Why doesn't submit work?

Question

Yii

The form:

<?php
$form = ActiveForm::begin();
?>
<?= Html::submitButton(Yii::t('app', 'Remove'), ['class' => 'btn btn-primary']) ?>
<?php ActiveForm::end() ?>

Controller:

$md = new MdbUsers();
if($md->load(\Yii::$app->request->post())) {
$this->redirect('/');
}

Actually, why doesn't the redirect work?

Answer 1

return $this->redirect('/');
