问题
I am developing an application using Symfony2. I am using Twig for templating an a 3 level interface architecture. In my application there are 3 kind of users, anonimous users, udentified users and Administrators. The Page is divided in sections this way:
<!-- app/Resources/views/base.html.twig -->
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=utf-8" />
<title>{% block title %}Anotatzailea{% endblock %} - Anotatzailea</title>
<!--[if lt IE 9]>
<script src="http://html5shim.googlecode.com/svn/trunk/html5.js"></script>
<![endif]-->
{% block stylesheets %}
<link href='http://fonts.googleapis.com/css?family=Voces' rel='stylesheet' type='text/css'>
<link href='http://fonts.googleapis.com/css?family=La+Belle+Aurore' rel='stylesheet' type='text/css'>
<link href="{{ asset('css/screen.css') }}" type="text/css" rel="stylesheet" />
{% endblock %}
<link rel="shortcut icon" href="{{ asset('favicon.ico') }}" />
</head>
<body>
<section id="wrapper">
<header id="header">
<div id="logo">
<text>Anotatzailea</text>
</div>
<div class="top">
{% block navigation %}
{# Ikusi behar da ea erabiltzailea kautotu den, horren arabera aukera desberdinak erakusteko #}
{% if is_granted('ROLE_USER') %}
<nav>
<ul class="navigation">

{% else %}

</section>
{% block javascripts %}

</body>
</html>
What I would like to do is to show the sidebar just when the identified users are logged in the application. The way I do it I just achieve not show the sidebar for anonymous users. The other problem is I don't know how to make the main-col section bigger so that the gap left by the sidebar can not be seen.
回答1:
I think you can get what you need to,easily by applying the condictions as
{% if is_granted('ROLE_USER') or is_granted('ROLE_ADMIN') %}
<section class="main-col">
{%else%}
<section class="main-col">
{# modify the class of this section as your requirement #}
{%endif%}
{% block body %}{% endblock %}
</section>
{% if is_granted('ROLE_USER') or is_granted('ROLE_ADMIN') %}
<section class="sidebar">
{% block sidebar %}{% endblock %}
</section>
{%endif%}
hope this helps
