Php Laravel-表单选择日期-仅允许用户在从数据库发送的两个日期之间进行选择

我有两张桌子——‘Trips’和‘Events’。一次旅行可以有很多活动。 我有一个表单，允许用户将事件添加到他们的旅行中。 在选择事件的开始日期和结束日期时，我只想允许用户从行程开始日期和行程结束日期中选择一个日期

例如，如果从3月1日到3月14日创建了纽约之旅，则用户只能在这些日期之间添加事件。有什么好办法吗

addEvent.blade.php `

trip.blade.php

<div class="form-group">
      <input type="text" name="destination" class="form-control" value="{{$trip->destination}}" placeholder="Destination" />
    </div>
    <h7>Trip Start Date: </h7>
    <div class="form-group">
      <input type="date" name="startdate" class="form-control" value="{{$trip->startdate}}" placeholder="Start Date" />
    </div>
    <h7>Trip End Date: </h7>
    <div class="form-group">
      <input type="date" name="enddate" class="form-control" value="{{$trip->enddate}}" placeholder="End Date" />
    </div>
    <div>

在addEvent.blade.php文件中，可以根据现有行程日期将“min”和“max”属性添加到开始日期和结束日期

{!! Form::date('start_date', \Carbon\Carbon::now(), ['class' => 'form-control', 'min' => $trip->startdate, 'max' => $trip->enddate]) !!}


{!! Form::date('end_date', null, ['class' => 'form-control', 'min' => $trip->startdate, 'max' => $trip->enddate]) !!}

在addEvent函数中，您必须为开始日期和结束日期添加验证，以便它们不会超过行程表的日期

public function addEvent(Request $request)
{

  // first take data from the trip table
  $trip = Trip::find($request->trip_id);

  // if trip not found then error
  if( !$trip ){
    return redirect('trips')->with('fail', 'Trip not found');
  }

  // add validations for start_date and end_date so that they do not exceed the dates of the trip table
  // gte is for grather than equal
  // lte is  for less than equal
  // or you can use min max

  $validator = Validator::make($request->all(),[
    'event_name' => 'required',
    'start_date' => 'required|date|min:'.$trip->startdate.'|max:'.$trip->enddate, //
    'end_date' => 'required|date|gte:start_date|max:'.$trip->enddate,
    'trip_id'=> 'required',
  ]);

  if($validator->fails()) {
    \Session::flash('warning', 'Please enter the valid details');
    return redirect('/events')->with('input', Input::all());
  }

  $events = new Events;
  $trips = Trip::all();
  $events->event_name = $request['event_name'];
  $events->start_date = $request['start_date'];
  $events->end_date = $request['end_date'];
  $events->trip_id = $request['trip_id'];
  $events->save();

return redirect('trips')->with('success', 'The new event has been added to your trip')->with('trips', $trips);
}

$start_date=Carbon:：parse（$request['start_date']）->formet（'Y-m-d'）；
$end_date=Carbon:：parse（$request['end_date']）->formet（'Y-m-d'）；
$tripCheck=Trip:where（'id'，$request['Trip\u id']）
->whereDate（'start_date'，'>='，$start_dat）
->whereDate（'end_date'），如果我在编辑功能中添加类似的内容，会有所不同吗？
public function submit(Request $request){
  $this->validate($request, [
    'name'          => 'required',
    'email'         => 'required',
