Hi. I’m new here and new to Slim in fact… I’m learning through here [https://www.youtube.com/watch?v=0hKciR\_dJAk&list=PLfdtiltiRHWGc\_yY90XRdq6mRww042aEC&index=12](https://www.youtube.com/watch?v=0hKciR_dJAk&list=PLfdtiltiRHWGc_yY90XRdq6mRww042aEC&index=12) (minute 5:45)  
But I found that this video was made in 2016 and when I try to emulate all of that, I got some deprecated functions and classes… so, I am kinda lost about how to implement this:

namespace App\Middleware;

class ValidationErrorsMiddleware extends Middleware  
{  
public function \_\_invoke($request, $response, $next)  
{  
this-\>container-\>view-\>getEnvironment()-\>addGlobal('errors', \_SESSION[‘errors’]);  
unset($\_SESSION[‘errors’]);

```
    $response = $next($request, $response);
    return $response;
}

```

}

But, getEnvironment and addGlobals are deprecated… so, I search in slim framework page but even it’s mentioned I don’t get how to use other options to make this work…

**Message:** Call to undefined method Slim\Views\Twig::environment()  
or if I delete getEnvironment  
**Message:** Call to undefined method Slim\Views\Twig::addGlobal()

Do anyone could tell me what I need to use and where I can find information up today?

Slim 3 is current version and 4 is in Beta

Yes, I’m using Slim 3, but as I saw it, those are Slim 2 methods and now deprecated, but don’t know how to jump from Slim2 to Slim 3 with same functionality but not deprecated methods.

Yes, of course… this is in my app.php in my bootstrap directory

$container = $app-\>getContainer();

$container[‘view’] = function ($container) {  
$view = new \Slim\Views\Twig( **DIR**. ‘/…/resources/views’, [  
‘cache’ =\> false,  
]);  
$view-\>addExtension(new \Slim\Views\TwigExtension(  
$container-\>router,  
$container-\>request-\>getUri()  
));  
return $view;  
};

can you provide entire error message and backtrace?  
this is weird; your error message is about undefined method `environment()`  
but the method name (and your code) should be method `getEnvironment()`

Yes, sorry… I try so many times to understand the error, that I copied environment() once instead of getEnvironment().

Anyway searching I found a way to bypass the problem, using the TwigExtension like here [http://help.slimframework.com/discussions/questions/954-twig-getenvironment-function-no-longer-available-using-slim-views](http://help.slimframework.com/discussions/questions/954-twig-getenvironment-function-no-longer-available-using-slim-views)

$view-\>parserExtensions = array(  
new \Slim\Views\TwigExtension(),  
);  
$app-\>view-\>setTemplatesDirectory( dirname( **FILE** ) . ‘/Views’);

$twig = $app-\>view()-\>getEnvironment();  
$twig-\>addGlobal(‘test’, ‘Slim Awesomeness!’);

I am a little concern to move from Slim 2 to 3 (then to 4) with this course, wish I could find the correct way. Thanks for the help @jDolba

In Slim 4:

`$twig->addGlobal('test', 'Slim Awesomeness!');`

becomes:

`$twig->getEnvironment()->addGlobal('test', 'Slim Awesomeness!');`
