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 explains only the 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, e.g. __FOO__.

• Variables: these are uppercase words surrounded by double braces, e.g. {{FOO}}. As such, they look a lot like templates.

• Parser functions: these take parameters and are either of the form {{foo:...}} or {{#foo:...}}. See also Help:Extension:ParserFunctions.

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.

Behavior switches[編集]

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.

Variables[編集]

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 テンプレート:PAGENAME you would need to write {{テンプレート:PAGENAME}}). In some cases, adding parameters will force the parser to invoke a template; for example, {{CURRENTDAYNAME|x}} transcludes テンプレート:CURRENTDAYNAME, not the variable.

Date and time[編集]

The following variables return the current date and time in UTC.

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.

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

• {{LOCALYEAR}}
• {{LOCALMONTH}}
• {{LOCALMONTH1}}
• {{LOCALMONTHNAME}}
• {{LOCALMONTHNAMEGEN}}
• {{LOCALMONTHABBREV}}
• {{LOCALDAY}}
• {{LOCALDAY2}}
• {{LOCALDOW}}
• {{LOCALDAYNAME}}
• {{LOCALTIME}}
• {{LOCALHOUR}}
• {{LOCALWEEK}}
• {{LOCALTIMESTAMP}}

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

Technical metadata[編集]

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

Statistics[編集]

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}} → 1,057 and {{NUMBEROFPAGES:R}} → 1057).

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.

Page names[編集]

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

テンプレート:Warning/core 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 T16779, T18474, T37628, and T37746. One simple way to fix this is wrapping the pagename in {{#titleparts:}} from the ParserFunctions extension.

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[編集]

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}}
• {{ROOTPAGENAMEE}}

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

Namespaces[編集]

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

• {{NAMESPACEE}}
• {{SUBJECTSPACEE}}
• {{ARTICLESPACEE}}
• {{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}} → テンプレート
• {{SUBJECTSPACE:Template:Main Page}} → テンプレート
• {{TALKSPACE:Template:Main Page}} → テンプレート・トーク

Parameter must not be a namespace name:

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

Parser functions[編集]

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 Extension:ParserFunctions. For those see Help:Extension:ParserFunctions.
