Accessing the logged-in user in a template
You can access user data directly in the twig template without requesting anything in the controller. The user is accessible like that : app.user.
Now, you can access every property of the user. For example, you can access the username like that : app.user.username.
Warning, if the user is not logged, the app.user is null.
If you want to check if the user is logged, you can use the is_granted twig function. For example, if you want to check if the user has ROLE_ADMIN, you just have to do is_granted("ROLE_ADMIN").
So, in every of your pages you can do :
{% if is_granted("ROLE") %} Hi {{ app.user.username }}{% endif %}
For symfony 2.6 and above we can use
{{ app.user.getFirstname() }}as app.security global variable for Twig template has been deprecated and will be removed from 3.0

{{ app.user.username|default('') }}Just present login username for example, filter function default('') should be nice when user is NOT login by just avoid annoying error message.
