I noticed a problem with thew ExportPdf extension, If I try to generate the page I'm viewing, ie: http://WIKI_SITE/w/index.php?title=Special:PdfPrint&page=My_Document_Page
It fails and generates a dummy PDF with nothing really in it. If I go to the Special page manually then in the 'Enter the title of the page you want to export to PDF' put the *actual* document title 'My Document Page' it works, is this a known issue? If so, is there any workarounds?
Thanks
This seems to be related to the underscore‒space equivalence/conversion in Mediawiki. A workaround that does the job in my case is to add, between the following two lines in extensions/PdfExport/PdfExport_body.php,
if ($dopdf) {
$wgOut->setPrintable();
(approx. line 111) the new line
array_walk($pages, function(&$val, $key) {$val = strtr($val, '_', ' ');});
which converts underscores to spaces.
This requires PHP ≥ 5.3 because of the anonymous function (a. k. a. closure) created by the function keyword, but it could easily be rewritten using create_function().
I have a similar problem in our Wiki. (It's german btw) The spaces are not a big deal in our Wiki, but when I'm trying to export a PDF with umlauts (äöü) in the title, I get the same empty document as the thread opener. Do you have an idea how to fix this?
Today I found a solution for this. If you're using the MwLibPdfConverter.php you can add
setlocale(LC_CTYPE, "en_US.UTF-8");
at line 5. After this the PDF were created correctly.
I had the same issue with MwLibPdfConverter.php but the setlocale did not fix my issue.
Instead I modified it on line 45 to include this:
$page = strtr($page, '_', ' ');
