Custom class not found in a Laravel app - php

I've had to try and work with an older package meant for php into my Laravel project.
I've added two custom classes, both are in the same folder "Classes" under the main "app" folder in my Laravel project.
One of these classes is recognized from a generated controller for my Laravel project. My paymentsController has use App\Classes\Quickbooks_Payments; in the top.
However, going to that Classes' file, I hit the following error through a route leading to my controller:
Class 'App\Classes\Quickbooks_Loader' not found
Now this is where this above is referenced in my paymentsController file:
<?php
namespace App\Classes\Quickbooks_Payments;
use App\Classes\Quickbooks_Loader;
/**
* QuickBooks Payments class
*
*/
/**
* Utilities class (for masking and some other misc things)
*/
QuickBooks_Loader::load('/QuickBooks/Utilities.php');
This last line is where the above error is referenced. And I do have both the Quickbooks_Loader.php and the Quickbooks_Payments.php in the same folder. My Quickbooks_Loader.php file starts off as such:
<?php
namespace App\Classes\QuickBooks_Loader;
So I know this is likely because of my inexperience with custom/imported classes. What am I doing wrong and how should I properly "import" these custom classes and have them recognized without any issues?

Change namespace in both classes you've shown to:
namespace App\Classes;
And run composer du
Also, make sure the class looks like this and not like you've shown (I'm not sure about did you cut something or not):
<?php
namespace App\Classes;
use App\Classes\Quickbooks_Loader;
class Quickbooks_Payments
{
public function __construct()
{
dd('It\'s working!');
}
}

How to use a custom class in Laravel when it is in a sub-folder?

In my new laravel app I've added two custom classes. One loads fine when I use it in the controller, but the other, which is in another folder, does not work.
The working class, which I will call Working is located in app\Classes, it has the namespace namespace App\Classes and in the controller I call it with use App\Classes\Working.
The non-working class, which I will call NonWorking is located in app\Classes\NonWorking. I've tried giving it the namespaces namespace App\Classes and namespace App\Classes\NonWorking. From the controller I've tried calling it with use App\Classes\NonWorking and use App\Classes\NonWorking\NonWorking, but I get the error Class 'App\Classes\NonWorking' not found or Class 'App\Classes\NonWorking\NonWorking' not found.
I've been able to get it to run correctly by moving the NonWorking class into the same folder as the Working class and setting the namespace as namespace App\Classes, but the NonWorking class is from another repo and should be in its own folder as it will not be the only one from another repo.
So, how do I get Laravel to understand where this class is?
Laravel uses the PSR-4 autoloading. What it means is basically your class should follow the folder structure.
So if you have classes in app/Classes, they should have the namespace App\Classes.
So the file app/Classes/Working.php will have at its top namespace App\Classes; and to import it in another file, you write in the other file use App\Classes\Working;
If you have a class inside app/Classes/SubFolder, it should have the namespace namespace App\Classes\SubFolder;
So here is a class AmazingClass in app/Classes/SubFolder/AmazingClass.php file:
// app/Classes/SubFolder/AmazingClass.php
namespace App\Classes\SubFolder;
class AmazingClass
{
//
}
Let's use AmazingClass in another class.
// Some file in another namespace
namespace App\My\Random;
use App\Classes\SubFolder\AmazingClass;
// Rest of the file
Plus: Whenever you add a new class and you can't use it, it's likely that it's not autoloaded. Run the command
composer dump-autoload
to re-autoload the classes.
to solve your issue just create your folders and classes in App folder and run command :
composer dump-autoload
and they load all classes you have created

Trait not found error magento2

I am installing a module, where I am getting the error when
running
php bin/magento setup:di:compile.
The error is like:
Fatal error: Trait 'Niks\LayeredNavigation\Model\Layer\Filter\SliderTrait'
not found in /var/www/clients/client2/web202/web/app/code/NIKS
/LayeredNavigation/Model/Layer/Filter/Decimal.php on line 10
When I check the Decimal.php the code is like
<?php
namespace Niks\LayeredNavigation\Model\Layer\Filter;
use Magento\CatalogSearch\Model\Layer\Filter\Decimal as CoreDecimal;
/**
* Layer attribute filter
*/
class Decimal extends CoreDecimal
{
use SliderTrait; //This is relevant line 10 referred in code
...
and in the file SliderTrait.php it is like:
<?php
namespace Niks\LayeredNavigation\Model\Layer\Filter;
use Magento\Framework\App\ObjectManager;
use Magento\Store\Model\StoreManagerInterface;
trait SliderTrait
{
/** #var \Niks\LayeredNavigation\Model\ResourceModel\Fulltext\Collection|null */
protected $_skipFilterCollection;
...
so to me the code looks okay and am not able to find any issue, why this error is generated.
I can see that your vendor folder name is "NIKS", compared to the vendor namespace "Niks". It seems like Magento 2 folder structure is case sensitive inside /app/code for autoloading classes. Either change the namespace to "NIKS", or the folder name to "Niks". That should solve it!

Laravel Class 'App\FBLogin\authlogin' not found

I created a new FBLogin.php file in App Folder, added class:
namespace App\FBLogin;
class authlogin {}
Now i want to use this class in my Controller File, so i added:
use App\FBLogin\authlogin;
Now when i am trying to use this class authlogin, it is showing me error Class 'App\FBLogin\authlogin' not found
Is there something i am doing wrong?
Laravel Version: 5.5
Why would you use a lowercase format when naming your classes? Anyway, your namespace inside your app folder should follow your file structure.
If you create your class like below,
namespace App\FBLogin;
class authlogin {
// code here
}
Your file structure must be:
app/
FBLogin/
authlogin.php
Then you can use the class anywhere in your app by declaring the proper namespace
use App\FBLogin\authlogin;
$authlogin = new authlogin();

how laravel extends class without including them

I encountered the topic called 'namespace' in php after I started working with Laravel. While trying to understand namespace I found that to extend a class under a namespace, I need to include that class in my current page. Like the following:
directory '..\teacher\Teacher.php'
namespace Teacher;
class Teacher{
public $headTeacher='mr X';
}
to extend the calss i need to include that page as well as use the namespace
directory '..\studnet\student.php'
use \Teacher\Teacher; //use the namespace
include('../teacher/Teacher.php'); // include the page
class mathTeacher extends Teacher{
public function headTeacherName(){
echo $this->headTeacher;
}
}
$student=new mathTeacher();
$student->headTeacherName();
I am wondering how Laravel only use namespace to include classes. Like if I create a controller called 'userController'. The structure of the page is
namespace App\Http\Controllers;
class userController extends Controller{
}
They never included the php page which holds the 'controller' class. But they were able to extend it somehow. Also I can use "View" ,"Auth" just by using the use View or use Auth command. How is it done? How can I implement the same with the code I have provided? Thanks in advance.
Laravel uses composer.php for autoloading the classes. All classes in the autoload directory will be pre loaded. So you can just use the namespace and consume anywhere across the application.
Learn more about composer, composer config can be found on composer.json in your root path for the application

Attempted to load class "ClassName" from namespace (...). Even though namespace is imported

I have a Symfony project to which I added some non-symfony php files containing various classes. But for some reason the classes are not loaded when loading the website, even though the IDE sees them properly.
So, I have a class that needs other classes:
namespace rootspace\FrontBundle\Controller;
use rootspace\FrontBundle\Networks\TwitterOAuth;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Template;
class TwitterController extends Controller
{
public function connectAction(){
// The TwitterOAuth instance
$connection = new TwitterOAuth('abc', '123');
}
}
And then the class which fails to load (that needs yet another file)
namespace rootspace\FrontBundle\Networks;
/* Load OAuth lib. You can find it at http://oauth.net */
//require_once('OAuth.php'); -- should this be commented out?
/**
* Twitter OAuth class
*/
class TwitterOAuth {
/* Contains the last HTTP status code returned. */
}
Lastly, the third file
namespace rootspace\FrontBundle\Networks;
use Symfony\Component\Config\Definition\Exception\Exception;
class OAuthConsumer
{
public $key;
public $secret;
}
(...)
I assume the actual filenames don't matter, right? Nor their structure? PhpStorm sees all the classes properly, I can right-click through them, but it fails when deployed.
Thanks for help
Edit - the whole error message says
Attempted to load class "TwitterOAuth" from namespace "rootspace\FrontBundle\Networks" in D:\Dropbox\project\src\rootspace\FrontBundle\Controller\TwitterController.php line 15. Do you need to "use" it from another namespace?
This is because Symfony's autoloader follows PSR standards (PSR-0, PSR-4) which says that fully qualified (with namespace) class name translates to file location and name. So in fact file names does matter.
So in your case rootspace\FrontBundle\Networks\TwitterOAuth class should be located in rootspace/FrontBundle/Networks directory in file called TwitterOAuth.php
If classes you are using does not follow PSR standards you can also register them manually in app/autoloader.php file
