CakePHP session reading a variable that is not set

Question

The main question is, I set the variable (facebook id) in the cakephp session, if the user is on facebook, if the facebook id is set in the session, I want to do something else. How can I check this?

I am doing something like:

if(isset($this->Session->read("fbid")) && $this->Session->read("fbid") != "") 

Is it correct?

Thanks in advance!

Answer 1

The session component has a method called check.

 if ($this->Session->check('fbid')) { //fbid exists in session }
