cURL Question

[D Benfer]

Hi all,

Im a bit thrown by curl. I want to submit some order data on an ecommerce
site via a form to a php page, where the data is saved to a database.
Then I want to use curl to submit the form data I just saved (and
redirect the user) to my secure credit card gateway.

Problem is, they have their own secure payment screen where the credit
card information is entered. I can't just retrieve the variable with a
transaction success/failure setting. Plus, the curl code I use sends me
there as if I was still on my own server. No secure connection, and the
graphics on their server tries to load from mine. Looks very poor.

Anyway, here's the code:

$ch = curl_init("https://server.com/payment.url");
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postdata);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_REFERER, "http://site.com/payment.html");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 0);
curl_exec($ch);
curl_close($ch);
I guess my question is - is there an option in curl to acutally get the
browser to follow the posted data as if I clicked the button on a page?
FOLLOWLOCATION does not get me there for some reason.

All help is greatly appreciated!

Well, you just skipped the secure part anyway. From the HTML form to
your script which should redirect the connection, your connexion
wasn't secure, the data was not safe. cURL will handle the secure
connection from the script to the other form processor, but your
connection won't be secured by that.

The best you can do is get the POST response by the secure server into
a string, analyse the result and display your own page. The default
behavior of cURL is to output the ressponse direcly, you can use
output buffering to solve that problem. (ob_start() and such).

Ah, ok. So the person who referred this to me was incorrect. I was told
this would _redirect_ you to a page. It just fetches the resulting page,
eh? No wonder I searched and searched and never found an answer! Thanks
for the response!
