Magento 2 Twig Template Engine

Twig template engine for Magento2.

This template engine is meant to be used additionally to the .phtml files and does not provide any .twig template file.

A use case would be if you write your first Magento2 module you can require this package and write all your template files in Twig.

Installation

1. Add dependency

composer require schumacherfm/magento-twig

2. Enable the module

bin/magento module:enable SchumacherFM_Twig

3. Update the database entries

bin/magento setup:upgrade

Events & Configuration

The Twig template engine class dispatches two events so that you can modify Twig.

Event twig_loader with event object loader. You can set loader any other class which implements Twig_LoaderInterface. http://twig.sensiolabs.org/doc/api.html#loaders

Event twig_init with event object twig. You can add here more functions, filters, tags, etc. http://twig.sensiolabs.org/doc/advanced.html

Configuration options can be found Stores -> Settings -> Configuration -> Advanced -> Developer -> Twig.

Frontend Integration

Your template files must have the file extension .twig to get automatically recognized.

In your layout xml files or blocks please specify the new template

<referenceBlock name="top.links">
    <block class="Magento\Theme\Block\Html\Header" template="html/header.twig" name="header" as="header" before="-">
        <arguments>
            <argument name="show_part" xsi:type="string">welcome</argument>
        </arguments>
    </block>
</referenceBlock>

Example header.phtml converted to header.twig

<?php switch ($this->getShowPart()):
    case 'welcome': ?>
        <li class="greet welcome"><?php echo $this->getWelcome() ?></li>
    <?php break; ?>
    <?php case 'other': ?>
        <?php echo $this->getChildHtml(); ?>
    <?php break; ?>
<?php endswitch; ?>

{% if getShowPart() == 'welcome' %}
    <li class="greet welcome">{{ getWelcome() }}</li>
{% endif %}

{% if getShowPart() == 'other' %}
    {{ getChildHtml()|raw }}
{% endif %}

Example breadcrumbs.phtml converted to breadcrumbs.twig

<?php if ($crumbs && is_array($crumbs)) : ?>
<div class="breadcrumbs">
    <ul class="items">
        <?php foreach ($crumbs as $crumbName => $crumbInfo) : ?>
            <li class="item <?php echo $crumbName ?>">
            <?php if ($crumbInfo['link']) : ?>
                <a href="<?php echo $crumbInfo['link'] ?>" title="<?php echo $this->escapeHtml($crumbInfo['title']) ?>">
                    <?php echo $this->escapeHtml($crumbInfo['label']) ?>
                </a>
            <?php elseif ($crumbInfo['last']) : ?>
                <strong><?php echo $this->escapeHtml($crumbInfo['label']) ?></strong>
            <?php else: ?>
                <?php echo $this->escapeHtml($crumbInfo['label']) ?>
            <?php endif; ?>
            </li>
        <?php endforeach; ?>
    </ul>
</div>
<?php endif; ?>

{% if crumbs %}
<div class="breadcrumbs">
    <ul class="items">
    {% for crumbName,crumbInfo in crumbs %}
        <li class="item {{ crumbName }}">
            {% if crumbInfo.link %}
                <a href="{{ crumbInfo.link }}" title="{{ crumbInfo.title }}">
                    {{ crumbInfo.label }}
                </a>
            {% elseif crumbInfo.last %}
                <strong>{{ crumbInfo.label }}</strong>
            {% else %}
                {{ crumbInfo.label }}
            {% endif %}
        </li>
    {% endfor %}
    </ul>
</div>
{% endif %}
