Class App\Http\Controllers\UserController 不存在

Question

Having the issue when loading the route /users or /user/add and being return an error of;

ReflectionException in Route.php line 280: Class App\Http\Controllers\App\Controllers\UserController does not exist

The UserController does exist and it is not in a folder within my controllers folder.

My route file;

Route::group(['middleware' => 'auth'], function(){
    Route::get('/route/selector', 'PagesController@selectRoute');

    // Admin Only //
    Route::group(['middleware' => 'isAdmin'], function(){
        Route::get('/admin', 'AdminController@index');

        Route::get('/users', 'UserController@index');
        Route::get('/user/add', 'UserController@getAdd');
        Route::post('/user/add', 'UserController@postAdd');
        Route::get('/user/edit/{id}', 'UserController@getEdit');
        Route::post('/user/edit/{id}', 'UserController@postEdit');
        Route::get('/user/delete/{id}', 'UserController@delete');
    });
});

My UserController;

<?php

namespace App\Http\Controllers;

use App\Http\Requests;
use App\User;
use App\UserTypes;

use Auth;
use Hashids;
use Redirect;
use Request;
use Hash;

class UserController extends Controller
{
    public function index(){
        $users = User::get();
        return view('users.index', compact('users'));
    }

    public function getAdd(){
        $user_type = UserTypes::pluck('user_type', 'id');
        return view('users.add', compact('user_type'));
    }

    public function postAdd(){
        $input = Request::all();
        $password = str_random(8);
        User::create(
            'email' => $input['email'],
            'password' => Hash::make($password),
            'first_name' => $input['first_name'],
            'surname' => $input['surname'],
            'phone_number' => $input['phone_number'],
            'user_type' => $input['user_type'],
        );

        return Redirect::action('UserController@index');
    }

    public function getEdit($id){

    }

    public function postEdit($id){

    }

    public function delete($id){
        User::find(current(Hashids::decode($id)))->delete();
        return Redirect::action('UserController@index');
    }

}

When I remove the User::create(); part the error disappears, will it have something to do with this?

Answer 1

Laravel 8.x update has a different way of using routes.

Previously it was:

Route::get('/', 'PagesController@index');

Now it has changed to

Route::get('/',[PagesController::class, 'index']);

Note: don't forget to import (use) your controller in the routes(web.php) file at the top. Like:

use App\Http\Controllers\PagesController;

Answer 2

Replace this code

Route::group(['middleware' => 'isAdmin'], function(){
    Route::get('/admin', 'AdminController@index');

    Route::get('/users', 'UserController@index');
    Route::get('/user/add', 'UserController@getAdd');
    Route::post('/user/add', 'UserController@postAdd');
    Route::get('/user/edit/{id}', 'UserController@getEdit');
    Route::post('/user/edit/{id}', 'UserController@postEdit');
    Route::get('/user/delete/{id}', 'UserController@delete');
});

with this

Route::group(['middleware' => 'isAdmin'], function(){
    Route::get('/admin', 'AdminController@index');
    Route::group(['namespace' => YOUR_NAMESPACE], function(){
        Route::get('/users', 'UserController@index');
        Route::get('/user/add', 'UserController@getAdd');
        Route::post('/user/add', 'UserController@postAdd');
        Route::get('/user/edit/{id}', 'UserController@getEdit');
        Route::post('/user/edit/{id}', 'UserController@postEdit');
        Route::get('/user/delete/{id}', 'UserController@delete');
    });
});

& in your UserController you should correct your namespace also

eg your UserController resides in app/Controllers directory then your UserController will be like this

<?php

namespace App\Controllers;

use App\Http\Requests;
use App\User;
use App\UserTypes;

use Auth;
use Hashids;
use Redirect;
use Request;
use Hash;

class UserController extends Controller
{
    public function index(){
        $users = User::get();
        return view('users.index', compact('users'));
    }

    public function getAdd(){
        $user_type = UserTypes::pluck('user_type', 'id');
        return view('users.add', compact('user_type'));
    }

    public function postAdd(){
        $input = Request::all();
        $password = str_random(8);
        User::create(
            'email' => $input['email'],
            'password' => Hash::make($password),
            'first_name' => $input['first_name'],
            'surname' => $input['surname'],
            'phone_number' => $input['phone_number'],
            'user_type' => $input['user_type'],
        );

        return Redirect::action('UserController@index');
    }

    public function getEdit($id){

    }

    public function postEdit($id){

    }

    public function delete($id){
        User::find(current(Hashids::decode($id)))->delete();
        return Redirect::action('UserController@index');
    }

}

& your route will be like this

Route::group(['middleware' => 'auth'], function(){
    Route::get('/route/selector', 'PagesController@selectRoute');

    // Admin Only //
    Route::group(['middleware' => 'isAdmin'], function(){
        Route::get('/admin', 'AdminController@index');
        Route::group(['namespace' => '\App\Controllers'], function(){
            Route::get('/users', 'UserController@index');
            Route::get('/user/add', 'UserController@getAdd');
            Route::post('/user/add', 'UserController@postAdd');
            Route::get('/user/edit/{id}', 'UserController@getEdit');
            Route::post('/user/edit/{id}', 'UserController@postEdit');
            Route::get('/user/delete/{id}', 'UserController@delete');
        });
    });
});

Answer 3

The create method is missing the array brackets.

User::create([
    'email' => $input['email'],
    'password' => Hash::make($password),
    'first_name' => $input['first_name'],
    'surname' => $input['surname'],
    'phone_number' => $input['phone_number'],
    'user_type' => $input['user_type'],
]);

Answer 4

use App\\Http\\Controllers\\UserController;

Route::get('/user', [UserController::class, 'index]);

Laravel 8 has updated the route format. above route will only only for laravel 8 or higher

if you laravel below 8 try using

Route::get('/user', 'UserController@index');

Answer 5

Don't forget to add this line to your controller

use App\Http\Controllers\Controller;

If this is not present in your controller your controller is not able to extend the features of the main Laravel controller prototypes

Answer 6

this happen because you are missing Controller class which has extends for it and others reasons depended on your actions.

to solve this problem you need to use Controller class in your UserController .

use App\Http\Controllers\Controller;

or you can easily avoiding that be type on the console

php artisan make:controller UserController

that will solving the problem.

Answer 7

Laravel 8 updated the Route format, please try the updated format on controllers routes.

use App\\Http\\Controllers\\UserController;

Route::get('/user', [UserController::class, 'index']);

Fixed.

Answer 8

Route::get('/', 'api\AppController@appInfo');

I created AppController in controller/api folder so this is my path. You need to give path till your controller.

Answer 9

DOCS Laravel 8.x controllers#resource-controllers

On file routes/web.php

use App\\Http\\Controllers\\UserController; and then Route::resource('user',UserController::class);

Answer 10

in laravel 8 do the following remove the comment from RouteServiceProvider.php First of all Open RouteServiceProvider.php located at app\\Providers\\RouteServiceProvider.php

Now remove comment of following line.

protected $namespace = 'App\\Http\\Controllers';

Answer 11

Actually You are getting 2 errors, the last one gets shown on the top of the page, and that error is that the controller does not exist. The reason why you are seeing that error is because the Model::create() method expects an array of attributes, whilst you are calling it with separate arguments instead.

Try:

$user = User::create([
    'email' => $input['email'],
    'password' => Hash::make($password),
    'first_name' => $input['first_name'],
    'surname' => $input['surname'],
    'phone_number' => $input['phone_number'],
    'user_type' => $input['user_type'],
]);

Answer 12

be sure to type correctly use App\Http\Controllers\Controller; as my mistaken was with incorrect typing of use App\Http\Controller\Controller;

just instead of controllers/controller I mistakenly missed s at the end of controllers/controller and I typed controller/controller which was incorrect.

Answer 13

The best solution for this problem is to open the file "Providers/RouteServiceProvider" and edit it. But, first, add it to the RouteServiceProvider class.

protected $namespace = 'App\Http\Controllers';

Next, in the boot() function.

$this->configureRateLimiting();

$this->routes(function () {
    Route::middleware('api')
        ->prefix('api')
        ->group(base_path('routes/api.php'));
    Route::namespace($this->namespace)
        ->middleware('web')
        ->group(base_path('routes/web.php'));
    Route::namespace($this->namespace)
        ->middleware('web')
        ->group(base_path('routes/dashboard.php'));
})
