重定向回输入在 laravel 5.5 中不起作用

Question

我以前多次使用带输入的重定向返回。但是在这个项目中我无法这样做。这是我的 controller 处理表单请求的方法：

public function verifyMobileCode( Request $request)
{
        $userId = Auth::user()->id;
        if( Auth::user()->verification_code == $request['verification_code'])
        {
            User::where('id', $userId)->update(['verified'=>1]);
            return redirect('/')->with('success', 'Account verified.');
        }
        else
        {
            return redirect()->back()->withErrors('verification_code' ,'unv' )->withInput($request->all());
        }
}

这是我的表格blade:

@extends('layouts.index')

@section('content')

<div class="container" style='padding-top: 150px;'>

    <?php var_dump($errors) ; ?>
    <div class="row">
        <div class="col-md-8 col-md-offset-2">
            <div class="panel panel-default">
                <div class="panel-heading">Verify your mobile</div>

                <div class="panel-body">
                    <form class="form-horizontal" method="POST" action="{{ route('verifyMobileCode') }}">
                        {{ csrf_field() }}

                        <div class="form-group{{ $errors->has('verification_code') ? ' has-error' : '' }}">
                            <label for="verification_code" class="col-md-4 control-label">Verification code</label>

                            <div class="col-md-6">
                                <input id="verification_code" type="text" class="form-control" name="verification_code" value="{!! old('verification_code') !!}" required autofocus maxlength="6" pattern="\d{6}">

                                @if ($errors->has('verification_code'))
                                    <span class="help-block">
                                        <strong>Please enter 6 digit number sent to your mobile.</strong>
                                    </span>
                                @endif
                            </div>
                        </div>
                        <div class="form-group">
                            <div class="col-md-6 col-md-offset-4">
                                <button type="submit" class="btn btn-primary">
                                    Register
                                </button>
                            </div>
                        </div>
                    </form>
                </div>
            </div>
        </div>
    </div>
</div>

我没有发现任何错误或错误。你有看到什么吗？是否有任何调试此行为的技术？提前致谢。

Answer 1

我的方法是使用 FormRequest.

php artisan make:request VerifyCodeRequest

请求正文：

<?php

namespace App\Http\Requests;

use Illuminate\Foundation\Http\FormRequest;

class VerifyCodeRequest extends FormRequest
{

    /**
     * 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 [
            'verification_code' => 'required|in:'.$this->user()->verification_code, // since user is already logged in we check if verification_code matches using `in` rule
        ];
    }


    public function messages()
    {
        return [
            'in' => 'Your custom error message if we failed',
        ];
    }
}

现在您将 verifyMobileCode(...) 的签名更改为以下 verifyMobileCode(App\Http\Requests\VerifyCodeRequest $request)。

现在，只有当我们通过验证时，代码才会执行函数的主体 ，因此我们需要更新用户实例，我们就完成了。

public function verifyMobileCode(App\Http\Requests\VerifyCodeRequest $request) { $request->user()->verify(); return redirect('/')->with('success', 'Account verified.'); }

内部用户模型添加 verify() 函数

public function verify() { $this->update(['verified' => true]); }

如果您的上述方法不起作用，则您的 app/Http/Kernel.php 有问题。您已使用

\Illuminate\Session\Middleware\StartSession::class,

两次。你必须删除一个。应该是第一个吧。

Answer 2

将->withInput($request->all());替换为->withInput();

如果您不想使用任何一种输入

->withInput( $request->except('input_name') );

Answer 3

要在不借助 Xdebug 的情况下进行调试，快速的方法是将临时调试代码添加到 blade 文件的开头：

@php
    dd($errors->toArray(), $errors->has('verification_code'));
@endphp

这将为您提供以下输出：

array:1 [
  0 => array:1 [
    0 => "verification_code"
  ]
]
false

这表明 blade 文件中的逻辑未被评估为 true，这是显示错误样式和消息所必需的。

快速解决方法是更改要使用的控制器：

->withErrors(['verification_code' => 'unv'])

withErrors 期望作为 MessageBag 或数组，但会将字符串转换为数组，这不会导致正确的 key/value 对。

调试输出现在将显示：

array:1 [
  "verification_code" => array:1 [
    0 => "unv"
  ]
]
true

现在可以删除调试代码，错误应该如您所愿地显示。

正确的 Laravel 方法可能是对复杂的表单使用 $request->validate() 或 FormRequest。有关详细信息，请参阅 Laravel 验证文档 (https://laravel.com/docs/5.5/validation)。

Answer 4

return redirect()->back()->withInput()->withErrors('verification_code' ,'unv' );

Answer 5

您的控制器应如下所示：

public function verifyMobileCode( Request $request)
{
    $userId = Auth::user()->id;
    if( Auth::user()->verification_code == $request['verification_code'])
    {
        User::where('id', $userId)->update(['verified'=>1]);
        return redirect('/')->with('success', 'Account verified.');
    }
    else
    {
        return redirect()->back()->withErrors('message' ,'Please some errors encountered.' );
    }
}

并修改这个

<div class="form-group{{ $errors->has('verification_code') ? ' has-error' : '' }}">

为此：

<div class="form-group>
@include('errors');

同时在 resources/views 中创建名为 errors.blade.php 的文件并放入以下代码：

@if ($errors->any())
<div class="card"> //incase bootstrap 4
    <div class="error card-body alert alert-danger">
        <ul>
            @foreach ($errors->all() as $error)
                <li>{{ $error }}</li>
            @endforeach
        </ul>
    </div>
</div>
@endif

希望对你有用。但是你不需要显示旧的输入，因为代码会出错或者发生了错误。所以没必要

Answer 6

在控制器中

return redirect()->back()->withErrors('verification_code' ,'unv')->withInput();

可见

如果要检索经过验证的输入字段值，则需要对 <form></form> 和 <input> 字段使用 laravel FORM class

例子

{{ Form::open(['method' => 'post','url' => 'Your url','class'=>'form-horizontal']) }}

     {{ Form::text('verification_code','',['class'=>'form-control']) }}

{{ Form::close() }}

Answer 7

Laravel 8 上的任何人，这应该有效

return back()->withErrors('your error message is here');

如果您查看 withErrors 函数的签名，第二个参数是键，它设置为 default 除非您希望它是特定的东西。
