Error after Xampp-Upgrade
PHP 5.3 seems to be more strict with handing over of values/references. In this case the culprit probably is Language.php. see Try to change

-	function getMagic( &$mw ) {

+	function getMagic( $mw ) {

in Languages.php and your problem might be solved.

Good news! I upgraded to MediaWiki 1.15.1 and the concurrent version of the extension and that solved my problem.

--Katwol 10:11, 18 August 2009 (UTC)

After Upgrading from Xampp 1.7.1 to 1.7.2 I get the following error messages when the CategoryTree-extension is activated in LocalSettings.php:

A little mistake at saving in RichEditor
When saving a page in RichEditor (MW 1.15, IE8), there is a small change that causes Categroytree not working.

From this:

It makes this:

Currently this generates a list that are subcategories to the category "features". But the output of it is in a single column, which can get very long if there is a lot of subcategories underneath "features". Is it possible to format the output so the list is in multiple columns? Also, can it be done so it's arranged alphabetically (like the subcategories list generated automatically by the wiki itself -> this is actually the desired output i am trying to get) Thanks in advance!! 128.189.248.8

Different spot in sidebar
Is there any way of making this be above some of the other items in the sidebar? - My Wiki

--38.98.7.10 02:45, 7 March 2009 (UTC)

Go into:

MediaWiki:Sidebar

Put * categorytree-portlet into the list anywhere you want.

72.166.192.10 17:26, 27 April 2009 (UTC)

This doesn't show any effect in my Wiki. Why?

UNIQ385ee6e553c2262-h-0--QINU
An error occured in German Wikipedia. The heading of section appear e.g. as UNIQ385ee6e553c2262-h-0--QINU (cf. QINU fix). This happens if the tag missing category appears on the page (example). --WIKImaniac 19:59, 6 January 2009 (UTC)


 * This also happens in hebrew mediawiki with this extension. --85.250.59.208 09:42, 24 February 2009 (UTC)


 * Same problem in my wiki in French www.wikitau.org see http://www.wikitau.org/index.php5/Portail:Histoire but strangely not in http://www.wikitau.org/index.php5/Portail:Personnages see Extensions_FAQ FrViPofm 10:31, 3 March 2009 (UTC)


 * Same problem in my german wiki. It's very strange. In some case it work without QINU errors, but in other case it dosn't work. That's approximately 50% of cases. What is the Problem? I have test it with version r46794 (Current) and r45462 (version for mediawiki 1.14.0). P. Vizeli 11:09, 4 March 2009 (UTC)


 * Same problem in MediaWiki 1.15.1 on Php 5.3.0 in situations where the category tree cannot be found (typo in the category named inside of the tag). No problem, if category can be found.

A request
Is there any way a switch can be added that will allow the function to be set to default to the collapsed state? I am referring to the function. --Jerem43 06:13, 22 January 2009 (UTC)


 * I'm using a very crude workaround. In wikia there is an js extension that is used to collapse / expand blocks, so what did I do? Nested the categorytree inside a Show/Hide container. http://dev.wikia.com/wiki/ShowHide


 * If you set depth to zero it will only show the root element. 75.119.248.55 13:53, 3 August 2010 (UTC)


 * yes but it show only the root element and when you click on the [+] it sais "loading" and don't show the subcategories...

A different display
Please take a look at en:Category:Application software. The category outline there was designed as a concise display of the category tree, intended for use by people categorizing articles and not knowledgeable of the existing categories. While that outline is hand-coded (and took advantage of some unique characteristics of that category), the rules for generating it were:
 * 1st level categories start a new line and are visually distinct (bold/higlighted/...)
 * 2nd and lower level categories follow on the same line without any indication of level
 * a category only appears once, whether the prior appearance was as a 1st or other level makes no difference
 * in general (it was hand-coded) the maximum depth was 4.

The resulting "outline" makes locating categories quick, usually at a glance. For many uses, it's not the tree structure that is important, but category existence, and the "outline" makes tree walking, expanding branches, unnecessary. Please consider such a display for future revisions. tooold00:36, 29 January 2009 (UTC)


 * Surely then if that were the case - you wouldn't be using Category Tree - which people are choosing to use because thats what they really want. Its a nice layout indeed, but we use Category Tree in the sidebar where such a layout would not function at all.

CategoryTree Does not show any Categories
Hi,

My wiki does not show Category Tree, eventhough it has categories. The categories pagge displays

Pages in category "Agile" There are 3 pages in this category.

A Agile Challenges Agile Resources Agile Testing

But when i click on Show Tree it shows:"Category Agile not found "

 * Hurrah. Bennylin 09:42, 9 April 2010 (UTC)

parameter DEPTH
Depth requires only 1 number, but the default is shown as "1,0". A description would be nice, rather than our having to experiment. 69.106.246.15 19:30, 20 February 2009 (UTC)
 * The depth is just 1 number. The description did read: "Default is 1, 0 means only the root node." I changed to remove the confusion - "Default is 1. 0 means only the root node." GarethLewis 05:11, 21 January 2010 (UTC)

Category Page Trees only show subcategories, not pages
It took me a while to find $wgCategoryTreeCategoryPageOptions because it's not so obvious that this is the needed option. I searched google and found an old talk page for this extension which showed a few hacks to fix it. Anyways I finally did:

$wgCategoryTreeCategoryPageOptions['mode'] = 'all';

--85.250.59.208 09:41, 24 February 2009 (UTC)

I also added the following which worked - sort of:

$wgCategoryTreeDefaultOptions['mode'] = 'all';

For some reason, though, this has no effect on the category tree that displays in the Sidebar.

What are MediaWiki.org's Settings? How to setup Category count and Page count in Tree View ie: (2 C, 10 P)?
What is the default setup in the MediaWiki.org LocalSettings.php for CategoryTree? I've tried about 12 different settings in my wiki and nothing behaves the same as this site, like on this MediaWiki.org page: Category:Top_level

I can't figure out how to configure two things:
 * 1) How to make category page display the statistics like: (2 C, 10 P) for 2 categories and 10 pages.
 * 2) My wiki also only shows [+] next to top level sub-categories, but not in secondary sub-categories.

Where is the documentation to show how to make these functions work with examples?

173.54.95.59 17:39, 10 March 2009 (UTC)


 * About 1. thing: You need to edit follwing article in your wiki: "MediaWiki:categorytree-member-num". You can do this if you put this article name into your search field and push "Go". If do the same on this wiki, or any other Wiki you can copy the setting from there into your own wiki. When including the category tree into a page you need to add the "showcount" option. Hope it helps. Elch71 07:23, 15 April 2009 (UTC)

Missing [+] signs
Got an odd error here, have recently upgraded to MW 1.14.0, I copied our existing virtual domain to a new one, did the upgrade - just being cautious now, and all works just fine. Rename the domain to the one we normally use - and whilst the Category tree loads just fine - I get no [+] signs at all - either in the sidebar or by calling the category tree for example in the Main_page. The list of categories is there, no errors are to be found the Apache log for missing images and so on. Anyone any ideas?

thanks Nibb 16:13, 25 March 2009 (UTC)

Just fixed this for our installation. Looks like maintainers try to enable display of the [+] via javascript only and changed the default to display: none. I went into CategoryTreeFunctions.php and reset the linkattr to display: inline and after clearing browser cache, voila it now works as expected.

665c665 <                      $linkattr['style'] = 'display: inline;'; // Unhidden by JS --- >                      $linkattr['style'] = 'display: none;'; // Unhidden by JS

Links not functioning
I'm flummoxed. I have two instances, a lab and a production, of MW 1.14.0. The production instance was configured by copying the lab over. All works well except the CategoryTree extension. In Production, the [+] link doesn't show up at all. When I try the fix from 72.166.192.10 17:31, 27 April 2009 (UTC) in, I get the plus signs but they don't do anything (and they show up on every category, with or without sub-categories).

The source for example pages shows the same html on each with the exception of style="display: inline;" on Production with the fix in place. Clicking on the plus does nothing.

I have compared LocalSettings.php and checked my .css and .js for all MediaWiki NS and there are no relevant differences. The only difference I see at all is the PHP and MySQL versions are slightly (5.2.0-8+etch13 lab PHP versus 5.2.0 Production and 5.0.32-Debian_7etch8-log lab MySQL versus 5.0.33-log Production) but the pages are rendering the same.

I'm guessing I'm missing a style or Ajax module somewhere but haven't found it.

Open up Sub-Subcategories on a Category Page
Hello,

I'm using Mediawiki 1.15.0 with the latest stable version of CategoryTree.

I've searched for a solution on google and in the history

of this talk but couldn't find an answer.

The problem is, that we want the ability to open also the subcategories of the subcategories shown on the category page. I managed to show the the pages in the subcategorie part. But I don't get the plus for opening the sub subcategories like on http://www.mediawiki.org/wiki/Category:Extensions and then on the Extension by integration target

I would be very pleased if someone could help me.

Greets,

Tom

--Hi Tom, I think this is the same problem as 1.10 "Can't get past first level of hierarchy" listed above. Source code for fixed CategoryTree.js (rev 51817)

Expand tree to current page
Would it be possible to modify the extension to show all levels up to the current page (if it is contained in the tree). We have an encyclopedia of a technical system divided into systems, subsystems, subsubsystems, etc. and we display the CategoryTree on each of the pages to allow users easy navigation and orientation. It would be great to have the tree expanded to the current page so that the users can get a quick impression about the location of the current article in the overall context. Maybe the current page could also be printed in bold.

BUG FOUND
The reason for this is that this extension produces incompletely closed  sections :-( Here is a HTML example that it produces for the browser:                         [+]           XYZ Note that two closing   elements are missing at the end. This can screw up your whole skin when using this extension in the sidebar.

And the missing tags also make it impossible to use the  tag in a bulleted list: The following example will totally screw up your generated page: *         *

Category Tree with memcached
We have a problem with memcached and CategoryTree. When we change the name of a page, the CategoryTree entry is not updated. Has anyone any experience with this constellation?

How to add MediaWiki:categorytree-member-num to an category without printing it?
Is there any way to add MediaWiki:categorytree-member-num to an category without printing the category in the tree? I tried  but the CategoryTree extension won't respect the noinclude! --Danwe 19:41, 17 February 2010 (UTC)
 * Still no way to add the page to a category. I think the extension really should check for noinclude tags to make this possible! --Danwe 14:44, 3 June 2010 (UTC)

sorry - diesmal auf deutsch
...was muß ich machen, um aus dem http-link "http://de.wikipedia.orgindex.php/?title=User:Ulli_Purwin" den entsprechenden funktionierenden link zu erhalten - oder besser noch: wäre es nicht ein leichtes für dich, diesen deadlink im script funktionsfähig "umzubiegen"? gruß, --Ulli Purwin 00:10, 18 February 2010 (UTC)

Why is [+] printed when there is no subcategories?
Great extension! But, why are the [+] visible even for categories without subcategories? It creates some confusion. Too bad it seemes no one is supporting this extension. :/ --P.Nilsson 14:04, 29 March 2010 (UTC)

This seems to be fixed in svn: Revision 66987 - Directory Listing Modified Fri May 28 02:15:44 2010 UTC (4 weeks, 5 days ago) by tstarling * (bug 23682) Don't allow people to expand subtree when it's known to be empty, this is inefficient. * Fixed a bug causing the "+" link to be shown even when the number of subcategories is zero, due to the DBMS returning a string instead of an integer, causing triple-equals comparison to fail.

But the svn changes don't work with 1.15.1 Maybe we could get a snapshot with those changes? Monkeyboydad 6/30/2010

Tree Menu does not work when running on Windows XP using IE or Firefox
After installing Firebug plugin on Firefox discovered that the path for baseDir on line 66 was not getting converted from a windows path to a Linux path. (path contained "\" instead of "/". Modified the code on line 66 from "$this->baseDir"  to "$this->baseUrl".

Problem on Colorado
We had to remove this from http://en.wikipedia.org/wiki/Colorado as it was causing excessive page loading times and timeouts. Is this a problem with this extension or a misuse of it on an inappropiate article? Exxolon 21:30, 9 August 2010 (UTC)
