如何在 Laravel 8 上将选定的复选框 ID 存储到我的数据库中

Question

我创建了一个动态调查生成器应用程序，调查创建者可以在其中选择要提出的问题类型（单选、复选框、文本和文本区域）。用户响应的存储正确保存在我的复选框中除外。如果用户选择了 3 个或 2 个复选框，那么它只会将 1 个保存到数据库中。请帮助我是 laravel 的新手。谢谢

This is my store function in controller

  public function surveystore(Questionnaire $questionnaire, Request $request){

  
            $data = request()->validate([
            'responses.*.answer_id' => 'required_if:responses.*.questiontype,radio,|required_if:responses.*.questiontype,checkbox',
            'responses.*.answer_text' => 'required_if:responses.*.questiontype,text,|required_if:responses.*.questiontype,textarea',
            'responses.*.question_id' => 'required',
            'survey.name' => 'required',    //present ang ilagay kung need na confidential
            'survey.email' => 'required',   //present ang ilagay kung need na confidential
                ]);

          
             $survey= $questionnaire->surveys()->create($data['survey']);
             $survey->responses()->createMany($data['responses']);

             return redirect()->back()->with('message', 'Thank You! :)');

             
        }

This is my route

Route::get('dsb/creator/surveys/{questionnaire}-{slug}', [dsbCreatorController::class, 'surveyshow'])->name('dsb/creator/surveyshow/{questionnaire}-{slug}');
Route::post('dsb/creator/surveys/{questionnaire}-{slug}', [dsbCreatorController::class, 'surveystore'])->name('dsb/creator/surveystore/{questionnaire}-{slug}');

This is my surveyshow.blade.php (the survey form that the users will take to answer)

<div class="container">
            
            @if(session()->has('message'))
                    <div class="alert alert-success">
                        {{ session()->get('message') }}
                    </div>
                @endif

                    </div>

This is my SurveyResponse Model's function

use HasFactory;

public function survey()

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

Answer 1

array:4 [▼ 
0 => array:2 [▼ "answer_id" => "89" "question_id" => "103" ] 
1 => array:2 [▼ "answer_id" => array:2 [▼ 0 => "90" 1 => "91" ] "question_id" => "104" ]
2 => array:2 [▼ "answer_text" => "answer to text" "question_id" => "105" ] 
3 => array:2 [▼ "answer_text" => "answer to textarea" "question_id" => "106" ] ]

在第二个索引answer_id中是一个数组。 createMany() 方法无法处理此 properly.I 认为导致 problem.You 可以使用 foreach 循环更改您的代码以存储 $data['responses'] 并检查值是否为 array.If 然后再次迭代到 save.For 示例；

foreach ($data['responses'] as $response) {
    if (isset($response['answer_id']) && is_array($response['answer_id'])) {
        foreach ($response['answer_id'] as $value) {
            $survey->responses()->createOne(
                [
                    "answer_id" => $value,
                    "question_id" => $response['question_id']
                ]
            );
        }
    } else {
        $survey->responses()->createOne($response);
    }
}
