You are all declaring:
----------------------
session01.php
----------------------
<?php
session_start();
...
?>
----------------------
session02.php
----------------------
<?php
session_start();
...
?>
I have found it NECESSARY to redeclare session_name() as follows:
----------------------
session01.php
----------------------
<?php
session_name("Foo");
session_start();
...
?>
----------------------
session02.php
----------------------
<?php
session_name("Foo");
session_start();
...
?>
I give you the case of session01.php whose form calls session02.php. In session02.php, I include
session02.inc to display an image when session02.php?display=1
<?php
if(!$displayimage)
{
//display html text and
<img src="session02.php?display=1"> //somewhere on the page
}else{
include ("session02.inc");//display just the image
}
?>
I found by the school of hard knocks that you need both:
session_name("Foo");
session_start();
I had to declare session_name and session_start in session01.php session02.php AND session02.inc to
pass data correctly. If not session02.php?display=1 received nothing, even if it could spit back the
session_id, even if it was included in session02.php.
I made the mistake of believing because session02.php?display=1 was receiving data that
session02.php received.
