[SOLVED] Simple Session Question

[chocopi]

• Firstly, once you have started and registered the sesssion when you change page does the session continue or do you have to call it?
   
  
• 
  Secondly, how can you check if the session has been started and if its false then they are redirected to the login (to stop users from going to pages without logging in)
  

 

Thanks,

You don't register sessions, if your talking about session_register() it has long been depricated.

 

Sessions are passed from page to page but each page needs a call to session_start(). To check a session variable has been set, use something like....

 

<?php

  session_start();
  if (!isset($_SESSION['logged'])) {
    // user is NOT logged in.
  }

?>

okay thanks, but in your code where did the 'logged' be come from ?

[trq]

You set that when you actually log the user in.

[chocopi]

so you would have a variable set as

<?php
$session = 'logged';
?>

[trq]

so you would have a variable set as

 

No... more like...

 

<?php

  // code to varify valid user goes here.
  session_start();
  $_SESSION['logged'] = true;

?>

ok thanks, just out of intrest could you replace the 'logged' past with user id which is taken from the database

 

Yeah... you can replace it with whatever you think you'll need to follow a user around with. for a login system, I usually use a few variables. Something like...

 

$_SESSION['logged'] = true;
$_SESSION['uname'] = $row['uname']
$_SESSION['perms'] = $row['perms']

 

Where $row is the users record pulled from the database upon login varification.
