Get product_id of associated product added in cart

Question

I have a configurable product and I want to capture the data of the associated product which is added to cart.

http://manoolia.dmcs-online.com/zig-zag-configurable?___store=english&___from_store=english

On this example, when you chose green and add it to cart, a popup will display with the red image(configurable product image). I want to get the associated product image etc.

Any idea?

Answer 1

If you want to show simple product thumbnail in shopping cart than you can change configuration on below path:

you will find this option in shopping cart section as define below.

system->configuration->sales->checkout->shopping cart tab.

Answer 2

Have a look in Mage_Sales_Model_Quote_Item_Abstract::getChildren, you should be able to use it to get the first child of a configurable which will be it's associated simple, then get whatever data you require.

Something like the following:

$helper = Mage::helper('catalog/image');

//However you get the quoteItem, it goes here!
$quoteItem = Mage::getModel('sales/quote_item');

$imageUrl = $helper->init($quoteItem->getProduct(), 'small_image');

if ($quoteItem->getData('product_type') == Mage_Catalog_Model_Product_Type::TYPE_CONFIGURABLE) {

    $children = $quoteItem->getChildren();
    $childQuoteItem = reset($children);
    if ($childQuoteItem) {
        $imageUrl = $helper->init($childQuoteItem->getProduct(), 'small_image');
    }
}
