How to read and write Session in Cakephp 3.0

问题

I am new to cake 3.0. I have read documentation on http://book.cakephp.org/3.0/en/development/sessions.html But I am not able to write sessions.

use Cake\Network\Session\DatabaseSession;

$session->write('Config.language', 'eng'); 
$session->read('Config.language');

回答1:

You need to set $session :

$session = $this->request->session();
$session->write('Config.language', 'eng'); 
$session->read('Config.language');

And then you'll be able to read and write in your session

Or you can direclty read and write :

$this->request->session()->write('Config.language', 'eng');
$this->request->session()->read('Config.language');

I use this its works fine

$session = $this->request->session();
$session->write('annul_income','$100,00,00');//Write
echo $session->read('annul_income')//To read the session value   o/p:$100,00,00

Prior to 3.6.0 use getRequest() and getSession() instead.

$name = $this->getRequest()->getSession()->read('User.name');

And if you are accessing the session multiple times, you will probably want a local variable.

$session = $this->getRequest()->getSession();
$name = $session->read('User.name');
