Yii2: Yii::$app->getResponse()->redirect() and flash message

[ageusz]

I need to set a flash and then get the Response object of another action and return it. So I made a simple test - created whole new Yii2 project and added following to site/index action:

Yii::$app->getSession()->setFlash('error', 'bad error');
return Yii::$app->getResponse()->redirect('site/about');

Flash not visible, but when I changed to:

Yii::$app->getSession()->setFlash('error', 'bad error');
return $this->redirect('site/about');

flash message is visible.
How can I return Response object of another action and still keep the flash on?

Unable to reproduce this issue. With plain basic application it is working in both cases.

Same here.

I was using advanced application but I'm not sure how it could be relevant. Maybe the issue is caused by WAMP server... I'll post solution if I find it.

I have same issue too. I occur in the following cases:

namespace app\helpers;

use Yii;
use yii\helpers\Url;

trait Web
{
    public function save($model, $message)
    {
        if ($model->load(Yii::$app->request->post()) && $model->save()) {
            Yii::$app->session->setFlash('success', $message);
            return Yii::$app->response->redirect(Url::to(['view', 'id' => $model->id]));
        }
    }
}

Controller:

namespace app\controllers;

use yii\web\Controller;
use app\helpers\Web;

class PostController extends Controller
{
    use Web;

    public function actionCreate()
    {
        $post = new Post;
        $this->save($post, 'success!');

        return $this->render('create', compact('post'));
    }
}

In layout view I use the Alert widget .

Same issue. Flash works in my localhost, but does not work in my linux server.
Edit: It seems to be an issue with redirect. If your initial redirect gets redirected again, the message is lost. I saw a 302 redirect in the URL that had this issue. This somehow got fixed in my case.

Same issue, It works for me if in the controller I add a return in the same line to call the trait method, but it isn't a good solution for me because I only need return case of error.

Any other solution?

I have a solution

if(Yii::$app->getResponse()->getStatusCode() != 302) {
    Yii::$app->session->getFlash('error');
}

Guys this one got solved for me many days ago lol. DO NOT call $this->redirect($path) with out a return.

Correct code is:

      Yii::$app->session->setFlash('success', Some Message.');
       return $this->redirect(['path']);

    Yii::$app->getSession()->setFlash('error', 'bad error');
    Yii::$app->getResponse()->redirect(['site/about']);
    Yii::$app->getResponse()->send();
    exit;

I also have similar issue, and just realized that I can not use another function to redirect.

NOT working:

public function actionApply()
{
    $items = $post['items'];
    $this->checkRequirements($items);

}

private function checkRequirements($items)
    {
        if (count($items) > static::MAX_ITEM)
        {
            Yii::$app->session->setFlash('error', 'Number of items can not exceed ' . static::MAX_ITEM);
            return $this->redirect('/reimburse/apply/');
        }
    }

Works :

public function actionApply()
{
    $items = $post['items'];
            if (count($items) > static::MAX_ITEM)
        {
            Yii::$app->session->setFlash('error', 'Number of items can not exceed ' . static::MAX_ITEM);
            return $this->redirect('/reimburse/apply/');
        }
// more action.... 
}

I have the same issue, and only the solution of @Mirocow worked for me without the "return" keyword.
Is that the correct way?
