Pay with paypal by link in confirmation email

Hi,

Change the line:
$order = $class->loadFullOrder($order_id,true);
to:
$order = $class->loadFullOrder($order_id,true,false);
in the "pay" function of the file components/com_hikashop/controllers/order.php and the link will work for guests too.
I don't recommend that though as it means that anyone could pay guest orders (the big concern for security here is that anyone can see the content of the order and the data of the customer on the payment gateway's payment page).

Hi,

Yes. Create a custom HikaShop plugin to generate a hash code in the order data in the hikashop_order table when the order is created, then, modify the order creation email notification to add that hash code in the pay link, and finally, modify the code in components/com_hikashop/controllers/order.php in order to check that the hash in the link matches with the one in the database.
