Laminas View Laravel Package

Getting Started

Start by installing via Composer: composer require laminas/laminas-view. In a Laminas MVC application, it's already wired in via the full skeleton, but for custom setups (e.g., Expressive/Mezzio or standalone), bind the renderer and view manager manually. Begin with the simplest use case: render a PHP template with a ViewModel:

// In a controller action
use Laminas\View\Model\ViewModel;

public function indexAction()
{
    $viewModel = new ViewModel(['title' => 'Hello World']);
    $viewModel->setTemplate('layout/main'); // optional
    return $viewModel;
}

Then create view/layout/main.phtml and view/application/index/index.phtml. The default renderer is Laminas\View\Renderer\PhpRenderer, and templates are resolved automatically using configured view paths. Check config/autoload/global.php for view_manager.template_path_stack.

Implementation Patterns

• Hierarchical Layouts: Use ViewModel::setParent() or ViewModel::addChild() to nest view models for reusable page structures (e.g., main layout → sidebar → content block).
• Strategy-Based Rendering: Switch renderers via ViewModel::setTerminal(true) + laminas/laminas-json-parser for JSON APIs, or use JsonModel (if laminas/laminas-mvc is present).
• Helper Composition: Inject view helpers (e.g., baseUrl(), escapeHtml(), partial()) in templates. Register custom helpers via plugin manager in configuration:

  'view_helpers' => [
      'invokables' => [
          'myHelper' => My\Helper::class,
      ],
  ];
  

• Escaping Contexts: Use escapeHtml(), escapeJs(), escapeCss(), escapeUrl() explicitly—don’t assume automatic escaping in templates.
• Templating Engines: Integrate Twig orSmarty via laminas/laminas-view-strategy-twig or custom renderer, but prefer PhpRenderer for tight Laminas integration.

Gotchas and Tips

• Cache Busting: Template changes won’t reflect if config/cache.php has view_manager.cache_dir enabled—clear cache manually or disable in dev.
• Helper Injection Pitfalls: View helpers are not injected into controllers—use viewHelperManager or getServiceManager()->get('ViewHelperManager') only inside templates.
• Renderer Selection: The renderer isn’t auto-switched per route/controller; explicitly set ViewModel::$template or use JsonModel/TerminalViewModel to avoid HTML rendering when JSON is intended.
• Security: While escaping helpers exist, never rely on them alone—always validate/sanitize input before passing to view models.
• Testing Tip: Render templates in isolation with Renderer\PhpRenderer and mocked view model—no HTTP stack needed:

  $renderer = new PhpRenderer();
  $renderer->setResolver(new Resolver\TemplateMapResolver(['test' => __DIR__ . '/test.phtml']));
  echo $renderer->render(new ViewModel(['var' => 'test']), 'test');
