Getting referer info from Paypal successful payment?

Question

Let's say someone paid successfully and redirected to my "successful payment" page. Can I track the referer url by

$_SERVER['HTTP_REFERER'];

I want to do this because I should show "thank you" page only if visitor comes from paypal.

Answer 1

I can't get echo $_SERVER['HTTP_REFERER']; to display the PayPal referring URL after a transaction completes and I'm taken back to my return URL. I did try some other tests to make sure the command worked - and it did. I can get the referring URL to appear.

I did a bit of research and apparently PayPal hides that information. I'm not sure why though but I'm sure it has something to do with security - sorry.

If you're looking to verify information when someone navigates to your return page you can use Payment Data Transfer.

Answer 2

由于PayPal使用HTTPS，因此只有在使用HTTPS （ 而非HTTP ）的情况下，您才可以跟踪引荐来源网址。
