Save variable after refresh php

Question

I have a code that saves the POST from an html form in the $ID variable, in case when this POST occurs the page changes due to this variable, so I would like to save it somehow so that I didn’t lose it when I refresh the page, so that the page doesn’t change.

To solve your "problem" I recommend that you save this variable in a session, or even in a cookie to be able to use it later.

If you wanted to save in a session, on the page that takes the data from $_POST, you could enter this code:

<?php
     session_start();//Colocar no inicio do código, se já não houver em alguma página que da include nessa
     //resto do código
     $id = $_POST['form'];
     $_SESSION['dados'] = $id;
     //resto do código
?>

Now to recover that data on any other page, you do the following:

<?php
     session_start();//Colocar no inicio do código, se já não houver em alguma página que da include nessa
     //resto do código
     $id = $_SESSION['dados'];
?>

Remembering that by being SESSION, as soon as the browser is closed, this data will be "removed" from SESSION.

If you want to know about Cookies, this that page.
