Storing Sessions In Database Query

[Necuima 15]

Hi,

 

I am having problems understanding just how to use this. On page 84 there is a diagram showing the procedural flow.

 

I can successfully create the session and load some data into it.  A check of the database table shows that the data is correctly loaded.

 

The problem that I am having is retrieving that data in a separate PHP script.  The comment on the bottom of the diagram says that every time that a session is started the 'open' and 'read' functions are called. 

 

How do I 'see' what is in the session in the second script, i.e., one that gets invoked after the session is initially created?

 

If I do a if (empty($_SESSION)) (after the 'session_start()') it tests as empty?

 

If I do a get_defined_vars(), again after the 'session_start()', it shows that the session is empty?

 

My environment is:

. Windows 7 Home Premium 64 bit
. Internet Explorer 10
. Firefox 22.0
. Dreamweaver CS5 as the text editor

. XAMPP for Windows 1.8.3 which comprises:

.. Apache 2.4.4

.. PHP 5.5.3

.. MySQL 5.6.11

.. phpMyAdmin 4.0.

 

Any help will be most appreciated.

 

Thanks, Necuima

OK, found what I was doing wrong.

 

I probably didn't read Larry's notes closely enough.

 

In a nutshell, I interpreted the 'session_start()' literally (Figure 3.4 - the 'some other script'). What I needed to do was to include the db_sessions.inc.php file which starts the session anyway.

 

Posted here in case it may help someone else!

 

Cheers from Oz, Necuima.
