Code Style & Conventions

• PHP Standards: Follow PSR-12. Use 4 spaces for indentation.
• Naming: Classes PascalCase (e.g., CodePressCMS), methods camelCase (e.g., renderMenu), variables camelCase, config keys snake_case.
• Architecture:
  • Core CMS logic in cms/core/class/CodePressCMS.php
  • Bootstrap/requires in cms/core/index.php
  • Configuration loaded from config.json via cms/core/config.php
  • Public website entry point: public/index.php
  • Admin entry point + routing: public/admin.php
  • Admin authenticatie: admin/src/AdminAuth.php
• Content: Stored in content/. Supports .md (Markdown), .php (Dynamic), .html (Static).
• Templating: Mustache-style {{placeholder}} in templates/layout.mustache via SimpleTemplate.php.
• Navigation: Auto-generated from directory structure. Folders require an index file to be clickable in breadcrumbs.
• Security:
  • Always use htmlspecialchars() for outputting user/content data
  • Use realpath() + prefix-check for path traversal prevention
  • Admin forms require CSRF tokens via AdminAuth::verifyCsrf()
  • Passwords stored as bcrypt hashes in admin.json
• Git: main is the clean CMS core. development is de actieve development branch. e.noorlander bevat persoonlijke content. Niet mixen.

Admin Console

• File-based: Geen database. Gebruikers opgeslagen in admin/config/admin.json
• Routing: Via ?route= parameter in public/admin.php
• Routes: login, logout, dashboard, content, content-edit, content-new, content-delete, config, plugins, plugins-new, plugins-edit, plugins-config, plugins-toggle, plugins-delete, users
• Auth: Session-based. AdminAuth class handelt login, logout, CSRF, brute-force lockout af
• Templates: Pure PHP templates in admin/templates/pages/. Layout in layout.php

Important: Title vs File/Directory Name Logic

• CRITICAL: When user asks for "title" corrections, they usually mean FILE/DIRECTORY NAME WITHOUT LANGUAGE PREFIX AND EXTENSIONS, not the HTML title from content!
• Examples:
  • nl.test.md → display as "Test" (not content title)
  • nl.test/ directory → display as "Test" (not H1 content)
  • en.php-testen → display as "Php Testen" (not "ICT")
• Method: Use formatDisplayName() to process file/directory names correctly
• Priority: Directory names take precedence over file names when both exist
• Language prefixes: Dynamisch verwijderd op basis van beschikbare talen via getAvailableLanguages()

Bekende aandachtspunten

• LSP errors over "Undefined function" in PHP files zijn vals-positief (standaard PHP functies worden niet herkend door de LSP). Negeer deze.
• Zie TODO.md voor alle openstaande verbeteringen en nieuwe features.
• vendor/ map bevat Composer dependencies (CommonMark, Mustache). Niet handmatig wijzigen.
• admin/config/admin.json bevat wachtwoord-hashes. Niet committen met echte productie-wachtwoorden.
