Architecture

Generated: 2026-04-26

Overview

cmsPRO uses a 3-layer architecture with clean admin/frontend separation:

Request
  ↓
Controls (admin\controls\ or front\controls\)   ← request handling
  ↓
Factories (admin\factory\ or front\factory\)    ← DEPRECATED wrappers → will be removed
  ↓
Domain Repositories (Domain\*\*Repository)      ← data access (new pattern)
  ↓
Medoo ORM → MySQL

Views are rendered through admin\view\* / front\view\* → Shared\Tpl\Tpl → Savant3 templates.

Key Patterns

Repository Pattern (Domain layer)

class ArticlesRepository {
    public function __construct($db) { $this->db = $db; }
    public function find(int $id): ?array { ... }
    public function save(...): int { ... }
}

Factory Wrapper (deprecated bridge)

/** @deprecated Używaj Domain\Articles\ArticlesRepository przez DI */
class Articles {
    private static function repo(): ArticlesRepository {
        global $mdb;
        return new ArticlesRepository($mdb);
    }
    public static function article_delete($id): bool {
        return self::repo()->deleteArticle($id);
    }
}

Controls (request handler)

class Articles {
    public static function article_delete() {
        global $user;
        if (!admin\factory\Users::check_privileges('articles', $user['id']))
            return \S::alert('Brak uprawnień');
        // delegate to factory → repository
    }
}

Global Helper Facade

// class.S.php — calls Shared\Helpers\Helpers via __callStatic
\S::get('param')          // → Helpers::get()
\S::delete_cache()        // → Helpers::delete_cache()

Admin Routing

GET /admin/?a=articles&action=view_list → admin\controls\Articles::view_list()

Routing in admin/index.php: reads $_GET['a'] → dynamically loads control class → calls action method.

Frontend Routing

index.php → front\controls\Site::route() — checks \S::get('search'), \S::get('tag'), \S::get('article'), then falls through to page rendering by page_type.

Caching Strategy

Cache Type	Location	Engine
Page cache	cache/	Full HTML output
Object cache	temp/md5[0]/md5[1]/	gzdeflate + serialize, TTL
WebP images	cache/	Filesystem
Language strings	$_SESSION	PHP session

Plugin System

3 hook points in frontend lifecycle (files in plugins/ directory, included if they exist):

1. special-actions.php — after language init, before routing
2. special-actions-middle.php — before cache check
3. special-actions-end.php — before final output
