Getting total page count from outside

[Nikita Savik]

Hello!

Here is the question: I need to get total page count from the generated pdf in the PHP script.

e.g.

$dompdf = new DOMPDF();

$dompdf->set_paper("a5","portrait");

$dompdf->load_html($html,'UTF-8');

$dompdf->render();

$pdf = $dompdf->output();

file_put_contents("test.pdf", $pdf);

echo "TotalPages ".$dompdf->get_page_count();

get_page_count is not working (taken from cpdf_adapter docs), Is there anything I can use instead of this?

Thanks in advance

You're close. The canvas object is defined as a property of the dompdf object. So the actual call is $dompdf->get_canvas()->get_page_count().

HI do you know the same in ZF2 ?? I am using dompdf with ZF2 but i dont knw how to get the tottal page number in pdf I tried a lot but didnt get any thing .. Current page number got via css but total is not . please help me ...

[BrianS]

Are you trying to retrieve the total page number externally from the PDF? Or do you want to write out the total number of pages inside the PDF (e.g. in a header/footer)?

Hii thank you very much for replying me .   Exactly I m trying to get the total page number inside the pdf  . (header/footer) . I get the current page number using the css property " counter(page) " but unable to retrieve the total number of pages using " counter(pages) "   . Is there any way to get this using zf2 dompdf module ??  .

Here is my code :

controller

 public function somePdfAction()
  {
    $labOrderid = $this->params('id');
    global $pid;   
    $pdf = new PdfModel();
    $pdf->setOption('filename', 'requistion' . $labOrderid); // Triggers PDF download, automatically appends ".pdf"
    $pdf->setOption('paperSize', 'a4'); // Defaults to "8x11"
    $pdf->setOption('paperOrientation', 'portrait'); // Defaults to "portrait"
 
    // To set view variables
    $pdf->setVariables(array(

     'someData' => $someData

    ));

    return $pdf;
  }

pdfView.phtml

  @page {
    margin: 170px 50px 0px 50px;
    counter-increment: page;
    counter-reset: page 1;
  }
  #header { position: fixed; left: 0px; top: -160px; right: 0px; height: 100px; text-align: center; background-color: white }
  #footer { position: fixed; left: 0px; bottom: 30px; right: 0px; height: 50px; background-color: white; }
  #content { padding: 0px; margin: 0px}
  #footer .page:after { content: "*****For Illustration Purposes Only****"}
  #header .page:after { content: "Page " counter(page);}

...... etc

Unfortunately dompdf does not yet support displaying the total page count using CSS. Until that functionality is available you would have to use inline script to display the total number of pages.

HI Brian

 I m trying to use the total number of page with zend frame work 2 . In ZF2 they use the dompdf model objects . So i didnt find how to use the inline php scripts with ZF2 . I saw that there are some function inside the dompdf moule libke  get_canvas()->get_page_num(), getcanvas->get_page_count() etc ... I serached a lot to get some to use it but i failed to impliment the same with ZF2 . If you have any idea to use this with ZF2 please share with me .. still i m stuck with this area .. Also I m a newbie in ZF2 .. Thanks a lot ....

Inline script is PHP code placed inside your HTML document, surrounded by <script type="text/php"></script> tags. Here's a question on StackOverflow that covers the basics:
http://stackoverflow.com/questions/7484318/header-in-pdf-page-using-dompdf-in-php

If that doesn't get you started post back and I'll provide more detail.

hi Brian the illustrated things are working with core php .. these did not work with ZendFramework2 .  But I need to work the same with dompdf in ZendFramework2 .

The following is my code :

At the top of the controller i have use the line like

use DOMPDFModule\View\Model\PdfModel;

 public function myPdfAction()

  {
    $labOrderid = $this->params('id');
    global $pid;   
    $pdf = new PdfModel();
    $pdf->setOption('filename', 'requistion' . $labOrderid); // Triggers PDF download, automatically appends ".pdf"
    $pdf->setOption('paperSize', 'a4'); // Defaults to "8x11"
    $pdf->setOption('paperOrientation', 'portrait'); // Defaults to "portrait"
   
  
    // To set view variables
    $pdf->setVariables(array(

      'var1' => $var1,
      'var2' => $var2,
      'var3' => $var3,
     

    ));
    return $pdf;
  }

In my  view there is corrospnding HTML codes ..

the pdfview.phtml file will render to pdf document . Here I need to display the total number of pages .

Thnk u Brian to keep continues replies .. thanks a lot ...

What do you mean that they do not work in ZF2? dompdf should render the document independent of any ZF2 functionality, it's basically a stand-along library wrapped in a ZF2 module. If inline script isn't working you might check your configuration file.
