I've searched a lot on the net how to access the global $_SESSION
array from TWIG template and found this: {{app.session.get('index')}}
, but when I'm calling it, it returns an empty string. I have a $_SESSION['filter']['accounts']
and I'm getting this error when calling {{app.session.get('filter').accounts}}
: Item "accounts" for "" does not exist
. What I'm doing wrong?
{{app.session}}
refers to the Session
object and not the $_SESSION
array. I don't think the $_SESSION
array is accessible unless you explicitly pass it to every Twig template or if you do an extension that makes it available.
Symfony2 is object-oriented, so you should use the Session
object to set session attributes and not rely on the array. The Session
object will abstract this stuff away from you so it is easier to, say, store the session in a database because storing the session variable is hidden from you.
So, set your attribute in the session and retrieve the value in your twig template by using the Session
object.
// In a controller
$session = $this->get('session');
$session->set('filter', array(
'accounts' => 'value',
));
// In Twig
{% set filter = app.session.get('filter') %}
{% set account-filter = filter['accounts'] %}
Hope this helps.
