How to use Session in this code. Unable to understand

Question

I'm trying to use Session in this basic login page. Where and how do I use Session? Thanks. I saw many examples of use of session but please pinpoint where I can add it. I am new to PHP coding.

few notes: 1) center has now been removed from the HTML markup - center stuff using CSS 2) don't use inline styles, it's hard-to-read and hard-to-maintain. 3) b is also not preferred, use `` instead — treyBake, Apr 25 '19 at 09:55
what have you tried with `$_SESSION`? you only need to use it in the login validation -not the login form (well, I guess you could and should check if user is already logged in - but come to that later) — treyBake, Apr 25 '19 at 09:55
`$_SESSION` has to set in the page where you handle login validation(In your case - loginn.php). — the.marolie, Apr 25 '19 at 09:58
This is a bit too broad for SO's simple Q/A format, you really need a full blown tutorial on [maintaining application state with sessions in PHP](http://www.devshed.com/c/a/php/introduction-to-maintaining-the-state-of-applications-with-php-sessions/) (*<-- for example, from a quick search*). — CD001, Apr 25 '19 at 10:07

In your loginn.php page. at the top of the page start the session. like

session_start();//this

then search input Mobile_No and input Password in your data base if found then assign session variable user_id like

$_SESSION['user_id'] = $user->ID;

note: if any page already have session_start(); function then write ob_start(); function.
