Question

I am developing a website with Yii.

I have a button in the page. I need to set a session variable when user clicks it and get the session value when user clicks on another button.

How can I do that?

Answer 1

Use CWebUser state methods

//set session variable
Yii::app()->user->setState("state_name", "value");

//check session variables
Yii::app()->user->hasState("state_name");

//get session variable
Yii::app()->user->getState("state_name");

//delete session variable (thanks @Kailas)
Yii::app()->user->setState("state_name", null);
