取消设置Twig会话变量

Question

How can we destroy the session variable in twig? I can get session variables by app.session.get('$name'). And I want to destroy it afterwards for some purposes.

Thanx!

Flash Messages are the right way to do this.

Symfony2 Cookbook example:

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

For more information check the Symfony documentation flash messages .
