Yii2 Solutions
Solution 1 - Yii2
You could use Yii::$app->request->referrer which returns the last page the user was on.
Usage is straightforward:
return $this->redirect(Yii::$app->request->referrer);
You need also take into account that referrer can be null:
return $this->redirect(Yii::$app->request->referrer ?: Yii::$app->homeUrl);
See the docs.
Solution 2 - Yii2
Here it says that it's a good practice to check if referrer is set at the first place.
So if you use the following code you will be redirected to last page if referrer is set or to your configured homeUrl if the return URL was not set previously.
return $this->goBack((!empty(Yii::$app->request->referrer) ? Yii::$app->request->referrer : null));
Solution 3 - Yii2
It is true what @Kostas says, but I think it would be better if you simply code the following, because goBack take account of a null parameter already to goBack HOME.
return $this->goBack(Yii::$app->request->referrer);
I tested it and it works fine.
Solution 4 - Yii2
If you use Html::submitButton when you are in a form and you want to be redirected to the previous page, so mostly to your module list I recommend using use yii\helpers\Url;:
return $this->redirect(Url::previous('previous') ?: ['list']);
because
return $this->redirect(Yii::$app->request->referrer);
will return you back to the form instead of a module list.
