Set session in Yii framework

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

Simple

Yii::app()->session['var'] = $encrypted_txt;

Answer 2

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);

Answer 3

you can use CWebUser's setState.

Yii::app()->user->setState('key', 'value');

Answer 4

$session = Yii::$app->session;

// get a session variable. The following usages are equivalent:

$language = $session->get('language');

// set a session variable. The following usages are equivalent:

$session->set('language', 'en-US');

// remove a session variable. The following usages are equivalent:

$session->remove('language');

// check if a session variable exists. The following usages are equivalent:

if ($session->has('language'))
