This plugin allows you to use the Twig Templating Language for your views.
In addition to enabling the use of most of Twig's features, the plugin is tightly integrated with the CakePHP view renderer giving you full access to helpers, objects and elements.
To install via Composer, use the command below.
composer require wyrihaximus/twig-viewRun the following CLI command:
bin/cake plugin load WyriHaximus/TwigViewInstead of extending from the View let AppView extend TwigView:
namespace App\View;
use WyriHaximus\TwigView\View\TwigView;
class AppView extends TwigView
{
}TwigView will look for its templates with the extension .twig.
Replace templates/layout/default.php by this templates/layout/default.twig
<!DOCTYPE html>
<html>
<head>
{{ Html.charset()|raw }}
<title>
{{ __('myTwigExample') }}
{{ _view.fetch('title')|raw }}
</title>
{{ Html.meta('icon')|raw }}
{{ Html.css('default.app.css')|raw }}
{{ Html.script('app')|raw }}
{{ _view.fetch('meta')|raw }}
{{ _view.fetch('css')|raw }}
{{ _view.fetch('script')|raw }}
</head>
<body>
<header>
{{ _view.fetch('header')|raw }}
</header>
{{ Flash.render()|raw }}
<section>
<h1>{{ _view.fetch('title')|raw }}</h1>
{{ _view.fetch('content')|raw }}
</section>
<footer>
{{ _view.fetch('footer')|raw }}
</footer>
</body>
</html>Create a template, for example templates/Users/index.twig like this
{{ _view.assign('title', __("I'm title")) }}
{{ _view.start('header') }}
<p>I'm header</p>
{{ _view.end() }}
{{ _view.start('footer') }}
<p>I'm footer</p>
{{ _view.end() }}
<p>I'm content</p>With twig $this is replaced by _view
For example, without using Twig writing
<?= $this->fetch('content') ?>But with Twig
{{ _view.fetch('content')|raw }}Any helper can be access by their CamelCase name, for example:
{{ Html.link('Edit user', {'controller':'Users', 'action': 'edit' ~ '/' ~ user.id}, {'class':'myclass'})|raw }}Basic
{% element 'Element' %}With variables or options
{% element 'Plugin.Element' {
dataName: 'dataValue'
} {
optionName: 'optionValue'
} %}Store in context then echo it
{% cell cellObject = 'Plugin.Cell' {
dataName: 'dataValue'
} {
optionName: 'optionValue'
} %}
{{ cellObject|raw }}Fetch and directly echo it
{% cell 'Plugin.Cell' {
dataName: 'dataValue'
} {
optionName: 'optionValue'
} %}If i want extend to Common/demo.twig
<div id="sidebar">
{% block sidebar %}{% endblock %}
</div>
<div id="content">
{% block body %}{% endblock %}
</div>We can write in a view
{% extends 'Common/demo' %}
{% block sidebar %}
<ul>
<li>Item 1</li>
<li>Item 2</li>
<li>Item 3</li>
</ul>
{% endblock %}
{% block body %}
{{ _view.assign('title', __("I'm title")) }}
{{ _view.start('header') }}
<p>I'm header</p>
{{ _view.end() }}
{{ _view.start('footer') }}
<p>I'm footer</p>
{{ _view.end() }}
<p>I'm content</p>
{% endblock %}Note : the block body is required, it's equivalent to <?= $this->fetch('content') ?>

This plugin emits several events.
The default loader can be replace by listening to the WyriHaximus\TwigView\Event\LoaderEvent::EVENT, for example with twital:
<?php
use Cake\Event\EventListenerInterface;
use Goetas\Twital\TwitalLoader;
use WyriHaximus\TwigView\Event\ConstructEvent;
use WyriHaximus\TwigView\Event\LoaderEvent;
class LoaderListener implements EventListenerInterface
{
public function implementedEvents(): array
{
return [
LoaderEvent::EVENT => 'loader',
ConstructEvent::EVENT => 'construct',
];
}
public function loader(LoaderEvent $event): void
{
$event->result = new TwitalLoader($event->getLoader());
}
/**
* We've also listening in on this event so we can add the needed extensions to check for to the view
*/
public function construct(ConstructEvent $event): void
{
$event->getTwigView()->unshiftExtension('.twital.html');
$event->getTwigView()->unshiftExtension('.twital.xml');
$event->getTwigView()->unshiftExtension('.twital.xhtml');
}
}
Extensions can be added to the twig environment by listening to the WyriHaximus\TwigView\Event\ConstructEvent::EVENT, for example:
<?php
use Cake\Event\EventListenerInterface;
use WyriHaximus\TwigView\Event\ConstructEvent;
class LoaderListener implements EventListenerInterface
{
public function implementedEvents(): array
{
return [
ConstructEvent::EVENT => 'construct',
];
}
public function construct(ConstructEvent $event): void
{
$event->getTwig()->addExtension(new YourTwigExtension);
}
}You can use Bake to generate your basic CRUD views using the theme option.
Let's say you have a TasksController for which you want to generate twig templates.
You can use the following command to generate your index, add, edit and view file formatted
using Twig :
bin/cake bake twig_template Tasks all -t WyriHaximus/TwigView
