【问题描述】：

所以我做了一些改变。而且我不知道发生了什么，但几乎每个视图都会出现这种情况。

如果有人知道发生了什么，我将非常感激。有时你做出改变却不知道发生了什么。

编辑：以下是我的welcome.blade.php 中的代码：

@extends("layout")
@section("content")
            <div class="content">
            <h1>Under Construction</h1>
                        <div class="logomainpage">

                        </div>
                <div class="title m-b-md">
                    Reserveertool
                </div>

                <div class="links">
                  @if(Auth::user()->type == 1 || 2)
                    <a href="{{ url('/overview') }}">Overzicht zalen</a>
                  @endif
                    <a href="{{ url('/account') }}">Inloggen als bestaande klant</a>
                    <a href="{{ url('/reserveerzaal') }}">Zaal reserveren</a>
                    <a href="{{ url('/account') }}">Account</a>
                    <a href="{{ url('/contact') }}">Contact</a>
                </div>
            </div>
@endsection

【问题讨论】：

在welcome.blade.php中显示你的代码
我已经为你添加了它们
问题出在Auth::user()->type这一行，你的用户模型中真的有type属性吗？
如果我没记错的话，添加后它确实有效。但是，是的，我在我的用户模型中添加了 type 属性
在条件前添加dd(Auth::user())，检查是否有type。

【解决方案1】：

测试期间您没有登录

【讨论】：

更具体地说，将您的比较修改为：if(auth()->check() && in_array(auth()->user()->type, [1,2])t

【解决方案2】：

如果您确定添加了类型属性，请在此之前再添加一个条件步骤。

@extends("layout")
@section("content")
        <div class="content">
        <h1>Under Construction</h1>
            <div class="logomainpage">

            </div>
            <div class="title m-b-md">
                Reserveertool
            </div>
            @if (Auth::guest())
                    <li><a href="{{ url('/login') }}">Login</a></li>
            @else
               <div class="links">
                  @if(Auth::user()->type == 1 || 2)
                     <a href="{{ url('/overview') }}">Overzicht zalen</a>
                  @endif
                     <a href="{{ url('/account') }}">Inloggen als bestaande klant</a>
                     <a href="{{ url('/reserveerzaal') }}">Zaal reserveren</a>
                     <a href="{{ url('/account') }}">Account</a>
                     <a href="{{ url('/contact') }}">Contact</a>
               </div>
           @endif
        </div>
@endsection
