Automatically update $ _SESSION variables without updating

I am using the $ _SESSION variable to send emails via AJAX (they need to be sent without refreshing the page), but the $ _SESSION variable is not automatically updated, so when it changes I need to refresh the page before updating the variable.

Is it possible to update the $ _SESSION variable without updating?

This is the code I am using to send email:

$(document).ready(function(){
    $("#medicalembassy").validate({
        debug: false,
        rules: {
            name: "required",
            email: {
                required: true,
                email: true
            }
        },
        messages: {
            name: "Please let us know who you are.",
            email: "",
        },
        submitHandler: function(form) {
            // do other stuff for a valid form
            $.post('http://www.example.co.uk/erc/process.php?imei=<?php echo $_SESSION['imei2']; ?>&send_type=2', $("#medicalembassy").serialize(), function(data) {
                $('#results').html(data);
            });
        }
    });
});

This way, if the $ _SESSION variable changes, I need this AJAX email to recognize it without having to update.

Thanks for any help

The variable A $ _SESSION is obtained by running "session_start ();" and cleared if you use "session_destroy ();". However, you cannot get changes in session variables multiple times in the same document: the document that requests AJAX will see the changes in $ _SESSION every time that page was requested (a page inside AJAX).

Make your PHP script return JSON containing both the html results and the new value from the session. Then, on a successful callback, you update whatever needs to be updated with the session value.
