phpBB3(の認証)との連携

特徴

  • phpBB の認証システムを用いるので、phpBB にログインしていればDokuWikiに再ログインする必要ありません(逆も同様)。もちろんログアウトも同じです。
  • Using phpBB's groups for DokuWiki's access control list. Some default groups are already implemented (even if they are not displayed on DokuWiki's configuration page):
    • REGISTERED: default group (replaces group user)
    • ADMINISTRATORS: administrator/super user (replaces group admin)
    • GLOBAL_MODERATORS: managers
  • 日付フォーマットとタイムゾーンを同期します。

失われる機能

  • ユーザ登録
  • フルネームの表示(phpBBがデフォルトでユーザプロフィールにフルネームの情報を持っていません。代わりにユーザ名が表示されます。)
  • メディアマネージャとの連携。Wikiで画像が全く表示されない。(パスの問題?)1)
  • Language support

インストール手順

これを適用するには、DokuWiki 2007-06-26b用のパッケージをダウンロードするか次のステップに従って下さい。

  1. inc/auth/phpbb3.class.php を作成
  2. inc/init.php を編集
  3. inc/utf8.php を編集
  4. inc/cache.php を編集
  5. 変数をセットする

Note that it does not function any more after the merge of the requireall branch on 2010-03-12.

inc/auth/phpbb3.class.php を作成

inc/auth/ ディレクトリに phpbb3.class.php というファイル名で次の内容のファイルを作成して下さい。 (エラーが発生するようであれば、コメントセクションにあるように修正して下さい。)

phpbb3.class.php

inc/init.php を編集

inc/init.php ファイルから次の行を探して下さい。

$_REQUEST = array_merge($_GET,$_POST);

それをコメントアウトするために行頭に//を追加して下さい。

//$_REQUEST = array_merge($_GET,$_POST);

これは、phpBBが$_REQUESTをクッキーで使用するためです。

inc/utf8.php を編集

inc/utf8.phpにはすでにphpBBによって定義された次の関数があります。

  • utf8_strlen
  • utf8_substr
  • utf8_strtolower
  • utf8_strtoupper
  • utf8_ucfirst
  • utf8_strpos

なので、これらの関数の前後に

if(!defined('IN_PHPBB')) { ... }

を追加し、phpBBを使わなくなった時にDokuWikiがこれらの関数を定義するようにしましょう。

例: utf8_strlen

変更前:

function utf8_strlen($string){
  return strlen(utf8_decode($string));
}

変更後:

if(!defined('IN_PHPBB')){
	function utf8_strlen($string){
	  return strlen(utf8_decode($string));
	}
}

inc/cache.php を編集

最後の問題は、DokuWiki と phpBB が同じcacheクラスを持っている事です。そこで、DokuWikiのクラスの名前を変更します。inc/cache.php ファイルの中で次の行を探して下さい。

class cache {

そして、次のように変更して下さい。:

class wiki_cache {

変更前:

function cache($key,$ext) {

変更後:

function wiki_cache($key,$ext) {

変更前:

class cache_parser extends cache {

変更後:

class cache_parser extends wiki_cache {

変更前:

parent::cache($file.$_SERVER['HTTP_HOST'].$_SERVER['SERVER_PORT'],'.'.$mode);

変更後:

parent::wiki_cache($file.$_SERVER['HTTP_HOST'].$_SERVER['SERVER_PORT'],'.'.$mode);

feed.php を編集

cacheクラスの名前を変更した(上記参照)ので、このクラスが呼び出される feed.php でも、RSS/Atom フィードが生成されるように名前を変更しましょう。

変更前:

$cache = new cache($key, '.feed');

変更後:

$cache = new wiki_cache($key, '.feed');

もしこれを変更しないと “XML Parsing Error” が発生します。

inc/common.php を編集

phpBBとDokuWikiの日付フォーマットとタイムゾーンを同期するため、inc/common.php ファイルの dformat() 関数を変更しましょう。(コメントセクションにあるように、この修正を行うと逆にエラーが発生する可能性があります。)

変更前:

function dformat($dt=null,$format=''){
  global $conf;
 
  if(is_null($dt)) $dt = time();
  $dt = (int) $dt;
  if(!$format) $format = $conf['dformat'];
 
  $format = str_replace('%f',datetime_h($dt),$format);
  return strftime($format,$dt);
}

変更後:

function dformat($dt=null){
  global $user;
 
  if(is_null($dt)) $dt = time();
  $dt = (int) $dt;
 
  return $user->format_date($dt);
}

DokuWikiはphpBB3の日付設定を使用します。

変数をセットする

最後にすることは、今までの変更を適用することです。conf/local.protected.php ファイルはDokuWikiが操作しないので最も良い場所です。もしこのファイルがない場合は、新たに作成して下さい。そして、ファイルに次の記述を追加して下さい。

<?php
/*
 * phpBB3
 */
 
define('IN_PHPBB', true);
$phpbb_root_path = 'phpBB3/';
$conf['authtype'] = 'phpbb3';
?>

$phpbb_root_path はDokuWikiのディレクトリから見たphpBBの相対パスです。例えば、DokuWikiを“var/user/dokuwiki“に、phpBBを”var/user/forum/“というように、phpBBをDokuWikiと同じ階層にインストールしたのであれば、$php_root_path../forum/というようにしなければいけません。

I did this, but it wouldn't authenticate me. I tried pasting it in local.php, and it worked just fine. Is there a step missing?

phpBB3の設定

cookieの設定

上で行った変更がうまく動くようにするためには、phpBB3のACP (admin control panel)でのcookieを正しく設定することが重要です。例えば、cookieの設定が間違っていると、まずphpBB3にログインし、あるページをロードするとDokuWikiから強制的にログアウトさせられます。

もし、phpBB3を”www.yourdomain.com/phpBB3/“に、DokuWikiを”www.yourdomain.com/dokuwiki/“にインストールしている場合は、phpBB3のACPで“cookie 設定”の“cookie パス”を”/phpBB3/“と設定してはいけません。正しくは、“cookie パス”には”/“と設定して下さい。 carstenfuchs [at] t [dash] online [dot] de

セキュリティ設定

phpBB3のACPで他にチェックすることは、セキュリティ設定の“リファラ設定”です。もし、この設定が“ホストとスクリプトパス”になっていると、上記の間違ったcookieパスの設定のように、うまく動作しません。このため、“リファラ設定”では“ホストとスクリプトパス”または“なし”を選択して下さい。

  • Integration with Mediamanager, pictures are not shown in the wiki anymore (pathproblem?) I just followed these instructions and I got no problem with Mediamanager, using DokuWiki 2009-02-14 and phpBB3 3.0.4, all works fine :-) and by the way, thanks for this page!
  • it doesn't work well for me. contents of conf/local.protected.php appears on site. like this http://gimp.kr/wiki/ I use phpbb3.0 gold and DokuWiki 2007-06-26b on centos5 and MySQL. what do I miss?
    • Make sure their isn't spaces or characters before <?php in your local.protected.php file.
  • Be careful if you are using this on your local testsite: it is REQUIRED that you are using a password in accessing your database, otherwise the mysql_auth class will throw errors!
  • What did I do wrong here? DokuWiki is located at http://test.iphexx.net/dokuwiki . I did everything as described above…
  • Do these instructions only work for DokuWiki 2007-06-26b? I'm trying, with no success to use it with 2008-05-05. I get an error “Fatal error: Call to undefined function utf8_strtolower() in /hsphere/local/home/eriebuoy/forums.pygmyisland.net/dokuwiki/inc/pageutils.php on line 108” Installation is in /dokuwiki and phpBB3 is in /phpBB3 on same subdomain at forums.pygmyisland.net – anyone give me some hints of what I've done wrong? I did perform all of the instructions above including the edit of the utf8.php file.
  • hi! I've followed all steps and it work but if I go in Administration → Access Control List Management it send me this error
Warning: require_once(../phpBB3/common.php) [function.require-once]: failed to open stream: No such file or directory in C:\www\DokuWiki-2008-05-05\inc\auth\phpbb3.class.php on line 18

I have a forum in: C:\www\phpBB3\ and DokuWiki in C:\www\dokuwiki-2008-05-05\ so I have this config file:

<?php
/*
 * phpBB3
 */
 
define('IN_PHPBB', true);
$phpbb_root_path = '../phpBB3/';
$conf['authtype'] = 'phpbb3';
?>
  • It's because this line in phpbb3.class.php doesn't really work. /lib/exe doesn't get a match on my server, and the depth it must go down is variable.
if(strpos($_SERVER['PHP_SELF'], "/lib/exe/") !== false) { $phpbb_root_path = '../../'.$phpbb_root_path; }
  • You can solve it adding this line before (it could be coded better. I am just too busy at the moment):
if(strpos($_SERVER['PHP_SELF'], "/lib/plugins/") !== false) { $phpbb_root_path = '../../../'.$phpbb_root_path; }
if(strpos($_SERVER['PHP_SELF'], "/lib/exe/") !== false) { $phpbb_root_path = '../../'.$phpbb_root_path; }

  • Hi, I've been using DokuWiki with PunBB before and the bridge worked quite well. Now I installed phpBB3, a new version of DokuWiki and this integration mod. If I click on the wiki link in the forum portal all I get is a blank page, no errors or unwanted display, just a blank page. Even the source view of the page is blank.
  • I just want to say that I'm not using DokuWiki anymore, so I'm not using this mod anymore, too, of course and so I can't help anyone with problems regarding DokuWiki and phpbb3. — Markus -voks- Henn 2008/10/16 10:34
  • Just a few words for integrating authentication with phpBB 3.0.4:
There were only a few errors I run into. All the functions mentioned below utf8.php (utf8_strlen, utf8_substr, utf8_strtolower, utf8_strtoupper, utf8_strpos) have to be excluded from being defined in DokuWiki, not only that one which is declared in this example. Same way to exclude with if(!defined('IN_PHPBB')). The last one I found was the name of the standard user group which has been changed since phpBB2 from “user” to “registered user”. I was updating my existing config from 2 to 3 and any other settings except that ones mentioned above could remain unchanged. gonzo99/27.02.2009
  • lonney@gmail.com 09/04/01 After doing all these mods: Parse error: syntax error, unexpected '}' in /home/../web/wiki/inc/utf8.php on line 248
  • nammyung 2009/10/31: If the paths are not resolving properly, just replace them with absolute path to the phpbb3 install. For example, $php_root_path='/var/www/html/forum/'; If you do this, you can just comment out the two “if(strpos($_SERVER['PHP_SELF']” lines.

Cant you just make DokuWiki PLUG into the MySQL auth part of phpbb3? so what if you have to login twice!@

Worked fine for me (please note the phpbb cookies value and my subdomains) :

  • 2010 Jan 06 - I have two subdomains on a Mandriva server : a restricted access DokuWiki Release 2009-12-25 Lemming at wiki.xxx.org (in /dokuwiki) and phpBB 3.0.6 at forum.xxx.org (in /phpbb). The instructions work perfectly after setting $phpbb_root_path = '../phpbb/' in conf/local.protected.php, and after setting the cookies domain in the phpbb admin panel to '.xxx.org' : I can login in phpBB and use the wiki, I see the phpBB users list in DokuWiki, etc.

Problem:

  • 2010 jan 07:

I have phpBB 3.0.6 and i used the latest 5 versions of DokuWiki. Then i used this tutorial here, did everything 10 times but with no success. The forum is at: http://192.168.69.87:4001/forum2/forum/ The wiki is at : http://192.168.69.87:4001/forum2/wiki/ – Settings in the phpBB-forums for cookies are: Cookie-Domain: http://192.168.69.87:4001/forum2/forum/ – and – Cookie-Path: / – Do we need to edit the “mysql.conf.php” file ? Because i get the error: “User authentication is temporarily unavailable. If this situation persists, please inform your Wiki Admin.” – Thanks for HELP ! FIXME

  • 2010 May 10: RSS/Atom issue fixed. Refer to “Edit feed.php” above in this page to view fix.

Problem:

  • 2010 July 1: I installed this plug in manually and everything works great however I believe I am having a problem with the date because I am getting this error where the date should be displayed:
[phpBB Debug] PHP Notice: in file /includes/session.php on line 2167: strtr() [function.strtr]: The second argument is not an array

When I check that line of code for errors this is what the code is:

return strtr(@gmdate($date_cache[$format]['format_long'], $gmepoch + $zone_offset), $date_cache[$format]['lang']);

Update - 2010 July 6th: I returned the date mod back to the original code and the error is fixed. Update2 - 2010 July 7th: The toolbar does NOT work and it just gives me a link to “Media Files”! I've tried all of the troubleshooting tips offered here and nothing fixes it. Any help?! Update3 - 2010 July7th: Make sure the permissions of the dokuwiki/lib/exe/js.php file are set to 755 otherwise the toolbar will not work!

  • I had some problems getting this integration to work, it would not authenticate. But, I found the problem: If $_SERVER['PHP_AUTH_USER'] is set on your server, it will try to log in with that. If you have that problem, you can either unset it, or remove the corresponding code in inc/auth.php
  • 私は、DokuWikiの最新バージョン(Anteater)でこれを解決する方法を見つけました。要するに、クラスが宣言される前にグローバル変数を宣言します。
  • phpbb3.class.php ファイルの最初にグローバル変数を追加します。
