Multi-Language System

Database-driven translations with AI-powered auto-translate

Overview

Complete internationalization system. All strings use T::t() helper for translation lookup. Supports manual translations, Google Translate, OpenAI, Anthropic Claude, and DeepL for automatic translation.

Design Considerations

UX patterns and visual design notes for this feature:

•RTL languages need layout consideration
•German text is ~30% longer than English
•Flag emojis are cute but not accessible
•Language switcher placement affects discoverability

Key Benefits

What makes this feature stand out:

✓AI-powered auto-translation
✓5 translation providers supported
✓Database-cached for performance
✓URL-based language switching (/en/, /sl/)

Technical Note

T::t() wraps Yii::t() with database fallback and auto-translate. Uses codemix/yii2-localeurls for URL patterns. Translations stored in translation table.
