PHP session_start AND command pattern

[Wingy]

I'm wiriting up some PHP using a command pattern type of design. Here's my directory setup:

/include/command/CommandRouter.php     //  Routes command to proper command object
/include/command/UserLogin.php               //  Class implementing ICommand
/include/command/ICommand.php              //  Command object interface

/admin/index.php         //  admin login form
/admin/main.php          //  admin dashboad from successful admin login

/index.php        //  Normal user login
/command.php  //  Makes a commandRouter, gets the command response, and forwards to result page

I'm running into a problem with session_start and how it only works within a directory. Here's a scenerio.

I'm and admin, I go to www.mysite.com/admin and enter my login credentials.
The form action points to ../command.php?commandName=UserLogin, which calls a UserLogin method to login. This is where user data is stored in the session.

I logged in alright, except because of the session_start issue, when /admin/main.php looks for $_SESSION["Logged_In"], it's empty.

My question is this, how do you all do you session_start stuff and still keep a somewhat complex but neat directory structure, while maintaining some kind of command type pattern as I am?

Thanks

You have to make sure that you call the

session_start()

function before you try to access any session variables. Otherwise, as far as PHP is concerned, the session variable doesn't exist. You can put the function call in the command.php file at the top, if you are using the command.php as a controller for your framework.

With the older (3.x), you had to call session_start() before everything else. I don't know if that's that same with 4 or 5 as I mostly work inside of a CMS anymore, and the CMS takes care of that automatically.

If you want to use a named session, you must call session_name() before calling session_start().
