How to get session information in cakephp

In the controller you can use

$this->Session->read();

to get all details of session variable . And you can use

$this->set('session',$this->Session->read());

to use these values in corresponding view page.

-----------------------------------------------------------------------------------------------------------------------

If you wish to use session variable in each page then use set method in appcontroller to set its value

public function beforefilter(){
$this->set('session',$this->Session->read());
}

Now this session variable is accessible in every page of view.

Note: this should be placed in Appcontroller...
