:::php
Subsite::set_allowed_themes(array('blackcandy','mytheme'));
### Public display of a subsite
By default, each subsite is available to the public (= not logged-in),
provided a correct host mapping is set up. A subsite can be marked as non-public
in its settings, in which case it only shows if a user with CMS permissions is logged in.
This is useful to create and check subsites on a live system before publishing them.
Please note that you need to filter for this manually in your own queries:
$publicSubsites = DataObject::get(
'Subsite',
Subsite::$check_is_public ? '"IsPublic"=1' : '';
);
To ensure the logged-in status of a member is carried across to subdomains,
you also need to configure PHP session cookies to be set
for all subdomains:
// Example matching subsite1.example.org and www.example.org
Session::set_cookie_domain('.example.org');
