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.

There are three general types of magic words:

  • Behavior switches: these are uppercase words surrounded by double underscores (eg __FOO__)
  • Variables: these are uppercase words surrounded by double braces (eg <tt>{{FOO}}</tt>). As such, they look a lot like templates
  • Parser functions: these take parameters and are either of the form <tt>{{foo:...}}</tt> or <tt>{{#foo:...}}</tt>.

Page-dependent magic words will affect or return data about the current page, even if the word is added through a transcluded template or included system message.

Behaviour switches

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

Word Description Versions
Table of contents
__NOTOC__ Hides the table of contents (TOC).
__FORCETOC__ Forces the table of content to appear at its normal position (above 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.
Editing
__NOEDITSECTION__ Hides the section edit links beside headings.
__NEWSECTIONLINK__ Adds a link ("+" by default) 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+
Categories
__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+
Language conversion
__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).
Other
__START__ No effect.
__END__ Explicitly marks the end of the article, to prevent MediaWiki from removing trailing whitespace. Removed in 19213.
__INDEX__ Tell search engines to index the page (overrides $wgArticleRobotPolicies, but not robots.txt). 1.14+
__NOINDEX__ Tell search engines not to index the page (ie, do not list in search engines' results). 1.14+
__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". 1.13+

Variables

Variables return information about the current page, wiki, or date. Their syntax is similar to templates. 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 treat a variable as a template; for example, {{CURRENTDAYNAME|x}} transcludes Template:CURRENTDAYNAME.

Date & time

The following variables return the current date and time according to the user's timezone preferences, defaulting to the UTC timezone.

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

Variable Output Description Versions
Year
{{CURRENTYEAR}} 2024 Year
Month
{{CURRENTMONTH}} 11 Month (zero-padded number)
{{CURRENTMONTHNAME}} November Month (name)
{{CURRENTMONTHNAMEGEN}} November Month (genitive form)
{{CURRENTMONTHABBREV}} Nov Month (abbreviation) 1.5+
Day
{{CURRENTDAY}} 22 Day of the month (unpadded number)
{{CURRENTDAY2}} 22 Day of the month (zero-padded number) 1.6+
{{CURRENTDOW}} 5 Day of the week (unpadded number)
{{CURRENTDAYNAME}} Friday Day of the week (name)
Time
{{CURRENTTIME}} 07:09 Time (24-hour HH:mm format)
{{CURRENTHOUR}} 07 Hour (24-hour zero-padded number)
Other
{{CURRENTWEEK}} 47 Week (number)
{{CURRENTTIMESTAMP}} 20241122070929 YYYYMMDDHHmmss timestamp 1.7+

The following variables do the same as the above, but using the site's local timezone instead of user preferences and UTC:

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

Technical metadata

Revision variables return data about the latest edit to the current page, even if viewing an older version of the page.

Variable Output Description Versions
Site
{{SITENAME}} NsdWiki The wiki's site name ($wgSitename).
{{SERVER}} https://wiki.nsdgames.com domain URL ($wgServer)
{{SERVERNAME}} wiki.nsdgames.com domain name ($wgServerName)
{{DIRMARK}}
{{DIRECTIONMARK}} 		‎
‎ 		Outputs a unicode-directional mark that matches the wiki's default language's direction (&lrm; on left-to-right wikis, &rlm; on right-to-left wikis), useful in text with multi-directional text. 1.7+
{{SCRIPTPATH}} /w relative script path ($wgScriptPath)
{{CURRENTVERSION}} 1.29.0 The wiki's MediaWiki version. 1.7+
{{CONTENTLANGUAGE}} en The wiki's default interface language ($wgLanguageCode) 1.7+
Latest revision to current page
{{REVISIONID}} 4098 Unique ID 1.5+
{{REVISIONDAY}} 8 Day edit was made (unpadded number) 1.8+
{{REVISIONDAY2}} 08 Day edit was made (zero-padded number) 1.8+
{{REVISIONMONTH}} 03 Month edit was made (unpadded number) 1.8+
{{REVISIONYEAR}} 2009 Year edit was made 1.8+
{{REVISIONTIMESTAMP}} 20090308182924 Timestamp as of time of edit 1.8+
{{PAGESIZE:page name}} 25,290 Returns the byte size of the specified page. 1.13+
{{PROTECTIONLEVEL:action}} protection level Outputs the protection level (e.g. 'autoconfirm', 'sysop') for a given action (e.g. 'edit', 'move') on the current page or an empty string if not protected. 1.15+
Affects page content
{{DISPLAYTITLE:title}} Format the current page's title header. The value must be equivalent to the default title: only capitalization changes and replacing spaces with underscores. It can be disabled or enabled by $wgAllowDisplayTitle; disabled by default before 1.10+, enabled by default thereafter. 1.7+
{{DEFAULTSORT:sortkey}} Used on a categorized page, sets a default category sort key. 1.10+

Statistics

Numbers returned by these variables normally contain separators (commas or spaces, depending on the local language), but can return raw numbers with the ":R" flag (for example, {{NUMBEROFPAGES}} → 32,146 and {{NUMBEROFPAGES:R}} → 32146). Use "|R" for magic words that require a parameter like PAGESINCATEGORY (for example {{PAGESINCATEGORY:Help}} and {{PAGESINCATEGORY:Help|R}}).

Variable Output Description Versions
Entire wiki
{{NUMBEROFPAGES}} 32,146 Number of wiki pages. 1.7+
{{NUMBEROFARTICLES}} 1,070 Number of pages in main namespace.
{{NUMBEROFFILES}} 182 Number of uploaded files. 1.5+

({{NUMBERINGROUP:bureaucrat}} used here) 		Number of users in a specific group. 1.14+
{{PAGESINNS:index}}
{{PAGESINNAMESPACE:index}} 		not enabled Number of pages in the given namespace (replace 2 with the relevant namespace index). E.g. {{PAGESINNAMESPACE:14}} equals the number of categories. Disabled by default, enable with $wgAllowSlowParserFunctions. 1.7+

Page names

Variable Output Description Versions
{{FULLPAGENAME}} Help:Magic words Namespace and page title. 1.6+
{{PAGENAME}} Magic words Page title.
{{BASEPAGENAME}} Magic words Page title excluding the current subpage and namespace ("Title" on "Title/foo"). 1.7+
{{SUBPAGENAME}} Magic words The subpage title ("foo" on "Title/foo"). 1.6+
{{SUBJECTPAGENAME}} Help:Magic words The namespace and title of the associated content page. 1.7+
{{TALKPAGENAME}} Help talk:Magic words The namespace and title of the associated talk page. 1.7+

The following are URL-encoded equivalents:

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

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

Namespaces

Variable Output Description Versions
{{NAMESPACE}} Help Namespace (name)
{{SUBJECTSPACE}}
{{ARTICLESPACE}} 		Help
Help 		Name of the associated content namespace 1.7+
{{TALKSPACE}} Help talk Name of the associated talk namespace 1.7+

The following are URL-encoded equivalents:

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

As of 1.15+, these can all take a parameter, specifying the property should be returned for a given title instead of the current page:

  • {{NAMESPACE:Template:Main Page}} -> Template

Parser functions

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 usually prefixed with a hash to distingush them from possible 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 ParserFunctions extension.

URL data

Variable Output Description Versions
{{localurl:page name}}
{{localurl:page name|query string}} 		/Page_name
/w/index.php?title=Page_name&query string 		The relative path to the title.

Formatting

Usage Output Description Version
{{lc:string}} text transform The lowercase input. 1.5+
{{lcfirst:string}} teXt tRaNsFoRm The input with the first character lowercase. 1.5+
{{uc:string}} TEXT TRANSFORM The uppercase input. 1.5+
{{ucfirst:string}} TeXt tRaNsFoRm The input with the first character uppercase. 1.5+
{{formatnum:unformatted number}}
{{formatnum:formatted number|R}} 		-987,654,321.654321
-987654321.654321 		The input with decimal and decimal group separators, and localized digit script, according to the wiki's default locale. the |R parameter can be used to unformat a number, for use in mathmatical situations. 1.7+
{{padleft:xyz|number}}
{{padleft:xyz|number|separator}} 		00xyz
__xyz 		Inserts a string of padding characters (character chosen in third parameter; default '0') of a specified length (second paramater) 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; ie. {{padleft:44|3|0}} produces 044.
bug (fixed in r45734): multibyte characters are interpreted as two characters, which can skew width. These also cannot be used as padding characters. 		1.8+
{{padright:xyz|number}}
{{padright:xyz|number|separator}} 		xyz00
xyz__ 		Identical to padleft, but adds padding characters to the right side.
{{plural:2|is|are}} are Outputs the correct given pluralization form (parameters except first) depending on the count (first parameter). Plural transformations are used for languages like Russian based on "count mod 10".
{{grammar:N|noun}} 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 Manual:$wgGrammarForms.
