Laravel does not recognize the PHP class of Blade components

Hi, I need help!

I develop my Laravel applications using Windows with Laravel Homestead. In Laravel Homestead I am using PHP 8.0.21 and Laravel 9.23.

I deployed my project to a host without any errors. However, Laravel does not recognize the PHP class of Blade components, making it impossible to use the application.

It is as if the component were anonymous. I put a dd('hi') in the class construct and nothing happens.

I cleared all Laravel caches using artisan optimize:clear. I cleared all server caches. I checked access permissions. Nothing solved, still not being able to use the application.

In my local environment the application works, but in hosting it doesn't. I don't know what else to check as there is no error log.

The hosting PHP version is 8.0.20, I don't believe that's the reason for the problem.

Can you help me?

@Sinnbeck I use the component's PHP class to get records from the database, so the error is that the blade component's variables are not populated and Laravel doesn't recognize the variable. That's why I commented that it seems that laravel is understanding that the component is anonymous, that is, without class. I put a dd() in the component class construct but nothing happens, that black screen should appear.

@jader it could be a problem with casing. If your dev computer is windows or Mac , it isn't case sensitive. Linux is.

Check the name of the class and class file

@jader does the class have a namespace? It's cut from the image. You can just copy paste it

@jader I'm thinking that laravel might look for proper namespace based on StudlyCase. Try changing the class folders and namespaces to this

I would give an example, but I cannot copy from images

Edit: just saw @martinbean said the same thing below

@jader Not related to the error, but the following is somewhat pointless:

$this->menus = collect(Menu::with(['parent', 'childs'])->orderBy('order')->get())->toArray();

Since Menu::get() already returns a collection, there’s no need to collect() anything – especially not if you don’t even use the collection, but just convert it to an array. But why convert it to an array at all? This will do the same, but more simply (and with the extra functionality of a collection instead of an array):

class SidebarMain extends Component {
	public Collection $menus;

	public function __construct() {
		$this->menus = Menu::with(['parent', 'childs'])->orderBy('order')->get();
	}
}

@Sinnbeck only now i figured out how to insert the code here, I will make the changes you suggested...

<?php

namespace App\View\Components\admin\sidebar;

use App\Models\Menu;
use Illuminate\View\Component;

class SidebarMain extends Component
{
    /**
     * Menus da área administrativa.
     *
     * @var array
     */
    public array $menus;

    /**
     * Create a new component instance.
     *
     * @return void
     */
    public function __construct()
    {
        $this->menus = collect(Menu::with(['parent', 'childs'])->orderBy('order')->get())->toArray();
    }

    /**
     * Get the view / contents that represent the component.
     *
     * @return \Illuminate\Contracts\View\View|\Closure|string
     */
    public function render()
    {
        return view('components.admin.sidebar.sidebar-main');
    }
}

@jader I am talking about this namespace (and folders as well)

namespace App\View\Components\Admin\Sidebar;

@Sinnbeck Wow, it worked perfectly. I learned a good lesson today, as I've been trying to solve this for 10 days. Thank you very much for your time and willingness to help me.

@jader You should be using StudlyCase for class names, because I imagine Laravel will be trying to “guess” the class name and namespace from the view name.
