and FPDF to their latest versions.
