Is it possible to make the final discount less than 10%?

Question

opencart

Can it be implemented in such a way that during the final pricing, the total final discount will never be more than 10%?

Answer 1

catalog/model/total/total.php - model responsible for the Total
In it you need to:
1. Get subtotal - $this->cart->getSubTotal(); (it most likely already takes into account the discount for the customer group)
2. Check the customer group $this->customer->getCustomerGroupId();
3. Calculate the desired total with a 10% discount, suppose we call the variable $totalten
4. Replace

'text'       => $this->currency->format(max(0, $total)),
'value'      => max(0, $total),

on the

'text'       => $this->currency->format(max(0, $total, $totalten)),
'value'      => max(0, $total, $totalten),
