            $marketing_material->title                           = Input::get('title');

            dd($old_title);

            $marketing_material->save();


            return Redirect::to('marketing_materials')
            ->with('success','The electronic marketing material was updated succesfully!');
        }
    }

目标：

能够编辑上传的文件（已上传的文件）。

控制器 - ＆gt;更新功能

正如你所看到的，我依靠我的目标路径，在我的标题上，一旦用户更改标题，一切都会搞砸。

我不确定如何解决这个问题。

问题：

有人可以告诉我如何在Laravel 4中解决这个问题，还是指向正确的方向？

感谢。

    public function update($id)
{
    $validator = CatalogDownload::edit_validator(Input::all());

    if ($validator->fails()) {
        return Redirect::to('catalog_downloads/'. $id . '/edit')
        ->withErrors($validator);

    }else {


        $catalog_download        = CatalogDownload::findOrFail($id);
        $catalog_download->title = Input::get('title');
        $catalog_download->note  = Input::get('note');

        $catalog_download->save();





        foreach (ExportType::all() as $export_type)
        {




            if (Input::hasFile('type_' . $export_type->id))
            {



                $success = File::deleteDirectory(base_path().'/app/files/product_export/'. $catalog_download->id.'/'. $export_type->id.'/'); // Answer





                $product_export  = new ProductExport;

                $zip             = Input::file('type_' . $export_type->id);
                $filename        = $zip->getClientOriginalName();
                $filesize        = $zip->getSize();

                $destinationPath = base_path().'/app/files/product_export/'. $catalog_download->id.'/'. $export_type->id.'/';
                $uploadSuccess   = $zip->move($destinationPath, 'Bioss 2015 Catalog.zip' );




                if  (!isset($uploadSuccess )) 
                {
                    return Redirect::to('catalog_downloads/create')
                    ->with('error', 'Problem during upload')
                    ->withInput();          
                }


                $product_export->file_path           =  'Bioss 2015 Catalog.zip';

                $product_export ->exported_date      = DateHelper::getDateFormatMySQL(Input::get('exported_date'));
                $product_export->catalog_download_id = $catalog_download->id;
                $product_export->export_type_id      = $export_type->id;




                $product_export->size                = $filesize;




                $product_export->save();
            }


        }


        return Redirect::to('catalog_downloads/')
        ->with('success','The catalog_download was updated successfully!');

    }
}

上面的代码就是它的解决方案。

魔术发生在这一行：

$success = File::deleteDirectory(base_path().'/app/files/product_export/'. $catalog_download->id.'/'. $export_type->id.'/');

我删除了旧文件，然后重新创建新文件。
