• Using get to retrieve flash messages now returns an array.

  Retrieving the flash messages from a Twig template

  Before:

  {% if app.session.hasFlash('notice') %}
    <div class="flash-notice">
        {{ app.session.getFlash('notice') }}
    </div>
  {% endif %}

  After:

  {% for flashMessage in app.session.flashbag.get('notice') %}
    <div class="flash-notice">
        {{ flashMessage }}
    </div>
  {% endfor %}

  You can process all flash messages in a single loop with:

  {% for type, flashMessages in app.session.flashbag.all() %}
    {% for flashMessage in flashMessages %}
        <div class="flash-{{ type }}">
            {{ flashMessage }}
        </div>
    {% endfor %}
  {% endfor %}
