So, you're trying to hide the 1 EURO unit price so that the only thing showing is the total amount they're buying?
It the 1 EURO price really confusing people? It only shows in that one place. Everywhere else in the PayPal process it's going to show the aggregate final purchase amount, and the customer will always be confirming the final amount, and not the individual unit price.
I think this is the first time someone has ever *wanted* to hide the unit price ... everyone else has begged for *showing* the unit price with all the line-item details.
There are lots of sites using the same donation approach as kuroi described, and they don't seem to be bothered by the unit price being displayed.
To do what you're asking, while not recommended, can be accomplished by editing /includes/modules/payment/paypalwpp.php and adding an extra line as shown:
Code:
function getLineItemDetails($restrictedCurrency) {
return array();
global $order, $currencies, $order_totals, $order_total_modules;
