$type's accepted (eventually!):
VIEW, READ, POST, REPLY, EDIT, DELETE, VOTE, VOTECREATE
$type's accepted (pre-pend with AUTH_):
VIEW, READ, POST, REPLY, EDIT, DELETE, STICKY, ANNOUNCE, VOTE, VOTECREATE,
ATTACH
Possible options to send to auth (not all are functional yet!):
$types pending (for future versions, pre-pend with AUTH_):
ALLOW_HTML, ALLOW_BBCODE, ALLOW_SMILIES
* If you include a type then a specific lookup will
be done and the single result returned
Possible options ($type/forum_id combinations):
* If you set type to ALL an array of all auth types
* If you include a type and forum_id then a specific lookup will be done and
the single result returned
* If you set type to AUTH_ALL and specify a forum_id an array of all auth types
will be returned
* If you provide a forum_id a specific lookup on that
forum will be done
* If you provide a forum_id a specific lookup on that forum will be done
* If you set forum_id to LIST_ALL an array of all
forums to which the user has access of type will be returned
<- used for index and search? (type VIEW and READ respectively)
* If you set forum_id to AUTH_LIST_ALL and specify a type an array listing the
results for all forums will be returned
* If you set forum_id to LIST_ALL and type to ALL a
multidimensional array containing the auth permissions
for all types and all forums for that user is returned
* If you set forum_id to AUTH_LIST_ALL and type to AUTH_ALL a multidimensional
array containing the auth permissions for all types and all forums for that
user is returned
* If you set $userdata to ALL, then the permissions of all
users listed in the auth_access table will be returned for
the given type and forum_id <- use to check for moderators?
All results are returned as associative arrays, even
when a single auth type is specified
All results are returned as associative arrays, even when a single auth type is
specified.
If available you can send an array (either one or two dimensional) containing the
forum auth levels, this will prevent the auth function having to do its own
lookup
