1. ТДС интернет магазин, настройки страницы, вставить перед:

$Shop_Controller_Show
	->limit($limit)
	->parseUrl();

Код:

$newPath = Core::$url['path'];
$partsPath = explode('/', $newPath);
$briefUrl = false;
 
if(count($partsPath) == 4)
{
    $partsPath = array_reverse($partsPath);
    $oItems = Core_Entity::factory('shop_item');
    $oItems->queryBuilder()
        ->where('shop_id', '=', 1)
        ->where('path', '=', $partsPath[1]);    
    $aoItems = $oItems->findAll();
 
    if(count($aoItems) == 1)    
    {
        $oldPath = $aoItems[0]->Shop->Structure->getPath() . $aoItems[0]->getPath();
        Core::$url['path'] = urldecode($oldPath);
        $briefUrl = true;
    }
    elseif(count($aoItems) > 1)
    {
        $oldPath = $aoItems[0]->Shop->Structure->getPath() . $aoItems[0]->getPath();
        Core::$url['path'] = urldecode($oldPath);
        $briefUrl = true;
 
        Core_Log::instance()
            ->clear()
            ->status(4)
            ->write("Найдено более одного товара с путём $partsPath[1], выводится первый из них");
    }
}

После:

$Shop_Controller_Show
	->limit($limit)
	->parseUrl();

Добавить:

Core::$url['path'] = $newPath;

Что бы сделать редирект на новый адрес. Нужно после

$Shop_Controller_Show
	->limit($limit)
	->parseUrl();

Добавить:

if($Shop_Controller_Show->item && $briefUrl == false )
{
	$view_item = $Shop_Controller_Show->item;
	$item_path = Core_Entity::factory('Shop_Item', $view_item)->path;
	$shop_path = $oShop->Structure->path;
	header("Location: /$shop_path/{$item_path}/");
	exit();	
}

2. Меняем в нужных XSLT шаблонах в shop_item ссылки. Вместо {url} вставить {/shop/url}{path}/.

3. Для того чтобы на карте сайта (/sitemap/) выводились товары с изменённым url, необходимо в ТДС Google SiteMap в настройках страницы создать новый класс, который наследуется от Core_Sitemap, и переопределить метод _structure в котором изменяется часть с url товара.

class Core_Sitemap_Ixta extends Core_Sitemap
{   
	protected function _structure($structure_id = 0)
	{
		$oSite = $this->getSite();
 
		$aStructure = $this->_selectStructuresByParentId($structure_id);
 
		$dateTime = Core_Date::timestamp2sql(time());
 
		$oSite_Alias = $oSite->getCurrentAlias();
 
		foreach ($aStructure as $oStructure)
		{
			$sProtocol = $oStructure->https
				? 'https://'
				: 'http://';
 
			$this->addNode($sProtocol . $oSite_Alias->name . $oStructure->getPath(), $oStructure->changefreq, $oStructure->priority);
 
			// Informationsystem
			if ($this->showInformationsystemGroups && isset($this->_Informationsystems[$oStructure->id]))
			{
				$oInformationsystem = $this->_Informationsystems[$oStructure->id];
 
				$offset = 0;
 
				do {
					$oInformationsystem_Groups = $oInformationsystem->Informationsystem_Groups;
					$oInformationsystem_Groups->queryBuilder()
						->select('informationsystem_groups.id',
							'informationsystem_groups.informationsystem_id',
							'informationsystem_groups.parent_id',
							'informationsystem_groups.path'
							)
						->where('informationsystem_groups.siteuser_group_id', 'IN', $this->_aSiteuserGroups)
						->where('informationsystem_groups.active', '=', 1)
						->where('informationsystem_groups.indexing', '=', 1)
						->offset($offset)->limit($this->limit);
 
					$aInformationsystem_Groups = $oInformationsystem_Groups->findAll(FALSE);
 
					$path = $sProtocol . $oSite_Alias->name . $oInformationsystem->Structure->getPath();
 
					foreach ($aInformationsystem_Groups as $oInformationsystem_Group)
					{
						$this->addNode($path . $oInformationsystem_Group->getPath(), $oStructure->changefreq, $oStructure->priority);
					}
					$offset += $this->limit;
				}
				while (count($aInformationsystem_Groups));
 
				// Informationsystem's items
				if ($this->showInformationsystemItems)
				{
					$offset = 0;
 
					do {
						$oInformationsystem_Items = $oInformationsystem->Informationsystem_Items;
						$oInformationsystem_Items->queryBuilder()
							->select('informationsystem_items.id',
								'informationsystem_items.informationsystem_id',
								'informationsystem_items.informationsystem_group_id',

								'informationsystem_items.path'
								)
							->open()

							->close()
							->where('informationsystem_items.siteuser_group_id', 'IN', $this->_aSiteuserGroups)
							->where('informationsystem_items.active', '=', 1)
							->where('informationsystem_items.shortcut_id', '=', 0)
							->where('informationsystem_items.indexing', '=', 1)
							->offset($offset)->limit($this->limit);
 
						$aInformationsystem_Items = $oInformationsystem_Items->findAll(FALSE);
						foreach ($aInformationsystem_Items as $oInformationsystem_Item)
						{
							$this->addNode($path . $oInformationsystem_Item->getPath(), $oStructure->changefreq, $oStructure->priority);
						}
 
						$offset += $this->limit;
					}
					while (count($aInformationsystem_Items));
				}
			}
 
			// Shop
			if ($this->showShopGroups && isset($this->_Shops[$oStructure->id]))
			{
				$oShop = $this->_Shops[$oStructure->id];
 
				$offset = 0;
 
				do {
					$oShop_Groups = $oShop->Shop_Groups;
					$oShop_Groups->queryBuilder()
						->select('shop_groups.id',
							'shop_groups.shop_id',
							'shop_groups.parent_id',
							'shop_groups.path'
							)
						->where('shop_groups.siteuser_group_id', 'IN', $this->_aSiteuserGroups)
						->where('shop_groups.active', '=', 1)
						->where('shop_groups.indexing', '=', 1)
						->offset($offset)->limit($this->limit);
 
					$aShop_Groups = $oShop_Groups->findAll(FALSE);
 
					$path = $sProtocol . $oSite_Alias->name . $oShop->Structure->getPath();
					foreach ($aShop_Groups as $oShop_Group)
					{
						$this->addNode($path . $oShop_Group->getPath(), $oStructure->changefreq, $oStructure->priority);
					}
 
					$offset += $this->limit;
				}
				while (count($aShop_Groups));
 
				// Shop's items
				if ($this->showShopItems)
				{
					$offset = 0;
 
					do {
						$oShop_Items = $oShop->Shop_Items;
						$oShop_Items->queryBuilder()
							->select('shop_items.id',
								'shop_items.shop_id',
								'shop_items.shop_group_id',
								'shop_items.shortcut_id',
								'shop_items.modification_id',
								'shop_items.path'
								)
							->open()
							->where('shop_items.start_datetime', '<', $dateTime)
							->setOr()
							->where('shop_items.start_datetime', '=', '0000-00-00 00:00:00')
							->close()

							->setOr()

							->close()
							->where('shop_items.siteuser_group_id', 'IN', $this->_aSiteuserGroups)
							->where('shop_items.active', '=', 1)
							->where('shop_items.shortcut_id', '=', 0)
							->where('shop_items.indexing', '=', 1)
							->offset($offset)->limit($this->limit);
 
						// Modifications
						if (!$this->showModifications)
						{
							$oShop_Items->queryBuilder()
								->where('shop_items.modification_id', '=', 0);
						}
 
						$aShop_Items = $oShop_Items->findAll(FALSE);
						foreach ($aShop_Items as $oShop_Item)
						{							
							$this->addNode($path . $oShop_Item->path . '/', $oStructure->changefreq, $oStructure->priority);
						}
 
						$offset += $this->limit;
					}
					while (count($aShop_Items));
				}
			}
 
			// Structure
			$this->_structure($oStructure->id);
		}
 
		return $this;
	}	 
}

И ниже уже используем новый класс:

$oCore_Sitemap = new Core_Sitemap_Ixta($oSite);

Вместо старого:

$oCore_Sitemap = new Core_Sitemap($oSite);
