laravel 中有些字段没有填写

Question

大家好，我遇到了一个对我来说有点“奇怪”的问题。一点背景：

我正在为考试创建一个表格，其中有一个问题，并附有 description、iframe、image 字段，图片是可选的。这些问题反过来也会有自己的领域description、iframe、image。

• 为此，我所做的是，在表单中创建一个数组question[] 到 存储该表的字段，因为它们是question[description]， question[iframe] 和 question[image]
• 对于答案应用类似的东西，二维数组 answers[][] 在一个中我保留答案的索引，在另一个中 字段，我的字段是answers[][description]、answers[][iframe] 和answers[][image]
• 当您尝试仅插入描述和视频时 问题，没有问题。问题在于回复， 并非全部保存字段。就部分而言 answers[][description] 第一个字段保存，第二个不保存 更长，第三个有，第四个没有。
• 在answers[][iframe] 中发生了同样的事情，除了第一个 字段不保存，第二个不保存，第三个不保存 第四个。

    ];

QuestionController:

<?php

namespace App\Http\Controllers;

use App\Exam;
use App\Http\Requests\QuestionRequest;
use    Illuminate\Http\Request;
use App\Question;
use function GuzzleHttp\Promise\all;

class QuestionController extends Controller

    public function create(Exam $exam)
    {
        return view('question.create', compact(['exam']));
    }

    public function store(Exam $exam, QuestionRequest $request)
    {
        $data = request()->validate([
            'question.description'  => 'required',
            'question.iframe'       => 'required',

        dd($data);

        $question = $exam->questions()->create($data['question']);
        $question->answers()->createMany($data['answers']);

        return redirect('/exams/' . $exam->id);
    }
}

我正在使用自定义Request 文件：

<?php

namespace App\Http\Requests;
use Illuminate\Foundation\Http\FormRequest;

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

    public function rules()
    {
        return [
            'question.description'  => 'required',
            'question.iframe'       => 'required',
            'answers.*.description' => 'required',
            'answers.*.iframe'      => 'required',
        ];
    }

    public function messages()
    {
        return[
            'question.description.required' => 'Debes agregar una descripcion al campo Descripcion.',
            'question.iframe.required' => 'Debes agregar el link del video al campo Video Asociado.',
            'answers.*.description.required' => 'Debes agregar una respuesta en el campo Respuesta',
            'answers.*.iframe.required' => 'Debes agregar un video en el campo Video Asociado'
        ];
    }
}

您认为问题是：answers 数组的第一个索引在每次调用中都会递增，这就是为什么您有 4 个选项的 8 个值。

为这个视图试试这个代码：

@extends('layouts.app')

@section('content')
    <div class="container">
        <div class="row justify-content-center">
            <div class="col-md-12">
                <div class="card">
                    <div class="card-header">

                        <a href="/exams/" class="btn btn-secondary btn-sm float-right" onclick="return confirm('Tus datos se perderan ¿Deseas regresar a la pagina principal?')">Regresar</a>
                    </div>
                        <div class="card-body">
                           @if($errors->any())
