Symfony 2 - instalacja przez Composera - ogólny opis architektury - Bundle - najważniejszy element architektury

1. Symfony 2 – why ?
- Framework separated from our code
- Everything is a bundle
- Composer to rule them all
- Lots of useful bundles
- Documentation
- Flexibility

2. What is a bundle ?
● A bundle is simply a structured set of files within a
directory that implement a single feature.
● Each directory contains everything related to that
feature, including PHP files, templates,
stylesheets, JavaScripts, tests and anything else.
● There is always 'but'. Common parts place out of
bundle.
● App specific bundles are interdependent

3. Core bricks
● Symfony 2
● Doctrine 2
● TWIG
● Your code

4. Symfony 2 - requirements
● PHP 5.3.3+
● PHP 5.4.0 – for build in server
● Composer
● MySql

5. Symfony 2 - installation
● Manual – full
● Manual – base only
● Composer
composer create-project symfony/framework-standard-edition myproject/ ~2.5
● Check what is missing
php app/check.php

6. Symfony 2 – installation
● Document root
● Cache and logs directory
● Run developer server (PHP 5.4.0+)
php app/console server:run
● Visit config.php

7. Symfony 2 – directory structure
● App
● Bin
● Src
● Vendor
● Web

8. Symfony 2 - environments
● Develop
app_dev.php
● Production

9. Symfony 2 – The Bundle
● Create new bundle - interactive
php app/console generate:bundle
● Create new bundle – one command
●

10. Symfony 2 – The Routing
● Simple route
articlebundle_article_top5:
path: /articles/top5
defaults: { _controller: DvsArticleBundle:Default:top5 }
● Advanced route
articlebundle_article_list:
path: /articles/{page}
defaults: { _controller: DvsArticleBundle:Default:list, page:1 }
methods: [GET]
requirements:
page: d+

11. Symfony 2 – The Routing II
● Routes list
php app/console router:debug
● Receive params in controller as list
indexAction($category, $page) – order doesnt matter
● Receive params in controller as Request object
indexAction(Request $request)
$request->query->get('page')
$request->request->get('page')
