Prevent session expired in PHP Session for inactive user

Question

I have a problem with my application: my application has many forms and need about 1 hour to finish this form because the form is dynamic (can add other forms). The problem

Answer 1

Here an example to prevent session timeout by using a jQuery Ajax call:

var refreshTime = 600000; // every 10 minutes in milliseconds
window.setInterval( function() {
    $.ajax({
        cache: false,
        type: "GET",
        url: "refreshSession.php",
        success: function(data) {
        }
    });
}, refreshTime );

in the refreshSession.php you can do something like session_start()
