Mastering Symfony

Overview of this book

In this book, you will learn some lesser known aspects of development with Symfony, and you will see how to use Symfony as a framework to create reliable and effective applications. You might have developed some impressive PHP libraries in other projects, but what is the point when your library is tied to one particular project? With Symfony, you can turn your code into a service and reuse it in other projects. This book starts with Symfony concepts such as bundles, routing, twig, doctrine, and more, taking you through the request/response life cycle. You will then proceed to set up development, test, and deployment environments in AWS. Then you will create reliable projects using Behat and Mink, and design business logic, cover authentication, and authorization steps in a security checking process. You will be walked through concepts such as DependencyInjection, service containers, and services, and go through steps to create customized commands for Symfony's console. Finally, the book covers performance optimization and the use of Varnish and Memcached in our project, and you are treated with the creation of database agnostic bundles and best practices.

Dynamic templates and controllers


Now that we have a few records in our table, let's see how to fetch them via controller and feed their properties to our templates. What we expect from our dynamic template is to receive an object and show its properties. In our case, the object is User and its properties are name, bio, and email. So, edit the about/index.html.twig template as follows:

{# mava/app/Resources/views/about/index.html.twig #}

{% if user %}
  <h1>User Profile</h1>
  <strong>Name: </strong>{{user.name}} <br/>
  <strong>email: </strong>{{user.email}} <br/>
  <strong>Bio: </strong>{{user.bio}} <br/>
{% else %}
  mava is a web app for task management and team collaboration. <br/>
{% endif %}

Next, add a few lines to aboutAction() to retrieve information about the given user:

<?php
// AppBundle/Controller/DefaultController.php
// …
use AppBundle\Entity\User;
// ...
  /**
   * @Route("/about/{name}", name="aboutpage...
