在null

Question

您好我是Laravel的新手，我正在开发一个用于发布的创建表单，用户可以使用laravel创建一个博客帖子，但是当我尝试创建帖子时，我一直都会收到错误：

Call to a member function getClientOriginalExtension() on null

这是我的表格：

@extends('master')


@section('content')

<h1>Selling your Home?</h1>




<form action="/flyers"  enctype="multpart/form-data" method="post"  >

  @inject('countries','App\Http\Utilities\Country')

你错过了一个＆＃39; i＆＃39;在您的代码上：

应为：import { BrowserRouter as Router , Route, Switch} from 'react-router-dom' ＆＃34;

而不是：

<ReactRouter.Route path="/" component={App}/>
