Route:

Route::get('/home', 'HomeController@index');
Route::resource('/profile', 'ProfileController@show');

HomeController.php

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\User;
class HomeController extends Controller
{
    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function __construct()
    {
        $this->middleware('auth');
    }

    /**
     * Show the application dashboard.
     *
     * @return \Illuminate\Http\Response
     */
    public function index()
    {

        return view('home');
    }

}

ProfileController.php

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\User;
class ProfileController extends Controller
{

    public function index()
    {

    }


    public function create()
    {
        //
    }


    public function store(Request $request)
    {
        //
    }


    public function show($id)
    {
        $users = User::find($id);

        return view('profile.index',compact('users'));


    }


    public function edit($id)
    {
        //
    }


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


    public function destroy($id)
    {
        //
    }
}

and this is index.blade.php of Profile folder. This is where should be the output.

@section('content')

How to solve this problem?

Answer 1

When using

Route::resource...

you can't specify a function. Just use:

Route::resource('/profile', 'ProfileController');

EDIT:

Route::resource creates 6 routes for you. See my image below.

As your route needs a parameter (the $id) you need to pass it a parameter. Maybe it's easier to use named routes also. So instead of

<a href="{{ URL::to('profile') }}">Profile</a>

you would write

<a href="{{ route('profile.show', Auth::user()->id) }}">Profile</a>

You can see all available routes with the command

php artisan route:list

The output should look like this:
