paypal-ipn

问题 I am having trouble getting Paypal's IPN integrated into my php, i have the following script and it keeps falling through to the default case when a payment is made in the paypal sandbox. Any help would be appreciated! $request = "cmd=_notify-validate"; foreach ($_POST as $varname => $varvalue){ $email .= "$varname: $varvalue\n"; if(function_exists('get_magic_quotes_gpc') and get_magic_quotes_gpc()){ $varvalue = urlencode(stripslashes($varvalue)); } else { $value = urlencode($value); }

问题 I am using PayPal API of php. It was ok since 2 years but now its creating problems for some customers. Some of the orders are fine but for few users, the transaction is completed but API doesn't response (throw empty response). I don't think it will be because of code issue.

问题 I need to create dynamic 'Pay Now' buttons on my site, and PayPal says the way to do this is via an HTML FORM with preset variables for the price, currency, and item of the purchase. I use PayPal IPN to notify me when a payment has complete. However, what's to stop someone from modifying the query parameters of the Pay Now button to change the price? Some people have told me to redirect the button through a PHP file that sends you to a PayPal payment page with the parameters in place, but the

问题 I have a web site thats been operating for months, if not years. It takes payments via PayPal. IPNs are used to track the payment status against an order. If the paypal account owner issues a refund, the IPN from that is tracked, and the order updated with the amount refunded. Now: The problem: This was all working in February 2015. But since then I have made 4 refunds (buy logging into the PayPal website and refunding). Each one was days apart. In each case they were partial refunds. In all

问题 I am trying to get my PayPal IPN Listener to work on my Live environment, it works on Staging perfectly and the issue is something to do with the web.config file: (http://pastebin.com/B8YhJEZK) I am using "https://developer.paypal.com/us/cgi-bin/devscr" and the Instant Payment Notification (IPN) simulator to test the web service however I am getting the following: "IPN delivery failed.

问题 I've been bashing my head against a brick wall the last few days on minor problems. This time I am on the final piece to the puzzle. In my php function of a wordpress cart plugin I have the following: Relevant Function - http://codepad.org/uDm3q9yp Paypal Class - http://codepad.org/friBthoO I manage to go through the purchase fine.

问题 I have built an application, that sends a notification url with the GUID of the logged in user to PayPal, and upon completion of purchase, the url is called, and after verification, the user database entry updates the column purchased from 0 to 1. The user then clicks the return to app button, and the premium functionality displays based on the purchased column.
