файл сохраняется в архив в папке \files\yml\priceyml.zip
здесь берется допущение, что каждому товару соответствует одна категория и один производитель
в название товара подставляется префикс - имя категории в единственном числе - он находится в настройках магазина, название настройки для префикса - YMLPrices.Prefix+название категории
описание товара в прайсе - короткое описание товара в базе+ характеристики товара
также используются другие дополнительные настройки магазина - посмотрите код, увидите сами
следует также внести изменения в файл Libraries\Nop.BusinessLogic\Utils\PictureService.cs
в процедуре public string GetPictureUrl(Picture picture, int targetSize, bool showDefaultPicture)
поменять
url = CommonHelper.GetStoreLocation() + "images/thumbs/" + localFilename;
return url;
на
if (HttpContext.Current == null)
url = IoC.Resolve<ISettingManager>().StoreUrl + "images/thumbs/" + localFilename;
else
url = CommonHelper.GetStoreLocation() + "images/thumbs/" + localFilename;
return url;
в процедуре public string GetDefaultPictureUrl(PictureTypeEnum defaultPictureType, int targetSize)
return CommonHelper.GetStoreLocation() + "images/thumbs/" + fname;
на
if (HttpContext.Current == null)
return IoC.Resolve<ISettingManager>().StoreUrl + "images/thumbs/" + fname;
else
return CommonHelper.GetStoreLocation() + "images/thumbs/" + fname;
в свойстве public string LocalThumbImagePath получение значения заменить на
string path = "";
if (HttpContext.Current == null)
path = AppDomain.CurrentDomain.BaseDirectory + "images\\thumbs";
else
path = HttpContext.Current.Request.PhysicalApplicationPath + "images\\thumbs";
return path;
и в свойстве public string LocalImagePath получение значения заменить на
string path = "";
if (HttpContext.Current == null)
path = AppDomain.CurrentDomain.BaseDirectory + "images";
else
path = HttpContext.Current.Request.PhysicalApplicationPath + "images";
return path;
в процедуре public string GetDefaultPictureUrl(PictureTypeEnum defaultPictureType, int targetSize)
string relPath = CommonHelper.GetStoreLocation() + "images/" + defaultImageName;
заменить на
string relPath = "";
if (HttpContext.Current == null)
relPath = IoC.Resolve<ISettingManager>().StoreUrl + "images/" + defaultImageName;
else
relPath = CommonHelper.GetStoreLocation() + "images/" + defaultImageName;
ну и самое последнее - в web.config добавить строку в раздел <ScheduleTasks>
<Thread seconds="60">
<task name="GeneratYML" type="NopSolutions.NopCommerce.BusinessLogic.Utils.GenerateYMLTask, Nop.BusinessLogic" enabled="true" stopOnError="false" timeGenerate="14:00:00"/>
где timeGenerate - время запуска генерирования прайса
ps: забыл добавить - это все делалось в версии 1.9
pps: исправление описания -
в название товара подставляется префикс - имя категории в единственном числе - он находится в настройках магазина, название настройки для префикса - YMLPrices.Prefix+название страницы с категорией в поле SEName
