How to check if at least one field is filled?

Question

CMS

Good day!
There is a form, and a check is needed so that if the user once entered something in any field and switched to another field, then the event will fire. And in the following attempts, the event does not work.
At the very thought of switching flags arises (false to true or vice versa). Thank you.

Answer 1

I would also suggest paying attention to OpenCart , it supports all the functionality you declared (most of the box, the rest are modules).

Answer 2

www.opencart.com ? If it's not enough with the modules, then write your own.

Answer 3

wordpress + woocommerce

Answer 4

Hello, I don’t see the code, I’ll assume that there is a certain Input class that we use to work with form elements, it has model fields - which stores the value itself, and for example validation - which stores the fields: dirty, error, hang up a blur event, which, respectively and control the state of your input already in the methods, and then render everything you need
