Hi! I just hacked together a PhpWiki site using the latest nightly PhpWiki tar package and Apache 2.0.40 with PHP 4.2.3 provided by Mandrake 9.0. In the process I stumbled into something I think must be a bug. But first, the setup: PhpWiki resides in /phpwiki (relative to docroot). I tried to make the PATH_INFO stuff to work as described in index.php and PhpWiki Wiki pages, by making /wiki and putting the following lines to .htaccess: Action x-phpwiki-page /phpwiki/index.php SetHandler x-phpwiki-page DirectoryIndex /phpwiki/index.php Instead of a working Wiki I got 404's. Clearly, the handler delegation didn't work with Apache 2.0. After a huge amount of trials and errors I ended up with a seemingly working setup: /wiki/.htaccess: --clip-- DirectoryIndex /phpwiki/index.php RewriteEngine On RewriteBase /wiki/ RewriteRule ^(.+)$ /phpwiki/index.php/1ドル [QSA] --clip-- also, a following line has to be added to /phpwiki/.htaccess: AcceptPathInfo on With these settings, the Home Page loaded correctly. The problem was, I only got the Home Page, no matter where I went. Now, after another huge amount of trials and errors, I narrowed the problem down to PATH_INFO_PREFIX setting. The variables are set as follows: _SERVER["REQUEST_URI"] /wiki/AddingPages _SERVER["SCRIPT_NAME"] /phpwiki/index.php _SERVER["PATH_INFO"] /AddingPages _SERVER["PATH_TRANSLATED"] /var/www/mairas.net/html/AddingPages _SERVER["PHP_SELF"] /phpwiki/index.php/AddingPages However, PhpWiki assumes that PATH_INFO has the VIRTUAL_PATH (in this case '/wiki') as prefix. As can be noted, that isn't the case. I found out the following patch fixes the problem for me (TM): --clip----clip----clip----clip----clip----clip----clip----clip----clip-- --- /tmp/phpwiki/lib/config.php 2002年09月27日 16:40:34.000000000 +0300 +++ lib/config.php 2002年10月31日 22:09:29.000000000 +0200 @@ -336,7 +336,13 @@ if (VIRTUAL_PATH != SCRIPT_NAME) { // Apache action handlers are used. - define('PATH_INFO_PREFIX', VIRTUAL_PATH .

Please consider applying it to the CVS. Best regards, Matti Airas

Doh. Of course that patch gives a warning when accessing the main page
(as PATH_INFO does not exist in that case). I'm open to suggestions, how
to fix this more cleanly. :-)

OK, the settings below seem to be minimum settings with which I can get it to work. It's notable that the comment in index.php suggests that USE_PATH_INFO is by default true. Well, this is not quite true. :-) /.htaccess: <Files wiki> AcceptPathInfo on ForceType application/x-httpd-php </Files> /phpwiki/index.php: $include_path = '.:phpwiki'; if (!defined('PHPWIKI_DIR')) define('PHPWIKI_DIR','/var/www/mairas.net/html/phpwiki'); if (!defined('USE_PATH_INFO')) define('USE_PATH_INFO', true); m.

If you don't explicitly set USE_PATH_INFO, then it's value is
auto-determined by the following code (in lib/config.php):
if (php_sapi_name() == 'apache')
define('USE_PATH_INFO', true);
else
define('USE_PATH_INFO', ereg('\.(php3?|cgi)$', $SCRIPT_NAME));
I don't currently have access to a machine running Apache 2.0. (And
I don't want to install it right now...)
In order that we can try to fix the auto-detection:
Can you tell me what php_sapi_name() returns on your system.
Apparently, it's something other than 'apache'.
Also, is there way one can tell (from PHP) whether AcceptPathInfo
is on or not? I assume if (defined($_SERVER['PATH_INFO'])) then
AcceptPathInfo is enabled, but I don't think the converse is true.
(If the URL does not contain any trailing path info, then (at least
in Apache 1.3.x, PATH_INFO is undefined (not just empty).)

If AcceptPathInfo is on, PATH_INFO behaves exactly as in Apache 1.x, i.e. it may either be undefined or defined, depending on the actual path. Unfortunately I have no idea whether the value of AcceptPathInfo can be deduced from within PHP. Maybe someone with more experience on PHP can answer that? However, since the preferred installation method (as described in http://phpwiki.sourceforge.net/phpwiki/PrettyWiki) requires modifying the top-level .htaccess or the server configuration, IMHO it would be simpler to just provide a sample top-level .htaccess like follows: <IfDefine APACHE2> AcceptPathInfo on ForceType application/x-httpd-php </IfDefine> <IfDefine !APACHE2> SetHandler application/x-httpd-php </IfDefine> Hmm... Of course, AcceptPathInfo setting should still be detected somehow, or else it might be difficult to get PhpWiki to work reliably out-of-the-box... Suggestions for workarounds? Cheers, m.
Thanks for the info, Matti. It turns out that ForceType (instead of SetHandler) works with (at least my) Apache 1.3.x. If updated http://phpwiki.sourceforge.net/phpwiki/PrettyWiki, take a look and make any appropriate changes... I see no point of fixing config.php so that it turns on USE_PATH_INFO by default under apache 2.0, since it seems that default installations of 2.0 don't support PATH_INFO... If someone can figure out a way to determine whether AcceptPathInfo is enabled or not, that would be different. At this point, I think I'll just put a pointer to PrettyWiki in the index.php comments...
