保存数组，从刀片到控制器 Laravel

Question

我想将所有这些可能是数组的数据保存到我的答案表中。我尝试了很多方法，但似乎找不到正确的解决方案..有人可以帮我谢谢。我不知道如何将 answer(create.blade.php) 中的数据存储到 AnswerController 中的 store 函数上的数据库中，因为我不明白如何使用 $key=> $value 的东西。我还在学习，因为我真的把我的心放在了 Laravel 上。 Laravel 的专业人士可以帮助我或指导我吗？太感谢你了。。

问题模型

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Question extends Model
{
    public function feedback()
    {
        return $this->belongsTo('App\Feedback','feedback_id');
    }

    public function answers()
    {
        return $this->hasMany('App\Answer');
    }

}

答案模型

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Answer extends Model
{
    protected $fillable = ['question_id', 'feedback_type', 'answer'];

    public function question()
    {
        return $this->belongsTo('App\Answer','question_id');
    }

   /* public function user()
    {
        return $this->belongsTo('App\Answer','user_id');
    } */
}

答案（create.blade.php）

应答控制器

<?php

namespace App\Http\Controllers;

namespace App\Http\Controllers;
use App\Feedback;
use App\Answer;
use App\Question;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Redirect;

class AnswerController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function index()
    {
        $questions = Question::all();
        return view('Answer.index',compact('questions'));
    }

    /**
     * Show the form for creating a new resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function create()
    {
        $questions = Question::all();
        return view('Answer.create',compact('questions'));
    }

    /**
     * Store a newly created resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return \Illuminate\Http\Response
     */
    public function store(Request $request)
    {
       foreach ($request->question as $key => $value){
           $answer = new Answer();
           $answer -> question_id = $value;
           $answer -> answer = $request->input('answer');
           $answer -> save();
       }

        return Redirect::back();
    }

路线

<?php

Route::resource('feedbacks','FeedbackController');
Route::resource('questions','QuestionController');
Route::resource('answers','AnswerController');
Auth::routes();
Route::get('/home', 'HomeController@index')->name('home');

Answer 1

当您从请求中获得答案时，主要问题出在您的控制器中：

$answer -> answer = $request->input('answer');

请求包含question_id 作为键的答案数组。因此，您可以通过以下方式获得相关答案：

$answer -> answer = $request->input('answer.'.$value);

**关键是 Laravel 使用点表示法来获取数组帖子。
