How to use it in VisualeditorEdit

I want to use this extension in the visualeditor, but it does not work. Does anyone know the setting method?


Selectbox-StyleEdit

Is it possible to make the category listing with Select category look like Categorytree, so if you have 500 categories, you don't have to browse trough all but push the + symbol in front of the main category.

--Aroekene 22:00, 5 June 2008 (UTC)

  • I have the same request! THis would be great!


After changing the css-definition of ul#SelectCategoryList (and not just the css-id #SelectCategoryList) to the following:

ul#SelectCategoryList 
{
list-style-image: none;
list-style-type: none;
background-color:#EEEEEE;
height: 150px;
width: 50%;
overflow: scroll 
}

the SelectCategoryList is a bit less space-hogging (and I think "my" category-list isn't that long...), but I really think another way of displaying the choosable categories is very much needed!
A solution alike to the CategoryTree would be great, but I also think having more than just one column in the SelectCategoryList might be another way to increase the usability.

Sadly, my programming-/css-knowledge is way to small to conquer the task. :-(

Hopefully, somebody reading this has the know-how.

Call-time pass-by-referenceEdit

Warning: Call-time pass-by-reference has been deprecated in 
...\mediawiki\extensions\SelectCategory\SelectCategoryFunctions.php on line 21
Warning: Call-time pass-by-reference has been deprecated in 
...\mediawiki\extensions\SelectCategory\SelectCategoryFunctions.php on line 103

I tried

  • allow_call_time_pass_reference = On in php.ini

and

  • adding "?>" at the end of the php files

but this did not fix anything

Tool Version
MediaWiki 1.13.3
PHP 5.2.8 (apache2handler)
MySQL 5.1.30-community

Please suggest a fix, thank you.

Different version - same errorEdit

After upgrading to MediaWiki 1.15.1 and the concurrent extension-snapshot I get the same error-messages:

Deprecated: Call-time pass-by-reference has been deprecated in /opt/lampp/htdocs/_fhbwiki/extensions/SelectCategory/SelectCategoryFunctions.php on line 21
Deprecated: Call-time pass-by-reference has been deprecated in /opt/lampp/htdocs/_fhbwiki/extensions/SelectCategory/SelectCategoryFunctions.php on line 103

I've tried putting:

error_reporting(0);

at the beginning of SelectCategoryFunctions.php but that makes no difference whatsoeverer.

As far as I can say, the extension works, but instead of displaying the usual selection-window a long list with control-boxes appears.

Everything works ok with:
MediaWiki 1.14.0
PHP 5.2.9 (apache2handler)
MySQL 5.1.33

But the error occurs with:
MediaWiki 1.15.1
PHP 5.3.0 (apache2handler)
MySQL 5.1.37

I also need help with fixing this.

$wgSelectCategoryEnableSubpages ignoredEdit

I testet the extension under 1.10. But the disabling selection by subpages will be ignored if $wgSelectCategoryEnableSubpages = false; -- User:OZZ 18.052007

Seems to be just a typo in the code, just replace in the functions php $wgSelectCategoryEnableSubpage with the correct $wgSelectCategoryEnableSubpages -- Venia 15:52, 10 December 2008 (UTC)

Has someone tried it on 1.6.8?Edit

Is there a technical reason that it does not work there?

Yes, there is. We introduced new member variables which will be available in release 1.8.3. Otherwise it can't work. --80686 14:04, 29 November 2006 (UTC)

not removing categoriesEdit

I think it's better if categories aren't removed from the edit box. I've sumitted a batch at bugzilla:8359. It might also be nice if the categories had checkboxes next to them, but that seems a little more complicated; this simple solution makes the extension seem more useful for me. -Steve Sanbeg 20:06, 22 December 2006 (UTC)

working on it. It's not that easy, but it will work. On the other hand will this handling lack of the comfort the extension should provide. --Manuel Schneider(bla) (+/-) 21:57, 3 January 2007 (UTC)
Cool. For the uses I see for it now, it isn't necessary to completely hide the categories; and this option would prevent someone from clicking a category on the list and accidently removing all of the existing categories. -Steve Sanbeg 17:08, 5 January 2007 (UTC)
I upgraded my wiki, and was starting to test in production when I discovered the cycle bug. so I guess that will have to wait. But I wanted to mention (in case you didn't notice) that my patch also fixes one other, minor bug; there was a missing preg_quote on the custom namespace, which could break if someone names their namespaces oddly. -Steve Sanbeg 19:24, 19 January 2007 (UTC)
I just added a javascript file to my install of this extension that simulates the behavior of holding Ctrl when selecting categories in the multi-select box. This way selecting a new category does not unselect any existing selected categories. -Jimmysessions
I added checkboxes and submitted a patch. Leon Weber was kind enough to add my patch to the next revision. --Emceelam 19:12, 25 July 2008 (UTC)

Fatal ErrorEdit

I'm getting a fatal error when trying to create or edit a page using this extension. I'm Using Mediawiki 1.8.2.

Fatal error: Call to undefined method Title::isSubpage() in /mounted-storage/home24b/sub001/sc112516-ZBLG/wiki/extensions/SelectCategory/SelectCategoryFunctions.php on line 25

SelectCategory doesn't work with MediaWiki 1.8.2. Go read the contents in the red box on SelectCategory. --Manuel Schneider(bla) (+/-) 19:25, 3 January 2007 (UTC)

ConsiderationsEdit

I was about to post about that which was mentioned above - this definately shouldn't remove the categories from the edit box itself. The reason *I* was going to bring forward was different - lots of templates place pages they are transcluded onto into categories, and most such templates have their categories in <includeonly> tags. There are also other such cases where the placement within a page of the category tag matters - so I would appreciate it if the previous poster's suggestion and/or patch are applied, for very good reasons. Secondly, again, sometimes categories are assigned to a page by way of templates transcluded onto it, or other things - so it may be a good idea to list below the box the categories that the page is in that aren't in the box. Maybe also remove them from the box, as they shouldn't be unselected (or selected, for that matter) there.

One other thing I was considering, is that it might be a good idea to make this a seperate page - as in, perhaps a 'categorization' caction tab, or a 'categorize' button under the edit form along with save, preview, and changes - that way, a user could go to a SEPERATE page to work on the categories using this cool method, then return and see the changes - we don't really want two ways to do the same thing on one page, and having the AJAXified box AND the normal text box is exactly that - two ways to do the same thing. Did that make sense? I mean like the user clicks a 'categorize' button under the edit summary box, they get taken to perhaps a special page, or just another page action, where there is nothing but the selectcategories box, and a list of categories the page is in - then they can change them, and click 'save categories' to return. Peerless 03:11, 6 January 2007 (UTC)

I agree with that. Although I don't think this extension could ever work well in template space, my patch would prevent it from being a complete disaster. A categorization tab could be cool. -Steve Sanbeg 19:18, 19 January 2007 (UTC)

EnhancementEdit

would a category cloud (like a delicious tag cloud) be possible. It strikes me that categories are equivalent to tag) and having the most popular ones most highlighted may be helpful.. (not so for esoteric subjects) but on the whole helpful. Perhaps mediawiki would be enhanced by tags as well as categories (sort of meta categories)

There are at least two extensions that already offer tag or category clouds, ie Extension:YetAnotherTagCloud and Extension:CategoryCloud. I don't think either of them offer them on the edit page though. pfctdayelise 04:19, 19 April 2007 (UTC)

It would also be helpful to remove "parent" categories, or the current category from the select list. This would prevent users from creating circular references.

Bug When Category Name Has Space In ItEdit

I've noticed a bug in the current version from SVN (haven't checked the latest stable). If an article is part of a Category which has a space in it's name (example: Category:Test Servers), it doesn't show as selected in the list when editing the page (although the Category does show up in the list). Haven't tested what happens when I hit save but I assume it would be removed from the Category. --128.233.131.139 21:46, 23 March 2007 (UTC)

I hit save - it removes any categories not selected, which makes this extension too dangerous to use on an existing wiki page for users who aren't aware of the bug. It seems that an underscore is an acceptable character instead of a space. --24.97.28.170 03:54, 22 June 2007 (UTC)

See Extension_talk:SelectCategory#Patch_to_support_categories_with_spaces below.
This problem is fixed in SVN trunk. --Leon 17:32, 5 August 2008 (UTC)

New install - No category listEdit

MW 1.9.3, apache, WinXP fairly new install

I have just downloaded the tarball and installed the extension. I have added the require_once. I have tried leaving the defaults and do not get anything when going into edit.

We have refreshed the browser and have tried a different browser and workstation. Still nothing.

Not sure what we might have missed. Ideas?--Dtsig 21:50, 30 April 2007 (UTC)

You have already created some categories... right? :) --pfctdayelise 11:29, 1 May 2007 (UTC)
Sorry should have said that. Yes. We also use CategoryTree and it is working. Is there anything else to do with the install other than putting the folder in extensions, add the require_once line to LocalSettings? Just to be sure that it was firing I did put an echo at the beginning of SelectCategory.php and it did display (wasn't actually firing for the event but just the require fired it). Any debug ideas? problem with php .. it is like old languages where you had to debug to a line printer <g>--Dtsig 12:23, 1 May 2007 (UTC)
Still trying to work this out. What would be the best way to debug this. To get output of anything so we can be sure that the hook is firing? Thanks --Dtsig 13:51, 11 May 2007 (UTC)


Further, I placed the following code at the start of each function (with correct function name) so i could see what the last function that was it was thinking this might help you know where it seems to be stopping. The file showed 'fnSelectCategoryOutputHook'. Not sure if this helps but this appears to be the last thing that happens.
$rtn = file_put_contents ( 'phptest.log', 'got here - fnSelectCategoryOutputHook');
Ideas?? --Dtsig 15:11, 11 May 2007 (UTC)
And the answer is .. Conflict. We are also using DiscussionThread extension. I am sending a note to its developer and hope that you and/or he can figure out where the conflict comes from. Please let me know as both are great extensions for out users. --Dtsig 15:34, 11 May 2007 (UTC)

Conflict Resolution?? --Dtsig 18:08, 11 May 2007 (UTC)Edit

In working with the author of ThreadDiscussion we found that he had left 2 wfDebug functions in his code. Although this SHOULD NOT effect SelectCategory it appears that it does. This might be something you want to look into .. thanks

SortEdit

The category select box does not seem to sort ? is this a bug or will this be done in the future?

Mediawiki 1.9.2

Many thanks --Markw21 11:56, 8 May 2007 (UTC)

Preview removes all categories --Dtsig 18:09, 11 May 2007 (UTC)Edit

It appears that using PREVIEW will remove the categories. My guess is that since you strip out the categories upon entering the editor, they are forgotten and lost during preview. This seems to be a problem.

Being Reviewed? --Dtsig 18:53, 17 May 2007 (UTC)Edit

Has this been looked into? Can anyone else verify this?? thanks

Noted in Bugs on first page --Dtsig 19:19, 17 May 2007 (UTC)Edit

Check out .. See bugzilla:9849 for a patch.

MW 1.10 and preview error --Dtsig 16:18, 20 June 2007 (UTC)Edit

If you enter the following wrapped in pre tags (or code or geshi highlighting)

this starts on col 1
  this starts on col 3
    this starts on col 5

Then in edit/preview mode the spaces are all removed. If we comment out

require_once( 'extensions/SelectCategory/SelectCategory.php' );

then all works well

I don't really like the comma I added to separate the categories in the preg_replace, but it works.

MW 1.10.1 / WinXP/IIS - Category not pre-selectingEdit

Hi, i just dl'ed and installed this and followed the directions (which were very clear by the way-thanks) to install the extension. I have added the require_once.

Everything works except that if a page already has caterories in it then they are not pre-selected in the multi-select list.

Is this on purpose? Cheers, Wayne

I submitted a patch to Leon Weber that fixes this bug. Not quite the same solution, but it fixes the bug nevertheless. My patch has been included in the current release. --Emceelam 05:42, 1 August 2008 (UTC)

Existing categories bugEdit

The function fnSelectCategoryGetPageCategories() needs to do a number of things to work correctly and efficiently:

  • Make a copy of the page text in another variable
  • Remove all lines not matching the category pattern
  • Split each line at [[ and ]]
  • Remove all lines not matching the category pattern
  • Convert spaces to '_'
For this last item, see Extension_talk:SelectCategory#Patch_to_support_categories_with_spaces.

This will solve the following two problems:

  • Multiple categories on one line show up as only the last category link
  • Categories with spaces don't get selected

Note that the categories lists generated by the extension itself always work.

Critical Crash on EditEdit

Hi there, this has been a real pain to track down, but finally found that the SelectCategoryList was causing the problem.

Symptoms - cannot edit any wiki page.

Having reverted Apache versions and many other things, get php error output, can now see following errors...

Fix for trimming white spaceEdit

If you trim the white space from the beginning and end of a line, you wind up killing indents (see the below diff? Edit the page and save with your extension and it becomes a big blob of text). You simply inappropriately used trim.

SelectCategoryTagCloud is stripping Leading spaces from text linesEdit

Hey all, first off I just wanted to say I love this extension. I tend to forget the spelling of my categories and always get them messed up this is a huge help. That being said I discovered a problem with the extension. It strips out the leading text from your wiki page. This is only a problem if you are trying to use the leading spaces to create sections on the page. I tracked the problem back to "CategorySuggestFunctions.php" file. In here you are using the "trim" function which strips the blanks from BOTH the front and end of the lines. I changed all 4 "trim" commands to "rtrim" and the extension is now working fantastically. Anyway I wanted to pass this info on so it can be included into the new versions.

Patch to support categories with spacesEdit

The following change seems to fix the problem where categories with spaces are silently ignored. Find the line preceded by "# Get the category link from the original text and store it in our list:" and change it to:

$m_catLinks[ preg_replace( '# #', '_', preg_replace( "/.*{$m_pattern}/i", $m_replace, $m_textLine ) ) ] = true;

Select category/CategorytreeEdit

Is it possible to make the category listing with Select category look like Categorytree, so if you have 500 categories, you don't have to browse trough all but push the + symbol in front of the main category. --Aroekene 22:00, 5 June 2008 (UTC)

That would require two things:

  • a code change: currently sub-categories are indented by &nbsp;. They should be in a nested <ul> instead.
  • some javascript to expand/collapse the tree when clicking the "+" symbol

--Cboltz 23:03, 16 June 2010 (UTC)

For the records: Version 0.8 contains exactly this feature :-) (jQuery treeview) --Cboltz 20:12, 28 February 2011 (UTC)

PHP has encountered a Stack overflowEdit

This is the message I get when I try to edit pages now. SelectCategory worked fine for some hours of work, but now I get this message. Is there a way that I can debug the problem?

What version of the SelectCategory extension are you using? Try to use the current code from SVN trunk. --Leon 17:24, 5 August 2008 (UTC)

Did you consider users mistake?Edit

Hi, If a user create a category and then directly or indirectly make this category as its subcategory for example:

book --somebooks -- -- book

your extension goes to an infinte loop, and mediawiki breaks. please let me know if you solve this type of problems.

See User:Cm#Updates_to_SelectCategory

How to have the category list to scroll ?Edit

Hi, first of all excellent extension very pragmatic. I only have one problem, I'm not a software or developer or what not. My question is how to have the category list at the bottom to scroll?


What I didEdit

1. Get access/rights to MediaWiki:Common.css
you might need to get rights to edit common.css
you might need to create it
2. Insert the following text:
ul#SelectCategoryList 
{
height: 200px;
width: 400px;
overflow: auto;
}
3. Edit the width and height properties to be bigger or smaller according to preference.
you may need to delete your browser's cache in order to see changes you make to common.css

No SelectCategory-List when editing only parts of a pageEdit

For the casual user it is quite comfortable to choose from the list. But I also have the extension "RequireCategory" which forces the user to assign at least one category when trying to save an uncategorized page. Otherwise the page cannot be saved. If one edits the whole site, SelectCategory is there to help my casual user. But if one edits only a part of an uncategorized page there is no SelectCategory-List and my casual user who does not know how to assign a category manually does not know what to do.

In short: can I show the SelectCategory-List also when editing only a part of a page?

Add Category box and disabling infinite category loopsEdit

If the user is editing a category page, the selectboxes for that category and all undercategories are greyed out. Code at User:Cm#Updates_to_SelectCategory --Cm 15:40, 29 October 2009 (UTC)

Compatibility Problems with SemanticMediaWiki QueriesEdit

With the help of Semantic MediaWiki one can make Inline Queries, e.g. to create a list of all pages in a category which have the attribute xy > 2000 assigned. The Extension SelectCategory removes every [[Category:xy]] on every page, no matter if it is between "nowiki"- or "#ask"-tags. So if I want to make such a semantic #ask-Query which refers to a category, the query is broken by SelectCategory because it deletes the [[Category:xy]] and assigns the page to this category. Could this be changed please? --Laquestianne 09:20, 25 February 2010 (UTC)

I fixed it with a small change. See SelectCategory: Fixed by users --Laquestianne 12:11, 10 March 2010 (UTC)

Long Category ListEdit

Hello, we are thinking about integrating SelectCategory into our Wiki (www.pflegewiki.de). We experience the "problem" that many articles are being created/edited without applying a category to it. So I searched and found this one here. The PflegeWiki has got a lot of categories (something about 300) and this will be a very long list. Is there a way of compacting it in some way? Maybe a dropDownList or similar? Or shorten the list of cat's by not listing unused cats or just define cats to a certain namespace? I know a hell lot of questions but has anyone any suggestions to this? Thanks, --Bruder Lars 06:55, 7 April 2010 (UTC)

How to avoid removing categories shown in edit box?Edit

Hi, The extension seems to remove the category shown in edit box. How could i disable them to do it?

I tried this: Remove line 41 from SelectCategoryfunctions.php "$m_pageCats = fnSelectCategoryGetPageCategories( $m_pageObj );"

Then, categories now appears in edit box.

However, there is one drawback that the predefined list categories will not show which of them have been selected. Do anyone know how to solve it? Thanks a lot! --Dullmau 16:04, 8 June 2010 (UTC)


List predefined category and check those who are checkedEdit

set an array for predefined category:
$cat_predefined= "Asia,America,Europe,Africa,Middle_East"; $catlist_predefined = explode(",", $cat_predefined);

If a category exists in a page, <input> checkbox will be checked.
for ($i = 0; $i < count($catlist_predefined); $i++) {
$checked = ;

if($category == $catlist_predefined[$i]))
$checked = 'checked';
}

I've tested it, but it sometimes work only. The problem may lie in if($category == $catlist_predefined[$i])) . $category may not be the variable for storing categories that exist in a page. --Dullmau 09:41, 10 June 2010 (UTC)

You need to replace every occurrence of &$ with $ in extensions/SelectCategory/SelectCategoryFunctions.php in order to solve the error listed above. I'm not really sure, if this action may alter the behaviour of the code, since I do not have the necessary PHP-knowledge. Perhaps someone who's PHP-fluent can have a look, please?

I'm running MW 1.16.0, Vector skin, and when I use the stable release, I have the following problems:

  • above the categories the text <selectcategory-title> is shown instead of the real title
  • the [+] signs are not interactive. They are text-only and nothing happens when you click them

I reverted to an older revision still having the listbox, but that one works --83.65.127.178 10:51, 27 January 2011 (UTC)

MW 1.16.0 and vector skin, cat. tree is not working IE8Edit

Great extension and almost perfect!
The [+] sign is not working and the subcategries are al listed. (collapsing and expanding is not working) clicking on the plus sign has some action by inserting a small blank line but thats all that happens.
Trying to find the problem I was performing some echo's in the php scripts and when I perform a php echo("x"); on line 80 in SelectCategoryFunctions.php (version 0.8, just before building the list) it seems to work. Sadly the editor box is affected also by the echo and is shrinked to approx. one third of the page so i cannot use it as work around.....
Any help about this is appreciated because this extension is a great help when editting pages on our Wiki!

Select Category on UploadEdit

Am I right that this extension should also add categories to files while uploading? The category tree is available on Special:Upload but after uploading the files have no categories.

Thanks for Support --Filburt 11:04, 13 April 2011 (UTC)

That's probably https://bugzilla.wikimedia.org/show_bug.cgi?id=24911 (patch included, make sure to read all comments in the bugreport) --Cboltz 11:33, 13 April 2011 (UTC)

Tree expanded on loadEdit

I have edited the "Selectcategory.js" file such that the "collapsed" property is set to false, but the SelectCategoryList still loads collapsed.

 $j( document ).ready( function() {
       $j( "#SelectCategoryList" ).treeview( {
               collapsed: false
       });
 });

I am using version 0.7dev. My "LocalSettings.php" file includes:

$wgSelectCategoryRoot = array(
        NS_MAIN => "SDS"
);

Anyone found a way to resolve this?

You should check the bugtracker if you hit a bug ;-) I'm especially talking about Bug 27795. The patch I attached there fixes the issue. AFAIK it was only applied in trunk - if you use branches/REL_X_YY, you'll have to apply it yourself.
Oh, and of course you'll have to set $SelectCategoryMaxLevel according to your requirements ;-) --Cboltz 17:24, 15 July 2011 (UTC)
@Cbolltz - I appreciate the response. Went ahead and made the necessary changes. Had one more question. Could you elaborate more on what value the wgSelectCategoryMaxLevel variable is expecting? Thx
Nevermind, figured it out. It's an integer. I set it to 2 and it works now. Thx.

IE9 issuesEdit

For some reason, in IE9, some categories are appearing as bullets, and not appearing as a collapsible tree. This only appears as an issue with IE9 so far. IE7-8, chrome, ff all appear fine. --Heylarson 20:34, 18 July 2011 (UTC)

$wgSelectCategoryRootEdit

I'm having a difficult time figuring out how exactly $wgSelectCategoryRoot is supposed to work. I thought if i selected a parent category it would show the children categories either as a list or perhaps (even better) in a tree form. I selected my top category which has a large quantity of children.. nothing happened. the only category that showed on the page was that one category. so i tried from the other direction. selected a child thinking that maybe the code would work its way backwards.. nope just the one category.

how is one supposed to implement the use of $wgSelectCategoryRoot ?

--Kay 12:01, 10 November 2011 (UTC)

Exactly as described on the Extension page. You have to specify the parent category and should get all child categories as a tree. Maybe the tree is collapsed by default and you have to click the "+" sign?
BTW: There are several open bugreports in the bugtracker, some of them include patches. Check if one of them affects you, and use the patch (if there is one). --Cboltz 18:06, 10 November 2011 (UTC)
i went thru the bugreports and can't really find anything that matches my issue. i tried removing the root. it appears i get categories with check boxes so i can select them but not pluses. the only categories that show up are the parent categories.. there isn't a plus or anything to expand them. i'm sure i've missed something but it isn't like there are many things i need to set up so i can't imagine where i goofed.
I've seen that if a Category has spaces " ", underscore "_" must be used instead or it'll not expand the category. --Gborgonovo (talk) 16:23, 4 July 2013 (UTC)

Missing CategoriesEdit

After updating my mediawiki the displayed categories have not been equal to the list in Special:Categories. I've been checking the SelectCategoryFunctions.php and found the global variable $wgSelectCategoryMaxLevel. This variable is used for settings the depth the loop is going through. In LocalSettings I have set this variable to 5 and now all categories are displayed again. Does anybody see any problems using this variable, because it is not documented?

Maintained?Edit

Hi, just wanted to check - is Leon or Manuel maintaining this extension? There are several open bugs that need addressing. Thanks. Sumana Harihareswara, Engineering Community Manager (talk) 13:10, 21 September 2012 (UTC)

As you might have noticed, I posted several patches in bugzilla, which probably means I'm the de-facto maintainer of SelectCategory. I also added it to the migrate to git list to finally get commit access. Note that I'm not planning to invest too much time - basically I'll only do what I need for my usage of SelectCategory. I'll also accept patches ;-) --Cboltz (talk) 21:29, 6 February 2013 (UTC)
After going through several loops, the extension is finally in git :-)
I just updated the CHANGELOG and updated the version to 0.8.2 - except the version number, there's no code difference when compared to SVN --Cboltz (talk) 20:54, 28 February 2013 (UTC)


Subcat with 2 categoryEdit

Hi, this extension is really good, but i have a question ! If i have a sub cat (for example "chevrolet" with 2 category "automaker" and "cars"), if i edit a page i see the tree of categories but i see "chevrolet" under "automaker" but no under "cars" !

 - automaker
     - chevrolet
 - cars
     - chevrolet

How i can see the subcat in all catégories ? Thanks ;-)

You can't ;-)
SelectCategory only shows the category on first occurence. That's a known restriction because everything else would cause lots of problems:
* we would need to keep the checkmarks in sync (imagine a page is in the chevrolet category, and someone removes the checkmark from automaker/chevrolet, but not from cars/chevrolet - what would that mean in the end? We can't put half of the page in the chevrolet category ;-))
* it could produce endless loops (if the chevrolet category contains cars as sub category)
--Cboltz (talk) 22:07, 15 May 2013 (UTC)
Thanks for your reply but it's very problematic ! This site with the category "Manual" have 2 mothers categories : http://www.mediawiki.org/wiki/Category:Manual "MediaWiki for site admins" and "Documentation". So the structure is :
 - Top level
     - Documentation
         - Manual
     - MediaWiki for site admins
         - Manual
So if i would create an article, and if i search under "Top level", "Mediawiki for site admins", i don't see the category "Manual" ??? I must know the location of all the categories !!! :-(

{{PAGENAME}} in media comment boxEdit

Hi, love the extension but have trouble with one bit: the comment box in the file history of uploads displays the categories as {{PAGENAME}}. Here's an example. Any way I can avoid this and just display the cats? Thanks, AntiqueJewelryUniversity (talk) 09:03, 3 July 2013 (UTC)

Position / width of listbox?Edit

Hi,

after updating mediawiki from 1.16.2 to 1.23.6 and SelectCategory from 0.7dev to 0.8.2 I'm faced with the problem that the listbox is squeezed in the righthand side of the edit-options (I'm using the WikEd editor which has more detailed options than the normal editor) and is only about 100px wide. I've changed the SelectCategory.css to

#SelectCategoryBox {
   width: 400px, 100%;
   overflow: auto;

but nothing changed. Ideally I'd like the listbox to be positioned on the lefthand-side underneath the edit-buttons just as it was in my 1.16.2 installation. How can I achieve that?

jQuery is not definedEdit

When updated to MW 1.26 SelectCategory menu stared to have an erratic behavior, showing up or not at the bottom of a page, as page is refreshed, withou any apparent cause for it. In some pages never appearing at all. On further inspection the browser console was printing the error:

ReferenceError: jQuery is not defined

which pointed to the file SelectCategory.js

 $( document ).ready( function() {
	$( "#SelectCategoryList" ).treeview( {
		collapsed: true
	});
} );

Here is an example of a page where this is happening http://beyond-social.org/wiki/index.php?title=Business_you_can%27t_wait_for&action=edit The extension was working fine in MW 1.25.

Any ideas of how this can be solved? cheers

--Ad (talk) 14:52, 11 August 2016 (UTC) This bug is still existing in 1.26.x. Help !

The sortkey is ignored at Extensions:SelectCategory where was defined at [[Category:Names|sort]]Edit

I use the extension of SelectCategory in Chinese and it works very well. However, when displaying sub-categories, the specified sortkey is ignored, it was defined at Mediawiki [[Category: Names | sort]],just like a b c or 1 2 3....Thus disrupting the original sorting. —— Especially some categories need to be arranged in chronological order,not in pagename. I hope to solve this problem in the near future. Thanks.--Onlyou408 (talk) 08:20, 22 March 2019 (UTC)
