How to redirect a webpage request while keeping all POST variables to another PHP page

March 22, 2007 9:01 AM

Is there an easy way in PHP to send all the POST variables submitted in a form to another webpage?

I am currently using the PayPal API for some shopping cart/order management things I've custom written. For a short period of time, I need to use two different IPN scripts. The way the IPN for PayPal works is that data is sent from PayPal to a PHP script on my website with a number of POST variables. I would like to send that same page request (with the post variables in tact) to another PHP script/page. Is there an easy way to redirect the web page request PayPal sends to another web page, with all the POST variables in tact after it has been received on my site?

Is there some straightforward way to do this?

Yeah, use curl to post to another page.

Something like this should work:

$url = "/path/to/new/page.php";
$params = "$username_field_id=$username&$password_field_id=$password"; // put whatever variables you need here. you can read them in from your last page by doing $variable=$_POST['variable_name']
$user_agent = "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)";

$connection = curl_init();
curl_setopt($connection, CURLOPT_POST,1);
curl_setopt($connection, CURLOPT_POSTFIELDS,$params);
curl_setopt($connection, CURLOPT_URL,$url);
curl_setopt($connection, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($connection, CURLOPT_USERAGENT, $user_agent);
curl_setopt($connection, CURLOPT_RETURNTRANSFER,1);
curl_setopt($connection, CURLOPT_VERBOSE, 1); //for debugging purposes
curl_setopt($connection, CURLOPT_SSL_VERIFYPEER, FALSE); // this line makes it work under https

$result=curl_exec ($connection);
echo("Results: ".$result); // debugging purposes

Best answer: Can't you just 301 redirect?

Response by poster: 301 redirect worked like a charm.

Just saved me a bunch of hassle. Thanks!

Well, sure, if you want simplicity you could use a 301... :)
