1. 根据产品id获取该产品评论

$productId = 1234;
$product = Mage::getModel('catalog/product')->load($productId);$storeId = Mage::app()->getStore()->getId();
Mage::getModel('review/review')->getEntitySummary($product, $storeId);$ratingSummary = $product->getRatingSummary();
print_r($ratingSummary->getData());

结果是：

Array
([primary_id] => 27[entity_pk_value] => 16[entity_type] => 1[reviews_count] => 3[rating_summary] => 51[store_id] => 1
)

结果解释如下：

//Entity id of a summary review
["primary_id"] => string(3) "27"
//
//Product id
["entity_pk_value"] => string(3) "16"
//
//Entity type id: 1-Product; 2-Customer; 3-Category
["entity_type"] => string(1) "1"
//
//Qty of reviews
["reviews_count"] => string(1) "3"
//
//Summarized rating: the percentage which represents number of stars, each 20% step fills up one star
["rating_summary"] => string(2) "51"
//
//Store id
["store_id"] => string(1) "1"

或者简单点：

<?php
$storeId    = Mage::app()->getStore()->getId();
$summaryData = Mage::getModel('review/review_summary')->setStoreId($storeId)->load($productId);
if($summaryData->getRatingSummary()){
?><div class="rating-box" style="float:left;"><div class="rating" style="width: <?php echo $summaryData->getRatingSummary().'%'; ?>"></div></div>
<?php  } ?>

2. 获取所有评论

function getReviews() {$reviews = Mage::getModel('review/review')->getResourceCollection();$reviews->addStoreFilter( Mage::app()->getStore()->getId() )->addStatusFilter( Mage_Review_Model_Review::STATUS_APPROVED )->setDateOrder()->addRateVotes()->load();        return $reviews;
}

结合上面的函数，我自己使用的例子如下：

$home_reviews = array();
$storeId      = Mage::app()->getStore()->getId();
$reviews      = Mage::getModel('review/review')->getCollection()->addStoreFilter($storeId)->addStatusFilter(Mage_Review_Model_Review::STATUS_APPROVED)->setPageSize(5)->setCurPage(1)->setDateOrder();foreach($reviews as $key=>$review)
{$home_reviews[$key]           = $review->getData(); $home_reviews[$key]['rating'] = Mage::getModel('review/review_summary')->setStoreId($storeId)->load($review->getEntityPkValue())->getRatingSummary();$home_reviews[$key]['rate']   = number_format($home_reviews[$key]['rating']*5/100,1);
}

这个例子结合了几个条件，1. 状态是 APPROVED   2. 时间排序，最新在前   3. 只获取前五个
