Price:
{if $obj->mProduct.discounted_price != 0}
{$obj->mProduct.price}
{$obj->mProduct.discounted_price}
{else}
{$obj->mProduct.price}
{/if}

{if $obj->mLinkToContinueShopping}
Continue Shopping
{/if}

Find similar products in our catalog:

{section name=i loop=$obj->mLocations}

1. 
   {strip}
   
   {$obj->mLocations[i].department_name}
   
   {/strip}
   »
   {strip}
   
   {$obj->mLocations[i].category_name}
   
   {/strip}
   

{/section}

3. OK, now create the componentized template for the product details page in which the product with full
description and a second image will display. Create a file named product.php in the presentation
folder with the following contents:
// Handles product details
class Product
{
// Public variables to be used in Smarty template
public $mProduct;
public $mProductLocations;
public $mLinkToContinueShopping;
public $mLocations;
// Private stuff
private $_mProductId;
