Magic words are strings of text that MediaWiki associates with a return value or function, such as time, site details, or page names. This page is about usage of standard magic words; for a technical reference, see Manual:Magic words.

这里有三种类型的魔术字:

  • 行为转换器:这些字符被两道下划线所包围,例如__FOO__
  • 变量:这些字符被两个大括号所包围,例如{{FOO}}。用法与模板类似。

Variables and parser functions can use subst:, just like templates. Page-dependent magic words will affect or return data about the current page (by default), even if the word is added through a transcluded template or included system message.

行为开关

A behavior switch controls the layout or behavior of the page and can often be used to specify desired omissions and inclusions in the content.

文字 描述 版本
表格内容
__NOTOC__ Hides the table of contents (TOC).
__FORCETOC__ Forces the table of contents to appear at its normal position (before the first header).
__TOC__ Places a table of contents at the word's current position (overriding __NOTOC__). If this is used multiple times, the table of contents will appear at the first word's position.
编辑
__NOEDITSECTION__ Hides the section edit links beside headings. This is especially useful, where a heading is created from within a template: the normal wiki section-edit would in this case edit the template code, which is normally counterintuitive to the user. If a template contains multiple headings, it may be necessary to add "__NOEDITSECTION__" after each heading.
__NEWSECTIONLINK__ Adds a link beside the "edit" tab for adding a new section on a non-talk page (see Adding a section to the end).
1.7
__NONEWSECTIONLINK__ Removes the link beside the "edit" tab on pages in talk namespaces.
1.15
r47522
分类
__NOGALLERY__ Used on a category page, replaces thumbnails in the category view with normal links.
1.7
__HIDDENCAT__ Used on a category page, hides the category from the lists of categories in its members and parent categories (there is an option in the user preferences to show them).
1.13
语言转换
__NOCONTENTCONVERT__
__NOCC__
On wikis with language variants, don't perform any content language conversion (character and phase) in article display; for example, only show Chinese (zh) instead of variants like zh_cn, zh_tw, zh_sg, or zh_hk.
__NOTITLECONVERT__
__NOTC__
On wikis with language variants, don't perform language conversion on the title (all other content is converted).
其他
__START__ 无效
__END__ Explicitly marks the end of the article, to prevent MediaWiki from removing trailing whitespace. Removed in 19213.
1.1 – 1.8
__INDEX__ Tell search engines to index the page (overrides $wgArticleRobotPolicies, but not robots.txt). It obeys $wgExemptFromUserRobotsControl variable.
1.14
__NOINDEX__ Tell search engines not to index the page (i.e. do not list in search engines' results). It obeys $wgExemptFromUserRobotsControl variable.
1.14
r37973
__STATICREDIRECT__ On redirect pages, don't allow MediaWiki to automatically update the link when someone moves a page and checks "Update any redirects that point to the original title" (which requires $wgFixDoubleRedirects).
1.13
r37928
__DISAMBIG__ Marks a page as a disambiguation page and places it in Special:DisambiguationPages, and places inward links in Special:DisambiguationPageLinks. See Extension:Disambiguator. 需要Extension:Disambiguator

变量

Variables return information about the current page, wiki, or date. Their syntax is similar to templates. Variables marked as "[expensive]" are tracked by the software, and the number that can be included on a page is limited.

If a template name conflicts with a variable, the variable will be used (so to transclude the template Template:PAGENAME you would need to write {{Template:PAGENAME}}). In some cases, adding parameters will force the parser to invoke a template; for example, {{CURRENTDAYNAME|x}} transcludes Template:CURRENTDAYNAME, not the variable.

日期和时间

以下的变量返回当前的日期和时间,遵照用户的时区选项,默认为UTC时间。

Due to MediaWiki and browser caching, these variables frequently show when the page was cached rather than the current time.

The date and time magic words are formatted in the wiki content language. Since 1.19, they depend on the page content language.

变量 输出 描述 版本
{{CURRENTYEAR}} 2014
{{CURRENTMONTH}} 10 月(零填充数字)
{{CURRENTMONTHNAME}} 10月 月份名称
{{CURRENTMONTHNAMEGEN}} 十月 月份 (属格)
{{CURRENTMONTHABBREV}} 10月 月份 (缩写)
1.5
{{CURRENTDAY}} 24 今天是几日 (不补齐)
{{CURRENTDAY2}} 24 今天是几日 (以 0 补齐)
1.6

{{CURRENTTIMESTAMP}} 20141024144135 YYYYMMDDHHmmss时间戳
1.7

The following variables do the same as the preceding ones, but using the site's server config or $wgLocaltimezone.

  • {{LOCALYEAR}}
  • {{LOCALMONTH}}
  • {{LOCALMONTHNAME}}
  • {{LOCALMONTHNAMEGEN}}
  • {{LOCALMONTHABBREV}}
  • {{LOCALDAY}}
  • {{LOCALDAY2}}
  • {{LOCALDOW}}
  • {{LOCALDAYNAME}}
  • {{LOCALTIME}}
  • {{LOCALHOUR}}
  • {{LOCALWEEK}}
  • {{LOCALTIMESTAMP}}

For more thorough time formatting, you may want to install 扩展:ParserFunctions to use the #time parser function.

Affects page content
{{DISPLAYTITLE:标题}} Format the current page's title header. The value must be equivalent to the default title: only capitalization changes and replacing spaces with underscores are allowed (this can be changed with $wgRestrictDisplayTitle). It can be disabled or enabled by $wgAllowDisplayTitle; disabled by default before 1.10+, enabled by default thereafter.

It can take a second argument of noerror or noreplace to suppress error messages when multiple displaytitles are used on one page or to make this displaytitle do nothing if a displaytitle was already specified earlier in the page.

{{DEFAULTSORT:sortkey}}
{{DEFAULTSORTKEY:sortkey}}
{{DEFAULTCATEGORYSORT:sortkey}}
{{DEFAULTSORT:sortkey|noerror}}
{{DEFAULTSORT:sortkey|noreplace}}
Used for categorizing pages, sets a default category sort key. For example if you put {{DEFAULTSORT:Smith , John}} at the end of John Smith, the page would be sorted under "S" by default in categories. It can take a second argument of noerror or noreplace to suppress error messages when multiple defaultsortkeys are used on one page or to make this defaultsort do nothing if a defaultsort was already specified earlier in the page.
1.10

1.19

统计

Numbers returned by these variables normally contain separators (commas, dots or spaces, depending on the local language), but can return raw numbers with the ":R" flag (for example, {{NUMBEROFPAGES}} → 260,768 and {{NUMBEROFPAGES:R}} → 260768).

Use "|R" for magic words that require a parameter like PAGESINCATEGORY (for example {{PAGESINCATEGORY:Help}} and {{PAGESINCATEGORY:Help|R}}, or {{PAGESINCATEGORY:Help|subcats}} and {{PAGESINCATEGORY:Help|subcats|R}}). Also applicable to {{PAGESIZE:page name}} hereinbefore.

The number magic words are formatted in the wiki content language. Since 1.19, it depends on the page content language.

{{PAGESINNS:index}}
{{PAGESINNAMESPACE:index}}
未启用 [Expensive] Number of pages in the given namespace (replace index with the relevant namespace index). For instance, {{PAGESINNAMESPACE:14}} will output the number of category pages. {{PAGESINNS:0}} differs from {{NUMBEROFARTICLES}} in that the former includes redirects and disambiguation pages. Disabled by default, enable with $wgAllowSlowParserFunctions.
1.7

页面名称

变量 输出 描述 版本
{{FULLPAGENAME}} Help:Magic words/zh 名字空间与完整页面标题(包括子页面级别)。
1.6
{{PAGENAME}} Magic words/zh 不包含名字空间的完整页面标题(包括子页面级别)。
{{BASEPAGENAME}} Magic words Page title of the page in the immediately superior subpage level without the namespace ("Title/foo" on "Help:Title/foo/bar").

For more complex splitting, use {{#titleparts:}} from the ParserFunctions extension.

1.7
{{SUBPAGENAME}} zh The subpage title ("bar" on "Help:Title/foo/bar").
1.6
{{SUBJECTPAGENAME}}
{{ARTICLEPAGENAME}}
Help:Magic words/zh
Help:Magic words/zh
Full page name of the associated subject (e.g. article or file). Useful on talk pages.
1.7
{{TALKPAGENAME}} Help talk:Magic words/zh 关联讨论页的完整页面名称
1.7

The {{BASEPAGENAME}} and {{SUBPAGENAME}} magic words only work in namespaces that have subpages enabled. See $wgNamespacesWithSubpages for information on enabling subpages.

As of 1.15+, these can all take a parameter, allowing specification of the page to be operated on, instead of just the current page:

  • {{PAGENAME:Template:Main Page}}Main Page
Warning Warning: Page titles containing certain characters, such as apostrophes ' or asterisks *, may produce unexpected results when handled with these magic words, e.g. {{PAGESINCATEGORY:{{PAGENAME}}}}. See bugs 14779, 16474, 35628, and 35746. One simple way to fix this is wrapping the pagename in #titleparts (parser function).

For example, if page name is "L'Aquila", the following code will produce the string "Numeric char encoding":

{{#switch:{{PAGENAME}}
| L'Aquila = No translation
| L = Not OK
| L'Aquila = Entity escaping
| L'Aquila = Numeric char encoding
}}

URL encoded page names

The following are equivalents encoded for use in MediaWiki URLs (i.e. spaces replaced with underscores and some characters HTML escaped using numeric character encoding):

  • {{FULLPAGENAMEE}}
  • {{PAGENAMEE}}
  • {{BASEPAGENAMEE}}
  • {{SUBPAGENAMEE}}
  • {{SUBJECTPAGENAMEE}}
  • {{ARTICLEPAGENAMEE}}
  • {{TALKPAGENAMEE}}

Note that {{PAGENAME:...}}, {{PAGENAMEE:...}} and {{urlencode:...}} have distinct implementations. See Manual:PAGENAMEE encoding for details.

1.7

The following are equivalents encoded for use in MediaWiki URLs (spaces replaced with underscores and some characters percent-encoded):

  • {{NAMESPACEE}}
  • {{SUBJECTSPACEE}}
  • {{TALKSPACEE}}

As of 1.15+, these can take a full-page-name parameter and will return the requested namespace associated with that page, instead of with the current page:

  • {{NAMESPACE:Template:Main Page}}Template
  • {{SUBJECTSPACE:Template:Main Page}}Template
  • {{TALKSPACE:Template:Main Page}}Template talk

Parameter must not be a namespace name:

  • {{SUBJECTSPACE:Help talk}}  (Empty)

解析器函数

Parser functions are very similar to variables, but take one or more parameters (technically, any magic word that takes a parameter is a parser function), and the name is sometimes prefixed with a hash to distinguish them from templates.

This page only describes parser functions that are integral to the MediaWiki software. Other parser functions may be added by MediaWiki extensions such as the 扩展:ParserFunctions. For those see Help:扩展:ParserFunctions.

名字空间

{{ns:}} returns the current localized name for the namespace with that index, canonical name, or local alias. Thus {{ns:6}}, {{ns:File}}, and {{ns:Image}} (an old name for the File namespace) all return "File". On a wiki where the content language is French, {{ns:Fichier}} is also valid, but {{ns:Datei}} (the localisation of "File" in German) is not.

{{nse:}} is the equivalent encoded for MediaWiki URLs. It does the same, but it replaces spaces with underscores, making it usable in external links.

{{formatnum:987.654,321|R}}
{{formatnum:987 654,321|R}}
{{formatnum:987 654,321|R}}

Takes an unformatted number (arab, no group separators and . as decimal separator) and outputs it in the localized digit script and formatted with decimal and decimal group separators, according to the wiki's default locale.

The |R parameter can be used to reverse the behavior, for use in mathematical situations: it's reliable and should be used only to deformat numbers who are known to be formatted exactly as formatnum formats them with the wiki's locale.
Warning Warning:  Leading zeroes are not removed, you can use {{#expr:00001}} instead if you have 扩展:ParserFunctions installed.

Warning Warning:  If you don't input numbers in the exact format required, don't expect any reliable output, especially on non-English wikis.

Warning Warning:  The NOSEP ("no separators") parameter means that no group / decimal separators are changed; formatnum will only transform the digits themselves in languages which don't use the Hindu–Arabic numeral system. NOSEP can also prevent non-standard digit groupings you wouldn't expect.


If you really need to format (according the wiki's locale) a number in unknown input format, you could try and use formatnum two times (but not if it can have a decimal group, or its separator will be eaten or the number won't be formatted).

Note: In the example hereinbefore, "your pref" refers to your date preference on the current MediaWiki wiki only.

Formats an unlinked date based on user "date format" preference, and adds metadata tagging it as a formatted date. For logged-out users and those who have not set a date format in their preferences, dates can be given a default: mdy, dmy, ymd, ISO 8601 (all case sensitive). If only the month and day are given, only mdy and dmy are valid. If a format is not specified or is invalid, the input format is used as a default. If the supplied date is not recognized as a valid date (specifically, if it contains any metadata such as from a nested use of these or similar templates), it is rendered unchanged, and no (additional) metadata is generated.

Warning Warning: Although the ISO 8601 standard requires that dates be in the Gregorian calendar, the ISO parameter in this function will still format dates that fall outside the usual Gregorian range (e.g. dates prior to 1583). Also, the magic word cannot properly convert between negative years (used with ISO 8601) and years BC or years BCE (used in general writing).

{{padleft:xyz|5|_}} → __xyz {{padleft:xyz|5|abc}} → abxyz {{padleft:xyz|2}} → xyz
{{padleft:|1|xyz}} → x (first character of the string)
Inserts a string of padding characters (character chosen in third parameter; default "0") of a specified length (second parameter) next to a chosen base character or variable (first parameter). The final digits or characters in the base replace the final characters in the padding; i.e. {{padleft:44|3|0}} produces 044. The padding string may be truncated if its length does not evenly divide the required number of characters.

Only the first character of the third parameter is used in versions up to 1.12, but by version 1.15 all the characters are used.

Bug (fixed in r45734): multibyte characters are interpreted as two characters, which can skew width. These also cannot be used as padding characters.

{{padright:xyz|5|_}} → xyz__ {{padright:xyz|5|abc}} → xyzab {{padright:xyz|2}} → xyz
{{padright:|1|xyz}} → x

Identical to padleft, but adds padding characters to the right side.

Here are the magic words which are used as main localisation tools. Other magic words will often depend on the wiki's locale and configuration or on the chosen language: see in particular #Date and time, #Formatting, #Miscellaneous. More magic words are added by the 扩展:翻译.

The usage of these magic words can be very complex, and the documentation is currently incomplete; there's some more info on PLURAL, GRAMMAR, GENDER.

Outputs the singular form (second parameter) if the first parameter is an expression equalling one; the plural form (third parameter) otherwise. Its functioning is language-dependent.
Some language codes (ab, av, ba, bxr, ce, crh_cyrl, cv, inh, koi, krc, kv, lbe, lez, mhr, mrj, myv, ru, tt_cyrl, tyv, udm, xal) used 3 plural forms (updated 01.2014):
  • Form 1: 1, 21, 31, 41, 51, 61, 71, 81, 101, 1001, …
  • Form 2: 0, 5, 6, 7,8,...18, 19, 100, 1000, 10000, 100000, 1000000, …
  • Form 3: 2, 3, 4, 22, 23, 24, 32, 33, 34, 42, 43, 44, 52, 53, 54, 62, 102, 1002, …
{{grammar:N|noun}} Outputs the correct inflected form of the given word described by the inflection code after the colon (language-dependent). Grammar transformations are used for inflected languages like Polish. See also $wgGrammarForms.

{{gender:username|text for every gender}}

{{gender:Username|male text|female text|text for unspecified}}
{{gender:|male text|female text|text for unspecified}}
{{gender:.|male text|female text|text for unspecified}}

(Depends on the named user's gender) A switch for the gender set in Special:Preferences.

Note: The first example is basically a no-op
Note: If 3rd parameter is omitted and user hasn't defined his/her gender, then text if user is male is returned.
A blank username field ({{gender:|) means the current user.
A dot username (.) means the default user gender on this wiki.

(Depends on user language; try: fr • ja)
Internationalizes (translates) the given interface (MediaWiki namespace) message into the user language. For msgnw and other transclusion magic words, see Help:Magic words#Template modifiers.

Note that this can damage / confuse cache consistency in MediaWiki 1.17 and earlier, see bug 14404.

{{int:editsectionhint|MediaWiki}} {{int:editsectionhint|MediaWiki}}Edit section: MediaWiki You may also use parameters with translations.
Parameters are designated in messages with: $1, $2, $3, etc.
For example, here is the message for editsectionhint: Edit section: $1
In this example, MediaWiki replaces $1.
