I'm trying to get the error message to show when I attempt to login with the wrong username and password combination, so when I do that I don't get an error message showing. I'm not sure where I'm going wrong.

My controler

    namespace App\Http\Controllers;
    use Illuminate\Http\Request;
    use App\Http\Requests;
    use App\User;
    use Illuminate\Support\Facades\Auth;
    use Illuminate\Support\Facades\Input;

    class HomeController extends Controller
    {
        public function login(Request $request)
        {
            if(Auth::attempt(array('name' => Input::get('name'), 'password' => Input::get('password'))))
            {
                return redirect()->route('dashboard');
            }else{
                return redirect()->route('home')
                    ->with('message', 'Your username and password combination is wrong')
                    ->withInput();
            }
        }
    }

my index.blade.php

    @if ($errors->any())
        {{ implode('', $errors->all('<div>:message</div>')) }}
    @endif

    <div class="form-wrapper">
	    <div class="login-header">
		    <h1>Login</h1>
	    </div>

	    <div class="form_input">
		    {{ Form::open(array('url' => 'admin/')) }}
			    <div class="form_group">
				    {{ Form::label('name', 'Name') }}
				    {{ Form::text('name', '' , array("class" => "form-control")) }}
			    </div>

			    <div class="form_group password-section">
				    {{ Form::label('password', 'Password') }}
				    {{ Form::password('password', array("class" => "form-control")) }}
			    </div>

			    <div class="form_group submit_button">
				    {{ Form::submit('Submit', array("class" =>"btn btn-info submit", "role" => "button")) }}
			    </div>
		    {{ Form::close() }}
	    </div>
    </div>

My routes.php

    Route::group(['middleware' => 'web'], function()
    {
        Route::get('admin/', [
            'uses' => 'HomeController@index',
            'as' => 'home'
        ]);

        Route::post('/signin', [
            'uses' => 'HomeController@login',
            'as' => 'Login'
        ]);
    });
