[php] laravel 5 : Class 'input' not found

In my routes.php file I have :

Route::get('/', function () {

    return view('login');
});

Route::get('/index', function(){
    return view('index');
});

Route::get('/register', function(){
    return view('register');
});
Route::post('/register',function(){

    $user = new \App\User;
    $user->username = input::get('username');
    $user->email  = input::get('email');
    $user->password = Hash::make(input::get('username'));
    $user->designation = input::get('designation');
    $user->save();

});

I have a form for users registration. I am also taking the form inputs value in the routes.php.

But the error comes up when I register a user . Error:

FatalErrorException in routes.php line 61:
Class 'input' not found

Add this in config/app.php under aliases:-

'Input' => Illuminate\Support\Facades\Input::class,

'Input' => Illuminate\Support\Facades\Input::class, add it to App.php.

You can add a facade in your folder\config\app.php

'Input' => Illuminate\Support\Facades\Input::class,

if You use Laravel version 5.2 Review this: https://laravel.com/docs/5.2/requests#accessing-the-request

use Illuminate\Http\Request;//Access able for All requests
...

class myController extends Controller{
   public function myfunction(Request $request){
     $name = $request->input('username');
   }
 }

For laravel < 5.2:

Open config/app.php and add the Input class to aliases:

'aliases' => [
// ...
  'Input' => Illuminate\Support\Facades\Input::class,
// ...
],

For laravel >= 5.2

Change Input:: to Request::

Declaration in config/app.php under aliases:-

'Input' => Illuminate\Support\Facades\Input::class,

Or You can import Input facade directly as required,

use Illuminate\Support\Facades\Input;

or

use Illuminate\Support\Facades\Input as input;

Miscall of Class it should be Input not input

In Laravel 5.2 Input:: is replaced with Request::

use

Request::

Add to the top of Controller or any other Class

use Illuminate\Http\Request;

In larvel => 6 Version:

Input no longer exists In larvel 6,7,8 Version. Use Request instead of Input.

Based on the Laravel docs, since version 6.x Input has been removed.

The Input Facade

Likelihood Of Impact: Medium

The Input facade, which was primarily a duplicate of the Request facade, has been removed. If you are using the Input::get method, you should now call the Request::input method. All other calls to the Input facade may simply be updated to use the Request facade.

use Illuminate\Support\Facades\Request;
..
..
..
 public function functionName(Request $request)
    {
        $searchInput = $request->q;
}

It's changed in laravel 6. See for more info here

Don't do anything in app.php and anywhere else, just replace

input::get() with Request::input()

and

on top where you declare Input,Validator,Hash etc., remove Input and add Request

use something like :

Config,DB,File,Hash,Input,Redirect,Session,View,Validator,Request;

   #config/app.php
   'aliases' => [
        ...
        'Input' => Illuminate\Support\Facades\Input::class,
        ...
    ],

   #Use Controller file
   use Illuminate\Support\Facades\Input;
   ==OR==
   use Input;

Read full example: https://devnote.in/laravel-class-input-not-found

This clean code snippet works fine for me:

use Illuminate\Http\Request;
Route::post('/register',function(Request $request){

   $user = new \App\User;
   $user->username = $request->input('username');
   $user->email  = $request->input('email');
   $user->password = Hash::make($request->input('username'));
   $user->designation = $request->input('designation');
   $user->save();
});

In first your problem is about the spelling of the input class, should be Input instead of input. And you have to import the class with the good namespace.

use Illuminate\Support\Facades\Input;

If you want it called 'input' not 'Input', add this :

use Illuminate\Support\Facades\Input as input;

Second, It's a dirty way to store into the database via route.php, and you're not processing data validation. If a sent parameter isn't what you expected, maybe an SQL error will appear, its caused by the data type. You should use controller to interact with information and store via the model in the controller method.

The route.php file handles routing. It is designed to make the link between the controller and the asked route.
