I have a variable contaning "username" and want to get these values via session to any of the view pages.
How can I get this session variable in the view ?

A basic example of session usage in controllers, views and cells would be: $name = $this->request->getSession()->read('User.name'); // If you are accessing the session multiple times, // you will probably want a local variable. $session = $this->request->getSession(); $name = $session->read('User.name');
Session variables are special variables that exist only while the user's session with your application is active. Session variables are specific to each visitor to your site. They are used to store user-specific information that needs to be accessed by multiple pages in a web application.
Session variables solve this problem by storing user information to be used across multiple pages (e.g. username, favorite color, etc). By default, session variables last until the user closes the browser. So; Session variables hold information about one single user, and are available to all pages in one application.
There's a SessionComponent available in your Controller that you can use like $this->Session->write('Name', 'Value');. Analogously there's also the SessionHelper for the View, which does very similar things and can be used like $session->read('Name');.

You can use $this->Session->read('myParam') in your Views files.
But you can't use $this->Session->write('myParam').
As noted here:
The major difference between the Session Helper and the Session Component is that the helper does not have the ability to write to the session.

To use it in a helper you must remember to include it in your $helpers declaration:
class Foo extends AppHelper
{
var $helpers = array('Session','Bar');
