Laravel 5.2验证错误未出现在刀片中 [英] Laravel 5.2 Validation Error not appearing in blade

问题描述

我想在用户输入错误的同时在视图"页面中显示验证错误.可以肯定的是，当用户输入错误时，它不会在数据库中保存任何内容.但是用户视图页面中没有错误消息.如果有人发现错误，请帮助我.

I want to show validation Error in View page while user giving wrong input. It's Ok that it's not saving anything in database while a user giving wrong input. But there is no error message in user view page. If anyone find the error, please help me out.

这是控制器:

public function saveUser(Request $request){
        $this->validate($request,[
            'name' => 'required|max:120',
            'email' => 'required|email|unique:users',
            'phone' => 'required|min:11|numeric',
            'course_id'=>'required'
            ]);

        $user = new User();
        $user->name=  $request->Input(['name']);
        $user->email=  $request->Input(['email']);
        $user->phone=  $request->Input(['phone']);
        $user->date = date('Y-m-d');
        $user->completed_status = '0';
        $user->course_id=$request->Input(['course_id']);
        $user->save();
       return redirect('success');         
    }

这是路线:

Route::group(['middleware' => 'web'], function () {

    Route::get('/', function () {
        return view('index');
    })->name('main');

      Route::post('/saveUser',[
        'uses' => 'AppController@saveUser',
        'as'=>'saveUser',
        ]);
    });

这是刀片视图页面:

@extends('layouts.master')
@section('title')
Create User
@endsection
@section('content')
@include('partials.message-block')
        <div class="container" >

            <h3> Student Register </h3>

        {!! Form::open(array('route' => 'saveUser','class'=>'form-horizontal','method'=>'POST'))  !!}
      {!! Form::token(); !!}
      {!!   csrf_field() ; !!} 

        <div class="form-group">
          <label>Name</label>
          <input type="text" name="name" class="form-control" required placeholder="Name">
        </div>

        <div class="form-group">
          <label>Email</label>
          <input type="email" name="email" class="form-control" required placeholder="email">
        </div>

        <div class="form-group">
          <label>Phone Number</label>          
          <input type="text" name="phone" class="form-control" required placeholder="phone">
        </div>

        <div class="form-group">
            <label for="">Class</label>
            <select class="form-control input-sm" name="course_id" >
            @foreach($input as $row)
            <option value="{{$row->id}}">{{$row->name}}</option>
            @endforeach
            </select>
        </div>  

        <button type="submit" class="btn btn-default">Submit</button>
    {!! Form::close() !!}
        </div>

@endsection

这是错误消息块:

@if(count($errors) > 0)
    <div class="row">
        <div class="col-md-4 col-md-offset-4 error">
            <ul>
                @foreach($errors->all() as $error)
                    <li>{{$error}}</li>
                @endforeach
            </ul>
        </div>
    </div>
@endif
@if(Session::has('message'))
<div class="row">
    <div class="col-md-4 col-md--offset-4 success">
        {{Session::get('message')}}
    </div>
</div>

@endif

推荐答案

如果您使用的是5.2.27或更高版本，请尝试删除web中间件.现在，Laravel会自动将web中间件应用于routes.php内部的所有路由，如果您尝试手动添加它，则会出错.

Try to remove web middleware if you're using 5.2.27 or higher. The thing is now Laravel automatically applies web middleware to all routes inside routes.php and if you're trying to add it manually you can get errors.

app/Providers/RouteServiceProvider.php现在将Web中间件添加到routes.php内的所有路由:

app/Providers/RouteServiceProvider.php of the 5.2.27 version now adds web middleware to all routes inside routes.php:

protected function mapWebRoutes(Router $router)
{
    $router->group([
        'namespace' => $this->namespace, 'middleware' => 'web',
    ], function ($router) {
        require app_path('Http/routes.php');
    });
}
