Multi Site: Native support for using "domain mapping" including setting subdirectories

[schlimpf]

Multi site is a great feature and this feature needs to be extended.
Not only subdomain or (exclusive or) subdirectory installs should be possible, but also the combination of these two, better yet with different domains, not only subdomains.

Ive just run a few tests and it seems to be possible to set different domains when choosing "subdirectory" install.
I did not find this information anywhere in the documentation. Are there any drawbacks when doing so?

Thanks for the related tickets.
But as far as I see, the MU Domain Mapping plugin is not needed anymore, or am I wrong?

Hi @schlimpf, thanks for the ticket!

I don't think that 'domain mapping' as provided by a plugin such as WordPress MU Domain Mapping is something that should be in core. However, the ability to use arbitrary domains/paths for sites—removing the need for domain mapping in most cases—seems more realistic. We've made some good progress in cleaning up the bootstrap process in this release (see #27003) to further improve support.

As you mentioned, it is possible to do some of this already, especially with the use of a custom sunrise.php file. The bootstrap and database have support. The biggest problem is the lack of a UI for entering arbitrary domains/paths.

It would be worth reading through ​the potential roadmap for multisite for more brainstorming material.

Hi jeremyfelt,

thank you very much for this article. It really cleared some questions about how multi site currently works.
Maybe I am misusing the term "domain mapping". In fact, I just mean the possibility to set a site's domain and also it's subdirectory. Which should - in my oppinion - be somehow supported in the core (which is also described in the article you linked)
As I found out (see my first comment), this seems to be possible with the current version 3.8.2 (see here: ​http://postimg.org/image/trqf49173/).
Are there any things to take care of when changing a site's domain?

From what I currently tested it does what I want, without any custom sunrise.php.
I also tested the MU Domain Mapping plugin, but I don't see any benefit when using it. I do not need a site's user to change the domain, because it will be used for a company site, which will be administrated only by one user.

Related #22383, #31240, which would close this ticket though are technically not duplicates. :)

[jeremyfelt]

I'm going to close this out in favor of #22383 (in which arbitrary domain/path is possible when editing a site) and #31240 (in which the same will be possible when adding a site).
