通过SKU添加可配置产品到购物车 - Magento

Question

我正在玩程序购物车娱乐。有没有将产品添加到购物车通过ID的问题，即

$params = array(
    'product' => 272, 
    'super_attribute' => array(
     22 =>30 , 
    ), 
    'qty' => 2, 
); 


$cart = Mage::getSingleton('checkout/cart'); 
$product = new Mage_Catalog_Model_Product(); 
$product->load(272); 
$cart->addProduct($product, $params); 
$cart->save(); 
Mage::getSingleton('checkout/session')->setCartWasUpdated(true); 

可是怎么办呢，如果我只知道产品SKU，我的意思是如何让产品ID和super_attributes可配置产品。

Mage::getModel('catalog/product')->loadByAttribute('sku','$sku'); 

似乎只返回该产品（SKU）信息和没有special_attribute。

任何想法？

你可以通过让集合，由SKU过滤检索产品：

$searchForThisSku = 'p_1234'; 

/** @var $productCollection Mage_Catalog_Model_Resource_Product_Collection */ 
$productCollection = Mage::getModel('catalog/product') 
    ->getResourceCollection() 
    ->addFieldToFilter('sku', $searchForThisSku); 

/** @var $product Mage_Catalog_Model_Product */ 
$product = $productCollection->getFirstItem(); 

// you should have the product now, maybe it isn't even necessary to get the ID 
$product->getId(); 

// all in one line: 
$productId = (int) Mage::getModel('catalog/product') 
    ->getResourceCollection() 
    ->addFieldToFilter('sku', $searchForThisSku) 
    ->getFirstItem() 
    ->getId();

尝试

/** @product Mage_Catalog_Model_Product */ 
$product = Mage::getModel('catalog/product'); 

$sku = 'sku'; 
$product->load($sku, 'sku'); 

Answer 3

我认为，feeela没回答问题。

一般（没有错误处理）：

$sku = 'any-sku-number'; 
$qty = 1; 

$product = Mage::getModel('catalog/product') 
    ->loadByAttribute('sku', $sku); 

$parentIds = Mage::getResourceSingleton('catalog/product_type_configurable') 
    ->getParentIdsByChild($product->getId()); 

$parent = Mage::getModel('catalog/product')->load(current($parentIds)); 

if ($parent->getTypeId() === Mage_Catalog_Model_Product_Type::TYPE_CONFIGURABLE) { 
    $paramsSuperAttribute = array('super_attribute' => array()); 

    foreach ($parent->getTypeInstance(true)->getConfigurableAttributes($parent) as $attribute) { 
     $paramsSuperAttribute['super_attribute'][$attribute->getProductAttribute()->getAttributeId()] = 
      (int) $product->getData($attribute->getProductAttribute()->getAttributeCode()); 
    } 
} 

$params = array('qty' => $qty); 

现在

，有两种方式通过SKU将产品添加到购物车：

编程：

$cart = Mage::getSingleton('checkout/cart'); 

$cart->addProduct(isset($parent) ? $parent : $product, array_merge($params, $paramsSuperAttribute))->save(); 

Mage::getSingleton('checkout/session')->setCartWasUpdated(true); 

通过网址：

$addToCartUrl = Mage::helper('checkout/cart') 
    ->getAddUrl(isset($parent) ? $parent : $product, $params); 

if (isset($parent)) { 
    $addToCartUrl .= '?' . http_build_query($paramsSuperAttribute); 
} 

// now you can use this url like this (controller action) 
$this->getResponse()->setRedirect($addToCartUrl); 
return;
