请我不知道还能做什么。我创建了一个资源控制器，一切正常，create.blade 可以访问并且工作正常，事实上，正在保存到数据库中。甚至索引页面在它只是普通 HTML 之前也可以工作，但我立即插入 PHP 详细信息，它开始加载服务器错误 500。请参见下文：
我的 index.blade
<div class="col-md-6" style="float:right">
<a href="{{ route('paymentdetails.create') }}" class="btn btn-primary btn-rounded float-right">

@lang('Add Paymentdetails')
</a>
</div>
<div class="table-responsive" id="users-table-wrapper">
<table class="table table-borderless table-striped">

<th class="min-width-150">@lang('Amountpaid')</th>

<th class="min-width-80">@lang('Created_at')</th>
