There seems to be a licensing problem with htmldoc for windows installations ?

I did not manage to open pdf file, so I had to add a header line to download the pdf

Furthermore, htmldoc does not support unicode, I began a translation utf8 to latin1 for displaying french characters correctly , this may need enhancements.

Patch for version 2.3
I've extended version 2.3 (2010-01-28) with some additional features:


 * special page
 * allow fontface to be picked
 * allow fontsize to be set
 * setting pdf-permissions to either "all" or "none"
 * allow margins (top/sides/bottom) to be defined


 * other
 * defined "$wgPdfExportBackground" which can be used to set an image which is then applied as background to each and every site of the resulting pdf

'What's the process for a review of the patch? How should I provide that new version? Post it here?'

SpecialPDF and MimeTeX
This is a really cool and useful extension. HOwever, it is ignoring an extension we added to support MimeTeX so that the output does not include any math created through that extension.

Our MimeTeX extension replaces Any LaTeX formula

Is there another way we should be generating this so that SpecialPDF can capture the image? DavidJameson 20:32, 4 August 2006 (UTC)

Updated for unicode, multiple articles, and images
Searched around for a way to do multiple articles to PDF, had to combine what was listed here and what was contained in wiki2pdf. Works the same way as SpecialPDF.php, put it in your extensions folder. HTML files are created (for processing) in your /webroot/wikiroot/pdfs folder (so create it if you don't have it) or another folder of your choice. It still uses HTMLDOC with some switches to format headers and footers, and there are string substitutions for the images exported out of the Wiki...

This doesn't work for me - I've added the php file to the extensions folder and altered Localsettings.php to include it. When I navigate to my site I just get a blank page rather than logon. I'm obviously missing something blindingly obvious.....

Hello Editing the Page

Bad argument to HTMLDOC
myPDF is not working for me. It's generating a bogus arg to HTMLDOC and so instead of getting a PDF file, I get a file with the error message:

HTMLDOC Version 1.8.27 Copyright 1997-2006 Easy Software Products, All Rights Reserved. This software is based in part on the work of the Independent JPEG Group.

ERROR: Bad option argument "--charse "!

Note that there should be a 't' at the end of the argument but instead there is an embedded CR control character

DavidJameson 14:22, 5 September 2006 (UTC)

SCW, 05sept06, 10:09CT
A line break got into the cut and paste on that line for htmldoc passthru. take out the linebreak to join the lines together to make the argument to htmldoc '--charset' and all should be okay.

I'll be posting a newer version that has th option for creating PDF books with a title page, TOC and nice nesting of articles...

Simon.

No HTML files found
I must be missing something else....after fixing the linebreak problem, I opened a wikipage and then clicked on Export PDF book.

This time I got a file with the error:

HTMLDOC Version 1.8.27 Copyright 1997-2006 Easy Software Products, All Rights Reserved. This software is based in part on the work of the Independent JPEG Group.

ERROR: No HTML files!

Usage: htmldoc [options] filename1.html [ ... filenameN.html ] htmldoc filename.book

What's this notion about a "collection" of articles? Is there something I'm supposed to do to "collect" some articles together before I can print them? How would I do that, and why would I need to? The "Export PDF Book" link shows up in Toolbox when I'm viewing a particular page - So how can generate THAT page as PDF but including all images?

DavidJameson 15:36, 5 September 2006 (UTC)

okay, the following script is based of the original, temporary PDF files are saved to /tmp, like they were in the original. This script will not deal with putting multiple articles into one PDF file (see above for that). It will handle image files.

Almost there (grin)
Well, this version almost works perfectly - it gave me a nice PDF file with explicit images referenced in the wiki page.

However, it crashes when trying to handle one of the image tags produced by our MimeTex math generator.

E.g.

<img src="/cgi-bin/mimetex.cgi?\green f(\xi)=\int_{-\infty}^\xi e^{-\tau^2}d\tau { {x \atop y } }" align="absmiddle" border="0" alt="TeX Formula">

seems to cause a crash.

I wonder if the code that tweaks the IMG tag itself is getting confused with the more sophisticated stuff in this particular image reference.

DavidJameson 12:10, 6 September 2006 (UTC)

PHP error
Just for grins, I ran the process through a PHP debugger. The debugger barfed with the error below. Error: E_ERROR Call to a member function getNamespace on a non-object at /var/www/html/wikiroot/riskit/includes/Article.php line 155

The line it's complaining about is			if ( $this->mTitle->getNamespace == NS_MEDIAWIKI ) { which is found in the function getContent in Article.php

(P.S.....someone needs to install the GESHI syntax highlighting extension on wikimedia.org)

DavidJameson 12:18, 6 September 2006 (UTC)

PHP error
OK - I've figured out both problems (to an acceptable extent)

1) The PHP bug is due to the fact that sometimes (and I don't know why it's only sometimes), the URL associated with the Print As PDF command in the toolbox has %0D%0A tacked on at the end. No idea where this is coming from but it can be removed by modifying the echo statement on line 103, adding a str_replace function to remove the extra characters. php echo htmlspecialchars( str_replace('%0D%0A', '', $monobook->data['nav_urls']['pdfprint']['href'] ))

2) The reason the math images weren't being processed was because the URL in the SRC attribute of the IMG tag did not include the server. I modified my mimetex extension to include the server but this problem will arise again for anyone else who references an image without using a server in the URL. The full solution will require the text to be searched for all image urls, examine them to see if there's a server part and if not, insert the $wgServer into the string. Probably can be done quickly with a regex. DavidJameson 20:31, 6 September 2006 (UTC)


 * What's wrong with just doing this: "$bhtml = str_replace ('/images/',$wgServer . '/images/', $bhtml);" instead of the $bhtml = str_replace ('/w/',$wgServer . '/w/', $bhtml); that you have there? Made the math images all work for me. --dgrant 18:30, 25 October 2006 (UTC)

Possible Image Fix
This solution almost works for me - but it led me to the right answer: Add these two lines where the other globals are defined:

and then change

to

For me this fixed the problem with images but internal links to wiki pages still didn't work. These links are relative just like the images and need to be absoluted. --justinm

Images With Windows
I managed to get this working by inserting the following:

I don't really know if this is the best way to do it, but it fixed my problem with the html being generated as:

Images When Wiki Is Root of Domain
The string replacement

doesn't do anything if  is the empty string. This is the case if the wiki is the root of the domain.

I've fixed this by replacing the above line with

so both the  and the   attributes are fixed up.

It seems to me that the root of these problems is that there's no way to pass a default server prefix to.
 * You could try Extension:PdfBook, it can also export single pages now and images work fine on it. --Nad 21:13, 2 November 2008 (UTC)
 * Thanks Nad. this worked. Using a redirect and virtual host in Apache, server.oursite.org/wiki becomes wiki.oursite.org/. With your edit, images appear again on the PDFs. --Erikvw 11:11, 17 December 2008 (UTC)

More generic fix
Thanks to all for pointing me in the right path to fix this on my wiki. After looking at a few wiki installations, it appears some problems can be seen when wgScript to an empty string, while others choose not to use the default path to articles. Either $wgScript or wgScriptPath may together serve as the generic approach to finding the absolute path to an article however. The following should help images display, and fix relative links, while maintaining all absolute links. Please comment/improve as needed:

Replace the following two lines in PdfExport_body.php (same as others have pointed out):

with the following: --Biyer 16:05, 25 January 2010 (UTC)

what files should be changed ?
Very nice this solutions, but which files should be editted?

Possible Fix
on UNIX: check the DNS-Resolution on the webserver which host the wiki (nslookup or dig). Is there no resolution for your wiki-domain, htmldoc can not read the images from servers (and gives also no errors out). But the generated PDF contains no images.

Still Still no Images
hello, after some problems with htmldoc this extension works on my wiki, but in pdfs there are no images. i tried all this solutions, but no one works on my (windows) system. Are there other solutions/fixes ?

Thanks. Johannes741 14:35, 25 May 2010 (UTC)

No images if you use security
While we're piling hack upon hack, here is mine. Our wiki is secured using mod_auth_ntlm (its a WAMP) but this will work for anyone who has a .htaccess as well.

Empty Files
Help, i only get empty files.

 * I had this problem on Windows XP. Took me hours to figure out.  I moved the C:\Program Files\HTMLDoc to C:\HTMLDoc, added HTMLDoc as a virtual directory, then in the PDFExport.php I use the line:


 * The problem occurred because of the space between in "Program Files", and if I remember correctly it WOULD NOT WORK if you do not append the .exe to htmldoc
 * You could have also used c:\progra~1 and left HTMLDOC where it was. Kids today...

Clean code
Hi there, would be nice if you could post the clean code with all above corrections included. I tried them all with mediawiki 1.8.2 but I can't get it to work. Cheers Florian

Test and working on 1.9
this was tried on Linux/Apache/PHP5 with 1.9 in a software configuration very simillar to Wikipedia and works fine. tom

Working code for Windows with MediaWiki v1.9
The PDF export worked for me on Windows after I fixed the path AND more importantly on line 80, I had to change '$mytemp' to $mytemp - i.e. remove the single quotes aroung $mytemp.

Page rendering
Hello, I'd wish some improvement of this useful extension. While it works technically it's a fact that the pages look better when printed to a PDF printer over your web browser. To have an improvement compared to web broweser PDFs it should look more LaTeX-style. --Ikiwaner 00:00, 16 January 2007 (UTC)

A problem with htmldoc encoding
htmldoc is very sensitive about the encoding.

In file SpecialPdf.php, line 89 passthru("/usr/bin/htmldoc -t pdf14 --charset 8859-1 --color --quiet --jpeg --webpage..., for the new version of htmldoc --charset should be iso-8859-1 Ivan

What is the purpose of HTMLDOC, if it's Windows app?
Hi all

I don't quite understand, if HTMLDOC is a windows application, how will this help me if my web server is a Linux server? There is also a Linux Version!

A problem with PHP passthru
Thanks for the extension! I'm using MediaWiki 1.8.2 on Windows 2003 and it's work. I had a problem with the passthru fonction that i solved by copying cmd.exe in the php installation folder.

Where do I download extension
Can't seem to find SpecialPage.php, where do I download the file?


 * Just cut and paste the code above into a text file with that name and extension. Jschroe

Scaling Images to fit paper width
I found an argument to htmldoc, that allows you to specify the 'width' of the page in pixels, which is sort of the opposite of scaling, but rather, setting the viewable resolution for the images. So, I have an image that is 900 pixels wide, I'd want to set my browser width to something greater than 900 to see the whole image at once. passthru("htmldoc -t pdf14 --charset iso-8859-1 --color --quiet --jpeg --webpage '$mytemp'"); would become: passthru("htmldoc -t pdf14 --browserwidth 950 --charset iso-8859-1 --color --quiet --jpeg --webpage '$mytemp'"); --DavidSeymore 18:48, 14 May 2007 (UTC)


 * doesn't work for me - I ended up having to use getimagesize and adding a max-limited width parameter which isn't ideal.

Title of Wiki-Article in PDF
Hi,

i was wondering if it it possible to display the title of the Wiki article in the generated PDF?!THX

Change $html = "  ". $page. "  " . $bhtml. " ";   to something like $html = "    <H1>". $title. "</H1>". $bhtml. " ";  Suspect

Name of the generated file
The extension works fine except for the fact that is outputs a file called index.php, renaming this to something.pdf works as it is in fact an pdf file. But I m wondering how I could fix it so it outputs <article_name.pdf>. Any suggestions?

Solution
In file PdfExport_body.php line 95 : - header(sprintf('Content-Disposition: attachment; filename="%s"', $wgRequest->getText('filename'))); + header(sprintf('Content-Disposition: attachment; filename="%s.pdf"', $pages[0])); You get <article_name.pdf> instead of <index.php>.

Generated PDF is 1kb and corrupted
I am testing MW 1.10.1 on a LAMP system (upgraded from 1.6.7). Then tried the instructions on the main article page. After clicking on the Print to PDF link though I get a 1kb PDF. Any ideas as to what could be wrong? How do i go about fixing this? SellFone 07:23, 3 August 2007 (UTC)

Solution
I downloaded the HTMLDOC Binary and i didnt realize that you had to pay for it. When I ran it, it asked for a license and so I went ahead and installed gcc & gcc-c++ so i could compile from source and now its working.

Patch to Export Multiple Pages to PDF
This patch creates a Special Page form similar to Special:Export for specifying multiple pages to export to PDF. This patch was created against the 1.1 (19-July-2007) version of PdfExport and tested in MediaWiki 1.11.

Fedora C 4 fix
I have installed the pdf export extension and added the code in localsettings.php and my wiki just shows a blank screen when I install this extension. I have installed htmldoc and it works from command prompt.

Has anyone a solution,, to get this run under windows ?
Please post here. Export works already fine, but the pdf file is empty.

 * The code as posted above under Working Code for Windows with MediaWiki v1.9 works.. you just need to make sure the temp file path exists and is writable, and that IIS anonymous user has access to cmd and anonymous access is possible for images.. Suspect

Fatal Error
Call to undefined method: specialpdf->__construct in /usr/home/admin/domains/< >/public_html/mediawiki-1.6.10/extensions/PdfExport/PdfExport.php on line 51

This occurs when opening any page in MediaWiki. HTMLDoc installed

To fix this problem, replace parent::__construct( 'PdfPrint' );

with SpecialPage::SpecialPage ('PdfPrint');

Got it working on Win2k3 and MediaWiki 1.10.1 (Finally)
Here's the solution. Copy and paste the code from above, and make the following modifications:


 * Download the latest version of HTMLDoc (which, despite the claim that it has an installer, it does not)
 * Extract the contents of the HTMLDoc zip file to C:\Program Files\HTMLDoc\
 * Add "C:\Program Files\HTMLDoc\" to the PATH environment variable
 * Set IUSR_<MACHINE-NAME> "Read" and "Read & Execute" permissions on C:\Windows\System32\cmd.exe
 * Set IUSR_<MACHINE-NAME> "Full Control" on C:\Windows\Temp\
 * Copy and paste the new PdfExport.php code from Working Code for Windows with MediaWiki v1.9
 * Change the value of $mytemp to $mytemp = "C:\\Windows\\Temp\\f" .time. "-" .rand . ".html";

That was enough to do it for me - hope this helps some of you!

~JT

Got it working with Win2k3 and MediaWiki 1.11.0
~Mark E.
 * I used the above instructions for 1.10, except the value of $mytemp indicated by JT was wrong - I have changed it to include double backslashes.
 * If it still doesn't work, try copying your CMD.exe to your \PHP folder. Make sure your PHP folder has IUSR_MACHINENAME read and read & execute permissions.


 * To make images work, I had to change line 59 from:

$bhtml = str_replace ($wgScriptPath, $wgServer . $wgScriptPath, $bhtml);
 * to

$bhtml = str_replace ($wgScriptPath, $wgScriptPath, $bhtml); because it was doubling the servername; and in line 81, I changed  to. --Maiden taiwan 20:05, 6 March 2008 (UTC)

More robust way of ensuring URL's are absolute
I've had to make URL's absolute for a couple of other extensions and found a more robust way than doing a replacement on the parsed text. Instead just set the following three globals before the parser is called and it will make them all absolute for you: --Nad 04:00, 5 September 2007 (UTC)

Nad, Is the parser that you refer to already in the php script that is on the front page? I've added those lines at the top of the file, after $wgHooks and before function wfSpecialPdf, and still no images?
 * I also tried putting those lines in SpecialPdf.execute after $wgServer; and before  $page = isset( $par ) ? $par : $wgRequest->getText( 'page' ); Still no joy. Datakid 01:31, 6 September 2007 (UTC)
 * Ideally they should be defined just before the $wgParser->parse is called in the execute function. But I've just grep'd the html output of one of my exported PDF's from Extension:Pdf Book which uses this method of "absoluterising", but it hasn't worked for the images, maybe best to stick with the current text-replacement until I sort out that problem. The replacement used to make the url's absolute is:


 * Just realised that you also need to modify $wgUploadPath to make image src attributes absolute too, but I also have a problem with images showing up even with the src attributes being absolute... --Nad 04:13, 6 September 2007 (UTC)

Newest development is to allow an arbitrary number of such repositories per installation. Since it is likely for them to have different individual algorithms to 'absolutize' their path names, it might be a good idea to rely on an image-related function for the task. Images 'know' which repository they are in, including the local file system, or the upload directory. The philosophy of image related code is to always address Image objects, and usually not deal with repositories directly. So when you find an image in the source text, get a  object, and you probably have a function returning an absolute URL right with it. If it's not there, add it, or file a bug. If you cannot do it yourself, you could also ask me to add it, and I might even do so (-; I'm dealing with image-related functions anyways atm. ;-)
 * Holla,
 * Keep in mind that,  above is highly installation dependant, and may be quite different between installations, actually, it can be any string from   upwards.
 * Keep in mind that, not every image resides in the $wgUploadPath or a subdirectory thereof. Images might be in a shared repository, like WikiMedia Commons.
 * --Purodha Blissenbach 07:55, 8 September 2007 (UTC)


 * Having had a glace at the code, I am pretty certain that, the structurally correct way is, to let the parser object take care of asking image objects for absolute URLs. That means, add a  or similar, which is likely not yet possible, but imho pretty easily added to the parser. Investigate! It may be already there. Else, see above.

Bug: /tmp/ not writeable due to openbasedir restriction.
We did not get a pdf file, but got a series of php output of the type:

Bug and Fix: Pdf Export blocks Semantic MediaWiki
We have several extensions installed, and included Pdf Export before including SemanticMediaWiki (SMW). The outcome was SMW not working: Thus the installation of SMW could not be completed. It requires the Special:SMWAdmin page to be accessed.
 * Special:Version looked as expected, but
 * Special:Specialpages did not show any of SMWs special pages,
 * URL-calling the page Special:SMWAdmin, or entering it via the seach box, yielded a "nonexisting special page" error.

Pdf Export was not working, see above. When we removed it from LocalSettings.php, we could use SMW. When we placed its call after the inclusion and activation of SMW in LocalSettings.php, SMW continued to work. See also bug 11238.

Table and image flow / Image alignment
Tables and images have all of their text forced below, as if they were followed by: Also, images that are right aligned: end up on the left side of the page and all text is forced to appear after the image. Is this a limitation of htmldoc or something that can be fixed in the extension? -- 66.83.143.246 18:53, 13 September 2007 (UTC)
 * I've temporarily fixed the image problem by wrapping them into a table, but this does not solve the general problem why htmldoc is forcing breaks after floats. 66.83.143.246 13:28, 14 September 2007 (UTC)


 * It's most likely not a limitation of htmldoc but actually the extension, probably to do with the parser sanitisation process. Comment out the line that removes the temp file and check the html in that.. Is not pretty.  Suspect

I'm running fedora c4. the htmldoc is in the /usr/bin folder.

Blue boxes on images and empty table of contents entry
htmldoc was adding blue borders on images that didn't have the frame attribute since they all had anchor tags around them and a slot in the table of contents for the mediawiki generated table of contents. I removed these with the following regular expressions in the execute function:

// Remove the table of contents completely $bhtml = preg_replace(      '/, where there should be a simple form, allowing users to try another page name, like some other special pages do, too.

Prince : A better alternative to HTMLDOC?
Is it possible to use Prince instead of HTMLDOC?

Prince seem to works the same way but it also supports CSS.

Seem to be working great with MW 1.11.0 after modifying the PdfExport.php.

 * Download and install Prince


 * Download the PHP5 Prince Accessories


 * Move prince.php into the PdfExport folder

require_once( 'prince.php' ); // make a temporary directory with an unique name // NOTE: If no PDF file is created and you get message "ERROR: No HTML files!", // try using a temporary directory that is within web server space. // For example (assuming the web server root directory is /var/www/html): // $mytemp = "/var/html/www/tmp/f" .time.

 * In PdfExport.php, add the line:
 * Remove the following section in PdfExport.php:

header("Content-Type: application/pdf");
 * 1) Write the content type to the client...


 * 1) uncomment this line if you wish acrobat to launch in a separate window
 * 2) header(sprintf('Content-Disposition: attachment; filename="%s.pdf"', $page));

flush;

 * The only major draw back is the license cost for running on server. It is only free for personal use.


 * yes... USD 1900 for academic license... too much for me :-) And HTMLDOC isn't HTML4.0 compliant (i.e. no CSS!). Thus, no PDF from wiki pages, at the moment... --GB 22:13, 26 November 2007 (UTC)

PdfExport ERROR if set User rigths
I tried to use my own MW for giving PDF file to another software. An external software passes the appropriate URL to explorer and the PDF is ready.

If user rights is default there is no problem. After I changed the user rights (see below), there is not any content in the generated PDF file, except the navigation menu on the left-hand side of the wiki's page.

I set the user rights: $wgGroupPermissions['*'   ]['read']         = false; $wgGroupPermissions['user' ]['read']        = true; $wgWhitelistRead = array("Main Page", 'Special:PdfPrint', 'Special:Userlogin',);

How can I get the whole content of the page? Can I change somehow the USER ID in the PdfExport.php? Any other solution?

Anonymous Access for Images to Work
For htmldoc to render the images it requires anonymous access

Since the file needs to be saved locally in order to remove the wiki escape characters that would otherwise cause htmldoc to fail…and the file contains absolute urls to the images.. it is in fact the server that is requesting the page.. not the user.

This is of particular importance for windows users who have enabled remote auth or alike, since anonymous access has to be disabled for these to work.

My current work around is to setup a second website under iis that allows anonymous access however only by the server's ip address, then setup a host entry that uses the anonymous site ip and the live site hostname. Then when the server goes to connect to the URL it gets anonymous access to the images and they are included in the PDF.

An alternative MAY be to setup an application pool that uses a user credential that you have setup on the wiki.. but don’t know if this will work as htmldoc is run at commandline so most likely the connection will be servername$ Suspect 06:29, 7 December 2007 (UTC)


 * Seems complicated. What I did on my site is simply put a condition in the LocalSettings file to enable authentication only if the request comes from anything else than localhost:

if ($_SERVER['REMOTE_ADDR']!='127.0.0.1') { require_once( "includes/LdapAuthentication.php" ); ... authentication code continues ... } --Guimou 03:58, 12 December 2007 (UTC)


 * Hmm, dont think that is going to work in a Windows installation, since the image references are absolute, the PHP code isnt even executed..IIS is blocking anonymous access to the images.. BTW, I couldnt get the application pool setup to work -- Suspect

Working code for MW 1.11 on Fedora 8
The code published on the "extension" page works most of the time but does not output images.

Also, on our server (Fedora 8, MW 1.11.0) the URL associated with the Print As PDF command in the toolbox sometimes has %0A tacked on at the end, and not %0D%0A as DavidJameson reported on his server.

I therefore ended up using the code in Extension_talk:Pdf_Export above as PdfExport.php, corrected line 103 to read ?><a href="<?php echo htmlspecialchars( str_replace('%0A', '', $monobook->data['nav_urls']['pdfprint']['href'] )) ?>"><?php and changed line 60 to read $bhtml = str_replace ('/images/',$wgServer . '/images/', $bhtml); as per dgrant 18:30, 25 October 2006

I can now export PDF files with images. Hvdeynde 11:04, 19 December 2007 (UTC)

PDF Link is not here
I searched for google and mediawiki, but found no hint. I am using MW1.9.3 on WAMP.


 * I tried typing manually wiki/index.php?title=Special:PdfPrint/Accueil, and it worked, ever since we did not run with rewrited urls. And direct links still not there.

Has someone a public demo so I can see what I should have in the sidebar ?

What could I do wrong so it does not work ?

Any help welcomed. I tried hacking the toolbox filling, but it was quite ... complex.

Solution: it comes from the template hook.. If your template don't use the standard call from monobook, you must change it accordingly.

Passthru unable to fork
I got a php warning saying that Passthru was unable to fork. I am running PHP and MediaWiki on Windows and IIS, and the solution seems to be giving read and read execute access to cmd.exe, which is found in the system32 folder. I also needed to make sure my web user could write to the temp folder location specified in the script.

Hope this helps someone!

String Replacement Error
So, I found a couple problems with this plugin: First off, if we have /w in the text of the article, it gets replaced with the website address, which is not proper behavior. I changed the str_replace line to: $bhtml = str_replace ('src="'.$wgScriptPath, 'src="'.$wgServer       . $wgScriptPath, $bhtml); which seems like a far more logical thing to do. I also did a $pageFile = str_replace(":", "", $page); and changed the output file in                         header(sprintf('Content-Disposition: attachment; filename="%s.pdf"', $page)); to header(sprintf('Content-Disposition: attachment; filename="%s.pdf"', $pageFile)); This causes the filename to have the semicolons removed, which is illegal on Windows for sure, and I had some trouble on OSX as well.

How to set user permissions to access this extension
Hi there, I was thinking that one possible sollution to decrease the ammount of bandwith used when used this extension could be to limit the access to it to certain users, for example anonymous or other types of users (custom users even). Is there an easy way to do this just like when you put an extension to work only with sysops (merge and delete, for instance) and avoid touching the whitelist? the example is that it should be like this -> $wgGroupPermissions['*']['pdfexport'] = false;

parsing page breaks?
HTMLdoc seems to support page breaks by inserting  but pdfExport doesnt seem to parse it or pass it to HTMLdoc.

forcing the HTML comment to show in the final rendered page either with code pre or nowiki includes the comment inline but still doesnt render properly on PDF output

...

Does anyone else have an update on this? Updating some documentation into the Wiki, and it would be useful to have some page breaks for dumping pdfs out for users

Scott.harman 14:00, 28 May 2008 (UTC)

...

Quick and dirty way of getting this to work... After the code $bhtml = str_replace ('/w/',$wgServer . '/w/', $bhtml); add the line $bhtml = str_replace ('&l_t;!-- PAGE BREAK --\&g_t;','', $bhtml);"

Remove the underscores in &l_t and &g_t. I just couldn't get them to show in the viewed page otherwise.

"??????" signs instead of russian letters
When doing export of russian language pages we have all "?" signs instead of all russian letters!!! :( Pages are in UTF-8 encoding.

Me to. How to fix it?

And me. Tried converting hmtml body to cp1251 and passing different encoding as htmldoc parameter

-- So, any way to make it work?

Solution
passthru("htmldoc -t pdf14 --charset iso-8859-1 --color ... to passthru("htmldoc -t pdf14 --charset cp-1251 --color ...
 * Edit file PdfExport_body.php
 * change two appearances of utf8_decode($...) to iconv("UTF-8", "cp1251", $...)
 * change
 * Download Cyrillic fonts from here (direct link) and put them instead of ones in /usr/share/htmldoc/fonts/
 * PROFIT!

Possible to change extension to use SkinTemplateToolboxEnd hook in 1.13
Has anyone tried rewriting this extension to use the new SkinTemplateToolboxEnd hook in MW 1.13, rather than MonoboookToolboxEnd that it currently uses?

Problems with path definitions
It took me a long while to realize why wasn't it working. I am using and Windows Server 2003 + XAMPP and it appeared that the path for the creation of the temporary file is different than the one needed for the HTMLDoc. The one for the file creation needed C:\\xampp\\htdocs\\mediawiki\\images\\; while the one for the HTMLDoc needed C:/xampp/htdocs/mediawiki/images/.

Any suggestions?

FIX: It should be: require_once("$IP/extensions/PdfExport/PdfExport.php");

I had the same problem
It was a cut and paste error

In my error logs i found: [Mon Oct 19 11:07:06 2009] [error] [client ::1] PHP Parse error: syntax error, unexpected T_STRING, expecting ')' in /usr/share/mediawiki/extensions/PdfExport/PdfExport.php on line 9 and when i looked @ line 8 a ' was missing.

Cut and paste is a terrible way to distribute an extension.

Problems with Long Line rendering
Has anyone had any luck getting this extension to not cut off long lines of preformatted text. I have some pages with generated output that is longer than can fit in typical 80-characters. If I click on the Mediawiki "Printable" page, these get conveniently resized to fit on a standard letter size paper. However, if I send the page to PDFExport, these lines just get cut off. Any suggestions would be appreciated.

Thanks, Dan

Adding Logo and current date to pdf output
Hi all,

I want to have a logo in the header of each page, which is converted to pdf. I also would like to have the current date and time to be printed in the footer. It seems to be possible if you start the conversion by the GUI of HTMLDOC, but is it also possible when starting HTMLDOC via MediaWiki?

Thankful for every kind of help!

Greeting, Stefan

Re : Adding Logo and current date
You can customize htmldoc cmd as follow :

--logoimage PATH_TO_YOUR_IMAGE --header l d

more info using man htmldoc

Re : Adding Logo and current date to pdf output
Yrs It will be usefull to have a way to customize the PDF Header with any content (wikitags ?, HTML code ? php code to request Article object data like owner, catégorie etc ?)

1k PDF on 1.15.0

Complex diagrams and Thumb-nails
Readers often expect to be able to zoom in to complex diagrams in a pdf to see the details. I would like to re-create this effect in the pdf files I generate from MediaWiki. I can achieve the desired effect by maually changing the references in the intermediate html that is used as input to HTMLDoc. The change is in the IMG tag

replace /mediawiki/images/thumb/9/99/foo.jpg/680px-foo.jpg width=680 height=477 with /mediawiki/images/9/99/foo.jpg width=100%

This has the effect that HTMLDoc picks up the original full size image rather than a thumb-nail and then shrinks it to 100% of the page width. It displays correctly and the pdf reader can zoom in for more detail.

I would like to see this included, either as a default or configurable option, in the PdfExport extension,

Specify custom CSS?
Hi.. I have installed PdfExport 2.2.2 in MediaWiki 1.15.1 running on a Windows 2000 Server, IIS server with PHP 5.2.10 and HTMLDOC 1.8.27. Everything works beautifully!!

Thanks for sharing the code, Thomas! -- Tor Arne

CSS Support in Prince
HTMLDOC does not support CSS in the 1.8 versions -- apparently this is planned for 1.9, but yet to be seen. Someone above recommending Prince, and I did some substantive re-writing of the extension source to allow me to use Prince. Works like a charm; much better quality output, and you can use CSS files. It's a little less reliable, however, and tends to throw errors on some unexpected html characters. I'm troubleshooting right now, but if there's interest once it's a little more solid I'll post my source. -- Ram

I was getting these same errors in my httpd error log, but the extension was happily producing the file (with images after I commented out the str_replace on line 57 of PdfExport_body.php since I have a virtual Apache host).

In my else stanza, I executed the same thing he would have had the variable existed but been null or 0. i.e.:

at line 83 if (isset($f)) { if ($f == null) { continue; } } else { continue; }

at line 114 if (isset($process)) { $returnStatus = proc_close($process); } else { $returnStatus = 0; } --jcw 21:15, 15 April 2010 (UTC)

I like the extension but one of the major drawbacks that I find from a user perspective is that Users have to remember the name of their article to paste it in the box at Special:Pdfprint which I think is very inconvenient. Some kind of suggestive/predictive searching would be nice i.e. the name of the article pops up automatically as you start typing it.

Area Block
Is there some way to do the equivalent of Don't print this area so that when I "Print as PDF" that part doesn't appear? --Skew 14:56, 21 January 2011 (UTC)

Fatal error: Call to a member function msg
I am running a wamp xampp installed mediawiki 1.16 on windows 2003 service pack 2, and have installed PDFExport 2.4.1 with Htmldoc 1.8.27. I have put Htmldoc.exe in the cgi-bin folder of Apache. I have put the 4 php docs in the the extensions folder under the folder call pdfexport.

I keep getting this error: Fatal error: Call to a member function msg on a non-object in C:\xampp\htdocs\w\extensions\PdfExport\PdfExport.php on line 40

Anyone have any ideas?

Image Problem Solved (for my case)
A number of people had problems with images, me too. Let me mention my solution, may it help others.

My Wiki is running https and behind a .htaccess with mandatory password. When the extension starts htmldoc it could not access the directoy where the images are stored via http(s) (which is the way htmldoc operates). Since the extension only ships PDF, there is no place for an error message.

I discovered this when manually debugging and tracing the PHP of the extension to the point where htmldoc was started. Executing htmldoc manually produced the correct error message on the command line / shell.

Solution was to adapt .htaccess in such a manner, that it was available without password when requested from the server itself.

How to install HTMLDOC ???
I will in my Wiki convert a HTML-site to a PDF-file, like on the originaly Wikipedia-site. Can someone tell me, how i have to install the HTMLDOC-files and the PDF-Expert? I f*****g don't understand the installations guide!!! Which files i need? In wich directory i have to install/unpack the files...please help me...please!!!


 * Under Linux, typically either sudo yum install htmldoc or sudo apt-get install htmldoc. Create a folder (e.g. /var/www/wiki/extensions/PdfExport/) to hold the four files listed in the installation guide. Aff 07:31, 28 March 2011 (UTC)

undefined method Xml::listdropdown
PHP Fatal error: Call to undefined method Xml::listdropdown in  /var/www/wiki/extensions/PdfExport/PdfExport_body.php on line 198


 * This extension does not work with mediawiki-1.11 (which does not implement Xml::listdropdown). Upgrade to mediawiki-1.16.2 resolved issue.
