Why can't a WordPress network (multisite) in it's own folder use subdomains?

    If I’m setting up a brand new multisite installation with WordPress in it’s own folder (say /wp/) why can’t I configure the network to use subdomains instead of subfolders?

    Currently, if I try to setup the network with the WordPress core in it’s own folder I’m not allowed to choose between a subdomain-based or sub-folder based network. I must use sub-folders.

    What are the technical reasons for this? I’ve scoured trac and Google for an answer to this question with no luck. A more detailed explanation than what is provided on http://codex.wordpress.org/Before_You_Create_A_Network or http://codex.wordpress.org/Create_A_Network would be greatly appreciated.

    Thanks!

    Are you running WordPress in it’s own folder as in it’s installed in domain.com/wp and using domain.com as the URL, or do you mean it’s installed in AND runs as domain.com/wp?

    The former can use subdomains, the latter cannot.

    I haven’t bothered to deep dive into it, but my guess would be that it’s due to how WP parses the subdomain, and everything would be sub.domain.com/wp

    Hi Ipstenu,

    I mean the former and actually figured this out thanks in part to your response. It was a simple oversight.

    I setup a clean install of WordPress using Mark Jaquith’s WordPress Skeleton which places WordPress’s core files at domain.com/wp/. However, when trying to run install.php, WordPress chokes on it’s own redirects in this senario (maybe a bug report for another day).

    To get around that, I manually typed in the correct path to install.php: domain.com/wp/wp-admin/network.php. By doing this, WordPress automatically set the home URL to domain.com/wp instead of just domain.com. (Doh!) By changing the site’s home URL to domain.com, I am now able to choose a subdomain or subfolder installation when setting up the multisite.

    Thanks for your help and getting me pointed down the right track. It’s much appreciated!
