你好，这里有个错误提示：

Symfony\Component\HttpKernel\Exception\MethodNotAllowedHttpException 没有消息

当我更新内容时。我有一个图像和一个视图要更新。

以下是我的看法。有内容被编码的地方。我在这里有提交按钮，它将触发更新。和表格@update。

admin/airlineplus/paxsafety.blade.php

    {!! Form::open(['action'=>['Admin\PaxSafetyController@update', $paxsafe->id], 'method' => 'POST','enctype'=>'multipart/form-data']) !!}
<div class="form-group">   
    <div class="table-responsive">  
        <table class="table table-bordered">  

           <tr>  
                     <th>Upload new Image and Video</th>

                     <td>  {{ Form::file('paxsafety_image[]') }} &nbsp;&nbsp; <strong>{{ $paxsafe->paxsafety_image }}&nbsp;&nbsp; </strong> </td> 

                     <td>    {{ Form::file('paxsafety_video[]') }} &nbsp;&nbsp; <strong>{{ $paxsafe->paxsafety_video }}&nbsp;&nbsp; </strong></td>


              </td>
           </tr>  
        </table><br><br>  
        {{Form::submit('submit', ['class'=>'btn btn-primary', 'name'=>'submit'])}}
    </div> 
</div>  
{!! Form::close() !!}

接下来，我的控制器。

MyCoolController.php

  $this->validate($request, [
        'paxsafety_image' => 'required',
        'paxsafety_video' => 'required'
    ]);

    if ($request->has('paxsafety_image') && $request->has('paxsafety_video'))
    {   
        //Handle File Upload

        $paxSafety = [];
        foreach ($request->file('paxsafety_image') as $key => $file)
        {
            // Get FileName
            $filenameWithExt = $file->getClientOriginalName();
            //Get just filename
            $filename = pathinfo( $filenameWithExt, PATHINFO_FILENAME);
            //Get just extension
            $extension = $file->getClientOriginalExtension();
            //Filename to Store
            $fileNameToStore = $filename.'_'.time().'.'.$extension;
            //Upload Image
            $path = $file->storeAs('public/paxsafety_folder',$fileNameToStore);
            array_push($paxSafety, $fileNameToStore);
        }


        $paxSafetyVideo = [];
        foreach ($request->file('paxsafety_video') as $key => $file)
        {
            // Get FileName
            $filenameWithExt2 = $file->getClientOriginalName();
            //Get just filename
            $filename = pathinfo( $filenameWithExt2, PATHINFO_FILENAME);
            //Get just extension
            $extension2 = $file->getClientOriginalExtension();
            //Filename to Store
            $fileNameToStore2 = $filename.'_'.time().'.'.$extension2;
            //Upload Image
            $path = $file->storeAs('public/paxsafety_folder',$fileNameToStore2);
            array_push($paxSafetyVideo, $fileNameToStore2);
        }


        $fileNameToStore = serialize($paxSafety);
        $fileNameToStore2 = serialize($paxSafetyVideo);
    }


    foreach ($paxSafety as $key => $value) {
        foreach ($paxSafetyVideo as $key => $values) {
        $paxsafe = PaxSafety::find($id);
        if($request->hasFile('paxsafety_image')){
        $paxsafe->paxsafety_image = $value;
        }
        if($request->hasFile('paxsafety_video')){
        $paxsafe->paxsafety_video = $values;
        }
        $paxsafe->save();
        }
    }
    return redirect('/admin/airlineplus/paxsafety')->with('success', 'Inflight Magazine Content Inserted');

请指导我在 Laravel 中编码的新手

【问题讨论】：

您似乎错过了控制器代码的开头？无论如何，HTTP 中的“方法不允许”异常意味着服务器不允许您用来发出请求的 HTTP 方法在您发送到的 URL 处使用。例如您的表单使用 HTTP“POST”方法提交，但也许您没有将操作方法设置为接受 POST 请求。也许它只接受 GET 什么的。
嗨，夏天，您能否发布指向处理此问题的方法的路线？
嗨 @Josh 这是我的路线 Route::resource('/admin/airlineplus/paxsafety', 'Admin\PaxSafetyController');
它适用于插入...但是当我更新它时发生错误
我已经解决了这个问题..我忘了把 csrf 或 PUT 方法放在提交按钮上方 :;) LOL 谢谢你的 HTTP

【解决方案1】：

监听你的函数的动词是 PUT，在你的代码中你使用动词 POST 解决您的问题添加 {{ Form::hidden('_method','PUT') }} 在你的表格中
