Question

当我输入$ request-＆gt;文件（'photo'）或$ request-＆gt;输入（'photo'）时，我得到null，即使我在FORM :: open中有files =＆gt; true。我在login.blade.php中使用注册表单，它看起来像：

{{FORM::open(['id'=>'registerForm','url'=>'register','files'=>true,'novalidate'])}}
  <h1>Krijo llogari</h1>
  <div>
      {{FORM::text('first_name',null,['class'=>'form-control','required','placeholder'=>'Emri'])}}
  </div>
  <div>
      {{FORM::text('last_name',null,['class'=>'form-control','required','placeholder'=>'Mbiemri'])}}
  </div>
  <div>
      {{FORM::password('password',['class'=>'form-control','placeholder'=>'Fjalëkalimi','required'])}}
  </div>
  <div>
      {{FORM::password('password_confirmation',['class'=>'form-control','placeholder'=>'Konfirmo fjalëkalimin','required'])}}
  </div>
  <div>
      {{FORM::select('acedemical_title_id',array_merge(['0'=>'Zgjedhe titullin akademik'],$academicalTitles),null,['class'=>'form-control','required','style'=>'border-radius:2px'])}}
  </div>
  <br>
  <div>
      {{FORM::select('cpa_id',array_merge(['0'=>'Zgjedhe profesor/asistent'],$cpas),null,['class'=>'form-control','required','style'=>'border-radius:2px'])}}
  </div>
  <br>
  <div>
      {{FORM::text('personal_number',null,['class'=>'form-control','required','placeholder'=>'Numri personal','maxlength'=>'10'])}}
  </div>
  <div>
      {{FORM::email('email',null,['class'=>'form-control','required','placeholder'=>'E-mail'])}}
  </div>
    <div>
        <div class="input-group image-preview">
            <span class="input-group-btn">
                <!-- image-preview-clear button -->
                <button type="button" class="btn btn-default image-preview-clear" style="display:none;">
                    <span class="glyphicon glyphicon-remove"></span> Pastro
                </button>
                    <!-- image-preview-input -->
                <div class="btn btn-default image-preview-input">
                    <span class="glyphicon glyphicon-folder-open"></span>
                    <span class="image-preview-input-title">Zgjedh foton</span>
                    {!! FORM::file('photo') !!}
                </div>
            </span>
        </div>
    </div>
  <br>
  <div>

      {{FORM::submit('Regjistrohu',['class'=>'btn btn-success pull-right'])}}
  </div>

  <div class="clearfix"></div>

  <div class="separator">
    <p class="change_link">Keni llogari?
      <a href="#signin" class="to_register"> Kyçu </a>
    </p>

    <div class="clearfix"></div>
    <br />

    <div>
        <h1><i class="fa fa-xalfa"></i> XALFA - Për krijimin e orarit!</h1>
        <p>©2016 All Rights Reserved. XALFA Inc. Privacy and Terms</p>
    </div>
  </div>
{{FORM::close()}}

虽然我的控制器看起来像这样：

    public function store(Request $request)
{
    try{
        //dd($request->file('photo'));
        $destination_folder = 'Uploads/';

        $validator = Validator::make($request->all(),[
            'first_name' => 'bail|required|alpha|max:190',
            'last_name' => 'bail|required|alpha|max:190',
            'email' => 'bail|required|email|max:190',
            'password'=>'bail|required|confirmed|max:190',
            'personal_number'=>'bail|required|numeric',
            'cpa_id' => 'bail|required|numeric',
            'acedemical_title_id' => 'bail|required|numeric',
            'photo' => 'bail|require|image|mime:jpeg,png|max:1000000',
        ]);

        if($validator->fails()){
            return response()->json([
                'fails'=>true,
                'title'=>'Gabim gjatë validimit!',
                'msg'=>$validator->getMessageBag()->toArray()
            ],400);
        }

        $data = $request->all();
        if($request->hasFile('photo')){
            dd('asdasgasdasd');
            $file = $request->file('photo');

            $filename = $file->getClientOriginalName().'-'.str_random(8);

            $file->move($destination_folder,$filename);

            $data['photo']=$destination_folder.$filename;
        }else{
            dd('nuk hini hiq');
        }


        if($user = Sentinel::register($data)){
            if($activation = Activation::create($user)){
                if($role = Sentinel::findRoleBySlug('user')){
                    $role->users()->attach($user);

                    $this->sendMail($user, $activation->code);

                    return response()->json([
                        'success'=>true,
                        'title'=>'Aktivizimi',
                        'msg'=>'Për të aktivizuar llogarinë tuaj kontrollo postën tuaj elektronike!'
                    ],200);
                }else{
                    return response()->json([
                        'fails'=>true,
                        'title'=>'Gabim internal',
                        'msg'=>'Ju lutemi kontaktoni mbështetësit e faqes!'
                    ],400);
                }
            }
        }else{
            return response()->json([
                'fails'=>true,
                'title'=>'Gabim gjatë regjistrimit',
                'msg'=>'Ju lutemi shikoni për parregullsi në të dhëna!'
            ],400);
        }
    }catch(QueryException $e){
        return response()->json([
            'fails'=>true,
            'title'=>'Gabim në server!',
            'msg'=>'Ju lutem kontaktoni mirëmbajtësit e faqes.',
        ],500);
    }
    catch(ErrorException $e){
        return response()->json([
            'fails'=>true,
            'title'=>'Gabim në server!',
            'msg'=>'Ju lutem kontaktoni mirëmbajtësit e faqes.'
        ],500);
    }

}

我的ajax javascript代码如下：

$('#registerForm').submit(function(e){
    e.preventDefault();

    $.ajaxSetup({
        headers:{
            'X-CSRF-TOKEN': $('meta[name=csrf-token]').attr('content')
        }
    });

    var form = $(this), formData=form.serialize(), url=form.attr('action');

    $.ajax({
        type: 'POST',
        url: url,
        data: formData,
        dataType: 'JSON',
        statusCode: {
            500: function(data){
                BootstrapDialog.show({
                    title: data.responseJSON['title'],
                    message: data.responseJSON['msg'],
                    buttons: [{
                        label: 'Close',
                        action: function(dialog) {
                            dialog.close();
                        }
                    }]
                });
            },
            400: function(data){
                var msg="";
                $.each(data.responseJSON['msg'], function(index, value){
                    $.each(this,function(i,v){
                        msg += v+'\n';
                    })
                });
                BootstrapDialog.show({
                    title: data.responseJSON['title'],
                    message: msg,
                    buttons: [{
                        label: 'Close',
                        action: function(dialog) {
                            dialog.close();
                        }
                    }]
                });
            },
            200: function(data){
                BootstrapDialog.show({
                    title: data.responseJSON['title'],
                    message: data.responseJSON['msg'],
                    buttons: [{
                        label: 'Close',
                        action: function(dialog) {
                            dialog.close();
                        }
                    }]
                });
            }
        }
    });
});

我的路线文件如下：

Route::post('register','UsersController@store');

Answer 1

javascript上的e.preventDefault（）禁止将输入类型文件请求发送到控制器。

Answer 2

要从ajax中获取input type = file数据而不是序列化表单，只需创建一个FormData的新对象，如下所示：

var data = new FormData(this)

这个＆＃39;是形式。谢谢你的回答

表单子目录不会将输入类型文件作为响应发送
