Check which content types that are used in a group

Hi!
I have already created the views for all Groups and all content types (i.e. URL:'node/$group/ContentTypeA').
Now I want to display a link to the view (on the group home page) if that specific Group is using that content type.

Don't know how to do this:

The short, quick answer is to simply do a database query to the tables this module owns as all of the data you want is there.

Could someone help me with this?

Thanks!
Seth

This works, but maybe someone has something smarter?

I added this code in my override of the Group (node-group.tpl.php):

    $current_group = $node->nid;
    $path = dirname($_SERVER['PHP_SELF']);

    //Print link to 'Views' of content types that are active in the group

   //Check in the database
    $active_content_types = db_result(db_query("SELECT types_active FROM {og_content_type_admin} WHERE gid = %d", $current_group));

    if (empty($active_content_types)) { //If the group has the default settings
       $active_content_types = db_result(db_query("SELECT types_active FROM {og_content_type_admin} WHERE gid = %d", 0));
    }

    //content type 'image'
    $image_required = '"image";i:2';
    $image_allowed = '"image";i:1';
    if(strstr($active_content_types,$image_required) || strstr($active_content_types,$image_allowed)) {
    print '<a href="' .$path. '/node/' .$current_group. '/gallery">Image Gallery</a>';
    }

I search for the string '"image";i:X'
Where X can be: 0, 1 or 2
'i:0' not allowed by site admin or not activated by group manager
'i:1' allowed by site admin and activated by group manager
'i:2' required by site admin

If the content type 'image' is required or allowed in the current group I print a link to the view 'gallery'.

Thanks,
Seth
