You can only pass GET parameters in the Yii 2 redirect(). However, I had a similar situation and I resolved it by using Session storage.

Naturally, you can access current Session via Yii::$app->session. Here is an example of using it in two separate controller actions:

public function actionOne() {
    // Check if the Session is Open, and Open it if it isn't Open already
    if (!Yii::$app->session->getIsActive()) {
        Yii::$app->session->open();
    }
    Yii::$app->session['someParameter'] = 'Bool/String/Array...';
    Yii::$app->session->close();
    $this->redirect(['site/two']);
}

public function actionTwo() {
    if (isset(Yii::$app->session['someParameter']) {
       $param = Yii::$app->session['someParameter'];
    } else {
       $param = null;
    }
    $this->render('two', [
        'param' => $param
    ]);
}

So now you should be able to access $param inside the two view.
