That scenario should not come up. Groups are not reciprocal and they
are not necessarily public. A user who wants to set the group
permission of a socnet object should only see his personal groups in
the drop down. Just because you've added me to one of the group lists
you want to maintain doesn't mean I can see that group. The socnet
plugin will need to figure out how to differentiate between "Jakh's
Private List of People He Sends Joke Links To" and "The New Jersey
PHP User Group". In the first case, the list is only used by Jakh to
create Links and share them with Jakh's friends. The people on the
list see the links but cannot examine the list since it's private.
The second list is obviously supposed to be public and every member
of that list should be able to set permissions of an object to
include that list.
This is why the core code stays away from user owned groups. The
context of what the user owned groups mean is not understood by core.
It is only understood by the socnet plugin. In my original proposal
there were several kinds of groups and rules for inviting people into
public groups and approval systems for groups and how reciprocal
friendship works, and so on. None of that is in the patch. The patch
contains only what is minimally sufficient to allow all of that stuff
to be written as part of a plugin. Someone still has to come up with
all those rules and determine how they will be enforced and how they
will be conveyed to the user via the browser. None of that is core's business.
As the feature request in the bug tracker explains, there is a
downside to this. Currently there is a global in Geeklog $_GROUPS. It
contains the list of all groups the currently logged on user is a
member of. It is used by SEC_inGroup to determine if the current user
is a member of a group. It is also commonly used in SQL statements of
the form: "WHERE group_id in (" . explode(',', $_GROUPS) . ')'; to
select a set of objects to which the current user has permission to
view. That all is unchanged. The problem is the dropdown box created
by SEC_getGroupDropdown. This function also attempts to use the
$_GROUPS array to create a list of <option> tags for a <select>
block. The problem is that this is not the right way to go about it.
Just because I am in your friend list doesn't mean I should be able
to create objects visible to all your friends or any of the other
friend lists I'm on.
So the simple solution is to force SEC_getGroupDropdown into
Administration only duty. It only returns system groups. If you need
a list of groups that should appear in a dropdown list with the
socnet plugin's approval, the socnet plugin will need to provide a
function that does that. My guess is there will be a gl_socgroup
table in the database. At the moment I assume it would just contain
grp_id and grp_type fields but I could see other fields being added
as the socnet plugin needs control data for its groups.
