paypal-ipn

问题 I know how to make a PayPal donate button redirect after payment, but what I need to know is, can you pass the payed amount through this redirection. So it would redirect to http://example.com/donate?amount=123 , is this even possible? Thanks! EDIT: It seems I can do it with IPN(?), I just don't know how to use paypal's IPN, can anyone help me? (yes I have read the docs, they are confusing) 回答1: yes it is possible, like so: <!-- where you setup your paypal button : --> <input type="hidden"

问题 After 2018 June 30th, Paypal won't accept non-TLS 1.2 + HTTP 1.1 requests anymore. They created the URL https://tlstest.paypal.com/ to test if connections are OK. If we open this URL in a browser, we get a successful: PayPal_Connection_OK Quesiton: why does it fail when connecting from PHP with the following code? (I get no response at all, the browser is still in waiting "state" like this, so it doesn't even arrive at echo $errno; echo $errstr; ) <?php $req = ''; // usually I use $req = 'cmd
