Twig Integration for Expressive

Repository abandoned 2019-12-31

This repository has moved to mezzio/mezzio-twigrenderer.

Provides Twig integration for Expressive.

Installation

Install this library using composer:

$ composer require zendframework/zend-expressive-twigrenderer

We recommend using a dependency injection container, and typehint against container-interop. We can recommend the following implementations:

• zend-servicemanager: composer require zendframework/zend-servicemanager
• pimple-interop: composer require mouf/pimple-interop
• Aura.Di: composer require aura/di

Twig Extension

The included Twig extension adds support for url generation. The extension is automatically activated if the UrlHelper and ServerUrlHelper are registered with the container.

• path: Render the relative path for a given route and parameters. If there is no route, it returns the current path.

  {{ path('article_show', {'id': '3'}) }}
  Generates: /article/3

  path supports optional query parameters and a fragment identifier.

  {{ path('article_show', {'id': '3'}, {'foo': 'bar'}, 'fragment') }}
  Generates: /article/3?foo=bar#fragment

  By default the current route result is used where applicable. To disable this the reuse_result_params option can be set.

  {{ path('article_show', {}, {}, null, {'reuse_result_params': false}) }}

• url: Render the absolute url for a given route and parameters. If there is no route, it returns the current url.

  {{ url('article_show', {'slug': 'article.slug'}) }}
  Generates: http://example.com/article/article.slug

  url also supports query parameters and a fragment identifier.

  {{ url('article_show', {'id': '3'}, {'foo': 'bar'}, 'fragment') }}
  Generates: http://example.com/article/3?foo=bar#fragment

  By default the current route result is used where applicable. To disable this the reuse_result_params option can be set.

  {{ url('article_show', {}, {}, null, {'reuse_result_params': false}) }}

• absolute_url: Render the absolute url from a given path. If the path is empty, it returns the current url.

  {{ absolute_url('path/to/something') }}
  Generates: http://example.com/path/to/something

• asset Render an (optionally versioned) asset url.

  {{ asset('path/to/asset/name.ext', version=3) }}
  Generates: path/to/asset/name.ext?v=3

  To get the absolute url for an asset:

  {{ absolute_url(asset('path/to/asset/name.ext', version=3)) }}
  Generates: http://example.com/path/to/asset/name.ext?v=3

Configuration

If you use the zend-component-installer the factories are configured automatically for you when requiring this package with composer. Without the component installer, you need to include the ConfigProvider in your config/config.php. Optional configuration can be stored in config/autoload/templates.global.php.

'templates' => [
    'extension' => 'file extension used by templates; defaults to html.twig',
    'paths' => [
        // namespace / path pairs
        //
        // Numeric namespaces imply the default/main namespace. Paths may be
        // strings or arrays of string paths to associate with the namespace.
    ],
],
'twig' => [
    'cache_dir' => 'path to cached templates',
    'assets_url' => 'base URL for assets',
    'assets_version' => 'base version for assets',
    'extensions' => [
        // extension service names or instances
    ],
    'runtime_loaders' => [
        // runtime loaders names or instances   
    ],
    'globals' => [
        // Global variables passed to twig templates
        'ga_tracking' => 'UA-XXXXX-X'
    ],
    'timezone' => 'default timezone identifier, e.g.: America/New_York',
    'optimizations' => -1, // -1: Enable all (default), 0: disable optimizations
    'autoescape' => 'html', // Auto-escaping strategy [html|js|css|url|false]
    'auto_reload' => true, // Recompile the template whenever the source code changes
    'debug' => true, // When set to true, the generated templates have a toString() method
    'strict_variables' => true, // When set to true, twig throws an exception on invalid variables
],
