Session Woes...

Alright, sessions are the only thing that totally take a toll on me. Now im not sure if my server isnt configured properly or im just retarded and coding it wrong, but a standard session code like this should work fine correct?

PAGE 1: ---------------------------------------------------------------

<?
session start();
$the_variable = "yea this is a variable";
session_register('the_variable');
echo("$the_variable");
?>

PAGE 2: ---------------------------------------------------------------

<?
echo($the variable);
?>

The variable should show up correct? I get no erroes, but the error that says the variable isnt registered or its undefined..

Now im not sure whats wrong with this situation here, but it doesnt work.. Ive gotten it to work for perhaps 1 page, but once i switch from page 2 to page 3 it stops working again.

Idea? I can include my php.ini if you'd like. Im running on Win2k Adv. Server w/php4 & MySQL.

Your code requires the php directive register_globals to be on. It's preferred to code assuming this directive is off. It's off by default since PHP 4.2.0.

Also, it is MUCH preferred to NOT use session_register() at all. Instead, do this:

page1.php

<?php
session_start();
$_SESSION['foo'] = 'bar';
print '<a href="page2.php">page2</a>';
?>

page2.php

<?php
session_start();
print $_SESSION['foo'];
?>

Also note that superglobals such as $_SESSION became available in PHP 4.1.0

Thanks, time to give that a try.

a nice way to see all the session vars

echo "<pre>";
print_r($_SESSION);
echo "</pre>";

i am having the same problems.

I was able to get a session array to store values with register_globals = on.

now that we have turned them off, i am unable to get the values to load into the array or even to be able to display the array.

This used to work:

session_start();
session_register('userid','mycart');
if (!$_SESSION['userid'])
{ $userid = rand(); }

now it doesnt.

i am trying :

session_start();
//session_register('userid','mycart');
if (!$SESSION['userid'])
{
$SESSION['userid'] = rand();
}

any suggestions?

how do i access certain vaules in the array MYCART?

thanks
