MediaWiki Version
This page says that DPL requires v. 1.7+ of MW, but the DPL wiki says 1.8+. Would be worth changing to whichever one is correct! I tried to install with 1.7 and it didn't work, which was disappointing. --16 November 2007

Conflict with RSSReader Extension
I've noted a conflict between the RSSReader Extension and DynamicPageList Extension when both are run on the same page. See Comment on RSS_Reader Extension for details. Any idea why this might be?

Labeled Transclusion Sections with DPL 1.6.9
We just installed DPL 1.6.9 and noticed that our section transclusions are no longer working.

For example, we have

title=Article1

include=summary

And it used to work with the previous DPL version which displayed all text in the summary section but with DPL 1.6.9 nothing is being picked up. Any ideas? -alhui

 * Add the following after the line with inclusion of the extension in the file LocalSettings.php

$wgParserConf['class'] = 'Parser_OldPP';


 * This will force the mw-core to use the old parser. Jeblad 15:13, 13 April 2008 (UTC)


 * Having same problem and the OldPP hack doesn't seem to solve it. (MW 1.12; DPL 1.6.9; the labeled section extension has been deactivated, and the dpl2include seems to work because the "section" tag is listed in my MW spectial:version page). A page called Test1 with the text The book is Cien anos de soledad is never transcluded in a page Test2 with the code Nothing is output. The older version 08:32, 17 January 2008 works perfectly though. --Fxparlant 09:55, 14 July 2008 (UTC)


 * Try DPL 1.7.4. It runs on MW 1.12 and 1.13 as you can see on the dpldemo website. If you still have a problem, please demonstarte the effect on that website and we will have a look at it. 84.58.229.59 09:51, 27 August 2008 (UTC)

Problem with mediawiki 1.12
It seems that message file cause error on mediawiki 1.12 (see this thread). Could author of this extension make the update for us ? -- phkoech 26 april 2008


 * The dpldemo website is now running on MW 1.13. All problems should be solved. 84.58.229.59 09:48, 27 August 2008 (UTC)

labeled section only
How to list only the labeled sections, without the pages not containing the section: will list the pages of category Book, even if they do not have. The includematch cannot be used, because the include doesn't call the whole section, but only the content of the section tags. Any idea ? --Fxparlant 11:06, 14 July 2008 (UTC)

Catch a template parameter
I am looking for a way to use DPL to catch, not the title of a page, but the parameter of a template:

if a page calls the template  , how to catch the param3 in another page, with a query on the first parameter and the second ?

--Fxparlant 13:08, 7 August 2008 (UTC)


 * You can use phantom templates for that purpose. DPL will call the phantom template instead of the original one and pass all parameters to the phantom template in the same way as they were passed to the original template. And within the phantom template you can do whatever you like - which means that you can simply output the third parameter.


 * See the DPL manual for details. 84.58.229.59 09:47, 27 August 2008 (UTC)

New pages
Is there a way to get this to only return new pages (the pages in Special:Newpages)? Thanks 193.36.230.96 12:13, 17 August 2008 (UTC)

Hi,

Is there a way to get DPL running on a Mediawiki 1.6.9 ? If not, why exactly ?

download from subversion
Can the download used the inclued mediawiki subversion system ? Crochet.david 19:00, 14 September 2008 (UTC)

Currently the latest version is on the dpldemo page. But this will change in the near future. Mediawiki SVN repository will become the official source for distribution. Algorithmix 09:22, 21 May 2009 (UTC)

Tweak to make DPL backward compatible with DynamicPageList2 parameter
I'm one of the admins at ChoralWiki (www.cpdl.org), a free Public Domain scores library, and we use DynamicPageList2 a lot in it with parameter set to 'true'. We were doing an upgrade test to the newest version of DynamicPageList and after the upgrade all our DPL queries started showing this warning:

%DPL-1.7.4-WARNING: Unknown parameter '$0' is ignored. Help: available parameters: suppresserrors.

After a quick research we realized that parameter is no longer supported by the new DPL versions. It would be a pain to edit all pages where it appears, so we decided to tweak the DPL code to recognize it and behave as expected. We made the changes below, tested it and it worked fine. So we decided to post it here in case someone else faces the same problem. All one needs to do is to add the following lines in red to file DinamicPageList2.php:

line 682:

/**        * noresultsheader / footer is some wiki text which will be output (instead of a warning message) * if the result set is empty; setting 'noresultsheader' to something like ' ' will suppress * the warning about empty result set. */       'suppresserrors'       => array('default' => 'false', 'true', 'no', 'yes', '0', '1', 'off', 'on'), 'noresultsheader'     => array('default' => ''), 'noresultsfooter'     => array('default' => ''),

line 1157:

$bSuppressErrors = self::argBoolean(self::$options['suppresserrors']['default']); $sResultsHeader  = self::$options['resultsheader']['default']; $sResultsFooter  = self::$options['resultsfooter']['default'];

line 2095: case 'noresultsheader': $sNoResultsHeader = $sArg; break; case 'suppresserrors': if( in_array($sArg, self::$options['suppresserrors'])) { $bSuppressErrors = self::argBoolean($sArg); if( $bSuppressErrors ) $sNoResultsHeader = ' '; }                   else $output .= $logger->msgWrongParam('suppresserrors', $sArg); break; case 'noresultsfooter': $sNoResultsFooter = $sArg; break;

After the change, if is used in the query and 0 pages are returned, it won't show any warning message; if  is also used, it will show the 'text' supplied. Capmo 13:40, 18 September 2008 (UTC)


 * Since release 1.7.5 suppresserrors is part of the official DPL distribution. Algorithmix 09:20, 21 May 2009 (UTC)

Index (List of index-terms) for a book
I am experienced in editing wikipedia-articles. Now I want to use mediawiki on my server to write a book (around 1.000 articles). I want to mark index-terms in articles and have one page with a sorted index. The book will exist of 1.000 articles. So it is no problem to generate the article dynamicaly when I will open the index. Is DPL the right extension to do the job?

How to mark the index-terms in articles? Which -code do I need?

Or is there a better solution than DPL? Regards, jan--89.52.155.34 23:55, 13 January 2009 (UTC)

I made a beginning:

I have a template template:Index and call it in articles with with

For the output of the whole Index I have an article with: uses=Vorlage:Index include={Index}:1 table=,articletitle,keyword It works!

How can I get an output in an alphabeticle order like this? keyword-1 ..... articletitle 1 ..... articletitle 2 ..... articletitle 3 ..... articletitle ...

keyword-2 ..... articletitle 4 ..... articletitle 5 ..... articletitle 6 ..... articletitle 7 ..... articletitle ...

keyword-3 ...... ...

 * For me the answer is no longer important. I now use Semantic Mediawiki - takes longer to understand but is the future.
 * I don't delete the question - maybe someone else is interessted in the answer.
 * Regards, Jan


 * Hello Jan, creating a permuted index is a challenge because DPL normally walks sequentially through all articles which match the selection criteria and collects the desired information (in your case template invocations). In your case one would have to store the collected data (using the arrays extension ), re-arrange the order and then produce the output in a final step. With less than 10 lines of code all this is possible:
 * see     http://semeb.com/dpldemo/index.php?title=DPL_Example_017 
 * I know SMW and think it is powerful for expert users. The idea of DPL is to use MW as it is without introducing new syntax for those users who write articles.
 * Is your book publicly avaialable? If yes, please give a link. Algorithmix 09:32, 21 May 2009 (UTC)

Problems
Hi. I have a problem with labeled section transclusion, the section tags show up along with the transcluded text. This problem only showed up recently; the page was doing fine four months ago when I left it. When I came back a few days ago, no changes have been made to the articles but the DPL pages have broken formatting. It is a Wikia page and I asked the Wikia staff about it too, but they haven't recognized something from their end being the source of the problem either. So here's the problem. Instead of this:

http://img.photobucket.com/albums/v59/daarklord/ForumGraphics/DplWtf01.gif

I get this instead:

http://img.photobucket.com/albums/v59/daarklord/ForumGraphics/DplWtf00.gif

My wiki can be found here. The formatting error can be seen here.

Please help. Thank you.

I installed the extension on a private wiki according to the notes on the page (#include("$IP/extensions/intersection/DynamicPageList.php");), but it doesn't work. When I disable (commtenting out) the extension in the localsettings.php, I can see the page. If I enable the extension I only get a white page displayed on pages with , all other pages can be edited and shown.

 * Can you please download the latest version and test again? There was a major problem in the logic of DPL which dealt with the inclusion of "labelled sections" ... Algorithmix 09:34, 21 May 2009 (UTC)

Documentation?
This article would be more helpful if it actually explained how to use this extension, rather than simply listing what it's capable of.


 * The article gives a link to the manual. I bet that the manual contains more information than you ever will want to read about DPL ;-)

License for DPL
The wiki page for DPL says 'no license specified' the source code of the program has one file without any license, another with GPLv2+ and another that just says GPL. Could this please be made consistent? I would like to package DPL for Fedora.

Undefinde Variable
Wiki: 1.13.5

PHP: 5.0.5

Apache: 2.0.54

I have installed MediaWiki version 1.13.5 and included the extension dpl. Now I got on my main page this notice notes:

Notice: Undefined variable: result in D:\xampp\htdocs\Lukas\wiki113\includes\Title.php on line 1161

It's a liitle bit strange, because the extension works, but the notes are little bit annoying. What can I do now, has got someone an idea?

 * This should not happen! Are you sure that the error comes from DPL? I have never heard anyone reporting something like that. I suggest the following: Make a clean new test installation of Mediawiki, use DPL as the ONLY extension and then try to reproduce the error. If it still shows up, write a bug report and I will look after it.
 * BTW: Sometimes new MW versions introduce new errors. The dpldemo wiki runs on 1.13.0 Algorithmix 09:44, 21 May 2009 (UTC)

Section inclusion does not work
I noticed that section inclusion does nothing. In my wiki, as well as on the DPL demo wiki. See the section inclusion test page: it does not output the contents of the sections. It this broken? Using latest MediaWiki and latest DPL. My test page: http://www.jacmoe.dk/wiki/index.php?title=Conditional

Warning message
How can I remove the %DPL-1.7.6- in front of a warning message? The problem is this added in front of the MediaWiki message and I can't find it in the core code. When there are no results I want it to display nothing. --Subfader 12:02, 28 April 2009 (UTC)
 * Found it: return ' %DPL-' . ExtDynamicPageList2::VERSION . '-' . --Subfader 12:49, 28 April 2009 (UTC)
 * Yes, you can remove the prefix in the php source code. It is hard-coded there.
 * You could use suppresserrors=true to suppress the error message complaininig about an empty result set. Algorithmix 09:48, 21 May 2009 (UTC)
 * Yep, I found out about suppresserrors=true later which is the better solution, nontheless I think the %DPL- in fron of the messages are useless. Maybe remind the user that a DPL code is there. --Subfader 11:08, 21 May 2009 (UTC)

A Bug?
I use DPL together with MediaWiki 1.14.0, SMW 1.4.2, DPL 1.7.9 If I follow a link, that is done by the Call-Extension, the CSS-File of SMW is not included. What can I do? The main problem: The field “smwsortkey” is not more hidden, because the style for it is not included. Christian Weiss 14:44, 27 May 2009 (GMT+2)


 * Please give more details. I assume that the problem has nothing to do with DPL; this means that it also occurs if you use the Extension:Call from the browser's URL-line or within a normal document like this Special:Call/:Mypage,a=b . I don´t understand your remark about a "style". Are you talking about css? Can you reproduce the error on the dpldemo website? It has DPL 1.7.9 and SMW 1.0 installed. Algorithmix 16:11, 27 May 2009 (UTC)


 * The name of the extension is changed and this will create a lot of confusion about which extension infact has the bug. Jeblad 04:03, 31 May 2009 (UTC)


 * It's like you said: I call a Template by the Call-Extension, the DPL-Calendar ":Current events" for example. If it's included the normal Way in a Page, in the HTML-Source the "SMW_custom.css" and the "SMW_sorttable.js" are included. If the Template ist called by the "Call"-Extension those files are not included in the HTML-Source. A workaround ist to include those files in the Common.css and Common.js for Skins, so it is included everytime. For the SMW_sortable.js I get then 2x sortbuttons :-) I think, the Call-Extension ist part of your Pakage, so I write my Problem to you. Christian Weiss 10:06, 06 Jun 2009 (GMT+2)

LoF
I sthe LoF ment to be set as global in LocalSettings? I'd prefer it as option per DPL call. So I want to use a complex DPL call I would set LoF = 3 or sth inside the call. But if I want to run a very simple call I would set LoF = 0 to save some ressources. --Subfader 15:15, 17 June 2009 (UTC)


 * Currently the Level of Functionality is a configurable option which is global for the whole use of DPL in a wiki. It is meant to be a "protection belt" against abuse. I try to anticipate the aguments of those people who must be convinced to run DPL on a website lime WIKIPEDIA. Any suggestion which opens this path is welcome. I guess there will be some user rights administration component in the end - although I do not like this idea very much. --84.58.224.247 21:43, 1 July 2009 (UTC) (Algorithmix)


 * kk, thanks for the explaination. I thought it's mainly to make it faster. --Subfader 05:52, 2 July 2009 (UTC)

DPL Doesn't Work after MW Upgrade from 1.13 to 1.15.1
Hi, I have a private wiki we use as a content Management system at work. I updated the wiki from MW.1.13 to MW.1.15.1, and suddenly DPL doesn't work. For example, I have a page for each of our main applications, with a supbage called 'Troubleshooting'. Below that are more subpages, one for each troubleshooting document. The '/Troubleshooting' subpage consists entirely of DPL to list the child subpages for a user to browse and jump to.

For example (changing the page names to protect proprietary information):

We have a set of pages like so:

* Main:Zazaza * Main:Zazaza/Troubleshooting * Main:Zazaza/Troubleshooting/Error 51 - File not Found * Main:Zazaza/Troubleshooting/Can't Save Configurations * Main:Zazaza/Troubleshooting/App Crashes if User Chews Bubble Gum

The top page, Main:Zazaza, describes the application and has a link to Main:Zazaza/Troubleshooting.

Main:Zazaza/Troubleshooting consists entirely of DPL code that will list the three 'troubleshooting' child subpages with links. This page's DPL Code is as follows:

 

titlematch=Zazaza/Troubleshooting/%

notnamespace=Image

notnamespace=Image_talk

notnamespace=Template

notnamespace=Template_talk

replaceintitle=/.......Troubleshooting./,



Previously, the DPL worked, and a user browsing to the Zazaza/Troubleshooting page would see a list of clickable links:

Error 51 - File not Found Can't Save Configurations App Crashes if User Chews Bubble Gum

Now, since the 1.15.1 upgrade, all that shows up is the following:

Extension:DynamicPageList (DPL), version 1.8.6 : 

Before you ask, no, there is no log being generated or updated anywhere within my wiki home that provides me with a clue as to why DPL isn't working.

I confess to being confused because when I originally downloaded DPL in May or June 2008, this was during the time frame that "old DPL" was known as "Intersection" and 'this' DPL was just known as "DPL", and at the time there wasn't even a reference to the forked versions on the extension page. (I only came to learn all of this with my research this past week.) However, I have verified that I am using semeb.com's Dynamic Page List (was using v.1.6.9, now using v.1.8.6.)  I downloaded v.1.8.6 earlier in the week from http://svn.wikimedia.org/svnroot/mediawiki/trunk/extensions/DynamicPageList/, and I just re-obtained the files from the ZIP archive available at http://semeb.com/dpldemo/images/f/fe/Semeb_extensions.zip and redeployed them to be certain. The behavior is still the same as above.

Any help would be appreciated. --ApostleGreen 23:12, 16 July 2009 (UTC)


 * DPL doesnt' work with MW 1.15.0 or MW 1.15.1 and DPL 1.8.6
 * DPL doesn't display anything, but I've to follow up the last Message from ApostleGreen.


 * The only output is:

Extension:DynamicPageList (DPL), version 1.8.6 : 
 * Please, this is a great extension, could anyone help us?!


 * Many thanks in advance!!! Timotheus.elias 07:43, 17 July 2009 (UTC)


 * Are you sure about all this? It worked fine for me in MW 1.14 and now in 1.16 alpha (I skipped 1.15). So you could still upgrdae to 1.16 alpha but actually I think something else is wrong on your wiki. --Subfader 10:57, 17 July 2009 (UTC)


 * Hi Subfader, I tried 1.16 alpha, but it has a conflict with an other extension, so I must use 1.15.1 for now.
 * The example DPL Code I used in my page:

 |titlematch=Basis:Mike3 |include   = * </DPL>
 * This are my used extensions:
 * GroupPermissions Manager
 * PdfExport
 * PdfBook
 * SimpleSecurity
 * wiki2xml extension
 * FCKeditor
 * Lockdown
 * Thank you!!!
 * Timotheus.elias 12:49, 17 July 2009 (UTC)

Well, your example code is wrong. It's either  titlematch=Basis:Mike3 include   = * </DPL> or Which is the other conflicted extension? --Subfader 13:28, 17 July 2009 (UTC)


 * I have the same problem. After upgrade from 1.13.3 to 1.15.1 the extension stop working. I've update extension to 1.8.6, but it doesn't help. --Dnikitin 19:11, 17 July 2009 (UTC)
 * It seems I fix my problem. Originally my code was

count=50 namespace=Image ...
 * After I replace Image with File the extension starts working again. --Dnikitin 22:22, 17 July 2009 (UTC)
 * Yep the Image namespace was renamed to File in MW 1.14. It needs to be replaced in all DPL calls. Still it works with old [[Image:...]] tags. --Subfader 23:11, 17 July 2009 (UTC)


 * Thank you very much vor your quick answer. Now, after I installed your extension correctly :), I'm able to include other pages that are not protected
 * by the extension Lockdown. Pages in the namespace I've locked with Lockdown extension are not includeable and there will be come following message:

Extension:DynamicPageList (DPL), version 1.8.6 : WARNING: No results.
 * When I call the following


 * I'll get all Article's there are not in the extra namespace "basis" and "public". Why is this so?
 * Although I don't enable Lockdown extension, there'll be the same result!
 * Many thanks! Timotheus.elias 13:41, 20 July 2009 (UTC)
 * The problem was fixed, the Wiki Parameter $wgNonincludableNamespaces was set and therefore this wasn't included. Thanks a lot for your great extension!!! Timotheus.elias 14:06, 20 July 2009 (UTC)

Parsing Pipes
I have run into a little bit of a quandary which I am trying to solve. I am trying to create a template with a set of parameters that are passed from a dynamically created list from DPL. However, when using the pipe character in the formatting for DPL like this: ...the pipe character is not parsed by the templating system, I think because of the order in which things are processed... The result is all the articles listed like this: "|Article1|Article2", and so on, instead of passing each one as a template parameter. I have been trying, but I can't think of a way around this. Does anybody have any thoughts on this? --Bsmithme 21:12, 18 July 2009 (UTC)
 * I have tried using subst:Hot_issues but that had no effect. I've also tried creating a template with "|", but that didn't work either.  I think I am approaching it wrong...--Bsmithme 21:15, 18 July 2009 (UTC)
 * Try ¦ --Subfader 21:16, 18 July 2009 (UTC)
 * No luck there. I think ¦ is only used when you are using #dpl and need a pipe in the dpl parameters, but I'm not sure (versus  where you can use pipes with impunity). --Bsmithme 21:29, 18 July 2009 (UTC)
 * Dunno your template but shouldn't it be {{Hot_issues without | cos that will be return in front of the first result already. Try

{{#dpl: }}
 * notnamespace=Category
 * category=Application
 * category=Hot_issues
 * format=²{Hot_issues,\n¦%PAGE%,,}²
 * Finds only pages in cats Application AND Hot_issues. Also %TITLE% doesn't make much sense to me when should find pages from all namespaces except subcats. If it doesn't help post your template here as I can't image what you try to do there by sending an unknown ammount of parameters (each page link) to the template. --Subfader 22:15, 18 July 2009 (UTC)
 * Think the best way to illustrate what I'm trying to do is this:

{{Hot issues }} So that the page calling the hot issue template is automatically populated based on the results of the DPL query. I'm starting to think it might not be possible to do it this way. --Bsmithme 23:45, 18 July 2009 (UTC)
 * DPL result 1
 * DPL result 2
 * and so on
 * Oh, but you are on to something with your suggestion and I think I can get it to work with some more fidgeting. --Bsmithme 23:52, 18 July 2009 (UTC)
 * Aha! I got it with this:

{{#dpl: }} Thank you so much for your assistance, Subfader. --Bsmithme 23:56, 18 July 2009 (UTC)
 * notnamespace=Category
 * category=Application
 * category=Hot_issues
 * format=²{Hot_issues,¦%PAGE%,,}²

Fatal error: Unsupported operand types in %wiki-path%/includes/parser/LinkHolderArray.php on line 33
After upgrading my wiki to MW 1.15 I got the error message: Fatal error: Unsupported operand types in /home/schlott/public_html/wiki/includes/parser/LinkHolderArray.php on line 33 and the extension stoped working.

The solution was inside the DynamicPageList/DPL.php with the following statement in Line 36: // cloning the parser in the following statement leads in some cases to a php error in MW 1.15 // You must apply the following patch to avoid this: // add in LinkHoldersArray.php at the beginning of function 'merge' the following code lines: //		if (!isset($this->interwikis)) { //			$this->internals = array; //			$this->interwikis = array; //			$this->size = 0; //			$this->parent = $other->parent; //		}

After adding the mentioned code lines to LinkHoldersArray.php the extension works just fine. -- Flaming Moe
