        echo "the user is exists";
        }
        ?>
//here will be my second page html 
    //end of second page

what i am doing

  1. In the first part I have been checking the database if the mobile number and password exists .If the mobile number exists then I have been saving them in session to use in another pages and in '$_SESSION['loggedin'] = "true"; setting session as true'.
  2. In the second page I have been checking if the user exists by checking if the session is true but the session value is empty.

Problem

  1. In second page I have been checking if its value is true but its value is empty so I can't let user to use the page.
  2. All other session value is also empty.

Description

  1. This program was working while I hosting them in godaddy .
  2. after I changed to the new server the session is not working like it was working in godaddy

Working Method

  1. If I run these in separate php and call via ajax it is working the session value is 'true' but all my codes are like in first page php, html and javascript all are in single page .
  2. I need a solution how to run them in a single page.

*. This session problem only arise if I use these codes in my new linux server hosting , But in godaddy linux hosting is working fine.

Comment me if any additional information needed.

Since you experienced a different behaviour in two different ambients, I would check the php configuration in the new server for session handling, that is 'session.cookie_httponly' (since you use javascript for redirection), 'session.use_cookies' and 'session.use_only_cookies' .

Besides, I would suggest to force-close the session before doing a redirection, to ensure the session actually writes the data before the new page loads.
