Frontend – Rating Not Showing on Review Block

To get Rating Array Try the Below Code.

$prod=Mage::getSingleton('catalog/product')->load('your Prodouct Id');
$productId = $prod->getId();
$reviews = Mage::getModel('review/review')
            ->getResourceCollection()
            ->addStoreFilter(Mage::app()->getStore()->getId())
            ->addEntityFilter('product', $productId)
            ->addStatusFilter(Mage_Review_Model_Review::STATUS_APPROVED)
            ->setDateOrder()
            ->addRateVotes();


    if (count($reviews) > 0) {
        foreach ($reviews->getItems() as $review) {
            foreach( $review->getRatingVotes() as $vote ) {
                $ratings[] = $vote->getPercent();
            }
        }
    print_r($ratings);
}

It seems that when you disable Mage_Review then Mage_Rating also gets disabled.

You can manually remove the review form by editing the following template file:

app/design/frontend/YOUR_PACKAGE/YOUR_THEME/template/review/form.phtml

The review form is submitted to postAction() of class Mage_Review_ProductController (app/code/core/Mage/Review/controllers/ProductController.php).
