read here

 

endless information.

[paulman888888]

so do sessions automaticly go to the next page?

You need to put

<?php
session_start();
?>

at the start of each script where you want to use sessions.

you can post stuff over from other pages if thats what your getting at ?

[paulman888888]

Just to clarify.

 

Page 1

<?php
session_start();
//then loads of session stuff
?>

 

Page 2

<?php
session_start();
//the session variables has been past on from page 1
?>

 

Page 3

<?php
session_start();
//will the variables from Page 2 still come though to this Page?

?>

 

Thankyou

Paul

When you start a session on the page, it loads automatically the $_SESSION array with the values you gave it, if the session is still alive.. so it will load the session values in the 3rd page

The $_SESSION array will contain everything that you put into it from which ever script. It's cumulative. By default the session goes away when you close the browser.

 

Try these three scripts:

one.php

<?php
session_start();
echo '<pre>' . print_r($_SESSION,true) . '</pre>';
if (isset($_SESSION['one']))
   $_SESSION['one']++;
else
   $_SESSION['one'] = 1;
?>

two.php

<?php
session_start();
echo '<pre>' . print_r($_SESSION,true) . '</pre>';
if (isset($_SESSION['two']))
   $_SESSION['two']++;
else
   $_SESSION['two'] = 1;
?>

three.php

<?php
session_start();
echo '<pre>' . print_r($_SESSION,true) . '</pre>';
if (isset($_SESSION['three']))
   $_SESSION['three']++;
else
   $_SESSION['three'] = 1;
?>

Invoke them in any order in the same browser and see how the $_SESSION array changes.
