Hello, I created these functions that automatically create new multiple-choice questions on my page. I can create as many questions as I want, and in these answers I can have as many answers as I want. I want to write these answers and questions in the mysql database. What I have no idea how to do is how I get the id of each question and every answer. I could not think of a logic for the answers to always have an order.

The Ideal for Single Id is to work with Guid.

I use this function in javascript to generate my Guid. 

    function createGuid() {
        function s4() {
            return Math.floor((1 + Math.random()) * 0x10000).toString(16).substring(1);
        }
        return s4() + s4() + '-' + s4() + '-' + s4() + '-' + s4() + '-' + s4() + s4() + s4();
    }

All you need is a new Id just call the function as follows: 

var seuObjeto.id = createGuid();
