Getting "Class 'app\Http\Controllers\Controller' not found" in Laravel 5.1
Let's go through this step by step.
1. Check autoload directive on composer.json
Open composer.json
file on your project root directory. Locate the the autoload
section. It should be looking like this:
{
...
"autoload": {
"classmap": [
"database"
],
"psr-4": {
"App\\": "app/"
}
},
}
Make sure you have this configuration under the psr-4
option:
"App\\": "app/"
This configuration tells the composer that we want to autoload all classes inside the app
directory using psr-4 convention and places it under the App
namespace.
2. Update your controller
First, your controller file name should be in CamelCase style. So we have to renamed it to TestController.php
. Make sure that it's saved under app/Http/Controllers
directory.
Now open your TestController.php
file, we have to capitalize the namespace and class name like so:
<?php
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
class TestController extends Controller {
public function getAbout()
{
return view('Learning.about') ;
}
public function getHome()
{
return view('Learning.index');
}
}
Note that we also turn this line:
class testController extends \app\Http\Controllers\Controller
Into:
class TestController extends Controller
Since we already import the base Controller
class, we don't have to specify the fully qualified name. We imported the Controller
class using the use
keyword:
use App\Http\Controllers\Controller;
Save your TestController.php
file.
3. Update your routes file
Now we have to update our app\Http\routes.php
file. We just need to capitalize the controller name:
<?php
Route::get('test', ['uses' => 'TestController@getHome', 'as' => 'test']);
Route::get('about', ['uses' => 'TestController@getAbout', 'as' => 'about']);
4 Update your autoloader
Now the last thing to do. Open your terminal / command prompt. Go to your project directory and run the following command:
composer dump-autoload
This command will update the autoloader file (Read more here).
Now if you open up your browser and hit /test
route, you should see the content from resources/views/Learning/index.blade
.

I'm quite new to Laravel and when I am going through a tutorial when I encountered this error. This is my code in 'testController.php'.
<?php namespace app\Http\Controllers; use app\Http\Controllers\Controller; class testController extends \app\Http\Controllers\Controller { public function getAbout() { return view('Learning.about') ; } public function getHome() { return view('Learning.index'); } }
And this is my 'routes.php'.
<?php Route::get('test', [ 'as' => 'test', 'uses' => 'testController@getHome', ]); Route::get('about', [ 'as' => 'about', 'uses' => 'testController@getAbout', ]);
I am getting this error:
Class 'app\Http\Controllers\Controller' not found
How can I fix this error?

Alexey Mezenin over 7 yearsYou controller is in
app\Http\Controllers
, right? -
TheShark over 7 yearsYes it is in the Controllers, same with 'testController'.
-
Alexey Mezenin over 7 yearsDid you remove
use app\Http\Controllers\Controller;
line? -
TheShark over 7 yearsActually the Controller.php lies as 'App\Http\Controllers\Auth\Controller.php'. I don't think it makes any difference to the name space, do it ?
-
TheShark over 7 yearsYes I did but didn't do any difference. By the way, I just noticed that my Controller.php has the path 'App\Http\Controllers\Auth\Controller.php'. Does it affect here to the code ?

Saumya Rastogi over 7 yearsI think the casing of letters differ according to different OS, like in mac it reacts to be right else in Ubuntu it reacts to be wrong, etc for other OS too

Alexey Mezenin over 7 yearsIf you still getting
app\..
message, then you didn't remove the line or didn't change namespace orextends
part. The code above is from standard Laravel controller. Double check everything.
