Question

I’m trying to user HTML2FPDF (http://html2fpdf.sourceforge.net/) to create a PDF of a page, but I can’t seem to get it to work properly.

My page consists of jQuery to show a graph. I want the graph and other text on the page to be exported as a PDF.

http://portal.flyingstartlifestyle.360southclients.com/leanne/leanne.php <- the graph with the html2fpdf code at the bottom of the page.

HTML2FPDF code:

function createPDF() {

 define('ABSPATH', dirname(__FILE__).'/');

 require(ABSPATH.'classes/pdf/html2fpdf.php');

 $pdf = new HTML2FPDF();
 $pdf->AddPage();

 $html = ob_get_contents();
 //$html = htmlspecialchars($html);

 if ($html) {

  $fileName = "testing.pdf";

  $pdf->WriteHTML($html);
  $pdf->Output("pdfs/".$fileName);

  echo "<p>PDF file is generated successfully! <a href=\"pdfs/$fileName\" target=\"_blank\">Click here</a> to open it.</p>";

 } else {

  echo "<p>There has been an error in creating your PDF.</p>";

 };


};

If I unhide the line “$html = htmlspecialchars($html);” it prints the pdf the text of the page, otherwise it creates an empty PDF. Any ideas how I can transfer my graph to a PDF?

Cheers

jQuery is interpreted by the browser and not by the server. When you send the HTML to be rendered into PDF, it will not run the Javascript. You’ll need to find a way to actually generate the image some other way.
