PHP Dependency Injection for WordPress (based on Pimple)
This is nothing new but we added some magic:
- Compatible with projects using Pimple already
- Configuration via plain arrays, Yaml or other
- "Less WordPress more OOP"
and still searching for other magic to apply.
Add the package to your project
composer require rmp-up/wp-di
and set up the container provider
RmpUp\WpDi\WpDi::load( require 'services.php' );
$container = \RmpUp\WpDi\WpDi::pimple();
Friends of YAML can add composer require symfony/yaml
and use
RmpUp\WpDi\WpDi::load(
RmpUp\WpDi\Yaml::parseFile( 'services.yaml' )
);
A full documentation can be found in the documentation of the latest releases. The following is just a sneak peek into some of the possibilities. Try using the "preload.php" when you have PHP >= 7.4 or a composer workflow to get even more performance:
{
"autoload": {
"files": [ "vendor/rmp-up/wp-di/preload.php" ]
}
}
Define services as known from classical DI but also ...
- Primitive parameters as usual
- Default values for options
- Path to templates
- Inject all of them into services
- Allow factories to create services
# Primitive parameters as usual
parameters:
some: "primitives"
like: 42
# Default values for options
options:
_my_plugin_rating: 5/7
_this_is: cool
# Path to templates
templates:
admin-view: my-own-plugin/template-parts/fester.php
frontend-view: my-own-plugin/public/coogan.jpg
# looks up the file in theme, theme-compat and plugin directory
# Inject all of them into services
services:
SimpleOne:
arguments:
- "Hello there!"
- 1337
SomeThing:
arguments:
- "%like%" # the parameter
- "%_this_is%" # the option
- "%frontend-view%" # path to the template
- "@SimpleOne" # the other service
Services can also be used to ...
- Add actions / filters
- Add Meta-Boxes
- Register Post-Types
- Register Shortcodes
- Register Widgets
- Add WP-CLI commands
services:
StrrevEverything:
filter: the_content
# calling `::__invoke` for the "the_content"-filter
BackendAdminListThing:
meta_box:
title: Greatest box in the World!
screen: post
MyOwnPostType:
post_type: animals
# cast service to array and forward to register_post_type
BestShortcodeEver:
shortcode: shortcode_wont_die
widget: ~
# Shortcode and widget at once. Wow!
DoItCommand:
wp_cli:
do-it: __invoke
doit: __invoke
seriously do-it do-it do-it: seriously
# cli commands mapped to methods
Within YAML you can:
- Access PHP-Constants
- Concatenate text
- Translate text
Mostly lazy to get the best performance.
services:
# Access PHP-Constants
InjectingConstants:
arguments:
- !php/const ABSPATH
# Concatenate text
ThisIsSomeTemplate:
arguments:
- !join [ !php/const WP_CONTENT_DIR, "/plugins/grey-matter/walter.jpg" ]
# Translations within YAML
ThisThingNeedsTranslations:
arguments:
- !__ [ Who is Adam?, dark ]
- !esc_attr__ [ white ]
# ... many more translation functions available ...
All of this is only possible when using \RmpUp\WpDi\Yaml::parseFile(...)
or ::parse(...)
.
We used this in some projects and still maintain/enhance it, so please open an issue if there is anything we can help with.
