Using CakePhp 4.4.11
In my controller I have:
$languages = Hash::extract($user->languages, '{n}.name');
But when going to the page, I get: Class 'App\Controller\Hash' not found
Am I supposed to install something?
You are missing the use statement at the top. Your IDE should help you with that usually.
something like use Cake\Utility\Hash;
So I put it in both AppController and UserController and am still getting the same error.

Then you added it wrong. We can’t say exactly what you did that was wrong, as you haven’t shown us what you added or where. But this is not a “CakePHP issue”, it’s basic PHP. Cake docs assume a basic level of competence with PHP, maybe do a bit of reading on PHP namespaces to understand this better.
I added it to the top of the AppController.php file under:
<?php
declare(strict_types=1);

namespace App\Controller;
use Cake\Controller\Controller;
use Cake\Utility\Hash;
Under UserController.php, I have:
public function view($id = null)
{
$user = $this->Users->get($id, [
'contain' => ['Countries', 'Languages'],
]);
$languages = Hash::extract($user->languages, '{n}.name');
$this->set(compact('user'));
$this->set(compact('languages'));
}
use statements are not shared across PHP files. they need to be defined per PHP file.
You need to add the use statement in your UserController file.
Since it seems you don’t know how namespaces work I’d recommend you watch this:
