I am trying to find a way to redirect a user while keeping the POST header vars in tact.

Here is the situation: I have a user submit a form that posts name, email and feedback comments. I want to submit this to a php page and capture the user-submitted data, no-problem there. After I capture the data, I have to redirect the user to an outside marketing vendor that submits users name and email to a newsletter signup, and in return they are redirected back to us landing on a thank-you page.

I have to redirect the user using POST data from the users IP (spam protection), but I can't accept the feedback in the GET data because of the size limits.

Any suggestions on how to accomplish this???

Hidden Fields.

The fields that the 3rd party is requestiong pass them trough your pages and when ready to redirect take the Data off your hidden fields

what size limits? if its a file you can create a temp directory to put the file and send a pointer instead?

I don't really understand what you mean. The 3rd party we're using is AWebber.com. What our form takes is users name, email and feedback comments. AWebber just needs the name and email to sign them up in our newsletter, and I need all three to record thier comments and mail them a discount coupon. There is other information I need to pass to AWebber, but it is static account info.

The "size" I'm referring to is that the comments string may overexceed the char limit if I were to have AWebber redirect back to us passing the string in the url as a GET var.

It just sounds like you need temporary storage, so why not create a temp file for the information.

Sessions is probably the proper way for dealing with this though.

The thing is, do you have to redirect the user to the outside or have you got the information and can just pass it directly to them to be processed without user intervention, so that you avoid redirection.

Unfortunately, I have to have the user physically go to AWebber with the post vars so that AWebber can signup user to our newsletter, and then they are redirected back to our site of a page of our choice. The process is invisable to the user, but it helps AWebber prevent spamming and bots to abuse the system.

I do not think it is possible to get a browser to send POST variables through PHP and header.

I think you may have to use a form as kIDJOE says, just put everything in hidden form fields with a form that posts to the site. You can use Javascript for instant submit, but place a 'Continue' button as a fallback:

Code:

<form action="http://www.thesite.com/script/" method="post" name="theform">
<input type="hidden" name="email" value="<?php echo $email; ?>" />
<!-- etc -->
<input type="submit" value="Continue" />
</form>
<script type="text/javascript">document.theform.submit();</script>

I would suggest using PHP to make the request using sockets, but you say it needs to come from the same IP so thats out...

i think theres actually a way to do it, theres a library called cURL (PHP: CURL, Client URL Library Functions - Manual) that might be able to do just that. i was in the same predicament as you, but i was able to work around it without using cURL. the library might take a bit of time to set up, and i dont think its compatible with all web installations. worth a shot though.
