Magento 1.9 – Display Review Tab in Product View Page

Not sure why this is, but I found that by including this <?php $_product = Mage::registry('product'); ?> above the code mentioned in the question. I was able to get it to work. I also moved all the code to it's own .phtml file so that it would only be included on the product view page by adding a couple lines to the local.xml Like so.

<catalog_product_view translate="label">
     <reference name="product.info">
        <block type="core/template" name="reviewCountTabBlock" template="catalog/product/view/tabs/review_count.phtml" />
    </reference>
</catalog_product_view>

Then on the view.phtml I added this:

    <?php echo $this->getChildHtml('reviewCountTabBlock') ?>

and in the new template catalog/product/view/tabs/review_count.phtml I added this:

    <?php $_product = Mage::registry('product'); ?>
<?php 
    // Add this code to get review count
    //$summary         = $this->getReviewsSummaryHtml($_product, false, true); 
    $reviewcount     = $_product->getRatingSummary()->getReviewsCount(); 
    $this->getLayout()->getBlock('product.info.tabs')->setReviewCount($reviewcount);
?>

And that cleaned everything up. I hope this helps others.

In catalog.xml ,

In <catalog_product_view translate="label"> handler

add below

<reference name="review_tabbed">
   <block type="review/form" name="tab_review_form" as="review_form" template="review/form.phtml" />
</reference>

In

 <block type="catalog/product_view_tabs" name="product.info.tabs" as="info_tabs" template="catalog/product/view/tabs.phtml" >
        ......
        ......
     </block>

Add below

<action method="addTab" translate="title" module="review" ><alias>review_tabbed</alias><title>Reviews</title><block>review/product_view_list</block><template>review/product/view/list.phtml</template></action>
