Twig for WordPress
Twig for WordPress allow you to use the famous Twig template engine https://twig.symfony.com/
but extend it to be able to use the functions provided by WordPress such as esc_html
, esc_html__
, wp_kses
etc...
This package register the escape function as filters and functions because translator functions need to be pass a textdomain.
Modules
The package provide filters, functions and other stuffs into twig by define modules
.
Modules are class instances that implements an interface TwigWp\Module\Injectable
used by
the Provider TwigWp\Module\Provider
that allow us to retrieve all modules to be set into twig
instance.
There is a filter twigwp.modules
within the Provider::modules
method that allow
third party softwares to hook into the modules list so, they'll be able to add other filters, functions, tags
or whatever they want to use to extend the twig instance
(read about how to extend twig here https://twig.symfony.com/doc/2.x/advanced.html).
Escapers
Twig for WordPress define as filters and functions the followings:
- esc_js
- esc_sql
- esc_textarea
- esc_url
- esc_url_raw
- esc_attr
- esc_html
Kses
The kses are defined only as functions.
- wp_kses
- wp_kses_post
- wp_kses_allowed_html
Sanitizers
The sanitizers are defined only as functions.
- sanitize_html_class
- sanitize_text_field
- sanitize_title
- sanitize_key
L10n
Localization functions, including the escaped ones.
Localizations functions that start with esc_
(escape) are also registered as filters.
- __
- _e
- _n
- _x
- _ex
- _nx
- esc_attr__
- esc_attr_e
- esc_attr_x
- esc_html__
- esc_html_e
- esc_html_x
Template Functions
This module include all of the functions that echo html markup even if them are not WordPress template functions.
This because most of the WordPress functions usually get some configuration by array and output html markup. Having to put in a object property the entire markup isn't usefull since you want to have your markup into your views, these functions will help you to pass the configuration and call the output function directly, avoiding to permit to parse html markup that may result in a unescaped html.
- wp_nav_menu
- get_adjacent_post_link
Provider
The modules are retrieved by a Provider.
Within the provider the modules can be filtered twigwp.modules
.
So if you want to add a new module you can hook into this filter and return a new instance of TwigWp\Module\Injectable
.
A Module is used to extend the twig instance, the method injectInto
get a \Twig\Environment
instance to use for example
to add a new function, a new filter or a new tag etc...
For example:
class MyModule implements TwigWp\Module\Injectable { public function injectInto(\Twig\Environment $twig): \Twig\Environment { // Do your stuffs here. return $twig; } } $provider = new Provider(new \Twig\Environmnet()); add_filter('twigwp.modules', function($modules) { $modules['module_name'] = new MyModule(); return $modules; }); $modules = $provider->modules();
This is just an example because you'll never need to create an instance of the Module Provider
.
Everything is handled by the Factory
class.
You just need to add your filter and everything is ok.
Factory
The package provide a Factory
class that help you on creating a new instance of the \Twig\Environment
class.
If you want to create a new Twig instance you can simply create a factory instance by passing
a \Twig\Loader\LoaderInterface
object and the twig options if you want to customize the environment.
Then call the create
method and you've done.
$twigFactory = new \TwigWp\Factory( new \Twig\Loader\FilesystemLoader(), [ 'debug' => false, 'charset' => 'UTF-8', 'base_template_class' => 'Twig_Template', 'strict_variables' => false, 'autoescape' => 'html', 'cache' => false, 'auto_reload' => null, 'optimizations' => -1, ] ); $twig = $twigFactory->create();
Pretty easy, right?
