Blank Page when enabled.
Q1a: I am running Mediawiki 1.8.1 and when I enable this extension My site goes blank. I turned off all other extensions to test if it was some type of incompatibility, but that didn't work either.


 * A1a: Check if after require_once("extensions/CategoryTree/CategoryTree.php") have a ; in localsettings.php like bellow:
 * require_once("extensions/CategoryTree/CategoryTree.php");
 * --kostas1972 [[Image:gre.gif | kostas1972]] 17:22, 15 October 2006 (UTC)

Q1b: Yes the ; is there. This is my configuration: MediaWiki: 1.8.1 PHP: 5.0.4 (apache2handler) MySQL: 4.1.20


 * A1b: so check if this line or any other line similar (for enabling extensions) is placed at the bottom of localsettings.php for example if extension "whoisonline" be placed on top or near top everything goes white ... when placed at bottom everything its ok.This happen because the extensions not loading at the right time and things mixed up, most common is to place them at bottom except one or two of them.
 * TRY change this orders .I cant find any other explanation...if not working :try redownload categorytree.
 * --kostas1972 [[Image:gre.gif | kostas1972]] 22:21, 16 October 2006 (UTC)

Q2a: OK, I got it working but I cannot collapse the tree. i get a javascript error: categoryTreeCollapseNode is not defined.


 * A2: the script working fine if you download from svn! i had notice that the tgz. file is full of errors try redownload the script delete all files and copy the newfiles in extensions/CategoryTree/ it should work with 1.8.2 and 1.8.1
 * i have the same php and apache versions on fedora core4 now working excellent ... my problems stooped... see bellow my other post for details about svn and packed tgz folder.

_______________ PROBLEM SOLVED : downloaded again the files from SVN this time and worked the link inside wediawiki-extensions/categorytree-extension provides this link :(download area with bundled version->notworking) provides a zip file with older(or broken) files ... someone must check and fix this. Download a working version from svn here: WORKING FILES FROM SVN repository I also made a Greek (el) translation for CategoryTree-extension available here  untill User Duesentrieb post it in svn and a (el) translation CategoryTree-external tool el be carefull this is the external tool not extension translation

 * What version is your wiki? 1.8.1 and 1.8.2 is supported and none bellow.
 * Have you carefully replace all files inside extensions/Categorytree/ with the new files?
 * Also make sure that you cleaned your browser's cache and reload page to see results and that all extension entries in localsettings.php placed at the bottom jast before ?>

All Pages options for Subcategory listing
Is there a way to enable the all pages option on category pages for subcategory children? I.E I have a number of documents seperated by month, and a category for each month. Each month category, in turn, is a subcategory of the year category, which is a subcategory of the main 'parent' directory.

When pressing the [+] beside the first child (the year) a reader will see the month, but when pressing the [+] next to month, the reader is shown "no subcategories" it would be benificial, at least in my case, to be able to display the contents of each month on the 'parent' category page. I know this can be done when using the  that is the format to display articles and subcategories in a categorytee....I suggested the redirection of category to a newpage as this will not display twice'''  the cats and sub cats in a category page..also can put the tag in any page to avoid redirections and guide users there.
 * The other extensions i mentioned is not exactly what you want but can enanche your articles listings...
 * Hope that this helped you...have a nice day.

My hack

 * 1) Locate where the CT_MODE_CATEGORIES is default parameter of a function, e.g. function efCategoryTreeAjaxWrapper( $category, $mode = CT_MODE_CATEGORIES ) {
 * 2) Replace by function efCategoryTreeAjaxWrapper( $category, $mode = CT_MODE_CATEGORIES ) {
 * 3) In efCategoryTreeParserHook function, replace else { $mode = CT_MODE_CATEGORIES; } by else { $mode = CT_MODE_PAGES/*CT_MODE_CATEGORIES*/; }

--Iubito 17:08, 19 November 2006 (UTC)


 * Not sure if anyone is still looking for a way to have the ALL or PAGES mode by default on the dynamically created "Subcategories" pages. The above hack only changed the default mode of the categorytree tag to PAGES, but it did not change anything in the "Subcategories" pages. I think I've found a way to do it though. I'm in the middle of testing this to make sure nothing else is broken. Please let me know if anyone is still interested in this. Thanks

Collapsed by default?
When using the tag method, is there a way to show the tree collapsed by default?


 * I agree. This would be a very good thing to have.  The Special Page has it about right.  It has the topmost level expanded, but all the rest aren't.  Anybody know how to best do this? --N0ctrnl 21:40, 14 November 2006 (UTC)

An onlyroot option has been added in 20385. @N0ctrnl: expanding one level is the default behavior. -- Duesentrieb ⇌ 11:43, 13 March 2007 (UTC)

Two wishes
I would like to have two features:
 * Remove the prefix "Category:" in tree. This is an easy one, isn't it?
 * Is it possible to remove the + before category with no subcategories/pages?

If these changes won't make it in your repository, can you tell me how to do it?

Thanks a lot, akw


 * Hi - the "Category:" prefix should be hidden if you specified that you want only categories. At least I vaguely recall writing it that way :) If the tree also shows normal pages, it would be confusing to omit the Category:-prefix.
 * It is not pssible to remove the + beforehand - only after the "subtree" has been loaded (that would be a bit tricky, but doable - look into CategoryTree.js). To know in advance if there are pages/subcategories in a category means an additional database query for each category shown (i.e. n calls instead of 1 call, for every time you load a category view) . That would be too slow.
 * Regards -- Duesentrieb 14:18, 24 October 2006 (UTC)


 * I don't think it is confusing to omit the category prefix everywhere, because every category has a [+] or [-] prefix. So it is always easy to distinguish a category from a normal page. JePe 10:49, 29 October 2006 (UTC)


 * I also wanted to remove the "Category:" namespace prefix from the "all" listing. This can be done by changing lines 289 to 291 (orginal lines shown below):

if ( $mode == CT_MODE_CATEGORIES ) $label = htmlspecialchars( $title->getText ); else $label = htmlspecialchars( $title->getPrefixedText );
 * 1) when showing only categories, omit namespace in label
 * By removing the conditional and always calling getText instead of getPrefixedText you can always get the text without the namespace prefix. So the short of it is you end up with the following code replacing the above code with the following code:

$label = htmlspecialchars( $title->getText );
 * 1) when showing only categories, omit namespace in label
 * 2) Roy's Hack: Always hide the category namespace label
 * --w:User:Imjustmatthew

As of Revision 17863, it is now possible to suppress the namespace prefix using the option $wgCategoryTreeOmitNamespace = true; See 8011. -- Duesentrieb 10:09, 23 November 2006 (UTC)

Now that a hack is no longer needed to remove the "Category:" namespace prefix, I am looking for a hack to "hack" a little more off the front end of my category names. In my application, each category is preceded by an uniformly formatted ID. Is it possible to replace the category text with a truncated copy of the text? If so, is it possible to evaluate the category text to determine if the leading characters meet a certain formatting criteria, and then make such a replacement? If so (going out on a limb here), how and where would I write the equivalent of the following SQL statement? SET category = Mid(category,17) WHERE category Like '(##) ## ## ## - *';

CategoryTree in the sidebar
I have made some css to load CategoryTree in the sidebar of Firefox. This is possible since every page has it's own class. The css strips everything from Special:CategoryTree except for the tree itself. It must be placed in User:XXX/monobook.css. For other languages than English the text "Special" must be changed to the right namespace-name.

body.page-Special_CategoryTree .firstHeading, body.page-Special_CategoryTree #jump-to-nav, body.page-Special_CategoryTree p, body.page-Special_CategoryTree form, body.page-Special_CategoryTree .CategoryTreeParents, body.page-Special_CategoryTree .portlet, body.page-Special_CategoryTree #footer, body.page-Special_CategoryTree #siteSub { display:none !important; } body.page-Special_CategoryTree { background:white; } body.page-Special_CategoryTree #content { margin:0; padding:0; border:none; background:white; } body.page-Special_CategoryTree .CategoryTreeItem { white-space:nowrap; }

Now you can load the following page and make a bookmark which loads it in the sidebar: http://en.wikipedia.org/wiki/Special:CategoryTree?target=Categories&mode=all JePe 20:34, 28 October 2006 (UTC)

CategoryTree nur mit Tag benutzen
Hi Düsentrieb

Wie ist es möglich, CategoryTree nur mit dem )

Ah, OK - youwant to tell it to automatically expand down to a specific node. That'S tricky - first of all, I would have to determine the full path from the "root" to the "current child" (which takes several DB queries). Then I would have to immediately expand down to that child (which again takes several DB queries). In your example, this is not such a big problem, because B is directly under A, and there are only three nodes total. But for a general solution, this could become extremely expensive if used incorrectly.

I don't see a way to do this cleanly, sorry. -- Duesentrieb 10:29, 23 November 2006 (UTC)


 * Yes, there has to be a recursive question for the parent. This procedure can generate some JavaScript code (in my example . For that I just see a little cost (just the number of parents). Perhaps I can gain some skill in PHP to do it by myself but do not bet on it ;)

CategoryTree.css and CategoryTree.js wrong MIME-Type
Hi,

We are using mediawiki 1.8.2 with Apache 2.0.54 and PHP 5.0.4, after installing CategoryTree and calling the Page, we got the message:

Error: The stylesheet http://wiki.MyDomain.net/extensions/CategoryTree/CategoryTree.css was not loaded because its MIME type, "text/html", is not "text/css".

and

Error: syntax error Source File: http://wiki.MyDomain.net/extensions/CategoryTree/CategoryTree.js Line: 1 Source Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

Apparently the $wgScriptPath seems not to work (in the LocalSettings.php is $wgScriptPath = ""; because the wiki is installed in the root). Any suggestion?


 * I'm pretty sure this problem is unrelated to the extension itself. The files are served directly by apache, not through mediawiki - so, if you see the wrong mime type, apache is giving the wrong mime type. Please try to enter the url directly into your browser and report what you see.


 * My guess is that apache is not serving the css and js files at all, but an (html) error page (probably a 404 or 500). I suspect this is due to rewrite rules you are using to have the wiki in the server's document root - you need exceptions to the rules for special directories, like /skins; For the CategoryTree extension to work, you need to make /extensions such an exception too. -- Duesentrieb 13:34, 22 November 2006 (UTC)


 * In short: You win! :) I put the 'extensions' into the RewriteRule an now it works as expected. Thank You!

default open depth
Would it be possible to specify how deeply the tree was initially open? It would be useful if the tree for a category coulb be made to list all of its subcategories and their subcategories; that is one level farther than is currently shown, as if every + was clicked. -Sanbeg 00:25, 5 December 2006 (UTC)

Problem with Firefox
I have a fresh installation MW 1.9.2 with categoryTree. It works fine with IE6.

Using Firefox (1.5x and 2.0.0.2) I can open the +, it displays load (laden) and then nothing.

Firfox error console reports: "Fehler: uncaught exception: Die Erlaubnis für den Aufruf der Methode XMLHttpRequest.open wurde verweigert" meaning "Error: uncaught exception: The permission to call the method XMLHttpRequest.open was not granted".

I do not use a short url. Any ideas? --GunterS 17:26, 26 February 2007 (UTC)


 * Some security policy seems to prevent the ajax call. No idea what it could be exactly. Do you have the same problem on other wikis, like wikipedia? Perhaps when using it with "ugly" URLs? -- Duesentrieb ⇌ 00:34, 27 February 2007 (UTC)


 * Seems to be a problem with the pc-firewall. Accessing the wiki from a pc with a different configuration there is no problem. --GunterS 08:59, 31 March 2007 (UTC)

Working on category pages but not when included
After installing the extension it works on the category pages and on the special page but when I try to manually put it on a page clicking the (+) doesn't do anything. I'm using the following code:

I also tried:

Please check your JS error log and report what it sais. Also look at the HTML source and see if CategoryTree.js is included properly. This might be a problem with the skin. -- Duesentrieb ⇌ 00:35, 27 February 2007 (UTC)

Good hint, looking at the HTML code of a page and comparing it with the special page I noticed the following entry missing:

  var categoryTreeCollapseMsg = "collapse"; var categoryTreeExpandMsg = "expand"; var categoryTreeLoadMsg = "load"; var categoryTreeLoadingMsg = "loading"; var categoryTreeNothingFoundMsg = "nothing found"; var categoryTreeNoSubcategoriesMsg = "no subcategories"; var categoryTreeNoPagesMsg = "no pages or subcategories";

Actually I use the default skin (Monobook) and also tried a couple of other skins - doesn't work on any of them. Any pointers where this JS code should be actually inserted?


 * It seems like efCategoryTreeParserOutput is not being called when the page is rendered. efCategoryTreeParserOutput implements the OutputPageParserOutput hook - maybe another extension is interfereing with that hook (for example by not returning true from its hook function). Try including the CategoryTree extension before any other extension. And check that OutputPage.php contains the line wfRunHooks( 'OutputPageParserOutput', array( &$this, $parserOutput ) ); - if not, your installation is somehow broken, or quite old. What version of MediaWiki are you using? The last possibility I see would be that something is messing with the ParserOutput object, and the mCategoryTreeTag flag is lost. -- Duesentrieb ⇌ 20:44, 27 February 2007 (UTC)
 * Thanks! It was another extension that messed with this hook. After I disabled it the category tree works perfectly fine...

Location of code that handles displaying the titles of the children?
Was wondering if anyone knew where in the categorytreefunctions.php the part where it handles the names of the children when you expand the tree? Reason is so I can edit the titles so they only show the last part of each title instead of the entire title, since the titles I use are seperated by colons and can get very long. It's not the $label area in renderNode section as it only handles the nodes being displayed first. Vince


 * It is $label in the renderNode function: ajax calls renderChildren, which calls renderNode. If you are not seeing the effects of your changes, there is probably a caching issue. Especially, look at $wgCategoryTreeHTTPCache and the calls to checkLastModified and loadFromMemcached in the ajax function. -- Duesentrieb ⇌ 11:08, 13 March 2007 (UTC)


 * Ah thank you for the quick response. You were right, it was just my browser cache showing what the old pages looked like in the tree. Vince

Compatible with 1.9.3?
Is this extension compatible with 1.9.3? Just did a fresh install, loaded CategoryTree (the only extension), Special:Version shows it to be loading, but the inline function returns "Category foo not found" (foo being a real, present category) and using the form on Special:CategoryTree just kicks me out the main page.

The js wasn't being loaded into the head of the template (monobook) initially, but even after I manually inserted the js into the head of the template, the plugin does nothing.


 * MediaWiki: 1.9.3
 * PHP: 5.2.1 (cgi-fcgi)
 * MySQL: 5.0.24a-standard-log
 * CategoryTree r20410

TIA, -S


 * Since the extension has been running in Wikipedia continuously since the days of 1.8alpha, I'm pretty confident it's compatible with all versions since. I have also used it with 1.9 myself. I don't know why you are having problems, sorry. -- Duesentrieb ⇌ 14:09, 17 March 2007 (UTC)


 * Thanks for the quick reply. Do you have any pointer on where I should start troubleshooting this? I'm afraid my knowledge is a bit AJAX deficient. Are there any debug or verbose options that can be set?


 * the best checklist is probably this talk page. Look at the problems other users where having, and how they resolved them. You can set Manual:$wgDebugLogFile, but i'm not sure if that would help you. Well it might give a clue why Special:CategoryTree dosn't work. You can also increase error verbosity:

$wgShowExceptionDetails = true; $wgShowSQLErrors = true; error_reporting(E_ALL); ini_set("display_errors", 1);

Zwei kleine Verbesserungsvorschläge für CategoryTree

1. In der README steht noch statt
 * http://meta.wikimedia.org/wiki/CategoryTree_extension
 * http://www.mediawiki.org/wiki/Extension:CategoryTree

2. was wichtiger ist, wenn nicht nur Kategorien, sondern auch Seiten im Baumansicht angezeigt werden, kommt es zu leere Tags im HTML-Code. Um das umzugehen, habe ich eine kleine Änderung in CategoryTreeFunctions.php vorgenommen:

Ab Zeile 334

$s .= wfOpenElement( 'span', array( 'class' => 'CategoryTreeBullet' ) ); if ( $ns == NS_CATEGORY ) { $s .= '['. wfElement( 'a', $linkattr, $txt ). '] '; } else { $s .= ' '; } $s .= wfCloseElement( 'span' ); wenn man die span-Tags ins if verschiebt, werden die Seiten wieder W3C passend if ( $ns == NS_CATEGORY ) { $s .= wfOpenElement( 'span', array( 'class' => 'CategoryTreeBullet' ) ); $s .= '['. wfElement( 'a', $linkattr, $txt ). '] ';   $s .= wfCloseElement( 'span' ); } else { $s .= ' '; }

 * Looking at the HTML from your wiki, it seems like your custom skin doesn't output the head scripts. When using a monobook/skintemplate based skin, you'd get those from $this->html('headscripts'), otherwise you'll somehow fetch them from $wgOut->getScript. Those scripts have to go into the html head section; they are used by many extensions and some built-in functions too. -- Duesentrieb ⇌ 22:56, 20 April 2007 (UTC)

Category Pages mode different
I have installed CategoryTree and made a few changes: * changing default mode to ALL in efCategoryTreeParserHook * omiting namespace

Does the CategoryPageSubclass.php file not use the default mode from CategoryTree.php?

129.186.146.159 19:31, 24 April 2007 (UTC)

That is your problem right there, and there's nothing MediaWiki can do about it (this is a request for a plain file - MediaWiki is not even called. Or shouldn't be); If there's nothing in the .htaccess file, check .htaccess files in "parent" directories, and also for aliases defined in httpd.conf. Also make sure apache is allowed to serve files directly from the extension directory - maybe that is the problem.
 * the "header fix" discussed was only for the custom skin he was using. It simply works with all the default skins. -- 217.234.232.131 09:43, 28 April 2007 (UTC)

Enhancement Suggestions
This is a realy great extension and I would like to make a couple of enhancement suggestions;

mode="hideEnptyCatagories" this would hide category subtrees that do not contain any pages.

colls="#" this would instruct the  categorytree tag to lay it's contents over a number of columns

- is this possilbe? in would like to have the tree split in 3 columns (because it's big) --89.212.65.33 12:27, 23 October 2007 (UTC)

hidenamespace="true" so categories would be displayed at "Coaches Australia" not "Category:Coaches Australia"

Lastly a catagoryreecontents tag. When a tree node is expanded the content of the node is then displayed in this tag - if present --JulianY 13:32, 2 May 2007 (UTC)

Possible to show all categories
I have a very small wiki, with a very flat category structure. Is it possible to modify your script so it shows all the categories (they have no common root). I could just put multiple trees, one for each category, but then I would have to update it every time there was a new category.


 * I would like to second this request. I also have a small site with relatively few categories and.  My maximum depth is 3 or 4. - Tnabtaf 00:03, 29 January 2008 (UTC)

Just make a root category, and hide it when showing the tree. -- Duesentrieb ⇌ 14:59, 29 January 2008 (UTC)

Darstellungsart / Viewing
de: Eine Differenzierte Darstellung wäre nett. Z.B. ein Parameter zu übergeben, welches die CategorieTrees nicht untereinander sondern nebeneinander darstellt. en: Diffenret kinds of viewing-possibilitys. For example showing the Trees besides and not among each other.
 * You can do that using CSS by wrapping the category tree in a div that has a special CSS calss assigned. But i'm not sure how well a side-by-side display will work when expanding nodes... -- Duesentrieb ⇌ 10:16, 14 May 2007 (UTC)
 * OK I added div-tags around the categorytree-tags with white-space: nowrap; but it doesn't work.
 * I also added the white-space: nowrap; entrys to all classes in the CategoryTree.css and CategoryTree.rtl.css but nothing happens.
 * display: inline; doesn't works too!

Categories Intersection
Hi. There's a way to use CatScan categories intersection with CategoryTree? It can be useful to get automatic lists for Portals. I use CategoryTree on w:it:Portale:Anime e manga, but adding a new intersection function on CategoryTree should make it more powerful and flexible. (and discourage composite categories creation) It's implementable?--Dzag 07:42, 19 May 2007 (UTC)

CategoryTree and Version 1.10.
I am using a own wiki (Mediawiki); Version 1.10. I tried to install categoryTree: I copied the categoryTree-Folder into extensions and added the two lines


 * $wgUseAjax = true;
 * require_once( "/CategoryTree.php" );

to the localsettings; it tried it also with the full path

require_once( "/var/www/w-handwerk/extensions/CategoryTree/CategoryTree.php" );

but I get always the error-message:

Parse error: syntax error, unexpected T_VARIABLE in /var/www/w-handwerk/LocalSettings.php on line 125

line 125 is the $wgUseAjax

what is wrong?

Needs a mode restricting to the current page's namespace
the Pages mode leaves out articles in the Images namespace. There should also be a mode which limits articles to the same name namespace as article you're in, or a nominated namespace (as opposed to all namespaces except Images).

I have a silly question.
I've installed a personal wiki on my system at home, version 1.9.3. I've installed CategoryTree and it works fine. I've set the variables -

$wgCategoryTreeOmitNamespace = true; $wgCategoryTreeDynamicTag = true; $wgCategoryTreeDefaultMode = CT_MODE_PAGES; $wgCategoryTreeCategoryPageMode = CT_MODE_PAGES;

In the example shown in the box on the "Extension:CategoryTree" page, the "manual" category indents each child when you click on the minus sign. My system here at home does not indent the child pages that I create.

Q- Is there a variable that I need to set somewhere that will indent each child.

I suspect this is about me changing my style sheets or adding another extension to my system rather than what CategoryTree is doing.

--Allyn 17:25, 4 June 2007 (UTC)


 * I have encounted the same problem. The cause of the problem was that I have moved the extensions folder to a different location. I created a symbolic link from the original location to the new one, and then indentation worked. --Tillmo 13:05, 13 November 2007 (UTC)

Another question with 1.10.0
I've followed the instructions per the README file. When I try and use it with the tags, or use the Special to search for categories, it always says that the category cannot be found. I'm not getting any errors or anything. Any suggestions?

--Pndfam05 19:40, 29 July 2007 (UTC) It sounds like the problem I encountered with 1.10.1. CategoryTree will only locate categories when the category page has been created. When you open Special Pages:Categories are all of you category names red? If so then the category page has yet to be created. Try using one of the blue category names between the CategoryTree tags. If you do not have any blue category names then click on a red one, insert some text on the page, save it and then try CategoryTree again.

Older Versions
Is there a version of this extension that will run on mediawiki 1.65? My ISP will NOT upgrade the PHP software so I can't upgrade :-(

- I have the same problem.. how do you locate older revisions?

CategoryTree will not work with anything < MediaWiki 1.8, sorry. -- Duesentrieb ⇌ 21:28, 18 November 2007 (UTC)

Articles in more than one Category
Could you include a function, that makes filtering possible?

For example:
 * Article A is in Category 1
 * Article B is in Category 2
 * Article C is in Category 1 and Category 2

now I type the following code into the wiki the result is Article A and Article C, because they are both in Category 1

I Would prefer the following function: the result is Article C because Article A would be filtered out.


 * I don't think I'll open that can of worms. From writing meta:User:Duesentrieb/CatScan, I know that there are lots of filters that would be nice to have, and that it's quite hard to write efficient database queries for them - especially since people want to combine them.
 * As to your example: the syntax seems odd. To me, "|" would indicate the union, not the intersection, of the two categories. "&" could be used for intersection, but that's a valid title character, wich makes it tricky.
 * Maybe I'll add a way to hook into CategoryTree, to allow people to write their own filters, with a minimum of PHP codeing. But even that could proove tricky... -- Duesentrieb ⇌ 13:46, 25 August 2007 (UTC)

Subcategory/article count
Is it possible to get a subcategory/article count (depending on the mode)? Otherwise I'm stuck with trying to do it with Dynamic Page List... -Eep² 03:33, 28 July 2007 (UTC)


 * Couting the elements in a category is as expensive as listing them. When showing 100 categories, it would amount to 100 additional database queries (using subqueries doesn't make it much better). This type of overhead is not acceptable. -Duesentrieb


 * To you, perhaps, but on a smaller wiki it's negligible. Leave it up the wiki owner to decide. -Eep


 * Hello? I've done it with DPL but it doesn't have the javascript branching that CategoryTree does... More suggestions for options:


 * Use images for the "[+]"/"[-]" text controls (easier to click since the brackets don't work)


 * Images don't scale and should be avoided as UI elements. Making the brackats clickable would be possible, but making them look link-ish would be ugly, IMHO. -Duesentrieb


 * Leave that up to the wiki owner as to which image should be used and how the text link should look like (like use "[$1]" in a system message and allow the $1 to be configurable too, as text or an image), but simple adding an image scale proportion adjustment parameter would be sufficient if it concerns you that much. However, you don't see such issues arise in favicons (16x16) and even default Windows desktop icon sizes (which range from 16x16 to 48x48 but 32x32 is the most common). -Eep


 * Display bullets for pages


 * Maybe. Yea, why not. When I have time. -Duesentrieb


 * Remember opened/closed branches (via cookie?)


 * this would case some massive overhead when flipping through your browser history. It would also be a mess to code, basically spamming you with dozents of cookies, or cluttering the session data on the server. I don't think it's wort it. -Duesentrieb


 * Again, leave that up to the wiki owner to decide. Why limit functionality based on what you think will cause "spamming" and server session data cluttering? -Eep


 * -Eep² 05:13, 1 August 2007 (UTC)


 * I second these - I think these are great suggestions (though of course I'm not a coder, so that's just my opinion). Also, I hope that in time, cats without subcats will automatically display a "[-]" instead of a "[+]" even before being clicked. --Chriswaterguy 09:15, 11 August 2007 (UTC)


 * $wgCategoryTreeOmitNamespace</tt> "doesn't show the namespace name for pages and categories. Default is false, namespaces are shown unless showing categories only." But I would like an option to show all namespaces except "category:" for all modes. Specifically, I want "template:" visible with CT_MODE_ALL</tt> and CT_MODE_PAGES</tt> and I would like to force more than one level of branching to automatically open. I can't get this to work at all even with this: $wgCategoryTreeMaxDepth = array(CT_MODE_PAGES => 3, CT_MODE_ALL => 3, CT_MODE_CATEGORIES => 3);</tt>. —Eep² 07:53, 25 August 2007 (UTC)


 * This would be inconsistent, since Pages would look the same as Categories (ok, except for the [+] up front). I don't like inconsistencies like that, and too many modes make the code overly complex (see en:Feeping_creaturism); -Duesentrieb


 * It's not, really. This is for when pages are displayed under categories, because there is only italics to represent pages/articles, categories are distinguished. However, if there are templates and other namespaces, same-named pages in different namespaces look like duplicates. I'd rather have the namespace in front for pages/articles under subcategories in these instances. -Eep


 * Opening more level initially: I don't really like this feature, it was added by someone else. However, it seems to work ok when I tested it, and your configuration looks fine (assuming you are setting the depth attribute in the &lt;categorytree> tag). -Duesentrieb


 * No, I'm not using a tag but instead the default category page. I want at least the first level open for each subcategory on category pages by default without having to use a tag. -Eep

categorytree inside of a template

CategoryTree in SideBar Problem
Hi guys hope you can help. Ive got the CategoryTree working in the SideBar but there is a problem. It works fine when expanding out the tree on the Main Page. I can click on a child on the Main page and it goes to the right location. However, when Im at the new location other than the Main Page, I get a similar problem to what has already been discussed under "Clicking the [+] has no effect / gives JavaScript error".

The thing is: 1) On the new page, I can click on the root of the category tree, and it takes me to the right location. 2) On the new page, I can click on the root and goes to that root fine, but I cannot expand that roots children out. I CAN expand the CategoryTree out successfully on the Main Page only, but no other page.

The error code Im getting on pages other than the Main Page when using the CategoryTree from the sidebar is: Line 671 Char33 Error:Object Expected Code:0 URL: <the url of the new page Im currently on> I have checked all is correct with the notes on "Clicking the [+] has no effect / gives JavaScript error".

SUMMARY:

On the Main Page: I can expand the category tree successfully, and click on children successfully. On Pages other than the Main: [+]Category (If I click this, it goes to this page) [+]Category (If I click this, it goes to this page) [+]Category (If I click this, it goes to this page) eg. [+]VBScript (If I click on VBSScript, it goes to http://localhost/mediawiki/index.php/Category:VBScript When I hover over the [+] next to VBScript, the path is looking at http://localhost/mediawiki/index.php/Category:VBScript# Questions. This error Im getting. What file is the error coming from, and how to correct? Thank you.
 * 1) I can click on the root of each category and go to that page:
 * 1) If I try and click on the [+] sign next to the Category Name, eg. the [+] next to VBScript, I get the error message.

CategoryTree in SideBar Problem - "Solution" Found

Adding a Category Tree [+] Tab next to Edit, History, Protect, Delete
Hi guys, Just wondering how you would go about adding: 1) An extra tab next to Edit, History, Protect, Delete, for every page. 2) A Category Tree [+] tab next to Edit, History, Protect, Delete, for every page. Thank you.
 * What exactly would that tag do? Take you to Special:CategoryTree? It can't expand in-place, that would put the tree inside the tab... or would you want something like a "popup"?
 * Also, what category should that tab refer to? Or do you only want it on category pages?
 * Furthermore, "+" is a bad choice: On talk pages, there already is a tab labeled "+", which creates a new section.
 * Can you clarify? -- Duesentrieb ⇌ 09:31, 13 September 2007 (UTC)

On a brand new installation of mediawiki 1.11.0 I've created two categories using http://www.mediawiki.org/wiki/Extension:TagAsCategory and they both appear in Special:Categories, however neither can be found on Special:CategoryTree. I have added pages to both categories yet Special:CategoryTree reports "Category ... not found".

 * Please give a link to a page that shows this problem, or at least explain exactly what the categories are called, and what syntax and parameters you used with CategoryTree -- Duesentrieb ⇌ 08:38, 18 September 2007 (UTC)

Ok, sorry for not explaining in more detail. Unfortunately I cannot provide an external link to the wiki. I have two categories; "Testcat" and "Othercat". Testcat has two pages, "Testpage" and "Testpage2". Othercat has "Testpage3" and "Testpage4". On the Special:Categories page both Categories are listed successfully and they both have 2 members each. However when I search for Testcat or Othercat on the Special:CategoryTree page it returns "Category Testcat not found". Also, when I insert into the page markup the page displays "Category Testcat not found". I have Javascript enabled and I created the two categories using http://www.mediawiki.org/wiki/Extension:TagAsCategory. I downloaded CategoryTree from svn on Tuesday 18th Sept. Thanks in advance.


 * Do the category pages exist? i.e. are links to the category blue? if they are red, the category has "content", but no "page", and categorytree will list them as non-existant.-- Duesentrieb ⇌ 13:48, 24 September 2007 (UTC)

 * I solved the problem through my ISP. I checked an option in my ISPs control panel to enable it to run scripts, this took a day or so for them to move it to a server that ran scripts.

Reverse Proxy Engineered Wiki
Same problem occures while trying to reverse proxy a wiki. This technique is commonly used by corporate intranet sites and wiki's, e.g. External address: https://company.com/wiki, Internal address: http://co.local/wiki.

Solution: (works on intranet as well as 'outside'): Change the wiki/skins/common/ajax.js as followed:

Reason: wgServer is your local server Address (i.e. 10.0.0.x).

Now your employee loggs on from an external source and tries to access https://company.com/wiki, but gets the imfamous "Error: uncaught exception: The permission to call the method XMLHttpRequest.open was not granted" error message (in FF at least he does, otherwise he gets an Access Denied Error on       line ~109, char 3).

Keep in mind that wgServer points to an internal IP-address, and is invalid for an external user.

Hope this can be fixed in future releases of MediaWiki, absolute URLs must be avoided, due to portability, migration and rare cases of reverse proxy engineered intranet-sites.

Omit Namespace
Is there a way to omit the namespace without using $wgCategoryTreeOmitNamespace = true? I'm on Wikipedia and wish to use with this enabled (or rather disabled) for all viewers without having to instal the CategoryTree extension. Is there a way to do this similar to how mode is chosen (<category tree mode="all" omit namespace="on">)?


 * I'm very reluctant to add more options, for technical reasons: adding an option means adding parameters to multiple php functions, and mutliple places in the JavaScript code, and also considering all options when creating cache keys - all of which needs to be kept consistent. this makes the code more prone to oversights and errors, and it also makes caching less effective.
 * This is a general problem with ajax-based extensions. If I come up with a nice and clean mechanism to handle options for ajax calls, I'll be happy to use it for the category tree too. -- Duesentrieb ⇌ 08:52, 22 September 2007 (UTC)


 * Sounds like the code isn't optimized very well then... You may want to consider a rewrite so adding things is easier. I'd like to be able to have the non-category namespaces show, for example, but as CategoryTree currently is coded, it's all namespaces or nothing. :/ —Eek 21:07, 22 September 2007 (UTC)


 * optimization is about performance, not about flexibility or modularity of the code. But yes, it sucks that it's hard to add options. Feel free to rewrite it. I have it on my todo list, somewhere around position 42311. -- Duesentrieb ⇌ 21:50, 26 September 2007 (UTC)
