The BreadCrumbs2 extension generates "breadcrumbs" to help users navigate around your wiki (assuming it has a structure suitable for navigation). Breadcrumbs inserts a single line navigation string before a page's content. A sample breadcrumb for this page is shown in pale yellow above.

This extension creates breadcrumbs in the category-based "Where am I?" sense;[1] use Extension:JSBreadCrumbs for breadcrumbs in the traditional "How did I get here?" sense.

For each page the extension can use the categories and/or namespace to:

  1. Insert a single line navigation string before a page's content
  2. Highlight the active sidebar link and/or tab
  3. Change the site logo
Breadcrumbs use a single line of text to show a page's location in the site hierarchy... Breadcrumbs have always been a secondary navigation aid... All that breadcrumbs do is make it easier for users to move around the site, assuming its content and overall structure make sense.[2]

BreadCrumbs2 is especially useful with skins like GuMax that display the navigation bar as a row of tabs at the top of the page instead of the Discussion/Edit/History tools.

Использование

The breadcrumb data is stored in a page in the MediaWiki namespace, MediaWiki:Breadcrumbs. To access the page, either enter "MediaWiki:Breadcrumbs" into the search box on your wiki and click the search icon, or copy and paste the link [[MediaWiki:Breadcrumbs]] into a page, then open and edit. The contents are formatted as a wikitext list, with one line per breadcrumb option: 

* category name @ breadcrumb wikitext @ tab name @ site logo

Extra blanks between parameters are ignored.

Avoid adding unnecessary blank lines between entries in the breadcrumb list.
Parameter Type Description
category name Обязательно For each line in the list, see if the current page is a member of the category that matches category or the namespace with the same name.
breadcrumb wikitext По желанию Text to display in the subtitle with the page name appended
tab name По желанию The tab (navigation) bar with the name tab name that matches category is marked as active.
site logo По желанию Use a different site logo for this page. (Note: Use this option with care)

Навигация

The extension inserts a single line navigation string before a page's contents.[3]

Jakob Nielsen strongly encourages web designers to use the '>' character to delimit breadcrumb levels.[2]

For example, 

* Hook extensions @ [[Main Page|MediaWiki.org]] > [[:Category:Extensions|Extensions]] >

Generates the following breadcrumb for this page:

MediaWiki.org > Extensions > BreadCrumbs2

Note that BreadCrumbs2 uses the first match with the current page's namespace or one of the page's categories. For example, if the Breadcrumbs page contains: 

* Navigation extensions @ [[Main Page|MediaWiki.org]] > [[:Category:Extensions|Extensions]] > [[:Category:Navigation extensions|Navigation]] >
* User interface extensions @ [[Main Page|MediaWiki.org]] > [[:Category:Extensions|Extensions]] > [[:Category:User interface extensions|User interface]] >

The breadcrumbs for this page would be MediaWiki.org > Extensions > Navigation > BreadCrumbs2 and not MediaWiki.org > Extensions > User interface > BreadCrumbs2 because the Navigation line comes first.

Боковое меню

The active link in the navigation sidebar can be highlighted using the tab name parameter, if specified. This is especially useful with skins like GuMax that display the navigation bar as a row of tabs at the top of the page instead of the Discussion/Edit/History tools.

Note
The tab name is compared to the actual text displayed in the sidebar, so it is not language-independent.

If the site logo parameter is specified, an alternate image file is used instead of the site default. The path to this image is relative to the root of your wiki.

Note
Use this feature with caution so that it doesn't interfere with your site's usability. Subtle changes are good, but dramatic changes can be confusing. If your site needs significantly different look and feel between sections, consider using namespaces and namespace-specific styles and/or DynamicSkin.

Загрузка

You can download the extension code, in .tar.gz format, via Special:ExtensionDistributor.

You can also download the code directly via Git from the MediaWiki source code repository. From a command line, you can call the following: 

git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/BreadCrumbs2.git

To view the code online, including version history for each file, go here.

Установка

  • Скачайте и распакуйте файл(ы) в папку с названием BreadCrumbs2 в вашей папке extensions/.
    Вместо этого разработчикам и соавторам кода следует установить расширение из Git, используя:cd extensions/
    git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/BreadCrumbs2
  • Добавьте следующий код в конце вашего файла LocalSettings.php : 
    wfLoadExtension( 'BreadCrumbs2' );
  • Configure as required.
  • Create a new page called "MediaWiki:Breadcrumbs"
  •   Готово – Перейдите на страницу Special:Version на своей вики, чтобы удостовериться в том, что расширение успешно установлено.

Настройка

$wgBreadCrumbs2RemoveBasePageLink

If breadcrumbs are defined for this page, remove the link back to the base page. Defaults to "false".

$wgBreadCrumbs2HideUnmatched

If no breadcrumbs are defined for this page, show nothing. Defaults to "false".

Tips, tricks, and hoops

  • The breadcrumb list in MediaWiki:Breadcrumbs defines all the categories and subcategories used for navigation.
  • The extension uses the '@' character to delimit parameters instead of '|' as used in MediaWiki:Sidebar. This greatly simplifies the use of conditional templates in the breadcrumb list.
  • If some of your users don't like the breadcrumbs, they can hide it with some CSS (see Manual:$wgAllowUserCss):
#breadcrumbs2 {
   display: none;
}

Technical details

The breadcrumbs are built from the data page as follows:

  1. The string '@@@' is stripped from the text to be replaced with '@' before output (since the '@' character is used as a delimiter)
  2. Pseudo-variables of the form @@VAR@@ are evaluated.
    • @@USERID@@: User ID, blank if anonymous
    • @@USERGROUPS@@: Comma-delimited list of groups this user belongs to
  3. Templates and variables in the text are expanded. You can use parser functions like #if: if installed.
  4. The extension scans each line to find the first match with the current page's namespace or one of the page's categories.
  5. The remainder of the line is evaluated to set the breadcrumb string, sidebar, and/or logo (see below)
