Show coupon code in checkout

[andevit]

Hi,

I'm a newcomer on Prestashop.

I have this issue: in the checkout if i add a coupon code, I would like to show the coupon code instead of the coupon name.

Can i override the file src/Adapter/Presenter/Cart/CartPresenter.php?

I found the function getTemplateVarVouchers() that I would like to override. Is it possibile?

You can modify file: Fsrc\Adapter\Presenter\Cart\CartPresenter.php

function: getTemplateVarVouchers

Change

$vouchers[$cartVoucher['id_cart_rule']]['name'] = $cartVoucher['name'];

To

$vouchers[$cartVoucher['id_cart_rule']]['name'] = $cartVoucher['code'];

Because prestashop does not allow overrride SRC directory
