Target class [] does not exist issue!

@DhPandya no the directory structure is the same i.e. app\http\controller where I have inside that folder the Controller.php and RegisterController.php which I am trying to access in my route web.php file

@josh__gikundiro every post includes a link to the formatting guide.

You may use Markdown with GitHub-flavored code blocks.

put three backticks ``` on their own line before and after the code block

@Snapey this my Controller.php

namespace App\Http\Controllers;

use Illuminate\Foundation\Auth\Access\AuthorizesRequests;
use Illuminate\Foundation\Validation\ValidatesRequests;
use Illuminate\Routing\Controller as BaseController;

class Controller extends BaseController
{
    use AuthorizesRequests, ValidatesRequests;
}

Secondary this is my RegisterController which I am trying to call through route web.php

<?php

namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use App\Models\Register;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\DB;
use App\Http\Requests;
use Illuminate\Routing\Controller as BaseController;

class RegisterController extends Controller
{


    public function store(Request $request){
        $data= $request->validate([
            'fullName'=>'string|max:255',
            'username'=> 'string|max:255',
            'address'=> 'string|max:255',
            'email'=> 'email|unique:users',
            'password'=>'string|min:8',
            'profilePicture'=> 'nullable|image|mimes:jpeg,png,jpg,gif|max:2048',
        ]);
        $register= new Register();
        $register->fullName= $request->input('fullName');
        $register->userName= $request->input('userName');
        $register->email= $request->input('email');
        $register->address= $request->input('address');
        $register->phoneNumber= $request->input('phoneNumber');
    //    profile picture
    if ($request->hasFile('profilePicture')) {
        $imagePath = $request->file('profilePicture')->store('profile_pictures', 'public');
        $data['profilePicture'] = $imagePath;
    }
    // password
    $data['password'] = Hash::make($data['password']);
    $user =User::create($data);
    return redirect()->route('login')->with('success', 'Registration successful! Please log in.');

        // $register->role= $request->input('role');
        // $register-> save();

        //     return redirect('/login')->back()->with('success','Registered successfully');

    }


    public function show(Register $register)
    {
        //
    }

    public function edit(Register $register)
    {
        //
    }


    public function update(Request $request, Register $register)
    {
        //
    }


    public function destroy(Register $register)
    {
        //
    }
    public function login(Request $request){

        $uname= $request->input('userName');
        $pwd=$request->input('password');
        $user=DB::table('registers')->where('userName',$uname)->where('password',$pwd)->get();
        if (!isset($user[0])) {
            // abort(404, 'The requested array key does not exist.');
            return redirect('/login')->with('danger', 'Invalid Credentials');
        }

        if($user[0] -> password == $pwd){
            $request->session()->put('user', $request->input('userName'));
            return redirect('/dash')->with('welcome', 'Happy day!');

        }else{
            return redirect('/login')->with('danger', 'Invalid Credentials');

        }
    }
}

and this is my web.php file

<?php

use Illuminate\Support\Facades\Route;
use App\Http\Controllers\RegisterController;


Route::view('admin','admin');
Route::view('/','index');
Route::view('signup','signup');
Route::view('login','login');
Route::post('/register','RegisterController@store');
Route::view('boot', 'boot');

?>

Thanks for the help ...

@josh__gikundiro If you are using Laravel 10, the syntax should be

Route::post('/register', [RegisterController::class, 'store']);

@Snapey let me check the authentication please...

@josh__gikundiro show more of the error
