Help:Magic words

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 usually written as 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 [[<tvar|manual-subst>Special:MyLanguage/Manual:subst</>|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

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.

Word	Description
Table of contents
__NOTOC__	Hides the table of contents (TOC).
__FORCETOC__	Forces the table of contents to appear at its normal position (before the first header, overriding __NOTOC__).
__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. 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. Use of this in a template will extend the effect to that template, the pages it's included on, and any other templates included on the same page. For a workaround, see here.
__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).
__NONEWSECTIONLINK__	Removes the link beside the "edit" tab on pages in talk namespaces.
Categories
__NOGALLERY__	Used on a category page, replaces thumbnails in the category view with normal links.
__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).
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
__INDEX__	Tell search engines to index the page (overrides $wgArticleRobotPolicies but not robots.txt). It obeys $wgExemptFromUserRobotsControl variable.
__NOINDEX__	Tell search engines not to index the page (i.e. do not list in search engines' results). It obeys $wgExemptFromUserRobotsControl variable.
__STATICREDIRECT__	On redirect pages, don't allow MediaWiki to automatically update the link when someone moves a page and checks "Fix double redirects" (which requires $wgFixDoubleRedirects).
__NOGLOBAL__	Disables the global user page. If present on the central user page, will prevent it from being displayed on remote wikis, and it also determines whether a link to a user page on remote wiki should be red or blue.

Variables

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.

Date and time

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.

Variable	Output	Description
Year
{{CURRENTYEAR}}	2026	Year
Month
{{CURRENTMONTH}}	05	Month (zero-padded number)
{{CURRENTMONTH1}}	5	Month (unpadded number)
{{CURRENTMONTHNAME}}	May	Month (name)
{{CURRENTMONTHNAMEGEN}}	May	Month (genitive form)
{{CURRENTMONTHABBREV}}	May	Month (abbreviation)
Day
{{CURRENTDAY}}	11	Day of the month (unpadded number)
{{CURRENTDAY2}}	11	Day of the month (zero-padded number)
{{CURRENTDOW}}	1	Day of the week (unpadded number), 0 (for Sunday) through 6 (for Saturday)
{{CURRENTDAYNAME}}	Monday	Day of the week (name)
Time
{{CURRENTTIME}}	17:07	Time (24-hour HH:mm format)
{{CURRENTHOUR}}	17	Hour (24-hour zero-padded number)
Other
{{CURRENTWEEK}}	20	Week (number)
{{CURRENTTIMESTAMP}}	20260511170743	YYYYMMDDHHmmss timestamp

The following variables do the same as the preceding ones but using the site's server config or <tvar|manual-wg-localtimezone>$wgLocaltimezone.

• {{LOCALYEAR}}
• {{LOCALMONTH}}
• {{LOCALMONTH1}}
• {{LOCALMONTHNAME}}
• {{LOCALMONTHNAMEGEN}}

• {{LOCALDAY}}
• {{LOCALDAY2}}
• {{LOCALDOW}}
• {{LOCALDAYNAME}}
• {{LOCALTIME}}
• {{LOCALHOUR}}
• {{LOCALWEEK}}
• {{LOCALTIMESTAMP}}

Technical metadata

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

Variable	Output	Description
Site
{{SITENAME}}	Vietnam Veterans for Factual History	The wiki's site name ($wgSitename).
{{SERVER}}	https://wiki.vvfh.org	Domain URL ($wgServer).
{{SERVERNAME}}	wiki.vvfh.org	Subdomain and domain name (no longer dependent on $wgServerName as of version 1.17).
{{DIRMARK}} {{DIRECTIONMARK}}	‎ ‎	Outputs a Unicode directional mark that matches the wiki's default language's direction (‎ on left-to-right wikis, ‏ on right-to-left wikis), useful in text with multi-directional text. Since 1.19, it depends on the page content language.
{{SCRIPTPATH}}		Relative script path ($wgScriptPath).
{{STYLEPATH}}	/skins	Relative style path ($wgStylePath).
{{CURRENTVERSION}}	1.42.1	The wiki's MediaWiki version.
{{CONTENTLANGUAGE}} {{CONTENTLANG}}	en en	The wiki's default interface language ($wgLanguageCode).
Page
{{PAGEID}}	6979	Returns the page identifier.
{{PAGELANGUAGE}} {{#language:{{PAGELANGUAGE}}}}	en English	Returns the language of the current page. The language code that this variable returns can be converted to a language name using {{#language:...}}.
{{PROTECTIONLEVEL: action}}		Outputs the protection level (e.g. "autoconfirmed", "sysop") for a given action (e.g. "edit", "move") on the current page. Returns an empty string if not protected.
{{PROTECTIONEXPIRY: action}}		Outputs the protection expiry (e.g. "20160418155030", "infinity") for a given action (e.g. "edit", "move") on the current page. Returns "infinity" if not protected.
{{CASCADINGSOURCES}}		[ Expensive] Returns the sources of any cascading protection acting on the current page. Pages will not return their own title unless they transclude themselves.
Latest revision to current page
{{REVISIONID}}	22296	Unique revision ID.
{{REVISIONDAY}}	25	Day edit was made (unpadded number).
{{REVISIONDAY2}}	25	Day edit was made (zero-padded number).
{{REVISIONMONTH}}	10	Month edit was made (zero-padded number as of 1.17+, unpadded number in prior versions).
{{REVISIONMONTH1}}	10	Month edit was made (unpadded number).
{{REVISIONYEAR}}	2017	Year edit was made.
{{REVISIONTIMESTAMP}}	20171025212359	Timestamp as of time of edit.
{{REVISIONUSER}}	Schmehl	The username of the user who made the most recent edit to the page, or the current user when previewing an edit.
{{REVISIONSIZE}}	58434	The size (bytes of wikitext) of the current revision of this page
Affects page content
code2>|noerror}} {{DISPLAYTITLE:title|noreplace}}		Format the current page's title header. The value must be equivalent to the default title: only capitalization changes to certain parts of the title (not all) and replacing spaces with underscores are allowed (this can be changed with manual-wg-restrict-disp-title $wgRestrictDisplayTitle). It can be disabled or enabled by manual-wg-allow-disp-title $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.
code1>}} {{DEFAULTSORTKEY:</>sortkey<tvar|code2>}} {{DEFAULTCATEGORYSORT:</>sortkey<tvar|code3>}} {{DEFAULTSORT:</>sortkey<tvar|code4>|noerror}} {{DEFAULTSORT:</>sortkey|noreplace}}		Used for categorizing pages, sets a default [[<tvar|help-categories>Special:MyLanguage/Help:Categories</>|category sort key]]. For example if you put <tvar|sort>{{DEFAULTSORT:</>Smith , John<tvar|sort-end>}}</> 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 <tvar|sort2>defaultsort</> do nothing if a <tvar|sort3>defaultsort</> was already specified earlier in the page.

Statistics

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}} → 4,355 and {{NUMBEROFPAGES:R}} → 4355).

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.

Variable	Output	Description
{{NUMBEROFPAGES}}	4,355	Number of wiki pages.
{{NUMBEROFARTICLES}}	248	Number of pages in content namespaces.
{{NUMBEROFFILES}}	47	Number of uploaded files.
{{NUMBEROFEDITS}}	18,646	Number of wiki edits.
{{NUMBEROFVIEWS}}
{{NUMBEROFUSERS}}	15	Number of registered users.
{{NUMBEROFADMINS}}	1	Number of users in the sysop [[<tvar|manual-userrights>Special:MyLanguage/Manual:User rights</>]].
{{NUMBEROFACTIVEUSERS}}	3	Number of active users, based on the criteria used in Special:Statistics.
{{PAGESINCATEGORY:categoryname}} {{PAGESINCAT:categoryname}}	85 85	[ Expensive] Number of pages (including subcategories and files) in the given category. (Category:Help used for demonstration)
code1>|all}} {{PAGESINCATEGORY:</>categoryname<tvar|code2>|pages}} {{PAGESINCATEGORY:</>categoryname<tvar|code3>|subcats}} {{PAGESINCATEGORY:</>categoryname|files}}	85 84 1 0	[ Expensive] Respectively, the number of all pages ordinary pages (excluding subcategories and files) subcategories or files in the given category. (Category:Help used for demonstration)
code1>}} {{NUMINGROUP:</>groupname}}	2 2 ({{NUMBERINGROUP:bureaucrat}} used here)	Number of users in a specific group.
code1>}} {{PAGESINNAMESPACE:</>index}}	Not enabled	[ 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 manual-wg-allow-slow-parser-funct $wgAllowSlowParserFunctions.

Page names

Variable	Output	Description
{{FULLPAGENAME}}	Help:Magic words	Namespace and full page title (including all subpage levels).
{{PAGENAME}}	Magic words	Full page title (including all subpage levels) without the namespace.
{{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.
{{SUBPAGENAME}}	Magic words	The subpage title ("bar" on "Help:Title/foo/bar").
{{SUBJECTPAGENAME}} {{ARTICLEPAGENAME}}	Help:Magic words Help:Magic words	Full page name of the associated subject (e.g. article or file). Useful on talk pages.
{{TALKPAGENAME}}	Help talk:Magic words	Full page name of the associated talk page.
{{ROOTPAGENAME}}	Magic words	Name of the root of the current page. Would return Title on page Help:Title/Foo/Bar

The {{BASEPAGENAME}} and {{SUBPAGENAME}} magic words only work in namespaces that have subpages enabled. See manual-wg-ns-with-subpages $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:

If the page title contains any parts that are "." or "..", the magic word fails returning nothing. {{PAGENAME:one/./three}} → '. Nothing is returned.

Warning:

pic>{{PAGESINCATEGORY:{{PAGENAME}}}}</>. See bugs T16779, T18474, T37628, and T37746. One simple way to fix this is wrapping the pagename in <tvar

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}}
• {{ROOTPAGENAMEE}}

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

Namespaces

Variable	Output	Description
{{NAMESPACE}}	Help	Name of the page's namespace
{{NAMESPACENUMBER}}	12	ID of the page's namespace
{{SUBJECTSPACE}} {{ARTICLESPACE}}	Help Help	Name of the associated content namespace
{{TALKSPACE}}	Help talk	Name of the associated talk namespace

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:MediaWiki}} → (Pages in main space will return empty)
• {{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)

Other

Variable	Output	Description
{{!}}	|	Used to include a pipe character as part of a template argument or table cell contents. Before this was added as a magic word, many wikis implemented this by creating Template:! with | as the content.

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 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.

*When the given param is equal to the current title of the parser, the parser function will yield the previous versions on preview and on substitution, that includes empty strings when used on page creation but using the values from the current version for page view, including viewing old revisions. In this case it is a non-expensive parser function.

{{anchorencode: string}}	{{anchorencode:x y z á é}} → x_y_z_á_é	The input encoded for use in URL section anchors (after the “#” symbol in a URL).

Namespaces

{{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".

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

Formatting

Usage	Input → Output	Description
{{formatnum:unformatted number}} {{formatnum:formatnum-formatted number|R}} {{formatnum:unformatted number|NOSEP}}	Simple: {{formatnum:987654321.654321}} → 987,654,321.654321 {{formatnum:987,654,321.654321|R}} → 987654321.654321 Advanced: {{formatnum:{{formatnum:987654321.654321}}|R}} → 987654321.654321 (on any locale) {{formatnum:00001}} → 00,001 {{formatnum:987654321.654321 |NOSEP}} → 987654321.654321 Examples with বাংলা locale: {{formatnum:987654321.654321}} → ৯৮,৭৬,৫৪,৩২১.৬৫৪৩২১ {{formatnum:987654321.654321 |NOSEP}} → ৯৮৭৬৫৪৩২১.৬৫৪৩২১ {{formatnum:৯৮,৭৬,৫৪,৩২১.৬৫৪৩২১ |R}} → 987654321.654321 Unsupported: {{formatnum:{{formatnum:987.654.321}}}} → 987 654 321 (e.g. with Italian locale) Examples of wrong input (unreliable output), with or without |R: {{formatnum:987,654.321|R}} (the least broken) {{formatnum:987.654,321|R}} {{formatnum:987 654,321|R}} {{formatnum:987&nbsp;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 which are known to be formatted exactly as formatnum formats them with the wiki's locale. 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. Warning: ext-pf>Extension:ParserFunctions</> installed. Warning: If you don't input numbers in the exact format required, don't expect any reliable output, especially on non-English wikis. 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). Be aware that this is more a hack than a regular way to proceed, thus the output may be not reliable.
{{#dateformat:date}} {{#formatdate:date}} {{#dateformat:date|format}} {{#formatdate:date|format}}	{{#dateformat:25 dec 2009|ymd}} → 2009 December 25 (your pref), 2009 Dec 25 (default) {{#formatdate:dec 25,2009|dmy}} → 25 December 2009 (your pref), 25 Dec 2009 (default) {{#dateformat:2009-12-25|mdy}} → December 25, 2009 (your pref), December 25, 2009 (default) {{#formatdate:2009 dec 25|ISO 8601}} → 2009-12-25 (your pref), 2009-12-25 (default) {{#dateformat:25 decEmber|mdy}} → December 25 (your pref), DecEmber 25 (default) 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: 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).
{{lc:string}}	{{lc:DATA CENTER}} → data center	The lowercase input.
{{lcfirst:string}}	{{lcfirst:DATA center}} → dATA center	The input with the very first character lowercase.
{{uc:string}}	{{uc:text transform}} → TEXT TRANSFORM	The uppercase input.
{{ucfirst:string}}	{{ucfirst:text TRANSFORM}} → Text TRANSFORM	The input with the very first character uppercase.
{{padleft:xyz|stringlength}} {{padleft:xyz|strlen|char}} {{padleft:xyz|strlen|string}}	{{padleft:xyz|5}} → 00xyz {{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|stringlength}} {{padright:xyz|strlen|char}} {{padright:xyz|strlen|string}}	{{padright:xyz|5}} → xyz00 {{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.

{{#tag: tagname |content |attribute1=value1 |attribute2=value2 }}	(Depends on parser tag)	Alias for XML-style MediaWiki parser tags or extension tags. It allows a pre-save transform of wiki code and Extension:ParserFunctions within tags before the tag is processed. It also prevents parsing of tags in conditional paths that aren't executed (like in #if statements). Content between tags is passed as the first parameter, and any attributes for the tags can be passed as subsequent parameters. This example: <tagname attribute1="value1" attribute2="value2"></>Your content goes here</tagname> …can be rewritten like this: {{#tag:tagname|Your content goes here|attribute1=value1|attribute2=value2<tvar|code5>}}</> Example for the Cite extensions's <ref> tags: < {{#tag:ref|Citation text goes here, and you can include parser functions like {{#expr: ... }} and magic words like {{PAGENAME}}.|name="multiple"}} Warning: You must write {{#tag:tagname||attribute1=value1|attribute2=value2}} to pass an empty content. No space is permitted in the area reserved for content between the pipe characters || before attribute1.
