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
