{# This is a template fragment designed to be included in other templates See https://symfony.com/doc/current/book/templating.html#including-other-templates A common practice to better distinguish between templates and fragments is to prefix fragments with an underscore. That's why this template is called '_flash_messages.html.twig' instead of 'flash_messages.html.twig' #} {# The request method check is needed to prevent starting the session when looking for "flash messages": https://symfony.com/doc/current/session/avoid_session_start.html TIP: With FOSHttpCache you can also adapt this to make it cache safe: https://foshttpcachebundle.readthedocs.io/en/latest/features/helpers/flash-message.html #} {% if app.request.hasPreviousSession %}
