Details edit

These are alternate names for the primary localized namespace names, which are defined by $wgExtraNamespaces and the language file. If a page is requested with such a prefix, the request will be redirected to the primary name.

Set this to a map from namespace names to IDs. Example:

$wgNamespaceAliases = [
	'Wikipedian' => NS_USER,
	'Help' => 100

To add a single alias:

$wgNamespaceAliases['WP'] = NS_PROJECT;

If you need an alias for the project you probably need a similar alias for its talk page and you should add an array as above or two lines:

$wgNamespaceAliases['WP'] = NS_PROJECT;
$wgNamespaceAliases['WP_talk'] = NS_PROJECT_TALK;
Prior to MediaWiki 1.17, it was impossible to make an alias to NS_MAIN.

If this setting is set to a namespace that does not exist (e.g. the namespace has not been added to $wgExtraNamespaces but a constant has been defined) the alias will redirect to the main space.

Do not use spaces edit

Use underscores instead of spaces in namespace names. 'My Namespace' is an invalid name; use 'My_Namespace' instead.
