"&" character in pagename causes page not listed in dpl
I have a DPL3 query to list all subpages within the same namespace and category = name of current page:

This works as expected, except when the pagename of the current page contains an "&". Then this list is always empty..I assume that the "&" in PAGENAME is interpreted as a logical AND? Is there a way around ?

Installation
doesn't reflect the actual naming in the source archive. It's actually named  and not.


 * I fixed the documentation. Alexia E. Smith (talk) 20:23, 27 May 2015 (UTC)

includeonly,onlyinclude tags
Is there any way to get DPL to account for these tags when it includes content through a template? --Nad (talk) 19:33, 9 July 2015 (UTC)
 * Quite possibly. Do you happen to have a working live example of where it is broken?  I can not seem to reproduce it exactly as described.  Alexia E. Smith (talk) 20:31, 9 July 2015 (UTC)
 * I just set up an example for you in my public wiki, but it's working perfectly! The problem I'm having is on an intranet so I can't show you, but it doesn't matter now as it must not be DPL3 that's causing the trouble. --Nad (talk) 14:47, 10 July 2015 (UTC)
 * Check if you have an extra opening or closing includeonly/noinclude/onlyinclude tag somewhere in the template you are working with. I have done that before and Mediawiki's parser does not produce an error.  Alexia E. Smith (talk) 20:15, 10 July 2015 (UTC)

DPL not installed on gamepedia.com
A lot of the manual examples in gamepedia.com aren't making much sense because they use actual DPL statements to show the results of the examples, but DPL isn't installed so the result of the example syntax is the same text as the example itself. --Nad (talk) 14:59, 12 July 2015 (UTC)
 * Looks like I never actually copied/ported over the examples from the old manual. The examples on the individual documentation pages are intended to be plain text.  I will work on porting and/or creating examples.  Alexia E. Smith (talk) 16:10, 20 July 2015 (UTC)
 * This is still a work in progress, but progress is being made. There were some bugs in 3.0.1 that I encountered that were actually preventing the manual from progressing forward.  Alexia E. Smith (talk) 20:14, 29 July 2015 (UTC)

HitCounters
HitCounters were removed in 1.25 and moved into an extension. Since installing the extension deletes the relevant tables, which is also scheduled to happen in 1.26 for all installs, reports that use the counters throw database errors. -- Prod (talk) 02:00, 21 July 2015 (UTC)
 * The new release of Extension:DynamicPageList3 supports the HitCounters extension now and resolves this issue. Alexia E. Smith (talk) 20:14, 29 July 2015 (UTC)
 * It doesn't seem to be working for me. I got the following error: Unknown column 'hit_counter.page_counter' in 'order clause'. -- Prod (talk) 02:22, 11 August 2015 (UTC)

suppresserrors/debug, undefined variable
Many thanks for this great re-work! DPL has become so essential to my wiki that I went through the trouble of upgrading to MW 1.24 and lifting PHP to 5.4. I am truly glad to see that this extension is being maintained in good hands.

I am using version 3.0.2 which I cloned via Git IIRC. Two things I noticed:


 * 1) Instead of "suppresserrors = true" I had to set "debug = false" in addition.
 * 2) There seems to be a small bug in the code for I am getting "Notice: Undefined variable: where in /var/www/extensions/DynamicPageList/classes/Query.php on line 1816".


 * I am looking into suppresserrors/debug issue. However, the PHP notices are fixed as of: https://github.com/Alexia/DynamicPageList/commit/3b8c52336cde5c444e7cd21d675d1dc802b681c0  Alexia E. Smith (talk) 15:23, 31 July 2015 (UTC)
 * Took a few minutes to figure out, but the issue with suppresserrors is that it is deprecated. Setting noresultsheader to a blank space will have the same effect of suppressing errors for queries.  Alexia E. Smith (talk) 15:43, 31 July 2015 (UTC)


 * Many thanks for your quick response! In my original request I forgot to mention that the wiki page about suppresserrors mentions debug but that is a red link. It would be great if that could reference could be completed. Cheers! --Sm8ps (talk) 19:29, 31 July 2015 (UTC)
 * I just went though and fixed several on that page. Thanks!  Alexia E. Smith (talk) 19:47, 31 July 2015 (UTC)

dplcache parameter
When is going to be introduced a replacemenet for the 'dplcache' parameter? Or is there already one? The documentation on gamepedia says that it's being worked on. Is there a release date or... ? 188.24.73.36 14:22, 15 November 2015 (UTC)
 * Whoops, that should have been removed from the documentation. The dplcache parameter was added in DPL2 and I removed it when creating DPL3.  The cache functionality is now fully handled by MediaWiki's built in cache system and there is no need for it anymore.  Alexia E. Smith (talk) 17:35, 15 November 2015 (UTC)
 * Hmm, then how can I make it so whatever it's displaying (images in my case) changes only once per day and not every time I reload the page? I am using both  and  . 188.24.73.36 13:48, 16 November 2015 (UTC)
 * Allowcachedresults=true is the default. Caching is is explicitly turned on and has to be disabled(set to false) in DPL3 so it is not needed to specify the allowcachedresults parameters.  This is opposite of DPL2.  The usage of cacheperiod is still correct, but you have an extra zero for the number of seconds.  Otherwise the default is one hour.  Alexia E. Smith (talk) 15:07, 16 November 2015 (UTC)
 * Welp, I have removed both the extra zero and the unnecessary parameter, but it's still showing a different image each time the page is reloaded. Is there a tag that makes it change the image only once per day? Also, does this separator  separate titles both in 'notcategory' and 'nottitlematch'? 188.24.73.36 16:29, 16 November 2015 (UTC)

So, will you answer me? 92.82.28.212 17:05, 27 November 2015 (UTC)

Setting $allowUnlimitedResults=true makes no change of count limit of 500
I want to count the number of members in a category by using

.

The category contains more than 500 members, so I set $wgDplSettings['allowUnlimitedResults']=true; in LocalSettings, but I only got 500 again.

Setting $wgDplSettings['maxResultCount']=10000; and $wgDplSettings['allowUnlimitedResults']=false; in LocalSettings... the same 500.

Setting $wgDplSettings['allowUnlimitedResults']=true; in LocalSettings and the parameter "count=" in the #dpl-command above... the same 500.

I got the correct count by editing ParametersData.php the value for 'count' 'default'=500' in a higher value say 10000.

The two DplSettings above left to standard ("false" and "500" respectively). I'm using the latest DPL-version 3.0.9 and MediaWiki 1.25.3.

Can someone please check this. Thanks. Karsten 192.53.103.119 11:13, 6 April 2016 (UTC)

Conflict b/w Extension:Lockdown and Extension:DynamicPageList3
Hi all, there seems to be a conflict between Lockdown and DPL3 in cases where you have custom namespaces defined that are locked. In such cases DPL neglects selection of all pages that reside in locked namespaces. Though in LocalSettings.php
 * nothing is set for  thus principally allowing transclusion and
 * is set to default value null hence allowing all namespaces for DPL.

Example: let Secure be a custom name space that has been locked down for everyone except sysop. Sysop executes following dpl code:

This renders message: Extension:DynamicPageList (DPL), version 3.0.7: Warning: No results. though Secure has several pages.

Any ideas?

Switching from previous version
The wiki MoBaDaten.Info ist still runing with the DynamicPageList (third-party) extension. The introducing note of the DynamicPageList3 extension promises fully backwards compatibility. If I want to switch from that “ancient” version to this revised version, I only have to do the following steps: --Wgkderdicke (talk) 13:56, 23 June 2016 (UTC)
 * 1) Upload of the DynamicPageList3 extension into the extension folder
 * 2) Change of the require_once statement in LocalSettings.php (wiki is still running with Mediawiki 1.23)
 * 3)  without any unpleasent surprises afterwards …???

List is not going to update?
I installed DPL3 for lastedit list in main page. But I got a problem that list will not refresh by itself.

The list content will keep as no change since I edited it. Refresh, logout, close window is not going to change anything.

Anytime I edit the settings in LocalSettings.php or edit the code, then list will update. Any possible reason?

Here's my code:  category = ABC addeditdate = true ordermethod = lastedit order = descending count = 10 

Additional question:

1. When I set namespace = 0, which should display content from main space. But I got this error:

Extension:DynamicPageList (DPL), version 3.0.9: 警告: 錯誤的 '$0' 參數: 'namespace'! 正在使用預設值: '0'. 說明: $0= $3.

2. When I tried to use firstedit as ordermethod, the result is totally the same with lastedit. Is it a bug? How to fix it?

Thanks for reply! --JHK (talk) 02:09, 18 August 2016 (UTC)

I'm having the same problem. Also, according to gamepedia there should be a randomseed parameter, but when I use it it just says the parameter does not exist...118.212.157.16 01:48, 7 October 2016 (UTC)

"shownav" style ("next 100") navigation bar for list generated by DPL
I would like to use DPL to generate a list of recently changed pages. List can run into 100s of entries. I would like to put a navigation bar like the one that is automatically generated by Special:NewPages. Generate links like (Newest) (Newer 100) (Older 100) (Oldest). Clicking on these links, DPL should generate a list of relevant set of pages. Can this be done? Can you show me how? Size of list is not predetermined.

How do you exclude lastedits when the edit was done by bot?
We have a DPL query which shows the date/time of the last edit on all our Talk pages, a link of the person who last edited the talk page, a link to the corresponding main page and the value of the (SMW) property Editor on the corresponding main page. We recently had bot activity (from extension:MassEditRegex) that made updates to the talk pages and now all these last edits from bot are listed. So I want to 'not see' any edits from bot, similar to hiding updates from bot on Recent Changes. I was looking at something like using, but that doesn't give the desired result. Any ideas?

DPL: "**" will add all DIRECT subcategories of that category DB ERROR
When adding the asterisk to a category in the DPL parser function to add search in subcategories I always get an error: A database query error has occurred. This may indicate a bug in the software. Fatal exception of type "Wikimedia\Rdbms\DBQueryError" The code can be as simple as :

Any hint of why this might be and how to solve it? Or how to search in subcategories of the current one? Thanks,

It can easily be bypassed by calling DPL recursively:

Gallery tag stops the processing of Format special symbols
The example in the documentation:

DOES work producing a Gallery with three photos.

In the test I have done, it seems that as soon as DPL encounters the tag it stops processing as symbols the following characters so there is no way to pass to the Gallery the resulting list of pages.

As it is in the documentation... did it ever work in previous versions?

Any workaround available for this great functionality?

YES: The workaround is as simple as using the Escape characters of DPL. The following code works:

I have corrected the mistake in the documentation.

runtime error with MW 1.29 (Cite extension conflict)
The code in DPL.php near line 80 tries to access private variables from the Cite extension to avoid that citations get lost that were made before DPL is called. The php interpreter does not allow such kind of access and you will get an error message which blocks the whole wiki installation. As a quick work around you can disable the workaround. In the long run the conflict should be solved via API calls to Cite.php (if this is possible). Algorithmix (talk) 20:46, 3 August 2017 (UTC)

original documentation is available again
I (Algorithmix aka Gero) am the author of the original manual (and of large code portions of DPL). Unfortunately the website with the manual was down for some time due to a PHP version change. I migrated the manual to another server (the old link to http://semeb.com/dpldemo still works) and upgraded the MW version to a more recent one.

User accounts that were valid for the original website should still work.

I noticed that there is a (partial) copy of the manual at "gamepedia". In case the version at gamepedia contains some updates/corrections: How should we proceed?

ordercollation has no effect
According to this page (https://help.gamepedia.com/DPL:Parameters:_Controlling_Output_Order) I set ordercollation=latin1_german_ci to have a non-case-sensitive ordering of my results, but the list is still ordered by case (uppercase first, lowercase second). What am I doing wrong?

List the page itself
When I add a category based search (e.g. category = A) on an page B, that is also in category A, then page B is not listed in the results. I think this is for the most cases very helpful, but I need page B listed. Is there an option for doing that?

How to show only the pagenames,and suppress display of matched parameters, while still matching the parameters?

Johnywhy (talk) 08:42, 5 June 2018 (UTC)


 * Solved. use #dplreplace to remove the matching text put there by the include statement. Use the format statement only to append an arbitrary delimiter character before the output of the include statement, to ensure dplreplace doesn't accidentally affect any page-names (in case any page names contain the same string). The format statement isn't normally required-- page-names will get listed in the output by default. I use · as delimiter, but it can be any character you want. Note The format statement isn't normally required-- page-names will get listed in the output by default. The format parameter by itself it's insufficient to remove the matching text, because the matching text is added to the output (by the include statement) after the output of the format statement. The format statement has no effect on the output of the include statement.
