我已为我的群组创建了自定义角色。 我已经为该特殊角色分配了一个用户，该用户是该组的成员。 现在，我想通过PHP访问组中的用户角色，但我无法在任何地方找到它 我仔细研究了用户和组的级别。我可以在用户的group_audience数组中访问用户是该组的成员这一事实，但不能访问他们的角色在该组中的内容。
有什么建议吗？

编辑：首先有一些背景，然后实际答案就在那之后。
查看我们的开发服务器上的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。
og og_membership og_membership_type og_menu og_role og_role_permission og_users_roles field_data_og_membership_request field_revision_og_membership_request 他们的定义如下：

（我已从两个field_*表中删除了空的Extras列以避免水平滚动。）希望有帮助吗？
我不得不在自己的Drupal网站上弄乱这个问题，结果发现og_membership每个组中的每个用户都有一行（我缩写为type，其中读取{ {1}}）：
og_membership_type_default在此行中，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)
是表id的自动增量标识符，og_membership对应于相关用户的etid和users.uid }对应于相关论坛的gid。
所以，如果我运行查询
og.gid然后组＃324的所有成员都被移动到组＃38（这是我刚才需要做的，因为导入脚本中有错误。）
我认为 您的问题的答案是update og_membership set gid = 38 where gid = 324;
对应og_membership.type。看那张桌子：
og_membership_type.name，我认为 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)
对应og_membership_type.status：
og_role.rid所以我认为您想要的查询是：
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)
其中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 = $group_id;
是相关群组的$group_id。 （网址中显示的ID是og.gid，因此您可能希望向该查询添加另一个og.etid。
