Using $_SERVER['QUERY_STRING']

[xfire123]

Hello! I have a problem.  Can you help me please.

 

A user is entering two dates in to a form. When he press submit the date pass in another opened page and doing stuff.

Can i pass this variables to one more php file. He create a json file. I need to create this json right after user hit submit and then redirect to the page.

 

Im using this to redirect and pass the two dates

            header("location:gentable_chart.php?" . $_SERVER['QUERY_STRING']);
            exit();

I need to pass the variables one more time to create the json before the redirect. Any idea how to do this?
