Paypal upload to cart, without form?

[Dragen]

Hi,

I'm trying to integrate my custom shop with paypals payment options.

What I'm trying is to use the shopping cart 'upload' facility: https://www.paypal.com/IntegrationCenter/ic_standard_home.html#individual

Unfortunately Paypal seem to have a block on using Curl or Fopen etc, by checking that the url is from Paypal.

 

To try and get around this I was looking into the Header and found this topic: http://www.pdncommunity.com/pdn/board/message?board.id=basicpayments&message.id=3393

 

I've been trying to get this to work, but instead it just tries to download a file instead. Here's the code I'm using:

<?php
$paypal = '[email protected]';
$vars = 'upload=1&cmd=_cart&business=' . $paypal . '&currency_code=GBP';

$i = 1;
foreach($_SESSION['basket']['pay_sec'][$_POST['id']]['items'] as $id => $items){
$vars .= '&item_name_' . $i . '=' . $items['name'];
$vars .= '&amount_' . $i . '=' . $items['price'];
$vars .= '&quantity_' . $i . '=' . $items['quantity'];

$i++;
}

$host = "www.paypal.com";//'www.sandbox.paypal.com';
$path = "/cgi-bin/webscr";
$vars = urlencode($vars);

header("POST " . $path . " HTTP/1.1");
header("Host: " . $host);
header("Content-Type: application/x-www-form-urlencoded");
header("Content-length: " . strlen($vars));
header("Connection: close");
header($vars);
?>

any ideas?

can anyone help me with this?

I've asked on the Paypal Developers forum, but none of the moderators (or members) seem to know or have a definite answer. None of them could even tell me if using Curl should work or not..

 

 

EDIT:

If anyone's interested in my Curl code:

<?php
$paypal = '[email protected]';
$vars = 'upload=1&cmd=_cart&business=' . $paypal . '&currency_code=GBP';

$i = 1;
foreach($_SESSION['basket']['pay_sec'][$_POST['id']]['items'] as $id => $items){
$vars .= '&item_name_' . $i . '=' . $items['name'];
$vars .= '&amount_' . $i . '=' . $items['price'];
$vars .= '&quantity_' . $i . '=' . $items['quantity'];
$i++;
}
$vars = urlencode($vars);

$ch = curl_init();
curl_setopt($ch,CURLOPT_URL, 'https://www.paypal.com/cgi-bin/webscr');
curl_setopt($ch, CURLOPT_FAILONERROR, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-type: text/html"));
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $vars);

$res = curl_exec($ch);
curl_close($ch);
if($res === false){
echo 'false';
}else{
echo 'true';
print_r($res);
}
?>

And that just outputs the Paypal homepage for some reason, when it should output the checkout page.

I am aware that displaying the paypal page inside my own makes it seems like a phising site, but I'm only displaying it for testing purposes. My aim is to upload my items and re-direct to the Paypal page.

I really need some help on this, if anyone has any suggestions?
