Value of session variable missing when pass to new page

rejoice

I am using PHP 4.0.6.

The value of the $HTTP_SESSION_VARS missing when pass to another page. The output from page2.php is blank.

Can anyone help me find out what wrongs with it. It work fine in PHP later version but not 4.0.6 😕 😕 😕

Here is my code:
page1.php

<?
session_start();
$HTTP_SESSION_VARS['userName'] = "ABC";
?>
<HTML>
<HEAD>
<TITLE>Untitled Document</TITLE>
<META HTTP-EQUIV="Content-Type" CONTENT="text/html; charset=iso-8859-1">
</HEAD>

<BODY>
<? echo $HTTP_SESSION_VARS['userName']; ?>
<A HREF="page2.php">Next</A>
</BODY>
</HTML>

page2.php

<?
session_start();
?>
<HTML>
<HEAD>
<TITLE>Untitled Document</TITLE>
<META HTTP-EQUIV="Content-Type" CONTENT="text/html; charset=iso-8859-1">
</HEAD>

<BODY>
<? echo $HTTP_SESSION_VARS['userName']; ?>
</BODY>
</HTML>

I have no idea,but have you try to use $SESSION['userName'] instead $HTTP_SESSION_VARS?? I suposse that it doesn't change nothing but, try it!
Good luck!

<?
session_start();
$HTTP_SESSION_VARS['userName'] = "ABC";
?>
<HTML>
<HEAD>
<TITLE>Untitled Document</TITLE>
<META HTTP-EQUIV="Content-Type" CONTENT="text/html; charset=iso-8859-1">
</HEAD>

<BODY>

<A HREF="page2.php?<? echo(SID); ?>">Next</A>
</BODY>
</HTML>

that should send the session details to the page2.php

common_ground

In earlier vesions of php you had to set sessions like this
session_start();
session_register("userName");
instead of $HTTP_SESSION_VARS['userName'] = "ABC";

I have tried session_register as well as passing the SID. The session_id() show the same session, but the value of $HTTP_SESSION_VARS still cannot transfer to page2.php

What's wrong?😕 😕 😕

I just wonder is this one of the PHP version 4.0.6 bugs?

Here are some guidelines from my own experience with sessions.

make sure you have session_start() at the top of every page you
want to use sessions.
If you have a php version that supports $_SESSION use that.
Check php.ini if register--globals is enabled
If you are not passing the session ID make sure php is compiled with trans--id
Try to avoid SID, especially if your passing sessions to multiple browser windows (ex: pop-up). Use ?<?=session_name()?>=<?=session_id()?> instead of SID.

 
<A HREF="page2.php?<?=session_name()?>=<?=session_id()?>">Next</A>

Thanks edspace for your clear guideline.

I don't own the server, I just check the phpinfo() and these are the outcome.

Server contains Linux, Apache, MySQL, PHP 4.0.6

I did put session_start() in every page.
PHP 4.0.6 does not support $_SESSION. So, I used $HTTP_SESSION_VARS
register_globals is on, but I still prefer using $HTTP_SESSION_VARS for security purpose.
Can you explain more by trans--id? I am not sure about it, can I check from phpinfo(). Is this done by server owner?
I have tried it. For PHP 4.2.3 is ok, but for PHP4.0.6 the problem still the same. The session id and name is passed. Both pages have same session id. The value of $HTTP_SESSION_VARS['userName'] still missing in page2.php

I have attached a screen capture of the phpinfo of my server on the section of session. May be you might want to take a look.

Thanks.

Screen Capture of phpinfo() of the server.

Have you tried just testing the session variables globally .ie not $HTTP_SESSION_VARS

<?php
session_start();
session_register("userName");
?>
<HTML>
<HEAD>
<TITLE>Untitled Document</TITLE>
<META HTTP-EQUIV="Content-Type" CONTENT="text/html; charset=iso-8859-1">
</HEAD>

<BODY>

<? 
$userName = "test";
echo $userName; ?>
<A HREF="temp2.php">Next</A>
</BODY>
</HTML>

page 2

<?
session_start();
session_register("userName");
?>
<HTML>
<HEAD>
<TITLE>Untitled Document</TITLE>
<META HTTP-EQUIV="Content-Type" CONTENT="text/html; charset=iso-8859-1">
</HEAD>

<BODY>
<? echo $userName ?>
</BODY>
</HTML>

PHP 4.0.6 is buggy with regard to sessions. Might as well save a lot of grief and just upgrade.
