Multisite

Hi Evelyne, it depends on what you want to do. I may be able to give a better response if you provide more details.

I need two WordPress sites (on the same server) connecting to the same CiviCRM installation (in a seperate database also on the same server).

The users should be the same for both sites (and are also contacts in CiviCRM) and they need to be able to log in on both sites with the same credentials.

Okay, that sounds like a multisite install to me… my question is really what you want this plugin to achieve in that multisite context? Is it just the First Name, Last Name and Email sync?

They want the users to be able to login with the same username/email and password on both sites.

And once logged in they should be able to access there own stuff in CiviCRM, regardless of on which of the two sites they are logged in.

But I don’t start from a clean sheet. There is already one site with CiviCRM (site 1) and on that site 1 I already have your plugin in use to sync the CiviCRM contacts with the WP users. It’s one on one, every contact is a user and vice versa.

Now I am asked to make site 2.

I am trying to figure out in advance what will happen if I convert site 1 to a WP multisite.
Does Profile Sync makes new users for site 2? (that’s not what I need)

Does Profile Sync makes new users for site 2?

No, there is (by default) only one user table in WordPress.

Just to add that there would be additional complexity if you use separate CiviCRM “domains” per WordPress site – these can be very useful for more granular permissions when domains have been mapped to sites. If you don’t need different behaviours per site, then you should be fine as is.

I would recommend reading the activation docs for further information.
