accept post data from form, process, then redirect data to another script

[gnznroses]

I thought this would be fairly easy, but upon sitting down to do it, now I dunno.
i have an html file with a form, and this POSTs data to a PHP script. it's actually a signup form. i want to add another input box to the signup form to get extra info, but the catch is that the PHP file that process the form is encrypted and i can't edit it. so, my idea was: change the html of the form to submit to myform.php, then i'll process the new data field, and re-POST the form to the original file, "encoded.php".
except i'm not sure how to do that or if it's possible... i could use curl of course, but the user needs to be kept down this path of
user fills form -> i process the data -> original php file processes it, checks for invalid info, etc -> user lands on post-signup page, whether it was a success or it's now telling them what info needs corrected.

suggestions?

I'm doing this off the top of my head but it's something like this:

while (list($key, $value) = each($HTTP_POST_VARS)) {
$get_url .= $key . '=' . $value . '&';
}
header ("Location: encryptedpage.php?" . $get_url);

will a script that is coded to process POST variables recognize GET variables?
i wouldn't think so.

You're right, I was not thinking.

If you don't want to use curl you could

construct a form and use javascript to push the submit button
or use javascript and http library http://www.phpbuilder.com/columns/jo...l20070730.php3

hmm, i'm thinking the best solution may be:
user clicks submit button, it calls a javascript function that first does an ajax call to a script that saves the value of the new form option, then it "clicks" the submit button which goes to the original url as normal.
