Problem: <\/strong>
\nRegistration possible only for the Main Blog with Setting „User Accounts Registration only“.
\nRequired: Users can register for multiple Sub Blogs. <\/p>\n

Use Case: A Faculty member set up different blogs. Students were assigned to write posts
\non these blogs. They registered and had subscriber status for the Main Blog. Now they
\nwere manually added to the desired blog. With approximately 100 students there is a lot to
\ndo. So it would be nice to have students automatically sign up for a specific blog. <\/p>\n

First solution<\/strong>:
\nWPMU Per-Blog Registrations Plugin by Nathan Kinkade:
\nhttp:\/\/code.creativecommons.org\/viewsvn\/wordpressmu\/trunk\/mu-
\nplugins\/per_blog_registrations\/perBlogRegistrations.php?view=log
\nThis did not work for us. Users still got redirected to the Main Blog with wp-signup.php. <\/p>\n

Second solution:<\/strong>
\nPrerequisite:
\nSub Blog Setting is „Users can Register“: 1 <\/p>\n

Changes in wp-login.php:
\n1) In the Main part in case ‚register‘ two lines should be commented out: wp_direct and
\nexit. These are the lines responsible for redirecting to wp-sign-up with the Main Blog.
\nIf the redirect does not take place, users can register with the Sub Blog.
\ncase ‚register‘ :
\n\/\/ WPMU doesn’t use this
\n\/\/wp_redirect( get_bloginfo(‚wpurl‘) . ‚\/wp-signup.php‘ );
\n\/\/exit;
\nWith these changes users can register only once for one Sub Blog. For another Sub Blog
\nthey would have to log in with a new account. To allow students to register with multiple
\nSub Blogs further changes have to be made in wp-login.php. <\/p>\n

2) For multiple Sub Blog Registration the function „register_new_user“ is supplemented
\nby the following request: If a user is already registered username and email both have to
\nbe existent. If they both exist, the user is added as a subscriber to the blog:
\nFollowing the line: $user_email = apply_filters( ‚user_registration_email‘, $user_email );
\nthese lines are added: <\/p>\n

if( username_exists( $user_login ) && email_exists( $user_email ) )
\n{
\n$userid = username_exists( $user_login );
\nadd_user_to_blog( $current_site->blog_id, $userid, „subscriber“);
\n}
\nelse
\n{
\nThe closing bracket is placed after return $user_id; <\/p>\n

3. What does the user get? The user goes to register for the Sub Blog and fills in his or her
\nusername and email adress. With first time registering a password is sent to the person’s
\nemail adress. If already registered, there is no password sent. So it would be nice to read <\/p>\n","protected":false},"excerpt":{"rendered":"
