Question

对于id，我需要返回id的值。上面的图片不起作用。请有人帮帮我吗？

这是更新过的。

public function rules()
{


    return [
        'title' => 'required',
        'eventDate' => 'required|date|after:yesterday',

    ];
}

public function messages(){
    return [
        'title.required' => 'Title is required.',
        'eventDate.after' => 'Event Date is passed.',
        'eventDate.required' => 'Event Date is required.',

    ];
}
public function response(array $errors)
{
    return $this->redirector->back()
        ->withInput($this->except($this->dontFlash))
        ->withErrors($errors)
        ->with('id', $this->get('id'));
}

控制器

public function edit(Requests\EventRequest1 $request){

    $date=$_POST['eventDate'];
    $title=$_POST['title'];
    $id=$_POST['id'];
    $events=EventCal::findOrFail($id);
    $events->update($request->all());
    DB::table('event_cals')
                ->where('id',$id)
                ->update(['title' => $title,'eventDate' => $date]);
    return redirect('/dcalendar');

}

视图

@foreach($events as $evnts)
    {!! Form::open(array('url'=>'ecalendar','method'=>'POST')) !!}
    <table >
        <th>Title</th>
        <th>Event Date</th>
        <tr>
            <td><input type="text" name="title" value={!!$evnts->title  !!}> &nbsp;&nbsp;&nbsp;&nbsp; </td>

            <td><input type="date" name="eventDate" value={!!$evnts->eventDate  !!}> &nbsp;&nbsp;&nbsp;&nbsp;</td>


            <td><input type="text" name="id" value={!!$evnts->id  !!}> </td><br>
            <td> <a href="dcalendar/{!!$evnts->eventDate  !!}/{!!$evnts->title  !!}"><input type="button" name="delete" value="Delete"/> </a></td><br>
            <td> <input type="submit" name="edit" value="edit"/> </td><br>


        @if($errors->has('title'))

                <td><ul class="alert alert-danger" style="width: 250px;height: 40px"> {{$errors->first('title')}} </ul></td>


        @endif
        @if($errors->has('eventDate'))

                <td><ul class="alert alert-danger" style="width: 250px;height: 40px"> {{$id}}</ul></td>



        @endif
        </tr>
        <hr>
    </table>
    {!! Form::close() !!}
@endforeach

表单值将从db检索值。当我更新值时，应该会出现从请求类中出现的错误消息。对于{{$ id}}，我需要id的值。

在Class的顶部，只需输入，您的请求就可以。

Use Request;

如果您有任何错误，请告知我们，还提供完整的FormRequest文件代码

如何使用请求类在laravel 5中返回一个值？
