Silex: Redirect with Flash Data

Yes, FlashBag is the right way.Set a flash message in your controller (you can add multiple messages):

$app['session']->getFlashBag()->add('message', 'text');$app->redirect('/here', 301)

And print it in the template:

{% for message in app.session.getFlashBag.get('message') %}    {{ message }}{% endfor %}

I created this simple FlashBagTrait that may be of use:

<?phpuse Symfony\Component\HttpFoundation\Session\Flash\FlashBagInterface;trait FlashBagTrait{    /**     * @return FlashBagInterface     */    public function getFlashBag() {        return $this['session']->getFlashBag();    }}

Just add it to your Application class and it will make things ever-so-slightly easier!

$app->getFlashBag()->add('message',array('type'=>"danger",'content'=>"You shouldn't be here"));{% if app.flashbag.peek('message') %}<div class="row">    {% for flash in app.flashbag.get('message') %}        <div class="bs-callout bs-callout-{{ flash.type }}">            <p>{{ flash.content }}</p>        </div>    {% endfor %}</div>{% endif %}

Its main advantage is that type-hinting will work in PhpStorm.

You can also add it as a service provider,

$app['flashbag'] = $app->share(function (Application $app) {    return $app['session']->getFlashBag();});

Which makes it more convenient to use from PHP (but you lose the type-hinting):

$app['flashbag']->add('message',array('type'=>"danger",'content'=>"You shouldn't be here"));
