#Twig templates for SilverStripe 3.1
##Overview
SilverStripe Twig enables the use of the Twig templating engine in SilverStripe 3.1.
If you are not familiar with Twig, check out the docs.
##Installation
###Composer
Create or edit a composer.json
file in the root of your SilverStripe project, and make sure the following is present.
{ "require": { "camspiers/silverstripe-twig": "0.0.*", "camspiers/autoloader-composer-silverstripe": "1.0.*" } }
After completing this step, navigate in Terminal or similar to the SilverStripe root directory and run composer install
or composer update
depending on whether or not you have composer already in use.
##Getting started
###What to name and where to put your templates
Create a folder called twig
in your current theme. This is where twig will look for your templates. By default Twig expects your templates to be named with the .twig
extension, but can be easily configured to look for others (see twig.extensions
).
The way SilverStripe twig decides which template to use is the same way SilverStripe selects .ss
templates.
It builds a ranked list of candidate templates based on the class name of the current controller or dataRecord and the action being called. Using the template list it selects the first template that it finds.
For example, for page of PageType Page
. If there is a Page.twig
template in the twig folder it will use that.
###How to enable twig
Twig rendering is enabled by extending the functionality of your SilverStripe controller. This can be done in two ways depending on what version of PHP you have.
####PHP 5.3
If you want to use twig for all controllers that extend Page_Controller
, set up is as follows:
Page.php
class Page_Controller extends TwigContentController { }
If you want to use twig in a Controller
, set up is as follows:
MyController.php
class MyController extends TwigController { }
####PHP 5.4
The PHP 5.3 classes above are actually auto-generated from a trait. To use the trait add a use
statement in your controller as follows:
class Page_Controller extends ContentController { use TwigControllerTrait; }
or:
class MyController extends Controller { use TwigControllerTrait; }
###Accessing your Controller in twig
By default twig makes your controller (and therefore your dataRecord) available in your template by the variable c
.
{% for Page in c.Pages %} {{ Page.Title }} {% endfor %}
<title>{{ c.Title }}</title>
<ul> {% for Page in c.Menu(1) %} <li>{{ Page.Title }}</li> {% else %} <li>No pages</li> {% endfor %} </ul>
###Practical usage example
Achieving similar functionality to SilverStripe's $Layout
variable is easy with twig.
Twig has the concepts of extends
and blocks
which enable flexible template reuse.
Page.twig
{% extends "layouts/layout.twig" %} {% block head %} {{ parent() }} {# add some extra assets here #} {% endblock %} {% block header %} {# add some header content here #} {% endblock %} {% block content %} <h1>{{ c.Title }}</h1> {% endblock %}
layouts/layout.twig
<html> <head> {% block head %} {# default assets here #} {% endblock %} </head> <body> {% block header %}{% endblock %} {% block content %}{% endblock %} </body> </html>
###Configuration
SilverStripe Twig uses a dependency injection container (an extension of Pimple
) to allow configuration and DI for all objects used.
Options
- twig.environment_options
- twig.extensions
- twig.compilation_cache
- twig.template_paths
- twig.controller_variable_name
An example:
mysite/_config.php
TwigContainer::extendConfig(array( 'twig.environment_options' => array( 'debug' => true ), 'twig.extensions' => array( '.twig', '.html' ), 'twig.compilation_cache' => BASE_PATH . '/silverstripe-cache', 'twig.template_paths' => array( THEMES_PATH . '/my-theme/templates' ), 'twig.controller_variable_name' => 'controller' ));
Any service provided by SilverStripe Twig can be accessed by instantiating the Container.
$dic = new TwigContainer; $dic['twig']->loadTemplate('template.twig')->render();
See Pimple for more information.
##Using Twig and Haml together SilverStripe twig supports the use of haml through the SilverStripe haml module.
Install the SilverStripe haml module and you are ready to go.
You can now name your files .haml
(though you don't have to).
###Usage
To get Twig to process your file as Haml
add:
{% haml %}
To the top of any template you want to be processed as haml.
Example:
{% haml %} !!! %html %head %title #{ c.Title } | haml and twig - block head :javascript console.log('yay'); %body - block content %h1 #{ c.Title } %p #{ c.Content|raw } %span.created #{ c.Created|date("d/m/Y") }
