Magento: Display reviews on product detail page

By default Magento will display all of your product reviews on a separate dedicated reviews page. In most cases you’ll find that the design caters for some/all of the product reviews to be displayed somewhere on the product detail page. Commonly they are found in a tab towards the bottom page, along with a link to the aforementioned full review page.

 Register XML Block

First you’ll need to add a block to your XML in your template file – this will tell Magento where to find your files. I normally do this in my local.xml file but that’s just personal preference – you can add this to your catalog.xml file if you prefer;

<catalog_product_view>
    <reference name="product.info">
        <block type="review/product_view_list" name="product.info.product_additional_data" as="reviews" template="review/product/view/review_summary.phtml" />
    </reference>
</catalog_product_view>

 Create review_summary.phtml

Next you will need to create review_summary.phtml which we registered in the above XML. It should be saved here;

app/design/frontend/default/YOURTHEME/review/product/view/review_summary.phtml

Create review collection

And finally load your collection, and style accordingly

$ReviewsCollection = $this->getReviewsCollection()->getItems();

if( count( $ReviewsCollection ) ) {
    $x = 1;

    foreach( $ReviewsCollection as $_review ){

        // get review title
        echo $_review->getTitle();

        $_votes = $_review->getRatingVotes();
        if (count($_votes)){
            foreach ($_votes as $_vote){
                echo $_vote->getRatingCode().' - '.$_vote->getPercent().'%<br />';
            }
        }

        // get review date
        echo $this->formatDate($_review->getCreatedAt()).'<br />';

        // get review detail
        echo $_review->getDetail().'<br />';

        // get how wrote the review
        echo $_review->getNickname().'<br />';

        // because you cant setPageSize with this collection it's best to break the loop.
        if($x == 4){ break; }

        $x++;
    }
}

 Display product review collection

And finally, to display your newly created review block simply add the below code to your product view.

echo $this->getChildHtml('reviews');
