Per-blog registrations for Wordpress-mu
Nathan Kinkade, July 1st, 2008
About a year ago when I started at Creative Commons, I was asked to write a Wordpress-mu plugin that would allow users to register with specific sub-blogs and not just the root/default blog. So I wrote a plugin that allowed that to happen and also fixed a few inconsistencies that I noticed in the code at that time.
Recently I reviewed my old posts at the Wordpress-mu forums and realized that there was some activity on those posts that I hadn’t noticed. It became clear that the plugin needed some modification and also that it only supported per-blog registrations for Wordpress-mu installs based on subdomains, but didn’t work for installs based on subdirectories.
This past weekend I took another look at the plugin and found that most of the inconsistencies I had been seeing, and for which I had tried to code around in the plugin, were gone in v1.5.1, and so I was able to remove the vast majority of the plugin’s code.
The current plugin seems to work for both subdomain-based and subdirectory-based installs, at least on a fresh install of Wordpress-mu that I was working with.

Really hope the plug-in continues to get support and updates.

I have been working on something like this since I installed MU 3 months ago. I refuse (well hate too) change core file source code. Been there, done that. This is beautiful.
I need to make a few changes still. For instance, it still asked whether I want to create a blog. What happens if I choose that option?
I will probably comment that out if I can’t figure out a way to optionally do it in the plugin.
Thanks.

January 31st, 2009 at 23:24 +0000I installed the plugin in the mu-plugins and the plugins folder and I see no options for it.
I tried subdomain.domain.com and maindomain.com wp-signup.php and I saw nothing different.
Am I missing something. It’s a great idea and I’d love to see it working.

February 17th, 2009 at 07:13 +0000I have installed latest version of WPMU (v-2.7) and found this plugin not working. Somehow the plugin action hook “wpmu_activate_user” is not executing and hence not updating the DB table user_meta with the sub-blog data.
Not sure how this plugin has broken on WPMU-2.7 whereas working good on WPMU-2.6.5
Any help shall be highly appreciated.
Thanks!

June 20th, 2009 at 10:54 +0000I am interested in a port to WPMU 2.7 too… Any outlook? Willing to help out but not actually need some pointers to get started. Thanks :)

August 14th, 2009 at 21:23 +0000I don’t think so. CC isn’t really using the features of the plugin anymore, or at least it’s importance has gone way down so I haven’t touched it in over a year. However, I still get emails and comments about it, so I have been thinking about getting it working with 2.8.x just as a service to the WP-mu community. We’ll see how my time and motivation come together. :-)
