在WordPressMU中,如何允许用户使用现有帐户注册新博客?

我做了自己的插件。它可能不是最优雅的代码,但它满足了我的需要:

function set_user_role($blog_id,$user_id)
{
    $users = get_users();
    // register each user to the new website.
    foreach($users as $user=>$userid)   
    {
        if($user_id == 1)
        {
            add_user_to_blog( $blog_id, $userid, "administrator" );
        }
        //auto register a new user for all previous blogs.But will this create duplicates for existing users? Nope. It doesn't! 
        else if($user_id == $userid)
        {
            //add_user_to_blog( $blogid, $user_id, "administrator" );
            $blogs = get_blogs();
            foreach($blogs as $blog=>$blogid)   
            {
                //if this is the blog the user just created, then let them be an admin.
                if($blogid == $blog_id )
                    add_user_to_blog( $blogid, $user_id, "administrator" );
                else
                    add_user_to_blog( $blogid, $user_id, "subscriber" );
            }
        }
        else
            add_user_to_blog( $blog_id, $userid, "subscriber" );//if user is not an admin and not a new user, then just make them a subscriber.
    }
}

function get_users()
{
    global $wpdb;
    $userids = $wpdb->get_col( $wpdb->prepare("SELECT $wpdb->users.ID FROM $wpdb->users ORDER BY %s ASC", $szSort ));
    return $userids;
}

function get_blogs()
{
    global $wpdb;
    $blogids = $wpdb->get_col( $wpdb->prepare("SELECT blog_id FROM $wpdb->blogs WHERE site_id = %d  AND archived = '0'  AND spam = '0' AND deleted = '0' ORDER BY path", $wpdb->siteid));
    return $blogids;
}

//When a new blog is created, auto-register all unblocked users for it.
add_action('wpmu_new_blog','set_user_role', 100, 2); 

或者,如果他们是现有用户,只需将他们发送回yourdomain.com/wp-signup.php即可。那个;默认情况下,他们可以在这里创建自己的新博客。
