PayPal

Has anyone got code they want to share on how to send a secure form to PayPal for processing? One other sample I tried looking at was too extensive code wise to help me out. I'm still fairly new to PHP et al. so if you don't mind I need a walking through or providing a well documented sample.

Thanks in advance,
Marcel.

Anon

Thanks in advance.

Yes, I put together a script using cURL to make a secure post to Paypal. I posted my script on the general board in the third week of December under the title:

Complete Script for Paypal's IPN Service

It is resource intensive during the process. If you make improvements on it, please let me know.

can you post the exact link in this thread?

I can't seem to find it.

I've almost finished a PHP/Flash frontend Paypal interface which I'll gladly make available to anyone once I'm done.

send me an email and I'll keep it

here's the links to the PAYPAL PDFs on how to set up the variables.

after that, it's simple PHP.

https://www.paypal.com/html/shopping_cart.pdf
https://www.paypal.com/html/single_item.pdf
https://www.paypal.com/html/subscriptions.pdf

it includes sample Perl Scripts which can easily be converted to PHP.

The problem, it would appear is converting
the code that does the postback to paypal...

post back to PayPal system to validate

use LWP::UserAgent;
$ua = new LWP::UserAgent;
$req = new HTTP::Request 'POST','https://www.paypal.com/cgi-bin/webscr';
$req->content_type('application/x-www-form-urlencoded');
$req->content($query);
$res = $ua->request($req);

How do you do this in PHP - anyone know?

Anon

I found this script somewhere on the net. The only problem is I haven't used it 'live' yet, and PayPal don't offer a 'test' facility. I'm new to php, so if any 'real coders' can spot any glaring mistakes it would be appreciated!

<?
while (list ($key,$value)=each($HTTP_POST_VARS))
{
echo "$key:$value /n";
$postdata .=$key.'='.$value.'&';
}
$postdata .= 'cmd=_notify-validate';
$url = '';

$command = '/usr/bin/curl -m 120 -d "'.$postdata.'" https://www.paypal.com/cgi-bin/webscr -L';
exec($command, $return_array, $return_value);

if ($return_array[0] == 'INVALID') {
include("../private_html/problem.inc");
}
else if ($return_array[0] == 'VERIFIED') {
include("../private_html/thankyou.inc");
}
else{
echo("Thank you for your order - we appreciate your business. Unfortunately, we have not received the response we expected from PayPal's server, and cannot provide immediate confirmation of your transaction; we will contact you shortly by email to update you on your order status. If you prefer you may check your PayPal account to verify whether the transaction completed successfully, and email details to me");
}
?>

Has anyone tried this script?

I'm looking the PayPal manuals now.
They maybe could be written a little more clearer.
But it sounds like the IPN is done between the backend servers.
The script given here checks the return results and tries to "echo" a response. Who would see this?
Or does the IPN script replace the "return" and "cancel_return" URLs defined in the form posted to PayPal when someone buys??

Anon

I get the impression that you have a return url (both for successful and unsuccessful payments), eg www.yoursite.com/result.php

This page contains the script for IPN.

PayPal sends the info to the page which is then retuned to PayPal for verification; PayPal then returns a 'success' or 'error' message.

Your /result.php page can then display the relevant info, eg 'Your payment was successful' or 'there seems to be a problem'. The cancel url could also use this page so that it displays the 'problem' info if the user cancels the paypal transaction.

That's my impression!

Anon

But the instance of result.php that paypal's server posts to isn't the same as the instance of result.php that the buyer might be at.

It seems you will have to have the buyer be on a page that will repeatedly query the db to see if the transation gets completed. Then it will post the message once the instance of result.php that paypal's server calls posts to the db.

Does anyone have any suggestions for testing one's scripts?

I know I won't get the syntax right the first time, and probably not the second. I don't want to do a live transaction everytime I want to test my scripts. How do I make sure the db updating, and the interaction with Paypal's servers, are working as they should without testing live?

it's simple. Use the Switch function in PHP

PayPal uses a variable that lets you know if the payment was successful, failed, pending, etc.

use the value of that variable in a PHP switch ($variableHere){

case:"pending"
code here

case:"successful"
code here

case:"failed"
code here
