How It Works

  1. Create or edit content
  2. Add translation (ES, FR, etc.)
  3. Plugin creates linked posts
  4. URLs are automatically generated
  5. Language switcher connects everything

Architecture

TranslatePlus now uses a modular kernel inspired by large-scale multilingual plugins:

  • Single bootstrap entrypoint (translateplus.php) with lifecycle hooks
  • Lightweight service container for shared plugin context
  • Module loader that registers and boots feature modules
  • Frontend module (rewrites, switcher, browser language redirect)
  • Translation module (auto-sync and translation orchestration)
  • Admin module (settings, editor tools, AJAX handlers)
  • Translation data model remains WordPress-native:
    • Each language = separate post
    • Posts linked by translation group metadata
    • Language stored in post meta

Development

Requirements

  • PHP 7.4+
  • WordPress 5.8+

Local Setup

git clone https://github.com/your-username/translateplus-wp.git
