Extension talk:Hierarchy

Instructions about templates
I wanted to mention to you that it would be more clear in your instructions on the mediawiki site if you named the 'Template:Hierarchy header' 'Hierarchy header' because in your examples, you call , not. Anyone messing around with this stuff should understand what transclusions are but I thought I would let you know the inconsistencies.

Is there any site where this extension can be seen in action?
No, sorry. But you can install it on a test site and follow the usage sample to try it out. --Fernando Correia 15:42, 1 February 2007 (UTC)

Do you think this extension will work on MW 1.6.7?

 * Well, it might. But I cannot verify that. My focus is to support the newest version. Only one way to find out... --Fernando Correia 11:31, 5 February 2007 (UTC)

OK have had a try. Some minor problems with: CREATE TABLE `mywikidb`.`hierarchy` ( `Id` int( 10 ) unsigned NOT NULL AUTO_INCREMENT,  `IndexArticleId` int( 10 ) unsigned NOT NULL ,  `TocLevel` int( 10 ) unsigned NOT NULL ,  `TocNumber` varchar( 255 ) NOT NULL ,  `TocText` varchar( 255 ) NOT NULL ,  `Sequence` int( 10 ) unsigned NOT NULL ,  `ArticleId` int( 10 ) unsigned NOT NULL ,  `PreviousArticleId` int( 10 ) unsigned NOT NULL ,  `NextArticleId` int( 10 ) unsigned NOT NULL ,  `ParentArticleId` int( 10 ) unsigned NOT NULL ,  PRIMARY KEY ( `Id` ) ,  KEY `IndexArticle` USING BTREE( `IndexArticleId` , `Sequence` ), KEY `ArticleId` ( `ArticleId` ) ) ENGINE = MYISAM DEFAULT CHARSET = latin1;

Got an error 1064 - think some problems with KEY? What version of MySQL does your extension support? Aretai 14:41, 8 February 2007 (UTC)


 * MySQL version 5. Take a look, you have to replace `mywikidb` for the name of your database. --Fernando Correia 15:35, 8 February 2007 (UTC)

Yes I know:) I've already replaced it. Well will try again, however probably just need to update my software Aretai 09:45, 9 February 2007 (UTC)


 * Probably this error is more related to MySQL than to MediaWiki. If at all possible try to update PHP, MySQL and MediaWiki. --Fernando Correia 10:40, 9 February 2007 (UTC)

Id did have this Error 1064 on MySQL - 4.0.18, too. It appears to work when you avoid "USING BTREE". I hope this has no side effects (appart from performance ones). --Francesc Hervada-Sala, 217.95.231.1 08:44, 28 May 2007 (UTC)

I cannot install the extension properly
Thank you for this extension, I think it will be very useful to me. After copying all files and configuring the LocalSettings.php as indicated, I get this warning at every page of my wiki: Warning: Cannot modify header information - headers already sent by (output started at .../extensions/Hierarchy.php:2) in .../includes/WebResponse.php on line 10 Does anyone know how to fix it? I use MediaWiki 1.10.0 --Francesc Hervada-Sala, 217.95.231.1 08:44, 28 May 2007 (UTC)

I had the same error, following the instructions with Mediawiki 1.10.0. MAW

Getting error after setup
Enabling produces the following error: Warning: Missing argument 2 for wfHierarchyParserFunction_Magic in extensions/Hierarchy.php on line 381

This line in the code from the wiki is: function wfHierarchyParserFunction_Magic( &$magicWords, $langCode ) { # Add the magic word # The first array element is case sensitivity, in this case it is not case sensitive # All remaining elements are synonyms for our parser function $magicWords['hierarchy-top'] = array( 0, 'hierarchy-top' ); $magicWords['hierarchy-bottom'] = array( 0, 'hierarchy-bottom' ); # unless we return true, other parser functions extensions won't get loaded. return true; }

Can you let me know what the workaround might be?

Is it possible to include (the first N levels of) the hierarchy in the sidebar?

Allow less than 4 items
It would be nice to remove the limitation of at least 4 items in the index. This may lead to confusion when users try to build the index incrementally. Probably a _TOC_ used internally in the index function could do it. --Fernando Correia 13:24, 9 March 2007 (UTC)

Subordinate pages in the navigation box (resolved)
Great extension! It works fine for me. However, it would be great to have the subordinate pages listed in the navigation box as well, instead of them only being displayed in the footer. 130.83.196.179 16:44, 6 March 2007 (UTC)


 * Thanks for the feedback. I agree that this would be a good idea. Probably showing as an indented bulleted list. There could be an option to have these pages on the footer, in the box, or both. --Fernando Correia 18:39, 6 March 2007 (UTC)

I have hacked the extension so as to include subordinate pages in the navigation box, can send you the modified file if you are interested. 130.83.196.179 14:36, 7 March 2007 (UTC)


 * Sure, please do! You can post it here or email it to me. --Fernando Correia 16:58, 7 March 2007 (UTC)


 * Thank you for your contribution, Felix! Version 1.1.0 is released. --Fernando Correia 17:01, 8 March 2007 (UTC)

Alternate text in index
Nice extension which helps me a lot. One thing I'm missing is to use another text in the index than the link, something like Piped Links. When using ... &lt;index&gt; [[ Top Page ]

Sample Chapter
... I get a link to Sample_Chapter, instead of Chapter1

Tried also this form a (b) but this gives an error in $page_url = $title->escapeLocalURL; Thanks for your help. --Daniel 11:26, 9 March 2007 (UTC)


 * I agree. I've already had this need also. I think this can be allowed with a little tweaking in the parser. This form should be easy to allow: == Sample Chapter == --Fernando Correia 11:11, 9 March 2007 (UTC)

That was fast! You think you might adopt this? Knowing this, I could already start using this form in my pages. Thanks --Daniel 12:25, 9 March 2007 (UTC)


 * Talk about fast. By the timestamps, it seems I'm answering them before you ask them! :-)


 * I'd definitely like to have this feature. Maybe I can take some time to take a look at it today. No promises, though. In the meantime you can create a page redirect to have an alternate name. --Fernando Correia 12:20, 9 March 2007 (UTC)

Table prefixes
It seems the extension does not work when table prefixes are used. --Fernando Correia 18:47, 4 April 2007 (UTC)


 * I haven't seen any problems using this extension and table prefixes so far (only tested on a very limited demo site), off course the CREATE TABLE statement should be altered so that the hierarchy-table has the same prefix as the other tables --wimh 13:46, 8 May 2007 (UTC)

Mediawiki 1.10
This extension is great, but it screws up the layout on Mediawiki 1.10. The Writing is huge, and there are spaces between many elements, e.g. between The page and the tabs at the top, or around the logo. --91.3.112.102 12:05, 29 May 2007 (UTC) (Die_Backe)

edit: I checked the html-code of the mainpage with and without the extension installed. Only commentarys (processing time, caching of the page) and pagefiews are different. And there is a space in the very first line. ("< !DOCTYPE" with, "<!DOCTYPE" without extension). Any idea? -- Die_Backe, 91.3.112.102 12:14, 29 May 2007 (UTC)

Blank page when user login
When a user logs in to our wiki the page is blank. When you are not logged in you can see the index page. One of my users had this problem on her machine but I could log in on my machine with her login and see the index. Now, today, I can't see the index page with her log in or my own sysops loggin. I don't know if this because of the prefixes on the table or not. It seems more like a cache issue because of how intermittant the viewing has been over the last few days.

Does anyone have any ideas? Thanks, Margaret

Back again, I think I figured out my issue. I protected the index page so no one but a sysop could edit the page and in return, it doesn't show the outline when a user is logged in. I hope this solution fixes this back and forth behavior.
