Running Hooks in the New System

Updating extension.json

To start using the new hook system, you need to update your extension's extension.json file. Define a handler class for your hooks by adding a new section called hookHandlers to the file:

{
    "name": "MyExtension",
    "version": "1.0",
    "author": "Your Name",
    "hookHandlers": {
        "default": "MyExtensionHooks"
    },
    "AutoloadClasses": {
        "MyExtensionHooks": "includes/MyExtensionHooks.php"
    }
}

Converting Static to Instance Methods

Next, you'll need to convert your existing static methods into instance methods in the MyExtensionHooks class:

// MyExtensionHooks.php

class MyExtensionHooks {
    // Convert static method to instance method
    public function onArticleFromTitle(Title &$title, &$page, &$redirect, &$article) {
        // Your hook logic here
    }

    // Add more instance methods for other hooks as needed
}

Hook Invocation

In your extension's code, use the Hooks class to run the hooks:

// Inside your extension code

Hooks::run('ArticleFromTitle', [ &$title, &$page, &$redirect, &$article ]);

Dependency Injection and Configuration

Define constructor parameters in your handler class to receive dependencies:

// MyExtensionHooks.php

class MyExtensionHooks {
    private $config;

    // Constructor with dependency injection
    public function __construct( Config $config ) {
        $this->config = $config;
    }

    // Instance method using injected dependency
    public function onArticleFromTitle(Title &$title, &$page, &$redirect, &$article) {
        // Access configuration settings
        $setting = $this->config->get('MyExtensionSetting');
        
        // Your hook logic here
    }
}
