Description:
------------
$_POST variables aren't accessible from within a 
multiview if one configures the action of a form to be 
the child of a multiview.

In other words, If I set the action of a form to be 
'example.com/multi/sub' where multi is a PHP file 
called multi.php that catches the url 'example.com/
multi/sub/' (by using apache's multiviews), multi.php 
will not have access to the $_POST variable.

It works if one sets the action as 'example.com/multi/
'.

Reproduce code:
---------------
Example code:

<form method="post" 
 action="http://example.com/multi/sub/" 
 name="form">

     <input 
     type="submit" 
     name="submit" 
     value="Value" />   
</form>


multi.php:

echo $_POST['submit']

Expected result:
----------------
Expected:

$_POST['submit'] == "Value"

Actual result:
--------------
Blank. I think PHP associates the $_POST variable with 
/multi/sub when sub isn't a script/file. Instead the 
request is handled by multi.

Apache version, how to configure httpd.conf, how PHP is configured (module/cgi), etc.
 [2004-02-25 21:31 UTC] vanlei at yahoo dot com 
Apache: Server version: Apache/1.3.29 (Darwin)

httpd.conf:

Inside the config for the site, you need to add:

<Directory "/site/to/www">
        Options MultiViews
</Directory>

PHP is configured as an apache mod. Version 4.3.4

You should perhaps reread the Apache documentation. As far as I understand it, Multiviews are used for automatic language selection and aren't involved in your problem.

I've run some tests with http://my-server/script.php/morestuff/ using GET and POST requests.

Linux, Apache 2, PHP 4.3.4 module: works
Windows, Apache 2, PHP 4.3.4 module: works
Windows, Apache 2, PHP 4.3.4 CGI: doesn't work (maybe misconfiguration)

And it works even with MultiViews disabled.

Although I haven't tested Apache 1, I don't think there is a PHP problem.

Try if a normal GET request works on such URLs, and if it doesn't, it might be a problem with your apache configuration.

I traced the problem a little better. I wasn't coming 
in through the overriden php file, but through 
ErrorDocument. Now I'm not sure if it is a bug or not, 
but ErrorDocument doesn't see POST. In any case I 
solved it in a more elegant way, but I'll leave this 
here for comment. Should ErrorDocument receive POST 
requests?

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

The POST & GET data does not get passed to the 
ErrorDocument handler, only the missing URL is.
