OGUR Views Filters

hook_views_tables() was wrong. Needed to add extra parameter as in:

     /**
     * Implementation of hook_views_tables():
     * Present fields and filters for user data.
     * Requires that usernode be installed.
     */
    function og_user_roles_views_tables() {

      $group_node = og_get_group_context();
      $gid = $group_node->nid;

      $tables['og_users_roles'] = array(
        'name' => 'og_users_roles',
        'provider' => 'internal', // won't show up in external list.
        'join' => array(
          'left' => array(
            'table' => 'node',
            'field' => 'uid'
          ),
          'right' => array(
            'field' => 'uid'
          ),
          'extra' => array(
            'gid' => $gid
          ),
        ),
        'filters' => array(
          'rid' => array(
            'name' => t('OG User Roles: Role (group)'),
            'operator' => 'views_handler_operator_andor',
            'list' => 'og_user_roles_filter_role',
            'value-type' => 'array',
            'help' => t('Include the node only if the node author is a member of the selected OG group role - uses og_users_roles.'),
          ),
          'gid' => array(
            'name' => t('OG User Roles: Posts in current group'),
            'help' => t('Posts in current group.'),
            'operator' => 'views_handler_operator_eqneq',
            'list' => 'views_handler_filter_groupcurrent',
            'list-type' => 'select',
            'handler' => 'og_user_roles_handler_filter',
          ),
        ),
      );

Also added og_user_roles_filter_role() which will only list roles that are allowed in OGUR settings.

Also added og_user_roles_handler_filter() which will match og_users_roles.gid to current group gid.

Will be released in 3.3.
