Location-Specific Mulitsite Content?

hardcode the link in the theme.

Hmm. I’m not quite sure if that would do it, but I may be misunderstanding what you’re saying. Let me see if I can clarify and if that still seems like the answer I may have to ask for more detail from you.

Person A visits office1.domain.com. After viewing a couple of pages, he then clicks the “Blog” link in the nav menu, which redirects to blog.domain.com. Person B visits office2.domain.com and eventually clicks the “Blog” link as well, which also directs to blog.domain.com. So far so good, because they’re both seeing their specialized content first and then a shared blog second.

Here’s the catch: while viewing blog.domain.com, Person A clicks the “Office” link. This should redirect them back to office1.domain.com. But if Person B clicks the same “Office” link, it should go to office2.domain.com.

Because the link is located on the blog.* subdomain, both visitors will see the same code. So I’m not quite sure how to code that to dynamically choose which it would go to. Is there a method I don’t know of?

Or, am I going about this wrong? Is there another way to make a shared blog embed in a site, so that they’d never leave the office*.domain.com site in the first place?

Thanks!

Yeah, that’s different. It sounded like you wanted to do the opposite.

Here’s the catch: while viewing blog.domain.com, Person A clicks the “Office” link. This should redirect them back to office1.domain.com. But if Person B clicks the same “Office” link, it should go to office2.domain.com.

so you need to determine where they came from a I guess. (it’s not really multisite specific – would be similar to sending people back to language specific content)

That makes sense. So I guess the evolved question (I really didn’t do a good job explaining the first time around, did I? ?? ) is more along the lines of this: is there a way to accomplish this that IS multisite specific?

For instance, is there a way to keep track of a specific user’s “home” site? This is assuming that all sites would be part of the same multisite network, and that only a couple of admin users would be registered on the main site. So the normal user would be a member of, say, the office2 subsite and have guest access to the blog and wiki subsites. Now that I think about it, this may be easier using subdirectories rather than subdomains.

Then I could create a menu like this (including hypothetical WP function):

<a href="intranet.domain.com/blog>Blog Subsite, same for all</a>
<a href="intranet.domain.com/wiki>Wiki Subsite, same for all</a>
<a href="intranet.domain.com/<?php wp_user_home_site(); ?>/policy">Local policy manual, displayed based on user name</a>

Or some other way that WordPress could help determine this sort of thing?

AHA!

Now I get it… you CAN check for a user’s main blog.. if they are the admin of it. It’s called their primary blog.

this one might help:

or

Argh I know there’s another one…

The second one looks helpful to me. Although I’m not quite sure how it determines which blog is the primary one. It doesn’t mention the admin requirement on the codex page… is that the only way it would have a primary blog set? Or would it do the same if someone was only added as a user to one subsite, and was left as a guest on the others?
