How do I show data from my database in SLIM/TWIG templates?

Hello everyone,

As I watched the videos of Slim/Twig I decided to go this route for my website. It works fine now but one problem. I have absolutely no idea on how to integrate mysql database.

Here is my index.php file where is my slim and my connection to the database.

'''php

use \Psr\Http\Message\ServerRequestInterface as Request;

use \Psr\Http\Message\ResponseInterface as Response;

require 'vendor/autoload.php';

$app = new \Slim\App();

$container = $app->getContainer();

$container['view'] = function ($container) {

$view = new \Slim\Views\Twig('templates', [

    'cache' => false
]);
$view->addExtension(new \Slim\Views\TwigExtension(
    $container['router'],
    $container['request']->getUri()
));

return $view;

};

// Render Twig template in route $app->get('/', function ($request, $response, $args) { return $this->view->render($response, 'home.twig' ); });

$app->get('/about', function ($request, $response, $args) { return $this->view->render($response, 'about.twig' ); });

$app->get('/contact', function ($request, $response, $args) { return $this->view->render($response, 'contact.twig' ); });

$app->get('/upload', function ($request, $response, $args) { return $this->view->render($response, 'upload.twig' ); });

$dsn = 'mysql:host=localhost;dbname=database;charset=utf8'; $usr = 'root'; $pwd = 'root';

$pdo = new \Slim\PDO\Database($dsn, $usr, $pwd);

try { $selectStatement = $pdo->query('SELECT * FROM hotels ORDER BY REPLACE(name, "The ", "")'); } catch(Exception $e) { echo $e->getMessage(); die(); };

$data = $selectStatement->fetchAll(PDO::FETCH_ASSOC);

$app->run(); ?>

'''

And here is a part in my home.twig file which contains a dropdown menu with the $data items that I want to display.

''' <div id="dropdownmob"> <select class="select" onchange="location = this.options[this.selectedIndex].value;"> <option>Select an item</option> <optgroup label="A-Z"> <?php foreach($data as $items){ echo '<option value="items.php?id='.$items["id"].'">' .$items["name"].'</option>'; } ?> </select> </div> '''

Obviously, it doesn't work right now because before, my home.twig file was my initial index.php file without slim/twig.

Help me, I'm lost :(
