Slim Framework 3. How to set $baseURL for all views to use?

Question

I could get and set $baseUrl like this in every route,

<?php
$app->get('/sign-in', function ($request, $response, $args) {
    $uri = $request->getUri();
    $baseUrl = $uri->getBaseUrl();

    $this->renderer->render($response, 'sign-in.phtml', $args);
});

But I have to set it in every route for all views.

Is there a way where I can set $baseUrl in a place and use it in every routes/views ?

In index.php, environment values are already set. like `$_ENV['SLIM_MODE'] = "local";`. if you set local means edit your local.config.php file like `ConfigHelper::write('baseUrl', "http://yyyyyyyy.com");` — Mansoor H, Aug 28 '16 at 09:05
@MansoorH Sorry, I don't understand. I search through the whole slim skeleton for the terms 'SLIM_MODE', it does not exist anywhere. Can't find local.config.php either. — Jacob Goh, Aug 28 '16 at 09:11

@JacobGoh Router Class has a `setBasePath` method. Use that. https://github.com/slimphp/Slim/blob/3.x/Slim/Router.php#L95 — Shivam Mathur, Aug 29 '16 at 04:05

When you register the Twig View helper, also add the $view['baseUrl'] so you can use it in every route:

$container['view'] = function ($c) {
    $view = new \Slim\Views\Twig('templates');

    // Instantiate and add Slim specific extension
    $basePath = rtrim(str_ireplace('index.php', '', $c['request']->getUri()->getBasePath()), '/');
    $view->addExtension(new Slim\Views\TwigExtension($c['router'], $basePath));
    $view['baseUrl'] = $c['request']->getUri()->getBaseUrl();

    return $view;
};

In your Twig file you'll use:

{{ baseUrl }}
