At a guess, you're using Apache and it's doing an internal redirect because you've
used a relative pathname (so the file must be in the same document root!); in this
case, Apache just does a silent internal substitution of the redirect page, and all
data associated with the context will remain intact -- there is no round-trip back to
your browser.
If you use an absolute URL in the Location: header, Apache will return the redirect to
your browser -- and because your browser now knows it's a genuine new request, the
POST data is not resent.
The trick is to look at the URL appearing in your browser's address bar -- if it stays
as the originally requested address, Apache did an internal redirect; if it changes to
the redirect address, it was an external redirect which round-tripped to your browser.
Cheers!

If the processing page and other.php page are two separate pages I don't
see how you could be getting the same $_POST data that the processing
page is receiving. You aren't passing any data from your processing
page to hidden form inputs (or something) on that page before you call
header() are you? Perhaps if you gave an example of your code I might
have a better idea of what is going on. You could also try using
unset($_POST) in other.php to make sure $_POST is empty for that page.

The Location header requires an absolute URL.

I think you made a typo or you're misinterpreting something. The URL
referenced in a Location header will be requested with a GET request, so
it is impossible that any POST data exists.

Re: [PHP] Header Redirect POST
Here is a url with the problem that i was describing
http://xiot.darktech.org
I fiddled and I found what the problem.
Header('Location: $calling) the first char in $calling can not be a
/
I was setting $calling with $_SERVER['PHP_SELF'] which adds the / in front
of the path.
I changed it to . . $_SERVER['PHP_SELF'] and it worked
take a look at the url to see what was going on.
Here is the code that im using
--index.php
print_r($_POST);
...
echo form action='poll.php' method='POST';
echo input name='poll_id' type='hidden' value='1\n;
echo input name='calling' type='hidden' value=' .
$_SERVER['PHP_SELF'] . '\n;
echo input name='poll_choice' type='radio' value=1Choice 1;
echo input name='poll_choice' type='radio' value=2Choice 2;
echo input name='poll_choice' type='radio' value=3Choice 3;
echo input type='submit' value='submit';
echo /form;
--poll.php
$poll_id = $_POST['poll_id'];
$poll_choice = $_POST['poll_choice'];
$calling = $_POST['calling'];
if (isset($poll_id)) {
unset($_POST);
castVote($poll_id, $poll_choice);
Header(Location: $calling);
exit();
}
