Redirect AJAX response URL from PHP header

Question

I have an AJAX POST that is sending back a successful response from my PHP file newPNRsubmit.php :

if(isset($_POST['ticketentry'])){
            $_SESSION['ticketEntry'] = 1;
            header("location: pnr-details?id=".$pnrid);
        }

However I would like to use the AJAX response that I am receiving into window.location

This is the response:

XHR finished loading: GET "https://example.com/pnr-details?id=240".

This is my AJAX structure:

$.ajax({
 type: "POST",
 url: "newPNRsubmit.php",
 data: {
 bookingdate: bookingdate,
 airline_id: airline_id
},
 cache: false,
 success: function(data, url) {
 $('#NewPNRModal').modal( 'hide' );
},
 error: function(xhr, status, error) {
 console.error(xhr);
 }
 });
 return false;

How can I correctly parse the URL that I am receiving into window.location ?

UPDATE: This is the response from console tab. The second GET XHR is showing the link I need for window.location . Should I update the header location to send JSON data in my PHP file in order for this to work?

Answer 1

Either return a URL in the body instead of a header, or get the header like so:

success: function(data, URL, jqXHR) {
  window.location.href = jqXHR.getResponseHeader("location");
}
