Question

I get the value of $_SESSION[balance] from a MySQL database on every login. How can I update the value in clients browser without reloading the page every 5 minutes? I think it can possibly be done using AJAX?

Sorry if that’s too vague I’m absolutely clueless as to where to start on this.

Answer 1

your’re right, you need AJAX for this. easiest way is to use $.get(); with the jQuery library

js/jQuery script

window.setInterval(function() {

    $.get('script.php', function(balance) {
        $('#balance').html(balance); // set the value to the element with the ID balance
    });

}, 60000); // execute every minute

in script.php you simply query the database for the balance and echo it
