When you access /foo, the server will redirect the client to /foo/ (because 
it is a directory). At the redirected page, the post data will not be sent 
again by the browser thus there are no _POST values.

Try using action="/foo/". That may work.

Subject:  PHP form POST question

I just narrowed something down about forms and POST and would like 
education. In the following scenarios, all work except #4. $_POST is null. 
Why is that?

Setup:
1) Running on localhost
2) /foo/index.php has the following:
   <? var_dump($_POST); var_dump($_GET); ?>
3) /index.php contends vary per scenario (below)

Running RHEL 3, all updates (PHP 4.3.2).

SCENARIO 1:
/index.php contains the following:

<form method="get" action="/foo/index.php">
<input name="foobutton" type="submit">
</form>

In this case in /foo/index.php $_GET has the right value, i.e.
array('foobutton' => '');

SCENARIO 2:
/index.php contains the following:

<form method="get" action="/foo">
<input name="foobutton" type="submit">
</form>

In this case in /foo/index.php $_GET has the right value, i.e.
array('foobutton' => '');

SCENARIO 3:
/index.php contains the following:

<form method="post" action="/foo/index.php">
<input name="foobutton" type="submit">
</form>

In this case in /foo/index.php $_POST has the right value, i.e.
array('foobutton' => '');

SCENARIO 4:
/index.php contains the following:

<form method="post" action="/foo">
<input name="foobutton" type="submit">
</form>

In this case in /foo/index.php $_POST is NULL.

HUH? Why is $_POST empty? Is Apache doing something to kill the form's 
post information when it has to resolve /foo to /foo/index.php?
