Twig Plugin for Kirby CMS

• Adds support for Twig templates to Kirby CMS 2.x.
• PHP templates still work, you don’t have to rewrite them if you don’t want to.

What it looks like

Before:

<?php /* site/templates/hello.php */ ?>
<h1><?= $page->title() ?></h1>
<ul>
<?php foreach ($page->children() as $child): ?>
  <li><a href="https://github.com/fvsch/kirby-twig/blob/main/<?= $child->url() ?>"><?= $child->title() ?></li>
<?php endforeach; ?>
</ul>

After:

{# site/templates/hello.twig #}
<h1>{{ page.title }}</h1>
<ul>
{% for child in page.children %}
  <li><a href="https://github.com/fvsch/kirby-twig/blob/main/{{ child.url }}">{{ child.title }}</li>
{% endfor %}
</ul>

Installation

Standard installation

1. Download the latest release.
2. Unzip, rename the kirby-twig-main folder to just twig and put it in your project’s site/plugins folder.

You should end up with a folder structure like this:

site
 └─ plugins
     └─ twig
         ├─ lib
         ├─ src
         └─ twig.php

Using Composer

Require fvsch/kirby-twig in your Composer dependencies:

composer require fvsch/kirby-twig:^3.0

Then, make sure your Kirby installation is autoloading Composer dependencies on both frontend and panel. For this, the safest way is to create your own custom plugin.

site
 └─ plugins
     └─ composer
         └─ composer.php

<?php
// site/plugins/composer/composer.php

// Composer autoload
require_once kirby()->roots()->index() . '/vendor/autoload.php';

Finally, register the plugin by adding this line to your newly created site/plugins/composer/composer.php, after having required the autoloader.

// Register the Twig plugin's template component
Kirby\Twig\Plugin::register();

Usage

Page templates

Now that the plugin is installed and active, you can write Twig templates in the site/templates directory. For example, if the text file for your articles is named post.txt, you could have a post.twig template like this:

{% extends '@templates/layout.twig' %}
{% block content %}
  <article>
    <h1>{{ page.title }}</h1>
    {{ page.text.kirbytext | raw }}
  </article>
{% endblock %}

See the {% extends '@templates/layout.twig' %} and {% block content %} parts? They’re a powerful way to manage having a common page layout for many templates, and only changing the core content (and/or other specific parts). Read our Twig templating guide for more information.

Rendering a template in PHP: the twig helper

This plugin also enables a twig PHP function for rendering template files and strings, like this:

<?php

// Render a simple template from the site/snippets directory
echo twig('@snippets/header.twig');

// Same, but passing some additionnal variables
echo twig('@snippets/header.twig', ['sticky'=>false]);

// Render a string
echo twig('Hello {{ who }}', ['who'=>'World!']);

If you work with Twig templates for pages, you might not need the twig() helper at all. But it can be useful when working with the Modules and Patterns plugins.
