Legal Document Viewer

The PLANOVI Document Center (documentation.php) provides users, cooperative members, and regulators with instant in-browser access to legal terms, privacy policies, and GDPR agreements.

1. Storage Organization (documents/)

Legal documents are organized strictly by ISO language code within the documents/ root directory:

planovi-webpage/
└── documents/
    ├── pl/
    │   ├── polityka_prywatnosci.pdf    # Polish Privacy Policy (GDPR / RODO)
    │   └── regulamin.pdf               # Polish Terms of Service
    └── en/
        ├── privacy_policy.pdf          # English Privacy Policy
        └── terms_and_conditions.pdf    # English Terms & Conditions

---

2. Server-Side Document Discovery

On page load, documentation.php scans the filesystem dynamically to discover available documents without hardcoded file lists:

$baseDir = __DIR__ . '/documents';
$langs = ['pl', 'en'];
$filesData = [];

foreach ($langs as $lang) {
    $dirPath = $baseDir . '/' . $lang;
    if (is_dir($dirPath)) {
        $files = array_diff(scandir($dirPath), ['.', '..', '.DS_Store']);
        $filesData[$lang] = array_values($files);
    } else {
        $filesData[$lang] = [];
    }
}

$jsonFiles = json_encode($filesData);

The resulting $jsonFiles payload is passed to the client script to populate the document selector dynamically.

3. Client-Side Iframe Rendering

When a visitor switches language or selects a document from the dropdown:

function loadFile() {
    const select = document.getElementById('fileSelect');
    const viewer = document.getElementById('pdfViewer');
    const placeholder = document.getElementById('docsPlaceholder');

    if (select.value) {
        // Appending #toolbar=0 prevents browser PDF chrome from cluttering the glass card
        const filePath = `documents/${docsLang}/${select.value}#toolbar=0`;
        viewer.src = filePath;
        viewer.style.display = 'block';
        placeholder.style.display = 'none';
    }
}

Key UI Features:

• Clean Embedding: The #toolbar=0 hash suppresses extraneous browser controls for a sleek embedded experience.
• Dynamic File Labeling: File names like polityka_prywatnosci.pdf are automatically formatted into readable titles: POLITYKA PRYWATNOSCI.
• Seamless Language Switching: Toggling between PL and EN automatically re-filters the dropdown to the active locale’s files.
