Session expiry script help

[jonno946]

Hi, i am having problems getting the following to work. any help would be appreciated🙂

When a user logs in, it updates the 'last_login' field with the current time of login.

Then, i need to add an if statement (on refresh) to the following code to check to see if the user has been logged on for 30 minutes. If so, then make the user log in again.

So far i have only managed to do the basic session bit, but can anyone tell me how i can modify the following code to be able to do this?

Thanx

Jonathan

<?php

session_start();
session_register("logged_in");
if ($logged_in == "1")
{
header("Location: secured_area.php");
} else {
header("Location: login_page.php");
}
?>

Sigh...

what's the fun in trolling when people already know you're a troll?

Jonathan;
just run a simple select statement and use the date_sub() function to calculate the age of the record, something like:

SELECT CASE WHEN logondate < date_sub(now(), interval 30 minute) THEN 1 ELSE 0 END AS expired
FROM table
WHERE userid = $userid

now the logondate must be less than the current time minus 30 minutes, which would mean that the logondate is older than 30 minutes.
You'll get 1 or 0, indicating 'expired' or not.
