Redirecting with POST content

[David E. Smith]

I want to redirect input from one page to another, but it's POST content.
If it were GET, I could just do something like:
header("Locatio n: /new/form.php?a=1&b= 2")

I can't rewrite the destination script, because it's proprietary. And
compiled. And for Windows.

A few details might help: I'm using Imail's Web-based email interface on
one site, and the only form inputs available to it are username and
password. The existing form looks like this:

<FORM ACTION="http://dom.ain:8383/login.cgi" METHOD="POST">
<INPUT TYPE="hidden" NAME="page" VALUE="login">
Username: <INPUT TYPE="text" NAME="userid">
Password: <INPUT TYPE="password" NAME="passwd">
<INPUT TYPE="SUBMIT" VALUE="Login">

(Obviously, I've stripped out some of the extraneous HTML markup.)

What I'd like to do is:

* Modify that form so that it POSTs to some hypothetical "login.php" page
* Add an INPUT TYPE="CHECKBOX" NAME="SSL" CHECKED

And have this hypothetical login.php act on the SSL variable, like this
pseudocode:

if((isset($_POS T["SSL"])) && ($_POST["SSL"] == TRUE)) {
redirect (https://dom.ain:8384/);
}
redirect (http://dom.ain:8383);

Where redirect() is some fictitious function that would have to handle
the other two POSTed variables.

Again, if the destination form accepted GET, this would be trivial. It'd
just be a matter of constructing a destination URL and sending a
Location: header.

But I'm not sure how to put all this together with POST, or if it's even
possible.

So, is it possible? Any pointers? I googled this, and found a number of
people asking basically this question, but no good answers.

Thanks!

PHP can POST the data to wherever you want (among other options with
CURL [ http://www.php.net/curl ]), but that is POSTing by the server,
not the client. If you want the client to do that, it might be possible
to achieve with JavaScript.

Once the server POSTs the data and receives some feedback, you can send
that feedback to the user.


So you send a form to the client that posts to your server.
Your server (re)posts that data (possible changed/augmented) to another
script and gets the result page.
This result page is then sent to your client who is yet waiting for an
answer for her POST to your server.

Makes sense?

You'll have seen this, but I'm posting it for others' sake:

Re: Redirecting with POST content

Use Javascript, recreate the form on a blank page with all value filled
using php. then use the js function :
document.formna me.submit() at the end of the page, the form is now
automatically submitted when the page is loaded.
