Is it possible to use PHP for redirecting an encrypted PayPal button code?

I realize this thread is a little old, but I thought I'd contribute the code to do this if anyone else need it...

I see two solutions. One in the JavaScript solution outlined above (have JavaScript click the button for the user):

SOLUTON 1: JavaScript

(This is a hybrid php / JavaScript / HTML solution... just remove the php if you want):

echo '<form action="https://www.paypal.com/cgi-bin/webscr" method="post" id=paymentform>';
echo '<input type="hidden" name="cmd" value="_s-xclick">';
echo '<input type="image" src="https://www.paypal.com/en_US/i/btn/x-click-but23.gif" border="0" name="submit" alt="Make payments with PayPal - it\'s fast, free and secure!">';
echo '<input type="hidden" name="encrypted" value="';
echo $paypal->getButton();
echo '">';
echo "</form>\n";
?>

<script language=javascript>
setTimeout('redir()', 10000);
function redir(){
document.getElementById('paymentform').submit();
}
</script>

---------
Just make sure the id of the form is the one called by JavaScript, and you'll be sweet.


SOLUTION 2: Pure php
<?php
$data['custom reason'] =

$data['return'])) $return ="http://yoursite.com/thanks.php";
$data['cancel_return'])) "http://yoursite.com/cancelled.php";
$data['notify_url'])) = "http://yoursite.com/ipn_res.php";
// and so on with any info you want to send to PayPal, anything you would put in the form
// Then, simply:
$result = post_it($data, "https://www.paypal.com/cgi-bin/webscr");

// Now, we've "faked" posting the data to PayPal.
// We need to analyze the $result and see where to send the user next
// (that is left as an exercise for the reader ;-)
?>


<?php

function post_it($datastream, $url) {
$url = preg_replace("@^http://@i", "", $url);
$host = substr($url, 0, strpos($url, "/"));
$uri = strstr($url, "/");
$reqbody = "";
foreach($datastream as $key=>$val) {
if (!($reqbody=='')) $reqbody.= "&";
$reqbody.= $key."=".urlencode($val);
}
$contentlength = strlen($reqbody);
$reqheader = "POST $uri HTTP/1.1\r\n".
"Host: $host\n". "User-Agent: PostIt\r\n".
"Content-Type: application/x-www-form-urlencoded\r\n".
"Content-Length: $contentlength\r\n\r\n".
"$reqbody\r\n";
$socket = fsockopen($host, 80, $errno, $errstr);

if (!$socket) {
$result["errno"] = $errno;
$result["errstr"] = $errstr;
return $result;
}

fputs($socket, $reqheader);

while (!feof($socket)) {
$result[] = fgets($socket, 4096);
}

fclose($socket);

return $result;

}

?>
