这里是Laravel新手，想请教如何一张一张上传多张图片。多张图片可在一个选择中使用，但将图片一张一张上传不起作用，并且第一张图片仅在提交后出现。请帮忙。

【问题讨论】：

你用的是什么版本的 laravel？
使用 Laravel 5.1
你不必为了上传多个文件而写这么多代码，如果你更新你的 laravel 版本会变得容易得多。

你可以这样做。

    $list_image = $temp = explode(",", $request->list_image);

if($request->hasfile('photos'))
        {
         $destinationPath = public_path('uploads/img/gallery/'. $add->id.'/'); 
            foreach($request->file('photos') as $k => $file)
            {

            $temp = explode(".", $file->getClientOriginalName());
            $newfilename = $file->getClientOriginalName();

            $key = array_search($newfilename, $list_image);
            if ($key == 0) {
                  $newfilename = $add->id . '_primary' . '.' . end($temp);
            } else {
                  $newfilename = chr(64 + $key) . '_' . $newfilename;
            }

                $name = $newfilename.'.'.$file->getClientOriginalExtension();           

                File::makeDirectory($destinationPath, $mode = 0777, true, true);
            $file->move($destinationPath, $name);
            $tdestinationPath = public_path('uploads/img/gallery/thumb'. $add->id.'/');
            try {
                    $img = Image::make($file->getRealPath());
                    $img->resize(50, 50, function ($constraint) {
                        $constraint->aspectRatio();
                    })->save($tdestinationPath.'/'.$name);      

                    $img->destroy(); 

                } catch (Exception $e) {
                    $response_data=array('images'=>"",'success'=>0,'message'=>$e->getMessage());
            }

                $image_arr[] = $name;
            }
            $uploaded_img = implode(',',$image_arr);    
            if(!empty($hidden_property_img)){
                $uploaded_img = $hidden_property_img.','.$uploaded_img;
            }   
            $data['images'] = $uploaded_img;    

        }
