$reviewcollection = Mage::getModel('review/review')->getCollection()
->addStoreFilter(Mage::app()->getStore()->getId())
->setDateOrder()->addRateVotes();
$_items = $reviewcollection;
// echo "<pre>";print_r($_items->getData());echo "</pre>";
foreach ($_items as $_review) {
$_votes = $_review->getRatingVotes();
if (count($_votes)) {
foreach ($_votes as $_vote) {
echo $this->escapeHtml($_vote->getRatingCode());
echo "<br/>";
echo $_vote->getPercent();
}
}
}
?>
Update:
You can also try below code:
<?php
$votesCollection = Mage::getModel('rating/rating_option_vote')
->getResourceCollection()
->setReviewFilter(1)
->setStoreFilter(Mage::app()->getStore()->getId())
->load();
// echo "<pre>";print_r($votesCollection);echo "</pre>";
foreach ($votesCollection as $vote) {
# code...
echo "<pre>";print_r($vote);echo "</pre>";
}
?>
