Views

A view is a full page or a page fragment—like a header, footer, or sidebar—and can be freely nested to form hierarchical layouts.

Creating Views

To understand, you can follow the example below, creating 3 files:

system/views/blog/header.php:


          <header>
            <h1>My Blog</h1>
          </header>

system/views/blog/header.php:


          <footer>
            <p>© <?=gmdate('Y')?> Meu Blog</p>
          </footer>

system/views/blog/index.php:


          <!DOCTYPE html>
          <html lang="pt-BR">
          <head>
            <meta charset="UTF-8" />
            <meta name="viewport" content="width=device-width, initial-scale=1.0" />
            <title>My Blog</title>
            <link rel="stylesheet" type="text/css" href="blog.css" />
          </head>
          <body>
            <?php
            View::render('blog.header');
            ?>

            <main>
              <h2><?=$title?></h2>
              <p><?=$contentes?></p>
            </main>

            <?php
            View::render('blog.footer');
            ?>
          </body>
          </html>

Then in the controller, callable, or closure, call the View::render() method like this:


          $app->action('GET', '/blog', function ($app, $params) {
            $entries = [
              'title' => 'My Blog',
              'contentes' => 'Neque porro quisquam est qui dolorem ipsum quia dolor sit amet, consectetur, adipisci velit.',
            ];

            View::render('blog.index', $entries);
          });

It's important to note that the view is only rendered after the route has been processed or if a serious exception or error occurs. Therefore, within a closure, callable, or controller method, you can use functions to control the header without worrying about errors, and you can define them in any order, for example:

$app->action('GET', '/foo', function ($app, $params) {
  View::render('bar.baz');

  header('Pragma: public');
  setcookie('mycookie', time());
});

With the View::share method you can share a value that will be accessible by the same variable in different Views, for example:

$app->action('GET', '/blog', function ($app, $params) {
  View::data('year', gmdate('Y'));
  View::data('hello', 'Hi!');

  View::render('foo');
  View::render('bar');
});

system/views/foo.php:


          <section>
            <h2>Foo view</h2>
            <p><?=$year?> - <?=$hello?></p>
          </section>

system/views/bar.php:


          <section>
            <h2>Bar view</h2>
            <p><?=$year?> - <?=$hello?></p>
          </section>

          <?php
          View::render('baz');
          ?>

system/views/baz.php:


          <section>
            <h2>Baz view</h2>
            <p><?=$year?> - <?=$hello?></p>
          </section>
