Sorry for my English, but what I'm trying to say is explained below.
I have a controller say ControllerCard which has an action like this.
function actionScanCard()
{
...
$this->redirect('/transaction/redeem');
...
}
In other controllers, ControllerTransaction, I am trying to get that it comes/redirected from /card/scan-card
function actionRedeem()
{
$redirectFrom = ????;
if ($redirectFrom === '/card/scan-card')
{
// some actions
}
else
throw new ForbiddenHttpException('Must scan card!');
}
How do I get this $redirectFrom value with Yii2?
对不起我的英语，但我想说的是下面的解释。 \ n
我有一个控制器说 在其他控制器中， 如何使用Yii2获取此 ControllerCard ，它有这样的动作。
function actionScanCard（）
{
...
$ this-＆gt; redirect（'/ transaction / redeem'）;
...
}
ControllerTransaction ，我试图让它来自 / card / scan-card
function actionRedeem（）
{
$ redirectFrom = ????;
if（$ redirectFrom ==='/ card / scan-card'）
{
//某些动作
}
否则
抛出新的ForbiddenHttpException（' 必须扫描卡！'）;
}
$ redirectFrom 值？ \ n
