I am trying to get URL Rewrite working in Gallery2. I am using the FastCGI interface set to PHP Style and have these settings in my PHP.ini file:
cgi.force_redirect = 0
cgi.fix_pathinfo = 0

Here is the php file that tests if your server can do URL Rewrite via the PATH_INFO method:

Quote:

<?php
/**
* This is a test file for the PHP Path info Parser. Shows PASS_PATH_INFO on success or
* FAIL_PATH_INFO otherwise.
*
* Usage: index.php/test/path/info
*/

if ($_SERVER['PATH_INFO'] != $_SERVER['SCRIPT_NAME'] &&
$_SERVER['PATH_INFO'] == '/test/path/info') {
print("PASS_PATH_INFO\n");
} else {
print("FAIL_PATH_INFO\n");
}

?>


Then to test you just plug a URL like this into you browser:
hxxp://www.blablabla.com/test.php/test/path/info

$_SERVER['PATH_INFO'] should return /test/path/info
and
$_SERVER['SCRIPT_NAME'] should return /test.php

But with Abyss 2.4 it returns /test.php for both.

Is there anyway to make this work?

Ermax,

Edit the PHP interpreter declaration in Scripting Parameters and set its type to Standard (instead of PHP Type).

I have already tried changing cgi.fix_pathinfo to 1 and changing from PHP Style to standard but the test still fails.

I finally got URL Redirection working for Gallery2 using the PATH_INFO method.

Here is my recipe:

PHP 5.2.1
Abyss X1 2.4
Gallery 2.2.1

Interface: FastCGI (Local - Pipes)
Interpreter: php-cgi.exe
Type: Standard

Php.ini:
cgi.force_redirect = 0
cgi.fix_pathinfo = 1

Then do a global find and replace on your G2 install directory including sub directorys for:
Find 'PATH_INFO' and replace it with 'ORIG_PATH_INFO' (including the single quotes).

As said before PHP doesn't conform to the CGI standard properly and Gallery2 just works around this problem. So when you fix PHP with cgi.fix_pathinfo you break G2.

I noticed that with fix_pathinfo set there is a variable called ORIG_PATH_INFO that is the equivalent of PATH_INFO with fix_pathinfo not set. (well on IIS anyways)

Now that URL rewrite works I was able to get the new (in G2.2) WebDAV mount stuff working on WinXP.

Thanks Aprelium for your help. You talked me into turning fix_pathinfo back on which lead me to this ORIG_PATH_INFO variable. I still don't fully understand why PATH_INFO doesn't work with Abyss with fix_pathinfo set to 0 like it does on other servers.

I hope this helps someone. I know I have been looking for this ability for a long time. When 2.4 came out I was so excited until I realized it didn't directly read the rules in the .htaccess files that G2 creates.

Well I found another problem.

If you goto a URL like:

www.blablabla.com/phpinfo.php/test+test

PATH_INFO should return /test+test like all other servers do. Instead Abyss escapes the + with %2B. So if you have a album in gallery2 that has a space in the name the link will not work. I guess I am going to have to rig G2 some more to deal with Abyss.

I did a goolge for phpinfo.php add found a bunch of sites. It is kind of handy to test what non Abyss servers return for the PATH_INFO variable by going to these sites with exposed phpinfo.php files.

Ermax,

When aprelium said to set the PHP interpreter to standard, he was on about in the abyss web console

Actually, the %2B is what your browser requests. That's not Abyss. The browser automatically changes those "bad" URL characters into acceptable ones. In PHP, to reverse this process use this:
Code:
<?php $path_info = urldecode($path_info); ?>

well when I goto say an IIS server and request a page like, phpinfo.php/test+test, PATH_INFO returns /test+test. But when I do the same request with the same browser to an Abyss server PATH_INFO returns /test%2Btest

It realize the browser escapes the + with %2B but it looks like non Abyss servers unescape the %2B back to +.
