复选框处理php laravel

Question

我有一些复选框。如何使我可以在数据库中的一个单元格中输入多个值。例如，用户选择了数学和语言。 registration.blade.php：

@extends('layouts.app')
@section('title-block')
    Регистрация
@endsection

@section('content')

    <div class="container">
        <h1 align="center">
{{--            <a href="index.html"><img src="img/logo.jpg" alt="logo" class="home"></a>--}}
            Register
        </h1>
    </div>
    <hr>
    <div class="container" align="center">
        <form name="register" method="POST" action="{{route('user.registration')}}">
            @csrf
            <input class="text-input" type="text" placeholder="Enter your surname" name="surname" required>
            <input class="text-input" type="text" placeholder="Enter your name" name="name" required><br>

            <input class="text-input" type="text" placeholder="Enter your number" name="number" required><br>

RegisterController.php：

<?php

namespace App\Http\Controllers;
use App\User;
use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
use Illuminate\Support\Facades\Auth;

class RegisterController extends Controller
{
    public function save(Request $request){
        if(Auth::check()){
            return redirect(route('user.private'));
        }

    $validateFields = $request->validate([

        'number' =>'required',
        'password' => 'required',

    ]);
        if(User::where('number',$request['number'])->exists()){
            return redirect(route('user.registration'))->withErrors([
                'number' => 'Такой пользователь уже зарегистрирован'
            ]);
        }
    $user = User::create([

        'password' => $request['password'],
        'name' => $request['name'],
        'surname'=>$request['surname'],
        'number'=>$request['number'],
        'fathers_name'=>$request['fathers_name'],
        'parents_number'=>$request['parents_number'],
        'class' => $request['btnradio'],
        'studies' => $request['btnstudies']
    ]);

    if($user){
        Auth::login($user);

        return redirect(route('user.private'));
    }
        return redirect(route('user.login'))->withErrors([
            'formError' => 'Произошла ошибка при сохранении пользователя'
        ]);
    }
}

标记的地方应该包含来自复选框的值 enter image description here

我是 laravel 和 html 的初学者。我不明白我该怎么做。我希望你能帮助我

在输入名称中添加方括号。通过这种方式，您将能够获得每个选定的输入。例如。

// view.blade.php
<form method="POST" action="/">
    @csrf
    <input type="checkbox" name="studies[]" value="a"/>
    <input type="checkbox" name="studies[]" value="b"/>
    <input type="checkbox" name="studies[]" value="c"/>
    <input type="submit"/>
</form>

// web.php
Route::post('/', function ( Request $request ) {
    dd( $request->input('studies') ); // print array of values of selected checkboxes
});
