Discount percent problem for importing products from xml

[bloods]

hi, sorry for my english

i am moved from woocommerce to prestashop, i am using xml from my suppliers

i am importing products with normal price and discounted price (for striked old price) but prestashop is not automatically calculate the discount percent, therefore in product page normal price is not showing up, only showing discounted price

how to solve this?

example: 119$ is normal price (be striked), 80$ discounted price

product shows only 80$ price, not show 119$  -  80$

And you can't calculate percentages from two prices?

// price 119

// discount price 80

$percentage = ((80 / 119) * 100);

// result 67.22689076%

 

$product = new Product((int)$id_product);

$product->price = $xml_price;

$product->reduction_price = $xml_discount_price;

$product->reduction_percent = $percentage;

$product->reduction_from = '2021-02-15';

$product->reduction_to = '2021-05-15';

$product->update();
