network_admin_url( string $path = '', string $scheme = 'admin' )

Retrieves the URL to the admin area for the network.

Parameters

$path

(string) (Optional) path relative to the admin URL.

Default value: ''

$scheme

(string) (Optional) The scheme to use. Default is 'admin', which obeys force_ssl_admin() and is_ssl(). 'http' or 'https' can be passed to force those schemes.

Default value: 'admin'

Return

(string) Admin URL link with optional path appended.

More Information

  • The network_admin_url template tag retrieves the URL to the Network Admin area for the current site with the appropriate protocol, “https” if is_ssl() and “http” otherwise. If $scheme is “http” or “https”, is_ssl() is overridden.
  • If the site is not setup as multisite, admin_url() will be used instead.
