Finally, I found the solution to my problem.
To send data hidden function (action) controller1 to a function (action) Controller2, I created a session that contains the hidden data in the function of controler1 and I get this session in the function of Controller2.
I followed the following tutorial to create session: http://www.larryullman.com/2011/05/03/using-sessions-with-the-yii-framework/
