Laravel Class Not Found FatalErrorException - php

Here is the error I see.
Class 'A\B\C\D\F\ETypeRequiredException' not found
What I Tried
composer dump
composer dump-autoload & composer dump-autoload -o
Moved the class to A\B\C\D\R and voala! It is working.
Moved back and again, not working.
Code Snippets
The page I see the error:
<?php namespace A\B\C\D\R;
use A\B\C\D\EInterface;
use A\B\C\D\F\ETypeRequiredException;
class E implements EInterface
protected function foo()
{
if(empty($this->bar)) { throw new ETypeRequiredException("Bar is undefined."); }
}
The Page That Never Loaded
<?php namespace A\B\C\D\F;
class ETypeRequiredException extends \UnexpectedValueException {}

If you are using psr-0 to resolve your namespaces:
"psr-0": {
"X": "app"
}
You should be aware that it will use you path structure, so
ETypeRequiredException
Should be put in
app/A/B/C/D/F/ETypeRequiredException.php

Class Not Found in PHP Laravel 6.x when another class extends

I always get the class not found exception in php laravel 6 when i create a class and extend a parent class named A which is located in the same directory.
However, another child class that is located in same directory could extend class A successfully.
In addition, i couldn't also instantiate the class A due to class not found exception in another .php file.
Please help me on this.
Thanks in an advance.
Parent class: myContext
<?php
namespace config\models;
class myContext {
public static $conn;
...
}
Class myUser: extension is fine.
<?php
namespace config\models;
class myUser extends myContext {
private $name;
...
}
Class oauth: extension returns myContext class not found.
<?php
namespace config\models;
class oauth extends myContext {
private $user;
}
Instantiate the class - returns class not found.
<?php
use config\models\myContext as context;
$cont = new context();
Check whether the namespace is added correctly when the parent class is imported.

Laravel 6: Class 'Form' not found
To get the provided example codes to work you need to use require_once
<?php
require_once('models/myContext.php');
use app\config\models\myContext as context;
$test = new context();
A search on SO brought me to this source
You try to add this line of code in the composer.json file, then execute the composer dumpautoload command on the command line
In composer.json file,
"autoload": {
"psr-4": {
"App\\": "app/",
"config\\models\\": "config/models"
},
"classmap": [
"database/seeds",
"database/factories"
]
},
After that composer dump-autoload.
have you add autoload for config/ folder in composer.json. Laravel only default autoload for app/

CakePHP class not found using a custom class

I just started using CakePHP 3. I'm trying to get up and running but doing the simplest of things is proving to be a headache.
I have a class, MySimpleClass, in src/App/MySimpleClass.php
<?php
namespace MyApp\MyNamespace;
class MySimpleClass {
public function aSimpleFunction() {
return 1;
}
}
And in my controller:
<?php
namespace App\Controller;
use Cake\Controller\Controller;
use MyApp\MyNamespace\MySimpleClass;
class MyFirstController extends Controller {
public function display() {
$mySimpleClass = new MySimpleClass();
echo $mySimpleClass->aSimpleFunction();
}
}
But this always gives me:
Error in: ROOT/src/Controller/TestController.php, line 10 Class 'MyApp\MyNamespace\MySimpleClass' not found
I use bin/cake server to run the HTTP server
I added App::className('MyApp\MyNamespace\MySimpleClass'); to bootstrap.php to see if that'd make a difference but it doesn't.
I've run composer dump-autoload on several occasions.
I tried putting MySimpleClass into global namespace but it still gave me the error.
PHPStorm isn't giving me any syntax or naming errors.
You should place your controllers in:
src/Controller
and use:
namespace App\Controller;
Nevermind, I finally found the solution...
I just had to add src to the classmap in composer.json:
"autoload": {
"classmap": [
"src"
],
...,
}
Edit:
Instead of abusing classmap, I just moved my class files to a directory outside of src
If your class is in the file src/App/MySimpleClass.php, the namespace has to be App\App. The first App refers to the root namespace of every CakePHP 3.x application, the second App refers to the subdirectory within the src directory you put your class file into.
If the namespace of the class should be App\MyNamespace, your classfile has to be located in src/MyNamespace.
Also: according to the error message you quoted, your MyFirstController is in a file called TestController.php. Instead, it should be MyFirstController.php. I recommend giving https://book.cakephp.org/3.0/en/intro/conventions.html#file-and-class-name-conventions a read regarding this topic.

PHP adding custom namespace using autoloader from composer

Here is my folder structure:
Classes
- CronJobs
- Weather
- WeatherSite.php
I want to load WeatherSite class from my script. Im using composer with autoload:
$loader = include(LIBRARY .'autoload.php');
$loader->add('Classes\Weather',CLASSES .'cronjobs/weather');
$weather = new Classes\Weather\WeatherSite();
Im assuming the above code is adding the namespace and the path that namespace resolves to. But when the page loads I always get this error:
Fatal error: Class 'Classes\Weather\WeatherSite' not found
Here is my WeatherSite.php file:
namespace Classes\Weather;
class WeatherSite {
public function __construct()
{
}
public function findWeatherSites()
{
}
}
What am I doing wrong?
You actually don't need custom autoloader, you can use PSR-4.
Update your autoload section in composer.json:
"autoload": {
"psr-4": {
"Classes\\Weather\\": "Classes/CronJobs/Weather"
}
}
To explain: it's {"Namespace\\\": "directory to be found in"}
Don't forget to run composer dump-autoload to update Composer cache.
Then you can use it like this:
include(LIBRARY .'autoload.php');
$weather = new Classes\Weather\WeatherSite();

Fatal error class MainController not found

so i have the following structure for what i'm trying to target but what i'm getting is the Fatal error class MainController not found , i'm new to autoload and namespace thing (but getting into them fast) i just need to know why this is happening , hope you guys have bit explained situation for me? i did saw few of answer around stackoverflow but nuthing helped, i know i'm doing something really wrong, but thats how i will learn :). structure:
composer.json
src/controllers/MainController.php
the following is my autoload inside composer.json file:
"autoload": {
"psr-4": {
"controllers\\": "src/controllers/"
}
}
and this is how my MainController.php looks alike :
namespace MainController;
class MainController{
function test($name){
echo 'holaaaa'.$name;
}
}
controller call inside: app/loads/loadController.php :::
use MainController;
$MainController = new MainController();
more info on vendor/autoload.php
it's included inside : index.php and inside index.php i have included mainapp.php and inside mainapp.php i have included loadcontroller.php vich calls the controller
structure screenshot:
Okay, in your Composer file you say the namespace is controllers. In your PHP file you say the namespace is MainController. They need to be the same for the autoloading to work.
If we are to go by your Composer file then the PHP should look like this:
namespace controllers;
class MainController {}
And the class should be called like this:
$MainController = new \controllers\MainController;
Or like this:
use controllers\MainController;
$MainController = new MainController;
Or, if you want a nicer-looking class name:
use controllers\MainController as Controller;
$MainController = new Controller;
In my case I only managed to correct it after deleting my folder from the composer (vendor) and rerunning the command composer dump-autoload

Laravel 4 - Repository Interface not found

Just started working through laracasts and trying to move on from direct eloquent use in the controllers.
I have implemented everything that I need to but hitting this error:
Class tva\Repositories\VehicleRepositoryInterface does not exist
My folder structure is:
app/
tva/
repositories/
VehiclesController:
use tva\Repositories\VehicleRepositoryInterface;
class VehiclesController extends \BaseController {
protected $vehicle;
public function __construct(VehicleRepositoryInterface $vehicle)
{
$this->vehicle = $vehicle;
}
}
In the repositories folder:
VehicleRepository:
namespace tva\Repositories;
class VehicleRepository implements VehicleRepositoryInterface {
}
VehicleRepositoryInterface:
namespace tva\Repositories;
interface VehicleRepositoryInterface {
}
And also updated my composer.json:
"psr-0": {
"tva": "app/"
},
To me, this should work?
Issue solved, instead of using psr-0 I added the directory to the classmap and all issues solved.
