Display all product reviews on product page – Magento 1

To display product reviews on product page, first we want to edit catalog.xml found at app/design/frontend/YourPackage/YourTheme/layout/catalog.xml.

We want to add a new page block in catalog_product_view class. Inside this reference, add the following code:

<block type="review/product_view_list" name="product.info.product_additional_data" as="product_review" template="review/product/view/list.phtml"></block>

Then we want to add a single line of code on the product page in app/design/frontend/YourPackage/YourTheme/template/catalog/product/view.phtml at appropriate place.

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

To view product reviews on product page, just flush the Magento cache after editing these files.
