Authentication for PayPal Express Checkout

I'm using the express checkout button in a number of places so I've placed the code in an include.

When adding the Express checkout button to an eCart page, the update cart button triggered the Authentication so I've changed the code to

if ($_SERVER["REQUEST_METHOD"] == "POST" && isset($_POST["PayPalXpr_x"]))

This works fine, the only problem is that it gets overwritten if I make a change with the wizard.

Is there a better way to trap the pressing of the the pp express button

Cheers

in the Authentication for PayPal Express Checkout server behavior, select the Button PayPalXpr pressed trigger.

this will write the trigger code as:
if (isset($_POST["PayPalXpr_x"])) {

which wont get overwritten


it's not needed to check for both the request method and the button being set, the only way the button will be set is if the request method is POST.

Thanks Jason

cheers

Hi Jason,

The server behaviour vanishes if I use your code, I've just placed the code between

<?php if (isset($_POST["PayPalXpr_x"])) {?> code is between here <?php }>

Which works fine


Cheers
