如何用php创建分组产品？ （Magento 1.7）

Question

I'm trying to create grouped product and attach simple one to it. In admin section both of them are available, but in frontend available only simple product.

If I enter into product edit mode in admin panel (indifferent simple or grouped) and just save it without changing anything, grouped product will appear in frontend.

I can't figure out where is a problem.

// create grouped product
$product = Mage::getModel('catalog/product');
$product->setTypeId( 'grouped' );
$product->setAttributeSetId( 13 );
$product->setSku( 'K101596245' );
...
$product->setVisibility( 4 );
$product->setStatus( 1 );
$product->setTaxClassId( 0 );
$product->setStockData(array(
   'is_in_stock' => 0,
));
$product->save();
unset($product);


// create simple product
$simpleProduct = Mage::getModel('catalog/product');
$simpleProduct->setData( 'type_id', 'simple' );
...
$simpleProduct->setData( 'status', 1 );
$simpleProduct->setData( 'price', $values['retailPrice'] );
$simpleProduct->setData( 'special_price', $values['price'] );
$simpleProduct->setData( 'stock_data', array(
        'is_in_stock' => 1,
        'qty' => 9,
     ));
$simpleProduct->save();


// attach simple to grouped
Mage::getModel('catalog/product_link_api')->assign("grouped", $product->getId(), $simpleProduct->getId());

The same result with:

// attach simple to grouped
$relation_data = array();
$relation_data[ $simpleProduct->getId() ] = array('qty' => 9, 'position' => 0);
$product->setGroupedLinkData($relation_data);
$product->save();

Solution was found!

First script add grouped product, then simple. Stock of grouped product should be updated!

$stockItem = Mage::getModel('cataloginventory/stock_item')->loadByProduct($product->getId());
$stockItem->setData('is_in_stock', 1);
$stockItem->save();
