Magento: 获取产品评论 get all reviews with review summary

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
