Using gravity form product field type, I would like to dynamically change the price field depending the quantity field. For example :
if the user type 10 in the quantity field, price may become 1 €. If the user type 20, price become 2 €, ... I need to dynamically set price depending on quantity value.
I saw this link without real answer :
The grid that fix price depending the quantity range can be long (arround 50 lines)
I'm a beginner in gravity form with some knowledge in PHP. What is the best way to do that. Can it be done with some hook ?
