checkout page coding problem

[foxnetwork]

I have modified the hook in a payment module to only show payment option if the total amount is above 1000 as below

if($cart->getOrderTotal() < 1000) {
       //     return ;
       return;
        }

 

This works great but I want to not show the payment option if someone puts a specific voucher code in there  eg

if($cart->getVoucherCode() = hhdyyhfyr) {
       //     return ;
       return;
        }

Obviously this is wrong. Is there a way of doing this for the checkout page or can I call it from database somewhere to check

Any help appreciated

Hello,

Is your change displaying an error? 

Because the right PHP syntax should be this :

if($cart->getVoucherCode() == "hhdyyhfyr") {
       //     return ;
       return;
        }

Even if it's not the correct way to do this, there is an other method that allow you to handle more than one voucher code :

if( in_array($cart->getVoucherCode(), ["voucherCode1", "voucherCode2", "voucherCode3"]) ) {
       //     return ;
       return;
        }

 

There are 3 voucher codes in this example but you can put more.

The problem is that I tried getVoucherCode() but I dont think this is even the correct way of getting the code

And before the order is created does it put it in the database anywhere I could just pull the information. I know once the order is created then you can get it from the database
