给你一个用户注册时候，添加到og的rules

1. Create an open group where your new users will be added automatically during registration.
2. Enable OG sub module "Organic groups register".
3. Add the "Add Group register field group types" to the "Open Group Node Entity" at "Home/Administration/Configuration/Organic groups/OG field setting/"
4. Add the field "og_user_group_ref" to the registration form at "Home/Administration/Configuration/People/Account settings/"
5. At "Home/Administration/Configuration/People/Account settings/Manage fields/og_user_group_ref/ check the fields "Required field" and "Display on user registration form".
6. Configure as follows: number of values: unlimited. Target-type: node. Mode: organic groups. Target bundles: open group, private group (Important: all target bundles need to be marked or you get the error that was bugging me for so long).
7. Check all your group-types and enable or disable the function "show on registration form".
8. Update your database and clear the drupal cache.
9. Try it out.
10. Use css (display: none;) to optically remove the group registration from your user registration form if you so desire.
