Re: Adding footer to subdomains outside WPMU/BP?
@cocomozlo – If you just want static content in the footer – site information, credits, privacy notice, etc – your best bet is to copy the HTML produced by BuddyPress, put it into its own file, and then require it in your subdomains with a normal PHP require statement.
If you want dynamic information (latest posts, activity, etc) it’s going to be trickier. Those widgets are populated dynamically by WordPress, and so require WordPress to be loaded. The easiest way to make it work would be to load WP/BP in the background of your subdomains and then use the footer PHP provided by BP. You can start WP by requiring wp-load.php in the root of your WP directory.
Requiring WP on every page load is pretty intensive, though, especially if you’re running another CMS altogether on other subdomains. It’d be good to avoid it. A possible method: Write a BP function that writes the footer to a static file and refreshes it periodically, then include that html page in your subdomains. See http://blog.slaven.net.au/archives/2007/02/01/timing-is-everything-scheduling-in-wordpress/ for more on scheduling events (like a cache) in WP; check out a plugin like https://wordpress.org/extend/plugins/wp-cache/ for an example of WP caching in action.
