Question

I’m using Silex, and I’m wondering if it is possible to use an associative array for a flash session variable? I can’t seem to get it to work.

Here’s what I’ve been trying:

Setting up the flash var in my app file.

$my_array = array('fruit' => 'apple', 'veggie' => 'carrot');
$app['session']->setFlash('myFlashVar', $my_array);

And used in Twig like this.

{% set myVar = app.session.getFlash('myFlashVar') %}
// And so that we don't get an error, check to see if the key exists
{% if 'fruit' in myVar|keys  %}{{ myVar['fruit'] }}{% endif %}

Thanks in advance for any help offered.

Answer 1

setFlash and getFlash a deprecated methods and therefore should be avoided.

You can get your code to run by using the favored methods provided by Session::getFlashBag (pun intended?)

PHP:

$my_array = array('fruit' => 'apple', 'veggie' => 'carrot');
$app['session']->getFlashBag()->set('myFlashVar', $my_array);

TWIG:

{% for flashMessage in app.session.flashbag.get('myFlashVar') %}

    {{ flashMessage }}

{% endfor %}

Disclaimer: I only tested this using the Symfony2 (2.16) framework – not Silex. In Symfony2 it is:

$this->get('session')->getFlashBag()->set('myFlashVar', $my_array);
