Answer 1

simply use referrer.
return $this->redirect(Yii::$app->request->referrer)
If it has no referrer or link open directly then you should either pass computer_id as param or you must have computer_id as foreign key in your review table.
Let say you have relationship with review and computer table. then you can use like this.
$compId = $comment->computer_id; // or 15 or you can paas param here
return $this->redirect(["comp/computer", "id"=> $compId]);
if comp is your hostname then
return $this->redirect(["computer", "id"=> $compId]);
its should be controller/action
return $this->redirect(["controllerId/actionId", "id"=> $compId]);
Send via mobile, sorry for typos.
