在BuddyPress中为特定用户角色启用组创建

Question

BuddyPress提供了“bp_user_can_create_groups”过滤器来限制用户创建组的能力。参考 - http://wordpress.org/support/topic/restrictallow-group-creation-by-user-role?replies=3#post-4617184 和 http://etivite.com/api-hooks/buddypress/trigger/apply_filters/bp_user_can_create_groups/

如何使用此过滤器来限制在BuddyPress的特定用户角色组创建？目前，只有管理员被允许创建组，我也不想让每个用户都能够创建组。

我加入以下代码，以BP-custom.php但它不工作

function create_groups1($can_create, $restricted=false) { 
// maybe we don't want to override if it's restricted? 
if (! $restricted){ 
    // get the logged in user's ID 
    $user_ID = get_current_user_id(); 
    // some logic to determine if the current user can create a group 
    $user1 = new WP_User($user_ID); 

    if (!empty($user1->roles) && is_array($user1->roles)) { 
      $r=$user1->roles[0]; 
    } 
    if (current_user_can('read')) { 
     $r="subscriber"; 
    } 
    if ($r == "subscriber" || $r == "participant"){ 
     // we will return this allowing them to create groups 
     $can_create = true; 
    } 
} 
return $can_create; 
} 
add_filter('bp_user_can_create_groups', 'create_groups1', 10, 2);

你需要编写一个函数，它连接到“bp_user_can_create_groups”挂钩。在您的功能内部，确定您是否希望当前用户能够创建组并相应地返回$can_create。

function bp_user_can_create_groups($can_create, $restricted=false){ 
    // maybe we don't want to override if it's restricted? 
    if (! $restricted){ 
     // get the logged in user's ID 
     $user_ID = get_current_user_id(); 
     // some logic to determine if the current user can create a group 
     if (user_can_create_group($user_ID)){ 
      // we will return this allowing them to create groups 
      $can_create = true; 
     } 
    } 
    return $can_create; 
} 
add_filter('bp_user_can_create_groups', 'bp_user_can_create_groups', 10, 2);
