This is a Template documentation subpage for Template:NAMESPACEID. It contains usage information, categories, and other content that is not part of the original template page.

Description

Template:NAMESPACEID/doc returns the namespace ID of page given, or of the current page.

Usage

• {{NAMESPACEID}} → 10
• {{NAMESPACEID|}} → 0 (Article namespace)
• {{NAMESPACEID|{{ns:0}}}} → 0 (Article namespace)
• {{NAMESPACEID|Talk}} → 1

Namespace aliases are accepted, too:

• {{NAMESPACEID|Image}} → 6
• {{NAMESPACEID|File}} → 6
• {{NAMESPACEID|MW}} → Invalid namespace in {{NAMESPACEID}}
• {{NAMESPACEID|Project}} → 4
• {{NAMESPACEID|Math Wiki}} → 4

Invalid input returns an error, which can be caught with the #iferror parser function:

• {{NAMESPACEID|Foo}} → Invalid namespace in {{NAMESPACEID}}
