How to bind a database to a user?

Question

JavaScript

Hello, friends!
I am a student (already a graduate student) in my free time I study objective c (a little more than six months), in a year I have a diploma. As a graduation project, I want to implement an application for notes, here's the question itself:
I can create a user registration form (with sending data to the php mysql database (this is important, everything should be stored outside the phone)), according to the same principle, I can implement the creation of a note by the user, the question is, how can I link the user and his notes so that when he logs out and logs in, he can see his own notes?
Thank you!
I would like in a nutshell, indicate the direction in which direction to go ...

Answer 1

onkeyup="document.getElementById('hiddensumm').value = parseFloat(this.value).toFixed(2)"

Answer 2

the user's table usually contains an id column.
in the note table, create a user_id column that will contain the id of the user who owns the note.
