Rabbit Framework is a modern framework designed to be a solid foundation for your WordPress plugins. the project is based on Backyard
- Dependency injection container & service providers.
- template that helps you load the view easily.
- OOP Nonces wrapper & Factory methods.
- Caching helpers.
- HTTP Redirects with admin notices flashing.
- Macroable classes.
- LoggerWP
- Illuminate Database (Eloquent)
- PHP 7.4 or higher.
- Composer
composer require veronalabs/rabbitWhen creating a WordPress plugin, you are required to add header fields to your plugin's entry file. The Rabbit framework requires 1 additional field: Plugin Prefix.
The Plugin Prefix field is used by the framework to automatically define constants about the plugin.
/**
* Plugin Name: Example plugin
* Plugin URI: https://example.com
* Plugin Prefix: EP
* Description: Description
* Author: Alessandro Tesoro
* Author URI: https://example.com
* Text Domain: example-plugin
* Domain Path: /languages
* Version: 0.1.0
*/Copy and paste the code below right after the header fields to load all the dependencies of your plugin, including the Rabbit framework.
if ( file_exists( dirname( __FILE__ ) . '/vendor/autoload.php' ) ) {
require dirname( __FILE__ ) . '/vendor/autoload.php';
}Every Rabbit powered plugin must create an instance of a Rabbit Application. The application is responsible for the loading of the plugin.
Create a new application instance by using the get() method.
$myPlugin = Application::get();The framework handles a plugin through the Plugin class. The Plugin class is an extension of the PHP League dependency injection container. The container is responsible for the loading of configuration files, the registration & booting process of service providers and more.
After the instantiation of a Rabbit Application, you need to load your plugin into the application via the loadPlugin() method.
The loadPlugin() method takes 3 arguments, the third is optional.
-
The path to the plugin.
-
The path to plugin's entry file.
-
The name of the folder that holds the configuration files.
$myPlugin = $myPlugin->loadPlugin( DIR, FILE, 'config' );
The loadPlugin() method returns the Plugin container. You will then use the container to add functionalities to your plugin.
Configuration files provide an easy way to set options required by parts of application to work. Values can then be easily accessed by the plugin. A configuration file returns an associative array.
$myPlugin->config( 'key' );Use the config() method to access values. Keys use dot notation starting with the name of the configuration file. Take a look at the example below:
File: config/plugin.php
<?php
$config = [
'my_key' => 'my_value',
];In order to access the my_key value, you need to call the config() method this way:
$value = $myPlugin->config( 'my_key' );Configuration files are used by some features provided by Rabbit.
Service providers in Rabbit are used to add functionalities to your plugin. Providers can be loaded by using the addServiceProvider() method of the container class.
$myPlugin->addServiceProvider( RedirectServiceProvider::class );Activation and deactivation hooks provide ways to execute actions when the plugin is activated or deactivated. If you're familiar with these hooks, you may remember they are called with the register_activation_hook and register_deactivation_hook functions.
In Rabbit you can register the activation and deactivation process by using the onActivation and onDeactivation methods of the Plugin class. Both methods use a Closure as argument.
$myPlugin->onActivation(
function() use ( $myPlugin ) {
// Do something on activation here like update_option()
}
);
$myPlugin->onDeactivation(
function() use ( $myPlugin ) {
// Do something on deactivation here
}
);Use the boot() method of the Plugin class to boot your plugin. The boot() method uses a Closure that allows you to add more functionalities to your plugin.
When booting, the plugin boots the registered service providers on the plugins_loaded hook.
To boot your plugin use the following snippet:
$myPlugin->boot(
function( $plugin ) {
// Do something when the plugins_loaded hook is fired.
}
);If your plugin requires localization, you can use the loadPluginTextDomain method inside the boot method. The framework will use the information in your header fields to set the correct textdomain and languages folder path.
$myPlugin->boot(
function( $plugin ) {
$plugin->loadPluginTextDomain();
}
);The Rabbit framework comes with an easy way to include() files in your WordPress plugin. Use the includes() method of the Plugin class to include files from a specific folder. Files are loaded alphabetically.
$myPlugin->boot(
function( $plugin ) {
$plugin->includes( 'includes' );
}
);The example above will automatically include *.php files from the includes subfolder of your plugin.
