Export DokuWiki Page to PDFs

Several users proposed a way how to convert your HTML wiki pages to PDFs. Therefore you'll find 3 different solutions to the same problem on this page and another one on pdfdownload. The page exporting_pdf may be of interest, too.

You can also see this page htmldoc

In order to export your pages to PDF you'll need to add a button to your wiki. Regardless which PDF converter you use, you need to implement the following changes:

• Add an Export to PDF button by editing lib/tpl/main.php like so:

      <div class="bar" id="bar_top">
        <div class="bar-left" id="bar_topleft">
          <?php tpl_button('edit')?>
          <?php tpl_button('history')?>
          <?php print html_btn('exportpdf',$ID,'',array('do' => 'export_pdf')) ?>  <!-- inserted line -->
        </div> 

  (If you want the button to appear in the bottom bar use id=“bar_bottom”)

• Add a new string to inc/lang/en/lang.php (or whatever language you use):

  $lang['btn_exportpdf'] = 'Export to PDF'; 

• In order to display a small pdf icon instead of the above “Export to PDF”, do the following in inc/html.php

Search for this line

$ret .= '<input type="submit" value="'.htmlspecialchars($label).'" class="button" ';

and replace with this.

//This allows the insertion of an icon in the menu bar
if ($name=="exportpdf"){
$ret .= '<input type="image" src="../lib/images/fileicons/pdf.png" value="'.htmlspecialchars($label).'" ';
}else{
  $ret .= '<input type="submit" value="'.htmlspecialchars($label).'" class="button" ';
}

Q: Where I will find required file /lib/plugins/pdf/renderer.php (and rest of files from /lib/plugins/pdf/) ?

A: ???

Using the html2ps PHP script requires only little changes and additions to the DokuWiki source code.

• Install html2ps. (To run the php script you'll need ghostscript or libpdf - install them first!)
• Add the Export to PDF button as described above.
• In the function act_export, in inc/actions.php, add this:

    if ($act == 'export_pdf')
    {
   header("Location: " . DOKU_BASE.'html2ps/html2ps.php?URL='.urlencode(wl($ID, '', true)).'&pixels=1024&media=A4&ps2pdf=2&output=0&cssmedia=screen&renderimages=1&scalepoints=1&leftmargin=10&rightmargin=10&topmargin=10&bottommargin=10');
      exit;
    } 

If you want to remove the wiki structures and send the raw html page to the pdf exporter, edit the above so that

• urlencode(wl($ID, '', true))

  ⇒

  urlencode(wl($ID, '', true).'&do=export_html')

You may also wish to vary other options for the html2ps command, these can be found in the documentation on the html2ps site. I add renderlinks=1 and method=fastps (for building using ghostscript) to mine.

If your Wiki uses https, then get the patch for html2ps.

This appears to only work with pages that allow anonymous read access.

*Is-someone knows where I can found the html2ps.php file ?. It's not provided with the package. Thanks.
