Magento – Accessing a customer’s wishlist
$wishList = Mage::getSingleton('wishlist/wishlist')->loadByCustomer($customer);
$wishListItemCollection = $wishList->getItemCollection();
if (count($wishListItemCollection)) {
$arrProductIds = array();
foreach ($wishListItemCollection as $item) {
/* @var $product Mage_Catalog_Model_Product */
$product = $item->getProduct();
$arrProductIds[] = $product->getId();
}
}
The array variable $arrProductIds will now contain the list of all Product IDs that have been wishlisted by that specific Customer.
