我为我的组创建了一个自定义角色。我已经为这个特殊角色分配了一个用户，他是该组的成员。现在，我想通过 PHP 访问组中用户的角色，但我无法在任何地方找到它。
我仔细研究了用户和组的开发。我可以访问用户是用户 group_audience 数组中组成员的事实，但不能访问他们在该组中的角色。
有什么建议吗？

背景
查看我们开发服务器上的 mySQL 数据库，我们的 Drupal 数据库中似乎有一些与 OG 相关的表。我很确定在 devserver 上运行的版本是 og-7.x-1.x-dev。
ogog_membershipog_membership_typeog_menuog_roleog_role_permissionog_users_rolesfield_data_og_membership_requestfield_revision_og_membership_request
它们的定义如下所示：

（我已经从两个field_*表中删除了空的 Extras 列以避免水平滚动。）希望有帮助吗？
我的作品
在我自己的 Drupal 站点上自己搞砸了这个，结果发现og_membership每个组中的每个用户都有一行（我已经缩写了type，它读作og_membership_type_default）：
mysql> select * from og_membership where gid = 324 and etid = 182905;
+--------+-----------------+--------+-------------+-----+-------+------------+
| id | type | etid | entity_type | gid | state | created |
+--------+-----------------+--------+-------------+-----+-------+------------+
| 223562 | og_m..._default | 182905 | user | 324 | 1 | 1329388409 |
+--------+-----------------+--------+-------------+-----+-------+------------+
1 row in set (0.01 sec)
在这一行中，id是表的自动递增标识符og_membership，etid对应于users.uid相关用户的 ，gid对应于og.gid相关组的 。
所以如果我运行查询
update og_membership set gid = 38 where gid = 324;
然后组#324 的所有成员都被移动到组#38（这是我刚刚需要做的，由于导入脚本中的错误）。
我认为您的问题的答案是og_membership.type对应于og_membership_type.name. 看着那张桌子：
mysql> select * from og_membership_type;
+----+----------------------------+-------------+--------+--------+
| id | name | description | status | module |
+----+----------------------------+-------------+--------+--------+
| 1 | og_membership_type_default | Default | 2 | og |
+----+----------------------------+-------------+--------+--------+
1 row in set (0.00 sec)
，我认为og_membership_type.status对应于og_role.rid：
mysql> select * from og_role;
+-----+-----+----------------------+
| rid | gid | name |
+-----+-----+----------------------+
| 1 | 0 | non-member |
| 2 | 0 | member |
| 3 | 0 | administrator member |
+-----+-----+----------------------+
3 rows in set (0.00 sec)
实际答案
所以我认为你想要的查询是：
select og_role.name
from og_role
inner join og_membership_type on og_role.rid = og_membership_type.status
inner join og_membership on og_membership_type.name = og_membership.type
where og_membership.gid = $group_id;
$group_id有og.gid问题的组在哪里。（出现在 URL 中的 ID 是og.etid，因此您可能希望在join该查询中添加另一个 ID。
