Hi! If i have not a one $value but many $values for instance a prices $values?
Hello,
You can update only one value, not multiple values.
Thanks.
This helper runs automatically and update for all products ?
Hello,
No, the helper is not called automatically.
You have to create an object of the helper and call its setAttributeData() function, then update all the products.
Thank You.
