即使使用'file'=> true,也可以在非对象上调用成员函数getClientOriginalExtension()

Question

我得到了一个"对一个非对象的成员函数getClientOriginalExtension()的调用",尽管我已经找到了消除它的建议,包括在我的{{Form :: open}中添加'files'=> true }.

知道我走错了哪一步？

编辑 这里是我的路由

Route::resource('/contractors', 'ContractorController');
Route::controller('/contractors', 'ContractorController');
Route::post('/contractors/portfolio/{$id}', 'ContractorController@post_Portfolio');

这是我的控制器:

public function post_Portfolio($id)
    {

    $contractor = Contractor::find($id);
    $input = Input::all();
    $rules = array(
      'fileToUpload' => 'image|max:3000',
  );

  $validation = Validator::make($input, $rules);

  if ($validation->fails())
  {
    return Response::make($validation->errors->first(), 400);
  }
    $file = Input::file('filesToUpload');
    $destinationPath = 'uploads/portfolio';
    $extension = $file->getClientOriginalExtension(); 
    $filename = str_random(12).".{$extension}";
    $upload_success = Input::file('filesToUpload')->move($destinationPath, $filename);

    if( $upload_success ) { 

        //create a new portfolio and transfer the inputs to the db

        $portfolio = new Portfolio;
        $contractor = Contractor::find($id);
        $portfolio->title       = Input::get('title');
        $portfolio->description     = Input::get('projectDetails');
        $portfolio->contractor_id   = Input::get('contractor_id');
        $portfolio->save();

        $photo = new ContractorPhoto;
        $photo->portfolio_id = $portfolio->id;
        $photo->path = $destinationPath ."/". $filename;
        $photo->save();

        // redirect
        Session::flash('message', 'Successfully updated profile!');
        return Redirect::to('contractors/');

    } else {
        Session::flash('message', 'Houston we have a problem!');
        return Redirect::to('contractors/'); 
    }



}

以下是我的看法:

<div class="span8 bdb bdb-larger">
        {{ Form::open(['url' => 'contractors/portfolio/{$id}','files' => true, 'method' => 'post', $contractor->id]) }}
            <input type="hidden" name="contractor_id"  value="{{$contractor->id}}">
        <div class="row">
            <div class="span6">

                <input type="text" name="title" id="title">
                <input type="hidden" name="contractor_id"  value="{{$contractor->id}}">

        </div>

        <div class="row">
            <div class="span6">

            </div>
        </div>

        <div class="row">

            </div>
        </div>
    </div>
    {{form::close()}}

</div> 

{{HTML :: script('assets/js/scripts/portfolio.js')}}

我刚刚用Laravel实现了dropzone,我遇到了类似的问题 - 我认为问题可能是filesToUpload实际上是一个数组,所以虽然Input :: hasFile将返回true,你只能执行$ file - > move()或$ file-> getClientOriginalExtension()对该数组中的元素.

所以,如果您尝试提供索引:

$file = Input::file('filesToUpload[0]');

其余的应该工作.我知道这是一个老线程,但是当我在谷歌搜索时它突出显示,我认为这可能会帮助有同样问题的人.
