Yii2 - flash not visible after redirect
Flash messages seems to be broken in case of redirecting. I made simple test code:
public function actionTest($test = 0) {
if($test == 0) {
Yii::$app->getSession()->addFlash('success', 'Follow the white rabbit');
return Yii::$app->getResponse()->redirect(array('test', 'test' => 1));
}
return $this->render('test', []);
}
I call the action without parameter, it adds a flash and redirects. When it renders the page - flash is not present.
The view part is fine, because if I set flash and make a render without redirect it is rendered properly.
Why?
EDIT: Layout view code:
<?php
use frontend\widgets\Alert;
$this->beginPage();
echo $this->render('partials/head');
?>
<body class="no-sidebar">
<?= $this->beginBody() ?>
<div id="header">
<?= $this->render('partials/top') ?>
<?= $this->render(Yii::$app->user->isGuest ? 'menus/guest' : 'menus/registered') ?>
</div>
<!-- Main -->
<div id="main">
<?= Alert::widget() ?>
<?= $content ?>
</div>
<?= $this->render('partials/footer') ?>
<?= $this->endBody() ?>
</body>
</html>
<?php $this->endPage() ?>
Answer
I've gotten the same error until I found out that the return is missing in my code. So, with return $this->redirect() it works just fine and with $this->redirect it does not work well.
