Do I need to include something in the second php page

I have 3 php pages. In the first page I have this code below:

      $_SESSION['teacherforename'] = $dbTeacherForename;
      $_SESSION['teachersurname'] = $dbTeacherSurname;

Open in new window

In the second page I do not have any code posting or containing the session variable on ` $_SESSION['teacherforename']`, `$_SESSION['teachersurname']`.

In the third page I have this code below:

    if (isset($_POST['teacherforename'])) {
    
    $_SESSION['teacherforename'] = $_POST['teacherforename'];
    
    }
    
    if (isset($_POST['teachersurname'])) {
    
    $_SESSION['teachersurname'] = $_POST['teachersurname'];
    
    }

Open in new window

But what my question is that do I need to include something in my second page like a post or a session variable? In other words in the second page may I also have to include the same code I have in the third page?

All you need on the third page is for the second page to post a form to page three with the information you need so that $_POST is available and for the session all you need is session_start(); at the beginning and you can use the session information provided page one and three come from the same domain.

@haloexpertsexchange You see the problem is that in the third page, I am using an ini_set() where it extends the session expiry time. The only problem is that out of all of the $_SESSION variables in the third page, only 2 session variables expire earlier than the allocated time and them 2 are:

$_SESSION['teacherforename']

Open in new window

and

$_SESSION['teachersurname']

Open in new window

THe only reason that these 2 session variables are expiring is that the other session variables are posted from the 2nd page, while the 2 expiring session vairables are posted from the first page. Do I need to change my code a bit in third page or do I need to include something in 2nd page? I do have session_start(); in all the pages by the way.

Note that if you are using session_start(); properly, the session timer is reset every time you access one of the pages in the session. That affects All of the $_SESSION variables. They all expire when the session expires.
