Prestashop：优惠券价值 - “blockuserinfo”中合约的总价值

Question

Is it possible to subtract these two values, so that the value changes dynamically depending on the order sum?

<span id="cart_blockuserinfo">
     {displayPrice price=$cart->getordertotal(false)}
</span>
<span>
    <p>{foreach $displayVouchers as $voucher} {$voucher.reduction_amount} {/foreach}</p>
</span>

Answer 1

Probably something like this should work:

<span id="cart_blockuserinfo">
     {displayPrice price=$cart->getordertotal(false)}
</span>
<span>
    <p>{foreach $displayVouchers as $voucher} {$voucher.reduction_amount} ({displayPrice price=$cart->getordertotal(false) - $voucher.reduction_amount}) {/foreach}</p>
</span>
