Why can't I access session variables from my AJAX-called PHP script?

Question

I have one PHP script with a session variable, set like so:

$_SESSION[\'VAR1\'] = \"test\"

Now, I am using AJAX via a jQuery-initiated POST

Answer 1

In jQuery or JavaScript, you can get the session value like this:

var StepIndexval = '<%= Session["StepIndex"].ToString() %>';

alert(StepIndexval);
