using Codeigniter session class across multiple php files (controllers)

I have two controllers, user and module. By default the user controller is loaded and the user first logs in. Once the user is authenticated (by the school), a token is issued which is used to make all the calls to the school's API. I create a session and store the token in it.

$this->session->set_userdata('token', $_GET['token']);

After login I 开发者_C百科need to display the user's registered modules (basically subjects) for which I create a object of the module class and call a function to show the modules. The module calls makes a call to the API to get the list of registered modules. For this I need the token so i try to access the token through:

$this->session->userdata('token');

But i get an error: "Message: Undefined property: Module::$session"

the user.php file has a class User in which all functions are defined (redirecting to login page and storing the token in session) while the module.php file has a claa Module which makes a call to the api to get the list of registered modules.

The session class is set to autoload!

hope this one solve your problem :)

General problems regards loading libraries, and hooks

I followed Phil Sturgeon's advice on setting up a base class to extend from. This way you don't have to keep defining the same session stuff across multiple classes.
