問題 开启的任务 · 报告错误

CategoryTree扩展以动态树视图的形式提供了wiki的分类结构。它使用AJAX依據需要加载树的某些部分。CategoryTree最初是由Daniel Kinzler作为外部工具编写的,但后来在Tim Starling的帮助下被集成到MediaWiki软件中。

安裝

  • 下载文件,并将解压后的CategoryTree文件夹移动到extensions/目录中。
    开发者和代码贡献人员应从Git安装扩展,输入:cd extensions/
    git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/CategoryTree
  • 将下列代码放置在您的LocalSettings.php 的底部:
    wfLoadExtension( 'CategoryTree' );
    
  •   完成 – 在您的wiki上导航至Special:Version,以验证已成功安装扩展。

用法

类别树可以下列三种方式使用:

  • 直接用于分类页面,
  • 作为“自定义标签”(或“解析器函数”)在wiki页面中内联显示分类结构,
  • 作为特殊页面。

类别树扩展为分类页面上列出的子分类添加了以“展开”小部件。

<categorytree>标签

实例结果可以在下面和右侧的框中看到:

<categorytree mode="pages">Manual</categorytree>

此扩展包含一个称为<categorytree>的自定义标签。例如,如果您将<categorytree>Foo</categorytree>添加到wiki页面上,它将在该页面上将分类Foo的内容显示为动态树(参见右侧示例)。该标签使用类HTML的语法接受以下属性:

mode
定义在树中显示哪些页面。这可能通过使用namespaces选项被覆盖。可选值有:
categories
只显示子分类(配置常数0
pages
显示子分类和页面,不包括图像(配置常数10),最多显示200个页面
all
显示所有页面、子分类和图片等。(配置常量20
parents
列出父分类而非子分类(配置常量100)。这会让CategoryTree进入“反向”操作(自2008年7月的r36892起支持)。
depth
确定初次显示树的多少层。默认为1。0表示仅显示根节点。最大值取决于指定的mode和$wgCategoryTreeMaxDepth选项。(在2007年3月30日的r20410r20840被引入,自2008年7月的%rev3起即便开启$wgCategoryTreeDynamicTag也能正常运行。)
onlyroot
set this to "on" to only show the "root" node of the tree initially. Equivalent to depth="0". (Introduced in r20385, March 13 2007.) Deprecated as of r36864, July 2008: use depth="0" instead.
hideroot
将此设为“on”可隐藏树的“根”节点,即hideroot=on。例如,这将不会显示分类名Foo。
hideprefix
确定何时应从树中的条目中隐藏命名空间前缀(自2008年7月的r36864起)。可选值有:
always
always hide the prefix. Should be used only if all pages come from the same namespace (configuration constant 10).
never
never hide the namespace prefix, not even for categories (configuration constant 0).
auto
hide the namespace of categories if only categories are shown, as with mode="categories" (configuration constant 30). This is equivalent to the old default behavior (before Jun 2008).
categories
always hide the namespace of categories, but show all other prefixes (configuration constant 20). This is the new default behavior (since r36864, July 2008).
showcount
set this to "on" to show the number of entries in subcategories, i.e. showcount="on" (since r36864, July 2008). This is disabled per default for category trees inlined on pages, but enabled per default in category listings and on Special:CategoryTree.
notranslations
set this to "on" to hide all translations pages corresponding to the pages pertaining to the category, i.e. notranslations="on" (since Gerrit change 526234, November 2019). This is disabled by default. If this option is set to "on", instead of the different translations (e.g. Page, Page/en, Page/fr, Page/de) only the standard translation "Page" is displayed and all translations are suppressed.
This doesn't affect "showcount", so still a bug.
namespaces
a list of namespaces from which pages should be shown in the tree (since r36864, July 2008). The entries in the list must be namespace names, separated by spaces. The main namespace can be represented by "-" or "0". Subcategories will be shown only if Category namespace is present on the list.
class, style, id, etc
The ‎<categorytree> tag supports all standard HTML attributes for block elements (since r36864, July 2008; before that, only style was supported).

“namespaces”参数的注意事项

Category is a namespace. Categories are shown in all modes by default, but specifying the namespaces parameter hides them just like any other namespace not present on the list. If you want to list pages in a given namespace, including pages in subcategories, simply add Category to the namespace list.

例如:

  • Listing main namespace pages in Category:Manual:
<categorytree mode="pages" namespaces="Main">Manual</categorytree>
  • Listing main namespace pages and subcategories in Category:Manual:
<categorytree mode="pages" namespaces="Main Category">Manual</categorytree>

The mode parameter is overridden by namespaces:

  • if only Category namespace is asked, it's equivalent to mode=categories;
  • if file namespace is present on the list, it will imply mode=all;
  • otherwise mode=pages will be used. It means that if the site configuration hasn't been changed, the following are equivalent (the first two are always equivalent, the third only if $wgCategoryTreeDefaultMode is the default CategoryTreeMode::CATEGORIES):
<categorytree mode="categories">Manual</categorytree>
<categorytree namespaces="Category">Manual</categorytree>
<categorytree>Manual</categorytree>

{{#categorytree}}解析器函数

r25825(2007年9月13日)起,您还可以使用"解析器函数"语法在页面上放置分类树。该功能就像<categorytree>标签一样,是使用不同的语法,例如{{#categorytree:Foo}};可使用命名模板参数的语法指定选项,例如{{#categorytree:Foo|hideroot|mode=pages}}

Using the parser function syntax has the advantage that it allows you to use magic words, templates and template parameters when specifying the category to show. Some examples:

  • Using a magic variable to show this page's category tree (may be useful on category description pages): {{#categorytree:{{PAGENAME}}}}.
  • Using a template to specify the category: {{#categorytree:{{root category}}}} - the name of the root category would be defined by the contents of Template:Root_category.
  • Using a template parameter to specify the category, when using CategoryTree inside a template: {{#categorytree:{{{1}}}}} in Template:Baz can be called using {{Baz|Foo}}.

Special:CategoryTree页面

The special page is called Special:CategoryTree; there you can enter the name of a category and then browse its content.

配置

There are some options you can specify in your LocalSettings.php file.

You can no longer use CT_* constants in LocalSettings.php. Instead use 0 for category mode, 10 for pages, 20 for all, 100 for parents.
$wgCategoryTreeMaxChildren
maximum number of children shown in a tree node. Default is 200.
$wgCategoryTreeAllowTag
enable <categorytree> tag. Default is true.
$wgCategoryTreeDynamicTag
loads the first level of the tree in a <categorytree> dynamically. This way, the cache does not need to be disabled. Default is false.
$wgCategoryTreeDisableCache
disables the parser cache for pages with a <categorytree> tag, or provides max cache time in seconds. Default is 21600 which is 6 hours.
$wgCategoryTreeUseCache
enable HTTP cache for anon users. Default is false.
$wgCategoryTreeOmitNamespace
do not show the namespace name for pages and categories. Default is false, namespaces are shown unless showing categories only. Deprecated as of r36864, July 2008: use $wgCategoryTreeDefaultOptions['hideprefix'] instead.
$wgCategoryTreeMaxDepth
an array defining the maximum depth for each mode, to which the tree may be expanded initially using the depth parameter in a <category> tag. By default, this is set to 2 for the "categories" mode, and 1 for other modes. To set it to 3 for categories and 2 for other modes, for example, you can use $wgCategoryTreeMaxDepth = [10 => 2, 20 => 2, 0 => 3, 100 => 2];.
$wgCategoryTreeDefaultMode
the default mode to use when no mode attribute is specified in a <categorytree> tag. May be 0 (the default - categories), 10 (pages), or 20 (all).
$wgCategoryTreeCategoryPageMode
the mode to use when rendering trees on category pages. Deprecated as of r36864, July 2008: use $wgCategoryTreeCategoryPageOptions['mode'] instead.
$wgCategoryTreeSidebarRoot
root category to use for integrating the category tree in the sidebar (since r36920, July 2008). If not set, no tree is integrated (this is the default). Integrating a CategoryTree into the sidebar only works with skins based upon SkinTemplate, that is, Modern, Monobook, Chick, Simple, and MySkin, but not Standard, Nostalgia or CologneBlue. This is currently broken for MediaWiki 1.35.1 and the vector skin, see phab:278306.
$wgCategoryTreeDefaultOptions
default options to apply, as an array (since r36864, July 2008). The available options are described above. Example: $wgCategoryTreeDefaultOptions['mode'] = 'pages';.
$wgCategoryTreeCategoryPageOptions
options to use on category pages, as an array (since r36864, July 2008).
$wgCategoryTreeSpecialPageOptions
options to use on Special:CategoryTree, as an array (since r36864, July 2008).
$wgCategoryTreeSidebarOptions
options to use when showing the tree in the sidebar, as an array (since r36920, July 2008)

系统消息

categorytree-member-num

By default, when listing subcategories on a category page, each subcategory is followed by an integer, indicating how many subcategories lie beneath it, how many pages it contains, and how many files are in the category (if applicable):

My category name (5 C, 2 P, 1 F)

You can change this behavior by overriding the system message MediaWiki:Categorytree-member-num. It takes five parameters:

参数 含义
$1 子分类数
$2 文章数(不包括分类页面和文件页面)
$3 上传文件的个数
$4 成员页面总数,包括分类页面和文件页面
$5 Something close to ($1 C, $2 P, $3 F) but with anything that is 0 omitted.

More precisely, a comma separated list of the number of pages (mediawiki:categorytree-num-pages), subcategories (mediawiki:categorytree-num-categories), and files (mediawiki:categorytree-num-files) in the category, or empty (mediawiki:categorytree-num-empty) in the case the category has no members. In versions prior to those around 1.19 this value was different. See older version of these docs.

默认值为($5)

Tip: Use the ParserFunctions extension to provide if/then/else logic to display different parts conditionally. For example:

{{#ifeq:$1|0||$1 categories}}

A configuration to manage commas and spaces when outputting all info:

Abbreviation version:

({{#ifeq:$4|0|empty|{{#ifeq:$1|0||$1 C{{#ifeq:{{#expr:$3+$2}}|0||,}}}} {{#ifeq:$2|0||$2 P{{#ifeq:$3|0||,}}}} {{#ifeq:$3|0||$3 F}}}})

Full name version:

({{#ifeq:$4|0|empty|{{#ifeq:$1|0||$1 categories{{#ifeq:{{#expr:$3+$2}}|0||,}}}} {{#ifeq:$2|0||$2 pages{{#ifeq:$3|0||,}}}} {{#ifeq:$3|0||$3 files}}}})

故障排除

安装CategoryTree后wiki损坏

  • Turn on error reporting
  • Make sure you have all files installed
  • Make sure all of the CategoryTree extension files have mode 644, and the CategoryTree directory has mode 755.

LocalSettings.php中的选项无效

  • Make sure you specify the options after including the extension.

<span id="Clicking_the__has_no_effect,_gives_a_JavaScript_error_or_just_sits_on_loading">

点击后无效,返回JavaScript错误或处于加载中

  • Note that using the <categorytree> tag in system messages (MediaWiki namespace) may not work as expected - this is a known caveat. For a workaround, see Using CategoryTree in the Sidebar below.
  • Make sure you have $wgUseAjax = true; in your LocalSettings.php before including the extension.
  • If you are using rewrite rules or aliasing (e.g. to have "very short URLs" - i.e. wiki pages in the document root or perhaps redirecting to a www-version of the requested URL), make sure you have an exception in place for the /extensions directory, just like you would for the /skins directory. Also see below.

<span id="Clicking_the__shows_no_sub-categories_error">

点击显示no sub-categories错误

  • Try to fix this by adding this code to LocalSettings.php: $wgCategoryTreeDefaultOptions['namespaces'] = [ 0, NS_CATEGORY, NS_FILE ];

浏览器报告CategoryTree.js和/或CategoryTree.css的错误MIME类型

  • Make sure your web server uses the correct MIME types for .js and .css files
  • Enter the URLs directly into the browser and see if it is serving the pages at all, and not some error page; especially:
  • If you are using rewrite rules or aliasing (e.g. to have "very short URLs" - i.e. wiki pages in the document root), make sure you have an exception in place for the /extensions directory, just like you would for the /skins directory.

<span id="Member_counts_are_wrong,_grey_arrows__are_shown_instead_of_">

成员数错误,显示为灰色箭头而非

Since MediaWiki 1.13, CategoryTree can show the number of members of a category, and can show a grey arrow for tree nodes that do not have any children based on that number. This information is based on the new category table. However, populating that table with the current values does not always work when upgrading to 1.13. In that case, run the populateCategory.php maintenance script, if necessary with the --force option.

<span id=" _toggles_shown_only_on_the_first_level_of_the_category_tree_view">

开关仅显示在分类树视图的第一层级

In case you get only one level depth while visualing the tree, try to set in modules/ext.categoryTree.styles.css file display: none; to display: inline !important;.

The JavaScript intended to switch the tag style is somehow buggy.

机器人用户请注意

Bots and scripts that parse the HTML of category pages can use the notree URL parameter to force the traditional output. However, HTML output is generally not stable, so it is recommended to change your script to use the API to fetch category listings and similar.

“Category Not Found”消息

After you implement the CategoryTree plugin and add the code to show the tree, if you see a message that says Category Not Found, you need to add some content in your category pages. The category pages can't be red pages, basically. Click your category names, add some text in the category page, and then your tree should work fine.

后面的200个链接在安装了CategoryTree后不起作用

Make sure the right version of this extension is installed, relative to the version of MediaWiki you have installed. In particular, versions of this extension made for versions of MediaWiki prior to 1.17 are not compatible with MediaWiki 1.17 and greater, and will cause issues where all the paging links on category pages are broken.

使用“namespaces”参数时不显示任何页面

Hacks

在系统消息和自定义皮肤中使用CategoryTree

In older versions of CategoryTree, you have to modify the code to make this work: find the efCategoryTreeParserOutput function in the file CategoryTree.php, and remove the condition; i.e. it should then look like this:

function efCategoryTreeParserOutput( &$outputPage, &$parserOutput )  {
    CategoryTree::setHeaders( $outputPage );
    return true;
}

在侧边栏使用CategoryTree

通过JavaScript

Since r36920 (July 2008) with MediaWiki 1.13 (r36917), you can integrate a CategoryTree in the sidebar simply by setting $wgCategoryTreeSidebarRoot to the category you want to use as a root. This only works with skins based upon SkinTemplate however, that is, Modern, Monobook, Chick, Simple, and MySkin, but not Standard, Nostalgia or CologneBlue.

If you want the CategoryTree on a different position in the sidebar, you can reference it on MediaWiki:Sidebar as "categorytree-portlet".

For earlier versions of CategoryTree and/or MediaWiki, you'll need to install a mod to MonoBook.php to enable normal wikitext in the sidebar, see Wikitext in side bar --DJ 19:26, 24 January 2008 (UTC)

To append a link "CategoryTree" to your toolbox (sidebar ) add following code to the JavaScript page (e.g. monobook.js) of your skin and customize the URL "w:Special:CategoryTree".

function AppendCategoryTreeToSidebar() {
    try {
        var node = document.getElementById( "p-tb" )
                           .getElementsByTagName('div')[0]
                           .getElementsByTagName('ul')[0];
 
        var aNode = document.createElement( 'a' );
        var liNode = document.createElement( 'li' );
 
        aNode.appendChild( document.createTextNode( 'CategoryTree' ) );
        aNode.setAttribute( 'href' , '[[w:Special:CategoryTree]]' );
        liNode.appendChild( aNode );
        liNode.className = 'plainlinks';
        node.appendChild( liNode );
    } catch(e) {
        // lets just ignore what's happened
        return;
    }
}
 
addOnloadHook( AppendCategoryTreeToSidebar );

A more generic version of this code can be found at Manual:Interface/Sidebar#content of sidebar and toolbox (javascript) .

Step by step if works easy:

$wgCategoryTreeSidebarRoot = 'Category:article_name';

通过MediaWiki: 命名空间页面

If you want to create a link that goes to the generic categorytree (displayed as Category tree) when you're on a non-category page, and to a particular categorytree (displayed as View as category tree, with foo being the name of the category you're viewing) when you're on a category page:

  • Add to your MediaWiki:Sidebar (right above the SEARCH is a good place) a line, ** sidebarcategorytree-url|sidebarcategorytree
  • Create a [[MediaWiki:Sidebarcategorytree]] with, say: {{#ifeq: {{NAMESPACE}}|Category|View as category tree|Category tree}}
  • Create a [[MediaWiki:Sidebarcategorytree-url]] with, say: {{#ifeq: {{NAMESPACE}}|Category|Special:CategoryTree/{{BASEPAGENAME}}|Special:CategoryTree/Categories}}
