Laravel: Controller does not exist - laravel-4

Question

I added new controller in /app/controllers/admin/ folder and added the route in /app/routes.php file as well. Then i run the following command to autoload them
php artisan dump-autoload
I got the following error
Mcrypt PHP extension required.
I followed instruction given at https://askubuntu.com/questions/460837/mcrypt-extension-is-missing-in-14-04-server-for-mysql and able to resolve the mcrypt issue.
After that i run the php artisan dump-autoload command but still getting following error
{"error":{"type":"ReflectionException","message":"Class CoursesController does not exist","file":"\/var\/www\/html\/vendor\/laravel\/framework\/src\/Illuminate\/Container\/Container.php","line":504}}
Here is code of my routes.php file
Route::group(array('before' => 'adminauth', 'except' => array('/admin/login', '/admin/logout')), function() {
Route::resource('/admin/courses', 'CoursesController');
Route::resource('/admin/teachers', 'TeachersController');
Route::resource('/admin/subjects', 'SubjectsController');
});
Here is code of CoursesController.php file
<?php
class CoursesController extends BaseController
{
public function index()
{
$courses = Course::where('is_deleted', 0)->get();
return View::make('admin.courses.index', compact('courses'));
}
public function create()
{
return View::make('admin.courses.create');
}
public function store()
{
$validator = Validator::make($data = Input::all(), Course::$rules);
if ($validator->fails()) {
$messages = $validator->messages();
$response = '';
foreach ($messages->all(':message') as $message) {
$response = $message;
}
return Response::json(array('message'=>$response, 'status'=>'failure'));
} else {
Course::create($data);
return Response::json(array('message'=>'Course created successfully','status'=>'success'));
}
}
public function edit($id)
{
$course = Course::find($id);
return View::make('admin.courses.edit', compact('course'));
}
public function update($id)
{
$course = Course::findOrFail($id);
$validator = Validator::make($data = Input::all(), Course::editRules($id));
if ($validator->fails()) {
$messages = $validator->messages();
$response = '';
foreach ($messages->all(':message') as $message) {
$response = $message;
}
return Response::json(array('message'=>$response, 'status'=>'failure'));
} else {
$course->update($data);
return Response::json(array('message'=>'Course updated successfully','status'=>'success'));
}
}
public function destroy($id)
{
Course::findOrFail($id)->update(array('is_deleted' => '1'));
return Response::json(array('message'=>'Course deleted successfully','status'=>'success'));
}
}

Answer 1

Did you add autoload classmap to composer.json file?
Open your composer.json file and add
"autoload": {
"classmap": [
"app/controllers/admin",
]
}
if you add folders inside controllers, you need to add it to composer.json file. Then run
composer dumpautoload
OR ALTERNATIVE
go to app/start/global.php and add
ClassLoader::addDirectories(array(
app_path().'/controllers/admin',
));

2021 answer (Laravel 8.5)
In your controller;
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use App\Providers\RouteServiceProvider;
use Illuminate\Http\Request;
class AuthController extends Controller
{
public function login(Request $request){
return "login";
}
}
In your routes;
use App\Http\Controllers\AuthController;
Route::post('/login', [AuthController::class, 'login']);

Answer 3

In my case, in the top of my controller code i add this line :
namespace App\Http\Controllers\CustomFolder\ControllerClassName;
and my problem is solved

Answer 4

We can create controller via command line.
php artisan make:controller nameController --plain.
Before Laravel 5, make namespace is not available. Instead, this works
php artisan controller:make nameController
Execute your command inside your project directory and then create your function.

Answer 5

Don't forget to do:
php artisan route:clear
In my case this was the solution when I got this error after making a route code change.

Answer 6

In my case, I had to change the route file from this:
Route::get('/','SessionController#accessSessionData');
to this:
Route::get('/','App\Http\Controllers\SessionController#accessSessionData');
then clearing the cache with this:
php artisan route:clear
made things work.

Answer 7

A bit late but in my experience adding this to the RouteServiceProvider.php solves the problem
protected $namespace = 'App\Http\Controllers';

Answer 8

I think your problem has already been fixed. But this is what did.
Structure
Http
.Auth
.CustomControllerFolder
-> CustomController.php
to get this working
in your route file make sure you use the correct name space
for eg:
Route::group(['namespace'=>'CustomControllerFolder','prefix'=>'prefix'],
function() {
//define your route here
}
Also dont forget to use namespace App\Http\Controllers\CustomControllerFolder in your controller.
That should fix the issue.
Thanks

Answer 9

I just had this issue because I renamed a file from EmployeeRequestContoller to EmployeeRequestsContoller, but when I renamed it I missed the .php extension!
When I reran php artisan make:controller EmployeeRequestsContoller just to be sure I wasn't going crazy and the file showed up I could clearly see the mistake:
/EmployeeRequestsContoller
/EmployeeRequestsContoller.php
Make sure you have the extension if you've renamed!

Answer 10

I use Laravel 9 this is the way we should use controllers
use App\Http\Controllers\UserController;
Route::get('/user', [UserController::class, 'index']);

Answer 11

Sometimes we are missing namespace App\Http\Controllers; on top of our controller code.

Answer 12

In my case, I have several backup files of admin and home controllers renamed with different dates and we ran a composer update on top of it and it gave us an error
after I removed the other older controller files and re-ran the composer update fixed my issue.
- Clue - composer update command gave us a warning.

Answer 13

Use full namespace inside web.php
Route::resource('myusers','App\Http\Controllers\MyUserController');
