Help:Sub pages

You can create sub pages, that will automatically have a link back to the container page.

to create a page that is highly related to the parent page, and contains a link back to the parent page automatically.

Use

They are primarily used for archiving old talk pages, and documents for non-current versions

Deprecated use

but could be used for redirection (but Categories handle this more naturally)

 History/United Kingdom  could point to History of United Kingdom
 United Kingdom/History could also point to History of United Kingdom.

sub pages are not used in the main namespace, because...? (see Help:Subpages )

Restrictions

• Sub pages are enabled for the User namespace by default, but not the main namespace (see below)
• The entire "Top_Page/subpage/other_subpage" string can't be more than 255 characters, including the slashes.

How to do it

• Just put a "/" as the first character of your /wikilink, and it will be equivalent to:

Sub pages/wikilink

• Note that if you don't have subpages enabled for that namespace, you'll create a top-level page whose name begins with '/'.

See Help:Link#Subpage feature.

Administration

sub pages must be enabled for the Namespace !

Enabling in main name space

An easy way to enable subpages in the main namespace is to edit your LocalSettings.php and insert the following:

# Enable subpages in the main namespace
$wgNamespacesWithSubpages[NS_MAIN] = true;

This overrides the DefaultSettings.php setting for namespace 0. In this manner you can override any single namespace without overriding more than you need to.

Namespace names

The names for namespaces are set in files such as those listed in Locales for the Wikimedia projects, with default Language.php:

/* private */ $wgNamespaceNamesEn = array(
	NS_MEDIA            => 'Media',
	NS_SPECIAL          => 'Special',
	NS_MAIN	            => '',
	NS_TALK	            => 'Talk',
	NS_USER             => 'User',
	NS_USER_TALK        => 'User_talk',
	NS_WIKIPEDIA        => $wgMetaNamespace,
	NS_WIKIPEDIA_TALK   => $wgMetaNamespace . '_talk',
	NS_IMAGE            => 'Image',
	NS_IMAGE_TALK       => 'Image_talk',
	NS_MEDIAWIKI        => 'MediaWiki',
	NS_MEDIAWIKI_TALK   => 'MediaWiki_talk',
	NS_TEMPLATE         => 'Template',
	NS_TEMPLATE_TALK    => 'Template_talk',
	NS_HELP             => 'Help',
	NS_HELP_TALK        => 'Help_talk',
	NS_CATEGORY	    => 'Category',
	NS_CATEGORY_TALK    => 'Category_talk'
);
