How to leave two identical forms on one page?

Question

PHP

There is a website with an order form based on such a script. By design, both forms should send the same data. One form hides in a modal window. here it also does not work, even using serialize(). Help me please!
Actually, the site itself: tsvet-nochi.ru

Answer 1

The form uses IDs, replace with classes in html, css and js. Everything will work.
- if the element already has classes, add it separated by a space (class="class1 class2")
- remove the id
- in css and js, replace the pound sign (#) with a dot (.)

Answer 2

By the way, you can not duplicate the form, but clone it by clicking

$.clone(true) // clone withDataAndEvents (default: false)

if using jquery.
