[dokuwiki] pdf export


Hi!

I created a simple (well, more or less) solution to get the wiki content into a pdf file. Now I'm asking for comments, suggestions and a second opinion.

Here's what worked for me:
1) I donwloaded the "html2ps and html2pdf" PHP library from http://www.tufat.com/script19.htm. It worked amazingly vell for almost every html page I tested it with (has image support, loads of options and so on)

2) Based on the samples in html2pdf I created the attached url2pdf.php script into 'samples' directory of html2pdf and configured the whole thing work in my webserver.

3) Now we reach the connection to dokuwiki. In the main.php I added manually a PDF button (I really could not find a way to create the button automagically with dokuwiki scripts as these allowed only posting to dokuwiki itself). So here's the listing of the PDF button code which I placed right after the History button:

<form class="button" method="get" action="http://localhost/html2pdf/samples/url2pdf.php";><div class="no"><input type="hidden" name="url" value="<?= "http://".$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI'] ?>" /><input type="submit" value="Save as PDF" class="button" title="ALT+F" accesskey="f" /></div></form>

4) The result - I have button which prompts me of saving the page as PDF. Very useful. And quite clean.

So it's kind of a hack, and I am writing because if there's a better way to create the button and to know the _real_ _absolute_ url for the current wiki page then please let me know. If you find it any other way useful or someone can import this to be a dokuwiki feature then this would be even nicer.


best regards,
Heikko
