max discount value

-- HikaShop version -- : 5.0.3
-- Joomla version -- : 4.4.3
-- PHP version -- : 8.1.3

Hi guys!

The following is my problem and the task to be solved: I need to set a maximum value for discounts per product, which overrides any preset Hikashop category discounts. What I have:

- A custom field where the value for each product is received from a CRM system (e.g., 30%). The custom field is named "maxkedvezmeny."
- Predefined Hikashop category discounts (e.g., the maximum discount that can be applied is 40%).

However, since not all products within the category can have a 40% discount, the system needs to consider the 30% value from the "maxkedvezmeny" field.

This was previously solved by a developer, and it worked, but it was deleted during a recent update.

Here is the translation:

If I am correct, I need to modify the currency.php file to override the Hikashop discount values when the "maxkedvezmeny" field is smaller than the discount value calculated by Hikashop.

Thanks in advance

Thanks for your help, I've made it through currency.php, now trying to create a plugin!
