Неопределенный индекс: GROUP_NAME_TAKEN

Question

Я скопировал функцию из phpBB, чтобы я мог внести небольшие корректировки в возвращаемый объект. Он отлично работает, создает группа возвращает идентификатор группы и т.д. Единственная проблема в том, когда он выходит из строя (в случае, название группы существует) я получаю следующее сообщение об ошибке:

[phpBB Debug] PHP Notice: in file C:/.../phpbb_library.php on line 586: Undefined index: GROUP_NAME_TAKEN

Вот мой код.

Constructor:

     global $phpbb_root_path, $phpEx, $user, $auth, $cache, $db, $config, $template, $table_prefix; 

     define('IN_PHPBB', TRUE); 
     define('FORUM_ROOT_PATH', Kohana::$config->load('global.FORUM_ABSOLUTE_PATH')); 

     $phpbb_root_path = (defined('PHPBB_ROOT_PATH')) ? PHPBB_ROOT_PATH : FORUM_ROOT_PATH; 
     $phpEx = substr(strrchr(__FILE__, '.'), 1); 

     // Include needed files 
     include($phpbb_root_path . 'common.' . $phpEx); 
     include($phpbb_root_path . 'config.' . $phpEx);

     $auth->acl($user->data); 
     $user->setup();

     $this->_user = $user;

Ошибка я получаю исходит от этой линии: $error[] = $user->lang[$err];

Answer 1

Похоже, что вы просто не хватает языка определение для GROUP_NAME_TAKEN.

Например, в (или на каком бы языке файла) язык/EN/ACP/groups.php

'GROUP_NAME_TAKEN'   => 'The group name you entered is already in use, please select an alternative.', 

Edit: попробуйте это включить файл группы языков:

$user->add_lang('acp/groups'); 

Добавить его в ваш конструктор сразу после линии global (так что существует $user).
