Need a very simple Paypal setup

Hi,

I need to know how to set up a very very simple paypal system, where a customer hits the buy now button, pays via paypal, and is then emailed either an attachment or a password to a secret area.

I've had this set up before and I know it's very simple so I know I don't need to pay for it. I've played with the code a bit myself but it's been a while. I used IPN.

Can anyone point me to a simple php script to set up this system? I could do the email stuff myself, I just need to handle the paypal info. It's only one ebook.

 

I think here http://www.pixelmill.com/support/support_article.aspx?ArticleID=kb101591 you can get all informations you need.

 

Thanks, but not quite. I need info on how to wire this up to the php script.

 

Hi you could set up an account with Payloadz.com.

The customer clicks to purchase. Pays. And an email is sent with a file to download.
You could include the password within that file. (A .txt file within a .zip file perhaps)
Very simple.

I've been doing this for about 3 years with Payloadz.com

Hope this helps.

 

Thanks.

But I found the answer on the paypal site. I use this script and simply send an email to the customer containing their download info.

// read the post from PayPal system and add 'cmd'
$req = 'cmd=_notify-validate';

foreach ($_POST as $key => $value) {
$value = urlencode(stripslashes($value));
$req .= "&$key=$value";
}

// post back to PayPal system to validate
$header .= "POST /cgi-bin/webscr HTTP/1.0\r\n";
$header .= "Content-Type: application/x-www-form-urlencoded\r\n";
$header .= "Content-Length: " . strlen($req) . "\r\n\r\n";
$fp = fsockopen ('ssl://www.paypal.com', 443, $errno, $errstr, 30);

// assign posted variables to local variables
$item_name = $_POST['item_name'];
$item_number = $_POST['item_number'];
$payment_status = $_POST['payment_status'];
$payment_amount = $_POST['mc_gross'];
$payment_currency = $_POST['mc_currency'];
$txn_id = $_POST['txn_id'];
$receiver_email = $_POST['receiver_email'];
$payer_email = $_POST['payer_email'];

if (!$fp) {
// HTTP ERROR
} else {
fputs ($fp, $header . $req);
while (!feof($fp)) {
$res = fgets ($fp, 1024);
if (strcmp ($res, "VERIFIED") == 0) {
// check the payment_status is Completed
// check that txn_id has not been previously processed
// check that receiver_email is your Primary PayPal email
// check that payment_amount/payment_currency are correct
// process payment
}
else if (strcmp ($res, "INVALID") == 0) {
// log for manual investigation
}
}
fclose ($fp);
}
?>

Thank you Stu for sharing the code. I keep it for the day I will need it!

 

I have something similar I offer for google checkout. Call it Google-Digital-Chekcout and sell it for 15.00 to people looking for a quick solution to digital delivery. I dont know why i chose google checkout. Who has the better rates anyone know off hand? Cause seeing any skimmed off the top makes me cringe.
