Overview

This plugin has been completely redesigned using modern development principles and architectural patterns.

Key Improvements

1. Dependency Injection Container

• Centralized dependency management
• Automatic service instance creation
• Easy testing and extensibility

2. Service Layer Pattern

• Separation of business logic into separate services
• Each service is responsible for specific functionality
• Easy code reuse

3. MVC Architecture

• Controllers for request handling
• Views for data display
• Models (services) for business logic

4. Configuration Management

• Centralized settings management
• Typed methods for configuration work
• Automatic settings validation

5. Hook Management

• Structured WordPress hook management
• Automatic registration of all hooks
• Easy addition of new hooks

Installation and Usage

Requirements

• PHP 7.4+
• WordPress 5.0+

Installation

1. Copy files to wp-content/mu-plugins/ directory
2. Activate plugin through admin panel
3. Configure options in "j|D Support" section

Development

Adding a new service

// 1. Create service in src/Services/
class NewService
{
    public function __construct(Container $container)
    {
        $this->config = $container->get('config');
    }
    
    public function doSomething()
    {
        // Your logic
    }
}

// 2. Register in Container.php
$this->register('new', NewService::class);

// 3. Use in HookManager.php
$this->addAction('hook_name', [$this->container->get('new'), 'doSomething']);

Adding a new controller

// 1. Create controller in src/Admin/Controllers/
class NewController
{
    public function registerHooks()
    {
        add_action('admin_menu', [$this, 'addMenuPage']);
    }
}

// 2. Add to AdminManager.php
$this->newController = new NewController($this->container);
$this->newController->registerHooks();

Testing

Running tests

composer test

Code checking

composer phpcs    # Code style check
composer phpstan  # Static analysis
composer fix      # Auto-fix style

Migration from old version

Main changes

1. File structure: Completely redesigned
2. Namespace: PSR-4 autoloading used
3. Dependency Injection: Dependency container implemented
4. Service Layer: Business logic separated into services
5. Configuration: Centralized settings management

Compatibility

• All existing settings are preserved
• Hook API remains compatible
• Functionality unchanged

Advantages of new architecture

1. Maintainability

• Clear separation of responsibilities
• Easy understanding of code structure
• Simple addition of new features

2. Testability

• Each component can be tested separately
• Dependency Injection simplifies mocking
• Automated tests

3. Extensibility

• Easy addition of new services
• Modular architecture
• Component reuse

4. Performance

• Loading only necessary classes
• Optimized dependency container
• Configuration caching
