Slim 3 Frameworkでtwigを使う

メモとして残しておく

app/settings.phpの編集

return [
    'settings' => [

        ・・・

        // View settings
        'view' => [
            'template_path' => '{テンプレートのパス}',
            'twig' => [
                'cache' => '{キャッシュのパス}',
                'debug' => true,
                'auto_reload' => true,
            ],
            'extension' => [
                \Twig_Extension_Debug::class
            ]
        ],

        ・・・
    ],
];

app/dependencies.phpの編集

<?php

$container = $app->getContainer();

// Twig
$container['view'] = function ($c) {
    $settings = $c->get('settings');
    $view = new \Slim\Views\Twig($settings['view']['template_path'], $settings['view']['twig']);
    // Add extensions
    $extensions = $settings['view']['extension'];
    foreach ($extensions as $extension_class) {
        $view->addExtension(new $extension_class);
    }
    return $view;
};

viewを表示してみる

public/index.php

<?php
require __DIR__ . '/../vendor/autoload.php';


$settings = require __DIR__ . '/../app/settings.php';
$app = new \Slim\App($settings);

require __DIR__ . '/../app/dependencies.php';

$app->get('/', function ($request, $response, $args) {
    $view = $this->get('view');
    $view->render($response, '{テンプレートの名前}', []);
    return $response;
});

$app->run();
