Help:Variables

See also: Help:Quick reference

Variables return information about the current page, wiki, or date. Their syntax is similar to templates.

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

{{SITENAME}}	Nottinghack Wiki	The wiki's site name.
{{SERVER}}	https://wiki.nottinghack.org.uk	Domain URL.
{{SERVERNAME}}	wiki.nottinghack.org.uk	Domain name.
{{SCRIPTPATH}}		Relative path to the wiki scripts on the server.
{{STYLEPATH}}	/skins	Relative path to the wiki style sheet on the server.
{{CURRENTVERSION}}	1.42.1	The wiki's MediaWiki version.
Latest revision to current page
{{REVISIONID}}	16799	Unique revision ID
{{REVISIONDAY}}	6	Day the edit was made (unpadded number)
{{REVISIONMONTH}}	02	Month the edit was made
{{REVISIONYEAR}}	2019	Year the edit was made
{{REVISIONTIMESTAMP}}	20190206143535	Timestamp of the edit
{{REVISIONUSER}}	Jon	The user who made the most recent edit to the page, or the current user when previewing an edit
{{PROTECTIONLEVEL:action}}	protection level	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.
Affects page content
{{DISPLAYTITLE:title}}		Format the current page's title. The value must be equivalent to the default title: only capitalization changes and replacing spaces with underscores are allowed.
{{DEFAULTSORT:sortkey}} {{DEFAULTSORTKEY:sortkey}} {{DEFAULTCATEGORYSORT:sortkey}}		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.

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}} → 5,467 and {{NUMBEROFPAGES:R}} → 5467). Use "|R" for magic words that require a parameter like PAGESINCATEGORY (for example {{PAGESINCATEGORY:Help}} and {{PAGESINCATEGORY:Help|R}}). Also applicable to {{PAGESIZE:page name}} above.

Variable	Output	Description
Entire wiki
{{NUMBEROFPAGES}}	5,467	Number of wiki pages.
{{NUMBEROFARTICLES}}	973	Number of pages in content namespaces.
{{NUMBEROFFILES}}	2,653	Number of uploaded files.
{{NUMBEROFEDITS}}	28,876	Number of page edits.
{{NUMBEROFVIEWS}}	Template:NUMBEROFVIEWS	Number of page views. Usually useless on a wiki using caching.

Page name variables

Variable	Output	Description
{{FULLPAGENAME}}	Help:Variables	Namespace and page title.
{{PAGENAME}}	Variables	Page title.

{{TALKPAGENAME}}	Help talk:Variables	The namespace and title of the associated talk page.

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

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