[wp-hackers] Regional Author Groups and Permission

Hi, David,

For your purposes, I would definitely discourage using multi-site (see
many reasons why). But you'll definitely need to write some code to
make all this happen with Events Calendar Pro.

Here's how I would probably go about it:

1. Have a way to assign users to groups (one of the groups plugins you've
tried probably does this reasonably well). You don't really need this to
manage permissions, jut manage the assignment of users to groups.

2. To prevent users from editing events from other groups: Write some code
that hooks into 'user_has_cap'. If the current user isn't in the same group
as the author of the event, remove caps like 'edit_tribe_event',
'delete_tribe_event', etc.

3. To only show events for the current user's group: Add in a
'pre_get_posts' filter in the admin. You'll get a list of users in the
current user's group, and add their IDs to the 'author' query var.

Have a nice day,
