Question

我遇到了一个问题，我错过了路线的行为。如果我尝试随机URL，则不会抛出任何异常，我会得到一个

未定义的变量：错误

而不是我创建的404页面。问题是，如果我尝试从有效的现有路由访问数据库中不存在的对象，则抛出404错误并且页面呈现它应该的样式。

我的错误页面的布局包括一个顶部栏，在该栏中有一个我在主布局中包含的模态表单（未定义的错误显然来自该模态）：

mastererror.blade.php：

<!DOCTYPE html>
 <html>
 <head>
    <title>@yield('title')</title>
    <!-- Load CSS -->
    @include('assets.css')
    <!--------------> 
    <!-- Load jQuery -->
    <script src="{{ URL::asset('js/jquery-2.1.4.min.js')}}"></script>
    <!----------------->

 </head>
 <body>

 <!-- Load Navbar -->
 @include('elements.html.navbartop')
 <!----------------->
 <div class="pusher">

    <div id="content" class="ui main container" style="margin: 70px 0px 50px  0px">
        <!-- Load Content -->
        @yield('content')
        <!------------------>
    </div>
 </div>
 <!-- Load Footer -->
 @include('elements.html.footer')
 <!----------------->
 <!-- Load JavaScript -->
 @include('assets.js')
 <!--------------------->

 <!-- Load login Modal -->
 @include('elements.html.partials.login-modal')
 <!---------------------->

 </body>
 </html>

404.blade.php：

@extends('layout.mastererror')

@section('title', 'Not Found.')

@section('content')

<div style="margin-top: 30px">
    <img class="ui medium image centered" src="{{asset('images/notfound.png')}}">
    <h1 class="ui header centered">404 Not Found.</h1>
    @if($exception->getMessage() !== '')
        <h2 class="ui header centered">{{ $exception->getMessage() }}.</h2>
    @else
        <h2 class="ui header centered">The resource is missing.</h2>
    @endif
    <h3 class="ui header centered"><a href="{{ route('index') }}">Home</a>   </h3>
</div>

@endsection

    </div>
</div>

Answer 1

抛出错误时不会生成魔法$errors变量（在此处详细讨论：https://github.com/laravel/framework/issues/11457）。

您需要对引用isset($errors)

的所有模板$errors进行操作

<div class="field {!! isset($errors) ? ( $errors->has('username') ? 'error' : '' ) : '' !!}">

Answer 2

现在我添加了这条路线来捕捉任何无效路线：

Route::any('{catchall}', function($page){
        abort(404,"the page '$page' doesnt exist");
    })->where('catchall', '(.*)');

Laravel 5缺少路线不会抛出异常
