Help:Variables
Variables return information about the current page, wiki, or date. Their syntax is similar to templates.
Most variables (except for pseudo variables below) are types of "magic words". See magic words at MediaWiki for a complete list.
Date and time
The following variables return the current date and time in UTC.
Due to software and browser caching, these variables frequently show when the page was cached rather than the current time.

{{CURRENTDAY}} | 21 | Day of the month (unpadded number) |
{{CURRENTDAY2}} | 21 | Day of the month (zero-padded number) |
{{CURRENTDOW}} | 4 | Day of the week (unpadded number) |

{{REVISIONUSER}} | Xeverything11 | The username of the user who made the most recent edit to the page, or the current user when previewing an edit |
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}}
→ 291,045 and {{NUMBEROFPAGES:R}}
→ 291045). Use "|R" for magic words that require a parameter like PAGESINCATEGORY (for example {{PAGESINCATEGORY:Help}}
and {{PAGESINCATEGORY:Help|R}}
).
Variable | Output | Description |
---|---|---|
{{NUMBEROFPAGES}} | 291,045 | Number of wiki pages. |
{{NUMBEROFARTICLES}} | 97,578 | Number of pages in content namespaces. |
{{NUMBEROFFILES}} | 2,683 | Number of uploaded files. |
{{NUMBEROFEDITS}} | 4,298,118 | Number of page edits. |
{{NUMBEROFUSERS}} | 3,479,720 | Number of registered users. |
{{NUMBEROFADMINS}} | 10 | Number of users in the administrator group. |
{{NUMBEROFACTIVEUSERS}} | 302 | Number of active users, based on the criteria used in Special:Statistics. |
{{NUMBERINGROUP:groupname}} {{NUMINGROUP:groupname}} |
0 0 ({{NUMBERINGROUP:bureaucrat}} used here) |
Number of users in a specific group. |
Namespaces
Variable | Output | Description |
---|---|---|
{{NAMESPACE}} | Help | Name 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 URLs (spaces replaced with underscores and some characters percent-encoded):
- {{NAMESPACEE}}
- {{SUBJECTSPACEE}}
- {{TALKSPACEE}}
These can take a page name and will return the namespace of the page name parameter, instead of the current page's:
- {{NAMESPACE:Template:Main Page}} → Template
- {{SUBJECTSPACE:Template:Main Page}} → Template
- {{TALKSPACE:Template:Main Page}} → Template talk
Page names
Variable | Output | Description |
---|---|---|
{{FULLPAGENAME}} | Help:Variables | Namespace and page title. |
{{PAGENAME}} | Variables | Page title, excluding namespace. |
{{BASEPAGENAME}} | Variables | Page title excluding the current subpage and namespace ("Title/foo" on "Title/foo/bar"). |
{{SUBPAGENAME}} | Variables | The subpage title ("foo" on "Title/foo"). |
{{ROOTPAGENAME}} | Variables | Title of the topmost parent, excluding namespace and anything after the first slash ("Title" on "Wikijunior:Title/foo/bar"). |
{{SUBJECTPAGENAME}} | Help:Variables | The namespace and title of the associated content page. |
{{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}}
- {{ROOTPAGENAMEE}}
- {{SUBJECTPAGENAMEE}}
- {{TALKPAGENAMEE}}
These can all allow specification of the page to be operated on, instead of just the current page:
- {{PAGENAME:Template:Main Page}} → Main Page
Pseudo variables
Some templates have been created that mimic the above variables. While the variables in the above section use a colon (:) to specify a page for output if desired, these will use a pipe (|) for inputting a page. For example, {{BOOKNAME|Wikijunior:Bugs}}
can be used to get Wikijunior:Bugs.
Template | Description |
---|---|
{{NUMBEROFBOOKS}} | Returns the number of books at Wikibooks. |
{{BOOKTEMPLATE}} | Returns the name of a template with the same name as the book it's used in. |
{{BOOKNAME}} | Returns the name of the book associated with the page on which it's used. |
{{NAIVEBOOKNAME}} | Returns the namespace and rootpagename of the page. |
{{BOOKTALKNAME}} | Returns the associated discussion page for a book as a whole. |
{{CHAPTERNAME}} | Returns the chapter that a page is in and ignores anything beyond that. |
{{BOOKPAGENAME}} | Returns all of a page name except the name of the book. |
{{BOOKSORTKEY}} | Returns all of a subpage name except the name of the book, or the book name if the page isn't a subpage. |
For the latter templates, it's easier to see the difference between them by viewing a side-by-side comparison of their outputs.
