Anyone have any idea how one would be able to ‘bridge’ the user database of multiple bbPress sites?

Example:

1) Someone signs up to post on bbPress site 1.

2) The same user name and login works on bbPress site 2.

3) Likewise, someone who signed up on site 2 can login and post under site 1.

Is this possible or simply a pipedream?

Any plugins or site features in the works for something like that?

It is very simple. I will explain to you how to do it. Use 1 WordPress MU site for the database and then integrate each bbpress with cookies and user database integration. It works fine. I’ve done it!

Thanks Rohan. Here’s the thing, I don’t want separate blogs for each of the bbPress sites, just different domains with bbPress installs on each. Would this be possible via WPMU & bbPress?

If you integrate all the bbPress installs to use the same users table, then you can let your users sign in even if your bbPress installs are on separate domains… if you use ck’s awesome “Cross Cookie” plugin:

It only works in bbPress 0.9 though…

Dang. So for bbPress 1.0+ you must go WPMU, huh?

[@johnhiler Member 15 years, 5 months ago]

All the Cross Cookie plugin does is automatically sign you into multiple domains with a single login.

If you just want to have all your bbPress installs share a single user table, you should be able to do that in any version of bbPress!

Not sure on the connection to wpmu…

johnhiler, you have been most helpful. How exactly would you recommend one do this?

Would one simply point each separate bbPress installation to the same MYSQL table during initial setup?

Is there any danger in one site overwriting another with this sort of setup?

[@johnhiler Member 15 years, 5 months ago]

There’s some useful tips here!

Definitely backup all your data before playing around… it should be pretty safe to have multiple installs use the same user table.

If you hit a snag, post and let us know and I’ll see if I can help. I integrated multiple bbpress installs of 0.9 not 1.0, but if it’s not too different maybe I can help. I’ve got almost 10 bbPress installs working together with a single users database, so there’s definitely a path!

Note that cross-cookie does not work (yet) with bbPress 1.0

It will also not work with any other plugin that modifies cookies (ie. year long cookies)
