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?
