laravel-单选按钮/复选框将错误的值传递给数据库

Question

在创建新调查后，我正在创建调查网站，然后选择问题类型并添加问题和选项。我想检查我是否参加了调查，所有答案都将存储在数据库中。我试过了，但是问题是任何问题的答案（使用单选按钮/复选框类型），数据库中存储的值是“ on”。 文本/文本区域已正确存储。但是无法弄清楚我该如何解决。无论我选择什么，该值都将为“ on”。

这是我的answerController.php：

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Survey;
use App\Answer;
use App\Http\Requests;


class AnswerController extends Controller
{

  public function store(Request $request, Survey $survey)
  {
    // remove the token
    $arr = $request->except('_token');
    foreach ($arr as $key => $value) {
      $newAnswer = new Answer();
      if (! is_array( $value )) {
        $newValue = $value['answer'];
      } else {
        $newValue = json_encode($value['answer']);
      }
      $newAnswer->answer = $newValue;
      $newAnswer->question_id = $key;
      $newAnswer->survey_id = $survey->id;

      $newAnswer->save();

      $answerArray[] = $newAnswer;
    };
    return redirect()->action('SurveyController@view_survey_answers', [$survey->id]);
  }
}

这是答案模型：

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Answer extends Model
{
  protected $fillable = ['answer'];
  protected $table = 'answers';

  public function survey() {
    return $this->belongsTo(Survey::class);
  }

  public function question() {
    return $this->belongsTo(Question::class);
  }
}

这是用于创建问题并选择类型的代码：

@extends('master')
@section('title', 'Survey')

@section('content')
<div class="card">
    <div class="card-content">
    <span class="card-title"> {{ $survey->title }}</span>
    <p>
      {{ $survey->description }}
    </p>
    <br/>
    <a href='view/{{$survey->id}}'>Take Survey</a> | <a href="{{$survey->id}}/edit">Edit Survey</a> | <a href="/survey/answers/{{$survey->id}}">View Answers</a> <a href="#doDelete" style="float:right;" class="modal-trigger red-text">Delete Survey</a>

这是JS文件：

$(document).ready(function() {
  $('.collapsible').collapsible({
    accordion: false
  });

  $('.modal-trigger').leanModal();

  $(document).on('click', '.delete-option', function() {
    $(this).parent(".input-field").remove();
  });

  // will replace .form-g class when referenced
  var material = '<div class="input-field col input-g s12">' +
    '<input name="option_name[]" id="option_name[]" type="text">' +
    '<span style="float:right; cursor:pointer;"class="delete-option">Delete</span>' +
    '<label for="option_name">Options</label>' +
    '<span class="add-option" style="cursor:pointer;">Add Another</span>' +
    '</div>';

  // for adding new option
  $(document).on('click', '.add-option', function() {
    $(".form-g").append(material);
  });
  // allow for more options if radio or checkbox is enabled
  $(document).on('change', '#question_type', function() {
    var selected_option = $('#question_type :selected').val();
    if (selected_option === "radio" || selected_option === "checkbox") {
      $(".form-g").html(material);
    } else {
      $(".input-g").remove();
    }
  });
});

我遵循了一个教程，他说： 目前，典型的答案提交可能如下所示：

{
  4: {
    answer: "My answer"
  },
  5: {
    answer: "on"
  },
  6: {
    answer: "on"
  }
}

因此我们的函数store（）的foreach部分（$ arr as $ key => $ value）经过上述JSON对象，则键将为例如4，则值将为$值['answer']

通过这种方式，我们可以迭代并获取指向哪个问题ID的密钥，然后将答案存储在$ value ['answer']中。

^ 但是他没有解决这个问题。

因此Radio和Checkbox将是一个数组，但是代码没有参与用户从这些数组中选择的部分。 您是否知道如何更改AnswerController以告诉代码仅接受用户选择的代码？

这是负责商店部分的answerController

public function store(Request $request, Survey $survey)
  {
    // remove the token
    $arr = $request->except('_token');
    foreach ($arr as $key => $value) {
      $newAnswer = new Answer();
      if (! is_array( $value )) {
        $newValue = $value['answer'];
      } else {
        $newValue = json_encode($value['answer']);
      }
      $newAnswer->answer = $newValue;
      $newAnswer->question_id = $key;
      $newAnswer->survey_id = $survey->id;

      $newAnswer->save();

      $answerArray[] = $newAnswer;
    };
    return redirect()->action('SurveyController@view_survey_answers', [$survey->id]);
  }
}

这是答案表：

public function up()
    {
        Schema::create('answers', function (Blueprint $table) {
            $table->increments('id');
            $table->integer('question_id');
            $table->integer('survey_id');
            $table->string('answer');
            $table->timestamps();
        });
    }

有人可以帮我吗？
