jquery - Laravel - 如何处理未定义的偏移量：1

Question

我有一个 Laravel-5.8 项目。我正在使用动态输入字段，如下所示：

StoreAppraisalGoalRequest

class StoreAppraisalGoalRequest extends FormRequest
{
public function authorize()
{
    return \Gate::allows('appraisal_goal_create');
}
public function rules()
{
    return [
        'goal_title'                => 'required|min:5|max:100|unique:appraisal_goals,goal_title,goal_type_id,appraisal_identity_id,employee_id',   
        'goal_type_id'              => 'required',
        'weighted_score'            => 'required|numeric|min:0|max:500',

        'start_date'                => 'required',
        'end_date'                  => 'required|after_or_equal:start_date',
        'appraisal_goal_id'         => 'required',
        'kpi_description'           => 'required|max:300',
        'activity'                  => 'required|max:300',
    ];
  }
}

</script>

当我点击保存时，我收到了这个错误

未定义的偏移量：1

我还发现这个突出显示： :\xampp\htdocs\peopleedge\vendor\laravel\framework\src\Illuminate\Validation\Concerns\ValidatesAttributes.php return $last; }

return $attribute;
}
protected function getExtraConditions(array $segments)
{
  $extra = [];

$count = count($segments);

for ($i = 0; $i < $count; $i += 2) {
    $extra[$segments[$i]] = $segments[$i + 1];
}

  return $extra;
}

我该如何解决？

谢谢
