README

This module use Twig template engine as parser for Thelia and replace Smarty.

This module is not stable and is still in development. See the RoadMap if you want to know which features are missing

###Summary :

Installation

You can only install this module with composer :

$ composer require thelia/twig-module:dev-master

Activation

It is required to enable this module with the cli tools and then disable TheliaSmarty module :

$ php Thelia module:refresh
$ php Thelia module:activate TheliaTwig
$ php Thelia module:deactivate TheliaSmarty

Usage

Template files must be suffixed by .twig, for example index.html.twig

The template structure is the same as the actual structure, so you can referer to the actual documentation

You can test the module with this module : https://github.com/bibich/TheliaTwigTest

Syntax

Loop

loop feature is a Twig tag, you have to use it like a block. All loop's parameters use literals syntax and are the same as the acutal parameters. The tag start with loop and finish with endloop

example :

<ul>
{% loop {type:"category", name:"cat", limit:"2"} %}
    <li>{{ ID }} : {{ TITLE }}
        <ul>
    {% loop {type:"product", name:"prod", category: ID} %}
        <li>Title : {{ TITLE }} </li>
    {% endloop %}
        </ul>
    </li>
{% endloop %}
</ul>

Conditional loop

Conditional loops are implemented. As for Smarty a ifloop can wrap a loop and can be used after the related loop. elseloop must be used after the related loop

{% ifloop {rel:"cat"} %}
    <p>Before categories</p>
    <ul>
    {% loop {type:"category", name:"cat", limit:"2"} %}
        <li>{{ ID }} : {{ TITLE }}
            <ul>
        {% loop {type:"product", name:"prod", category: ID} %}
            <li>Title : {{ TITLE }} </li>
        {% endloop %}
            </ul>
        </li>
    {% endloop %}
    </ul>
<p>After categories</p>
{% endifloop %}
{% elseloop {rel:"cat"} %}
    <p>there is no category</p>
{% endelseloop %}

Paginated loop

Paginated loop works exactly like paginated loop for Smarty, just the syntax change. See the official documentation for all parameters : http://doc.thelia.net/en/documentation/loop/index.html#page-loop

Syntax example :

<p>Products Loop</p>
<ul>
{% loop {type:"product", name:"pagination", limit:"5", page:"3"} %}
    <li>{{ TITLE }}</li>
{% endloop %}
</ul>

<p>Pagination</p>
<ul>
{% pageloop {rel: "pagination"} %}
    <li>{{ PAGE }} {% if CURRENT == PAGE %} current {% endif %} / last : {{ END }}</li>
{% endpageloop %}
</ul>

How to add your own extension

The tag thelia.parser.add_extension allows you to add your own twig extension.

    <tag name="thelia.parser.add_extension" />
</service>
