使用RESTful路由时Laravel 5.1.4验证无法填充旧数据 [英] Laravel 5.1.4 validation fail not populating old data when using RESTful routes

问题描述

我正在尝试建立一个后端管理区域，以将用户添加到我的应用程序中(我不希望用户注册，我希望他们由管理员设置).

I'm trying to build a back end admin area to add users to my application (I don't want users to register I want them to be set up by an admin).

我已经创建了必要的控制器和请求.

I've created the necessary controller and request.

如果数据可接受，它将通过POST请求提交到domain.tld/admin/users，并通过UserController@store存储.

If the data is acceptable it submits via a POST request to domain.tld/admin/users and is stored via UserController@store.

不满足验证条件时，会将用户发送回表单(domain.tld/admin/users/create)，并显示错误消息，但不会使用先前填写的数据填充字段

When the validation criteria isn't met, the user is sent back to the form (domain.tld/admin/users/create) and error messages are shown, but the fields aren't populated with the previously filled out data.

我正在使用Route::resource('admin/users')进行RESTful路由创建和干净的路由文件，我发现当对，FormRequest不会填充旧数据.

I'm using Route::resource('admin/users') for RESTful route creation and a clean routes file, I've found that when the HTTP POST request is made to the parent route (domain.tld/admin/users) as generated by Route::resource(), the FormRequest doesn't populate the old data.

但是，当对表单所在的创建路径(domain.tld/admin/users/create)发出HTTP POST请求时，验证失败将正确地填充旧数据.

But when the HTTP POST request is made to the create route where the form is situated (domain.tld/admin/users/create), the validation fail populates the old data correctly.

在仍然使用Route::resource('admin/users')而无需在我的视图中使用{{ old('') }}帮助器的情况下，有什么方法可以使这项工作正常进行?

Is there any way to make this work as it should whilst still using Route::resource('admin/users') without having to use the {{ old('') }} helper in my views?

UsersController (非常基本)

<?php

namespace App\Http\Controllers\Admin;

use Illuminate\Http\Request;

use App\Http\Requests;
use App\Http\Controllers\Controller;
use App\User;
use App\Http\Requests\Admin\UserCreateRequest;

class UsersController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return Response
     */
    public function index()
    {
        $users = User::all();
        return view('admin.users.index', compact('users'));
    }

    /**
     * Show the form for creating a new resource.
     *
     * @return Response
     */
    public function create()
    {
        $users = User::all();
        return view('admin.users.create');
    }

    /**
     * Store a newly created resource in storage.
     *
     * @param  Request  $request
     * @return Response
     */
    public function store(UserCreateRequest $request)
    {
        //
    }

    /**
     * Display the specified resource.
     *
     * @param  int  $id
     * @return Response
     */
    public function show($id)
    {
        //
    }

    /**
     * Show the form for editing the specified resource.
     *
     * @param  int  $id
     * @return Response
     */
    public function edit($id)
    {
        //
    }

    /**
     * Update the specified resource in storage.
     *
     * @param  Request  $request
     * @param  int  $id
     * @return Response
     */
    public function update(Request $request, $id)
    {
        //
    }

    /**
     * Remove the specified resource from storage.
     *
     * @param  int  $id
     * @return Response
     */
    public function destroy($id)
    {
        //
    }
}

UserCreateRequest

<?php

namespace App\Http\Requests\Admin;

use App\Http\Requests\Request;

class UserCreateRequest extends Request
{
    /**
     * Determine if the user is authorized to make this request.
     *
     * @return bool
     */
    public function authorize()
    {
        return true;
    }

    /**
     * Get the validation rules that apply to the request.
     *
     * @return array
     */
    public function rules()
    {
        return [
            'first_name' => 'required|max:255',
            'last_name' => 'required|max:255',
            'email' => 'required|confirmed|email|max:255|unique:users',
            'password' => 'required|confirmed|min:6',
        ];
    }
}

create.blade.php

@extends('admin._layouts.master')

@section('title', 'Create a user')

@section('content')

    <form method="post" action="{{ action('Admin\UsersController@store') }}">

        @foreach ($errors->all() as $error)
            <p class="alert alert-danger">{{ $error }}</p>
        @endforeach

        @if (session('status'))
            <div class="alert alert-success">
                {{ session('status') }}
            </div>
        @endif

        {!! csrf_field() !!}

        <div class="form-group">
            <label for="first_name">First Name</label>
            <input class="form-control" id="first_name" placeholder="First Name" type="text" name="first_name">
        </div>

        <div class="form-group">
            <label for="last_name">Last Name</label>
            <input class="form-control" id="last_name" placeholder="Last Name" type="text" name="last_name">
        </div>

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

        <div class="form-group">

            <input class="form-control" id="email_confirmation" placeholder="Email" type="email" name="email_confirmation">
        </div>

        <div class="form-group">
            <label for="password">Password</label>
            <input class="form-control" id="password" placeholder="Password" type="password" name="password">
        </div>

        <div class="form-group">
            <label for="password_confirmation">Confirm Password</label>
            <input class="form-control" id="password_confirmation" placeholder="Password" type="password" name="password_confirmation">
        </div>

        <button class="btn btn-default" type="submit">Submit</button>
    </form>

推荐答案

您要使用类Input获取Laravel中的旧帖子数据.

you want to use the class Input to get old post data in Laravel.

<input type="text" class="form-control" value="{{Input::old('name')}}" name="name" placeholder="Enter name" required="required" />
