Function: is_site_admin

is_site_admin( string $user_login )

Determine if user is a site admin.

Plugins should use is_multisite() instead of checking if this function exists to determine if multisite is enabled.

This function must reside in a file included only if is_multisite() due to legacy function_exists() checks to determine if multisite is enabled.


Name Type(s) Default Value Description
$user_login string ''

Optional. Username for the user to check. Default empty.
