Re: [PHP] Session Variables in a Class
Thanks Curt,
You were absolutely correct. Removing the
session_register() lines before the $_SESSION[] fixed
the problem. By mixing the two before, it actually
would register the variable so I could later test for
the registered session variable but it did not retain
the value I assigned it. Thanks again for the help.

You might want to read
http://php.net/session
You are most likley running into a register_globals
issue.
A couple things to note:
. You must not mix $_SESSION[] access with
session_register()
anywhere in your script.
. When you issue session_register('name') inside
your class it is
declaring the global var $name as a session var,
not the $name in
your script.

Re: [PHP] Session Variables in a Class
From: micro brew [EMAIL PROTECTED]
Here's my class. I start the session in the
constructor and in later methods attempt to register
session variables. You can see I've tried a couple
different methods but none of them maintain the
session variable values. Any suggestions?
Is register_globals ON or OFF? You shouldn't mix session_register() with
$_SESSION. Just use one other the other, but I recommend just using
$_SESSION.
$_SESSION['var'] = 'some value';
to set a session var, and
if(isset($_SESSION['var']))
to see if a variable is set.
Also, if you have a varible $foobar within a class method that you define as
a session var, you must make it global if you want to access it in other
methods. The same thing for HTTP_SESSION_VARS. I think you're just running
into a scope issue.

[PHP] Session Variables in a Class
Hi everyone,

them work just fine in a normal PHP page. But when I
create a class and try to define a session variable
within a method in the class it won't work. I've
tried setting the session variable directly

The normal way of setting it -

session_register('name');
$name='somevalue';
- didn't work either (within the class).
Am I just missing something obvious? Any suggestions?
TIA.

You have to include the class-definition _before_ you start the session.
Read about it in the manual:
http://www.php.net/manual/en/language.oop.serialization.php
Hope that helps.

didn't work isn't very helpful to us. How useful would it be for me to
just answer you with it worked for me.
Show us some code examples (short ones) as to how this doesn't work, please.
