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

Has someone tried it on 1.6.8?
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 categories
I think it's better if categories aren't removed from the edit box. I've sumitted a batch at 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

Fatal Error
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)

Considerations
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 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.

 * 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)

Enhancement
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)

Bug When Category Name Has Space In It
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)

New install - No category list
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 --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)
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

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

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

then all works well

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

Bug on no categories selected

Existing categories bug
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 '_'

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 Edit
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...

[19-Sep-2007 14:12:21] PHP Notice: Undefined index:  SelectCategoryList in C:\htdocs\wkbv_wiki\extensions\SelectCategory\SelectCategoryFunctions.php on line 92

If I remove SelectCategory extension from the LocalSettings.php all works fine....

Any ideas, or should I go back to manually editing categories. --Markw21 16:43, 19 September 2007 (UTC)

Fix for trimming white space
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.
