How to Access the User, Request, Session & more in Twig via the app Variable¶
During each request, Symfony will set a global template variable app
in both Twig and PHP template engines by default. The app variable
is a AppVariable
instance which will give you access to some application specific variables
automatically:
app.user- The representation of the current user or
nullif there is none. The value stored in this variable can be aUserInterfaceobject, any other object which implements a__toString()method or even a regular string. app.request- The
Requestobject that represents the current request (depending on your application, this can be a sub-request or a regular request, as explained later). app.session- The
Sessionobject that represents the current user's session ornullif there is none. app.environment- The name of the current environment (
dev,prod, etc). app.debug- True if in debug mode. False otherwise.
1 2 3 4 5 | <p>Username: {{ app.user.username }}</p>
{% if app.debug %}
<p>Request method: {{ app.request.method }}</p>
<p>Application Environment: {{ app.environment }}</p>
{% endif %}

You can add your own global template variables, see How to Inject Variables into all Templates (i.e. global Variables).
