CMS Studio

Scaffold with DotApper

Never hand-create the module skeleton. Generate it, then fill in routes and classes.

php dotapper.php --create-module=Studio
php dotapper.php --module=Studio --create-controller=Site
php dotapper.php --module=Studio --create-controller=Admin
php dotapper.php --module=Studio --create-middleware=DeskGate

--module= must appear before --create-controller / --create-middleware. That creates app/modules/Studio/ with Controllers/, Middleware/, Libraries/, views/, assets/, and module.init.php. DotApper also drops placeholder files you can ignore or replace: Api/Api.php, Controllers/Controller.php, views/clean.view.php, views/layouts/example.layout.php, module.listeners.php.

What you then write by hand (this walkthrough):

Routes: the complete module.init.php

Static controllers: 'Studio:Site@home!'. Trailing ! is required. Pair each path with and without a trailing slash. Dynamic article slugs are not STATIC_ROUTE. Register exact admin paths before /admin/articles/{slug:s} so /admin/articles is not swallowed. Write POSTs attach ->before('#Studio:DeskGate@write!'). There is no Laravel Route::group().

Read slugs with $request->matchData()['slug']. Missing article → new Response(404, 'Article not found').

Renderer helper: the complete View.php

Call Renderer::new()->module('Studio')->setView($name) before setViewVar. A view that fails to render returns "" — log it and return HTTP 500. page() is a full HTML document (chrome). fragment() is an inner view swapped into {{ var: $bodyHtml }}. There is no Blade, no Twig, no PHP include inside a view.

Schéma: celý súbor Installation.php

CMS nie je „jedna tabuľka článkov“. Magazín, desk, menu, médiá aj nastavenia potrebujú vlastnú tabuľku, ktorú vlastní modul. Každá tabuľka je studio_*. Nikdy neprefixované názvy, nikdy dotapp_* pre dáta štúdia. Funkčné DB::migrate() neexistuje. Verziované SQL píšete do Installation.php, ktoré rozširuje Installer.

Verejná ukážka tento inštalátor nespúšťa. Živé stránky čítajú PHP polia z Libraries/Press.php, aby návštevník nemohol urobiť INSERT. Vo vlastnom projekte tento súbor skopírujete a z initialize() zavoláte Installation::module('Studio')->install(), keď je databáza nastavená.

Na čo ktorá tabuľka slúži — toto zloženie starý snippet schoval:

Čítajte triedu zhora nadol. installer() vracia pole callbackov podľa verzie. alreadyDone('1.0.0') podľa potreby vytvorí studio_installations a skončí, ak je verzia už označená. Potom v slučke beží každý CREATE TABLE. Až keď uspejú všetky, volá sa markDone('1.0.0') — nie v success callbacku prvej tabuľky. To by označilo modul ako nainštalovaný po jednej tabuľke. uninstaller() maže v opačnom poradí (položky pred menu, články pred témami).

Na ostrom webe to zapojte z module.init.php (nie na tejto verejnej ukážke):

$dbs = Config::get('databases');
if (is_array($dbs) && $dbs !== []) {
    try {
        Installation::module('Studio')->install();
    } catch (\Throwable $e) {
        Logger::use()->error('Studio install skipped', ['msg' => $e->getMessage()]);
    }
}

Zoznamy, ktoré môžu rásť, musia použiť ->paginate($perPage, $page) plus AJAX pager od prvého dňa. Produkčný zoznam článkov (ukážka namiesto toho používa Press::paginateArticles() v pamäti):

$result = DB::module('RAW')->q(function ($qb) use ($q, $useSearch) {
    $qb->select(['id', 'title', 'status', 'published_at'])
        ->from('studio_articles')
        ->orderBy('id', 'DESC');
    if ($useSearch) {
        $esc = str_replace(['\\', '%', '_'], ['\\\\', '\%', '\_'], $q);
        $qb->where('title', 'LIKE', '%' . $esc . '%');
    }
})->paginate(10, $page);

Produkčné menu pre verejné <nav> — odtiaľto prídu odkazy Home / Services / Insights / Company / Contact, keď opustíte Press.php:

$menu = DB::module('RAW')->q(function ($qb) {
    $qb->select(['i.id', 'i.label', 'i.href', 'i.pos'])
        ->from('studio_menu_items', 'i')
        ->join('studio_menus m', 'm.id', '=', 'i.menu_id')
        ->where('m.code', '=', 'primary')
        ->orderBy('i.pos', 'ASC');
})->all();

Public site: where templates and the menu come from

The studio site is two layers. A document view owns <html>, the EXAMPLE ribbon, the sticky header, dropdowns, the footer, CSS, and scripts. An inner view is only the <main> body (home, one insight, contact form). PHP renders the inner view first, then injects that HTML string as $bodyHtml into the document. That is why you do not include templates and you do not put a second <html> in site-home.view.php.

Every public view file

Template rules: close with {{ /if }} and {{ /foreach }}, never endif. Print with {{ var: $title }} only — there is no {{ $title }}. Layout partials use {{ layout:name }}. PHP include in a view is forbidden.

How a page is assembled

Site::home() loads sample rows from Press::articles(), then calls private site('site-home', ...). That helper renders the fragment, then the document. Copy this method — it is the whole composition:

File: app/modules/Studio/Controllers/Site.php — method site()

private static function site(string $inner, string $pageLabel, string $path, array $vars)
{
    $p = View::prefix();
    $innerVars = $vars;
    $innerVars['prefix'] = $p;
    $body = View::fragment($inner, $innerVars);
    $nav = (string) ($vars['nav'] ?? '');

        'nav' => $nav,

        'menu' => Press::nav($nav),
    ]));
}

Where the menu comes from

The desk table still uses a flat Press::menu() (Home / Services / Insights / Company / Contact). The public header uses Press::nav($active), which adds dropdown children for Services, Insights, and Company. site.view.php loops $menu into <nav> and nested $item['kids'] into the panels. On a real CMS you replace both helpers with a query on studio_menu_items (see Schema). The view file does not change.

File: app/modules/Studio/Libraries/Press.php — method menu()

public static function menu(): array
{
    $p = View::prefix();
    return [
        ['id' => 1, 'label' => 'Home', 'href' => $p . '/', 'pos' => 1],
        ['id' => 2, 'label' => 'Services', 'href' => $p . '/topics', 'pos' => 2],
        ['id' => 3, 'label' => 'Insights', 'href' => $p . '/insights', 'pos' => 3],
        ['id' => 4, 'label' => 'Company', 'href' => $p . '/about', 'pos' => 4],
        ['id' => 5, 'label' => 'Contact', 'href' => $p . '/contact', 'pos' => 5],
    ];
}

Home fragment

No <html> here. Variables come from Site::home(): $settings, $featured, $topics, $articles, $team, $clients, $prefix. The live home is a full studio landing (hero photograph, services, insights, partners). Copy app/modules/Studio/views/site-home.view.php.

File: app/modules/Studio/views/site-home.view.php — opening of the live file

<section class="lp-hero">
  <div>
    <p class="lp-kicker">Bratislava software studio</p>
    <h1>{{ var: $settings['tagline'] }}</h1>
    <p class="lp-lead">Lumen Press designs platforms, cloud estates, and product surfaces for operators who still want the keys.</p>

      <a class="lp-btn lp-btn-ghost" href="{{ var: $prefix }}/contact">Start a conversation</a>
    </div>
  </div>
</section>

Contact form

Always $request->crcCheck() first. Always $request->data(true)['data'] for the payload. Always DotApp::DotApp()->ajaxReply($body, $code). Put {{ formName(contactForm) }} between the <fo-rm> tags.

$answer = $request->form(['POST'], 'contactForm', function ($request) {
    $data = $request->data(true)['data'] ?? [];
    $email = trim((string) ($data['email'] ?? ''));
    if (!Validator::isEmail($email)) {
        return ['code' => 200, 'body' => ['status' => 0, 'message' => 'Enter a valid email.']];
    }
    return ['code' => 200, 'body' => [
        'status' => 1,
        'message' => 'Thanks. We received your note.',
    ]];
}, function () {
    return ['code' => 403, 'body' => ['status' => 0, 'message' => 'Invalid signature']];
}, $request->getPath());

Administration: desk templates and the write lock

The desk is the same module, a second document. Sidebar + lock banner live in admin.view.php. On a phone the sidebar is an off-canvas drawer (#stDeskMenuBtn). Each screen is a fragment rendered into {{ var: $bodyHtml }} the same way as the public site. Login is a separate document: admin-login.view.php with a fo-rm named loginForm.

Every desk view file

Locked login (this demo)

The handler still uses crcCheck + $request->form(..., 'loginForm', ...). It never calls Auth::login(). Any email/password pair returns status 0. That is intentional.

return ['code' => 200, 'body' => [
    'status' => 0,
    'locked' => 1,
    'message' => 'Unable to sign in.',
]];

Production login

Copy the Users module pattern: Auth::login(['email' => $email, 'password' => $password, 'stage' => 0], $remember), then redirect to the desk. Protect GET desk routes. Do not ship that gate on this public docs site.

Router::get($pair($p . '/admin/desk'), 'Studio:Admin@desk!', Router::STATIC_ROUTE)
    ->before('#Studio:DeskGate@check!');

public static function check($request)
{
    if (!Auth::isLogged()) {
        return Response::redirect($prefix . '/admin', 302);
    }
    if (!Auth::can(['Studio.desk'])) {
        return new Response(403, 'Forbidden');
    }
}

Write lock: the complete DeskGate.php

Every mutating admin POST is registered with ->before('#Studio:DeskGate@write!'). Returning a Response from a before-hook stops the controller. The article editor is still a real fo-rm so loaders work — Save posts, this gate rejects, the row does not change. Delete uses a graphical confirm (never alert / confirm). Menu up/down is buttons + load(), not a fo-rm per arrow.

            'message' => 'This public demo never writes content. Sign-in is disabled, so nobody can insert or change rows here.',

Encrypted ids

Different extra keys per field. Encryption is not authorization — on a real desk still call Auth::can(). These are field names, not secrets.

$enc = Crypto::encrypt((string) $row['id'], 'Studio.article.id');
$id = Crypto::decrypt((string) ($data['id'] ?? ''), 'Studio.article.id');
if ($id === false) {
    return DotApp::DotApp()->ajaxReply(['status' => 0, 'message' => 'Invalid item.'], 200);
}

Keys used in this module: Studio.article.id, Studio.page.id, Studio.menu.id, Studio.media.id, Studio.topic.slug.

dotapp.js: formuláre, zoznamy, confirm

Najprv načítajte /assets/dotapp/dotapp.js. Logika stránky počúva udalosť dotapp. $dotapp nie je jQuery. $dotapp().live() volá handler(element, event) — prvý argument je nájdený uzol.

(function () {
  var runMe = function ($dotapp) {
    $dotapp().form("#loginForm").before(function (data, form) {
      if ($dotapp(form).attr("blocked") == 1) return $dotapp().halt();
      $dotapp(form).attr("blocked", "1");
      $dotapp("#loginBtn").attr("loading", "true").attr("loader", "dots");
    }).after(function (data, response, form) {
      var reply = $dotapp().parseReply(response);
      if (reply && reply.message) $dotapp("#error-message").attr("hide", "false").html(reply.message);
      $dotapp(form).attr("blocked", "0");
      $dotapp("#loginBtn").removeAttr("loading").removeAttr("loader");
    });
  };
  if (window.$dotapp) runMe(window.$dotapp);
  else window.addEventListener("dotapp", function () { runMe(window.$dotapp); }, { once: true });
})();

Zoznamy článkov a médií: debounce input, hľadanie od troch znakov, overlay .lp_busy počas letu, záplata #listInner cez reply.html. Pager tlačidlá sú type="button" s data-page. Lepkavá hlavička tabuľky + <mark> na zhody sú povinné pri lookup zoznamoch.

$dotapp().live("click", ".js-st-page", function (el, ev) {
  var btn = (el && el.nodeType === 1) ? el : ev.currentTarget;
  var page = parseInt(btn.getAttribute("data-page"), 10) || 1;
  $dotapp().load(listUrl, "POST", { page: page, q: currentQuery }, function (raw) {
    var reply = $dotapp().parseReply(raw);
    if (reply && reply.html) $dotapp("#listInner").html(reply.html);
  });
});

Súbory: $dotapp().uploadFile(file, url, progress) — nikdy FormData na load() ani fo-rm (CRC neobalí binár). Verejná ukážka upload nenasadzuje, aby návštevník nemohol položiť súbory na server.

Session pre košík/drafty/filtre: DSM::use('Studio'), nikdy $_SESSION.

Produkčný checklist

• Scaffold cez DotApper. Tabuľky len studio_*.
• Verejný web: slugy, témy, fo-rm kontakt, CSS modulu, Renderer + fragmenty.
• Desk: Auth::isLogged() + Auth::can('Studio.desk') na každom GET okrem login stránky.
• Zápisy: crcCheck, unikátne extra kľúče, znova Auth::can, potom INSERT/UPDATE.
• Rastúce zoznamy: paginate() + AJAX pager + hľadanie od 3 znakov + overlay + prázdny stav + sticky header + highlight.
• Akcie v riadku: tlačidlá + load(). Jeden editor fo-rm na obrazovku. Delete cez modal.
• Médiá: uploadFile, stránkovaná knižnica, šifrované media id.
• Nevymýšľajte Blade/Eloquent/jQuery API. Ak to nie je v AIRULES, otvorte app/parts len na čítanie.
