I have a website in Presta where user can enter custom price, there is a mix/max price from backend, now e.g. the max price is $50, i dont want people to add more than $50, currently they can, i checked with the developer of site, he says PS 1.7 loads product page content via ajax and he can not do this.
I was suggesting like we check price in validation and do some code there.
how can i do this in presta, any clue!
