E_NOTICE 未定义索引：Laravel 中的 respondent_id答案

【问题标题】：E_NOTICE Undefined index: respondent_id in LaravelE_NOTICE 未定义索引：Laravel 中的 respondent_id
【发布时间】：2020-08-22 19:10:25
【问题描述】：

我正在尝试在我的 Laravel-5.8 应用程序中创建动态表单输入数组。

这是我的代码。

型号

class AppraisalRespondent extends Model
{
    protected $table = 'appraisal_respondents';

    protected $primaryKey = 'id';

    protected $fillable = [
              'id',
              'respondent_id',
              'department_id',
              'company_name',
              'respondent_date',
          ];

    public function employeerespondent()
    {
        return $this->belongsTo('App\Models\Hr\HrEmployee','respondent_id');
    }

    public function department()
    {
        return $this->belongsTo('App\Models\Hr\HrDepartment','department_id','id');
    }  
}

我也使用请求规则进行验证

规则请求

class StoreAppraisalRespondentRequest extends FormRequest
{
    public function rules()
    {
        return [
            'respondent_id.*' => [
                'required', 
                Rule::unique('appraisal_respondents')->where(function ($query) {
               return $query->where('appraisal_identity_id', $this->appraisal_identity_id)
                    ->where('respondent_id', $this->respondent_id)
                  ->where('employee_id', $this->employee_id);
            })               
            ],
            'department_id.*' => [
                 'required', 
            ],

            'respondent_date.*' => [
                'required', 
                'date',
                'date_format:d-m-Y',
            ],

        ];
    }  

 }

控制器

  public function store(StoreAppraisalRespondentRequest $request)
  {
      try {      
      $input = $request->all();
      $condition = $input['respondent_id'];
      foreach ($condition as $key => $condition) {
        $emprespondent = new AppraisalRespondent;
        $emprespondent->respondent_id = $input['respondent_id'][$key];
        $emprespondent->department_id = $input['department_id'][$key];
        $emprespondent->respondent_date = $input['respondent_date'][$key];         
        $emprespondent->save();
     }
     Session::flash('success', 'Appraisal Respondent(s) created successfully');
     return redirect()->route('appraisal.appraisal_respondents.index');        
        
    } catch (Exception $ex) {
            Session::flash('error', 'Action failed! Please try again');
            return redirect()->route('appraisal.appraisal_respondents.index');
    }         
}

在视图中，您会注意到当用户单击“添加”时会出现一个按钮，它会添加新行

当我提交时，我收到了这个错误：

未定义索引：responent_id

它指向控制器中的这一行：

$condition = $input['respondent_id'];

我该如何解决？

谢谢

当我将控制器代码更改为：

        foreach ($request->respondent_id as $key => $respondent_id){

    $insert_array = [
            'respondent_id'                         => $request->respondent_id[$key],
            'department_id'                         => $request->department_id[$key],                
            'respondent_date'                       => $request->respondent_date[$key],
            'company_id'                            => Auth::user()->company_id,
            'created_by'                            => Auth::user()->id,
            'created_at'                            => date("Y-m-d H:i:s"),
            'is_active'                             => 1
        ];

        AppraisalRespondent::create($insert_array );

         }

我在错误日志中得到了这个：

但该列在那里。

【问题讨论】：

@DigitalDrifter - 我该怎么做才能解决它？
拜托，你能提供$input的调试吗？我认为您选择的名称不正确。
@S.LT - 我已经更新了我的代码
好的，我看到很多语法错误，让我有时间写一个答案，希望能让你找到解决方案。

标签： javascript laravel

【解决方案1】：

我将使用您共享的循环，同时稍微更正一下语法。如果你想要一些“功能性”的东西，如果你的观点和形式是正确的，你应该尝试一下：

$inputs = $request->all(); // that give you an array, you can iterate
foreach ($inputs as $input){

    print_r($input); // that should give you:
    /*[
        'respondent_id'    => 'value_respondent_id',
        'department_id'    => 'value_department_id',                
        'respondent_date'  => 'value_respondent_date',
    ]*/
    // You can add what you want or create object or do action
}

我不想用AppraisalRespondent::create($insert_array); 做什么。我认为你需要一些知识来实现你想要的。为了做你想做的事，你需要这些资源：

检查请求如何工作：Laravel Request
检查表单验证的工作方式：Laravel Validation
检查视图如何工作：Laravel View
安装使用Laravel Debugbar

这可能是一个好的开始。
