redirect with post data

slam

I am using <? header ('Location: http://www.x.com/next.php'); ?>
to redirect but the post data isn't visible at the redirected page
how do I send along the post data.

you have a few choices:

you can tack the POST data onto the URL as GET variables
if the redirect is to another URL on the same physical server then you can stick the POST data into a session and retrieve on the other side
you can stick the POST data into a database that is mutually accessable from both URL's and pull it back out on the other side.
you can mimic POST submissions via this technique.

I am sending the data with Get right now but its visible so I want to eliminate that
session... I may look at that idea
I am using mysql so I could create a static table. 1 row that contains the post info . good idea
I'll look at that too.
Thanks for the suggestions

The reason the redirected page has no POST data is because that is to not automatically sent along with a redirection. You will have to "re-post" it to the redirected page. I think the correct status for this type of activity is 303.

This should help or at least give you somewhere to start. I have not tested, but I think it should be ok:

function redirect_post($url) {
	$url = str_replace('&amp;', '&', $url);

$post_string = '';

foreach ($_POST as $key => $value) {
	if (!empty($post_string)) {
		$post_string .= '&';
	}

	$post_string .= $key . '=' . urlencode($value);
}

header('HTTP/1.1 303 See Other');
header('Content-Type: application/x-www-form-urlencoded');
header('Content-Length: ' . strlen($post_string));
header($post_string);		
header('Location: ' . $url);
exit;
}

well silly me, that won't work. POST data doesn't go in the header, and I'm not sure how to send a message body along with a "Location" header (I don't believe you can).

If you're wanting to re-post to a page on the same site, then placing the data into the session will be your best bet. For re-posting to a remote site, then CURL or Sockets would be the way there.

Another possible way would be to write to the users browser a form with the data as hidden fields that submits itself to the url you want to redirect to on page load. But this is not so elegant, and relies on the client having javascript capabilities.
