Books for you

To complete implementing the recommendations system for the product details page, we need to update the
product.tpl template. Add the following lines at the end of presentation/templates/product.tpl.
After that, you can load TShirtShop and load a product details page. If that product has been ordered with
any other products, they??™ll show up in the recommendations list.
{if $obj->mRecommendations}

Customers who bought this also bought:

{section name=m loop=$obj->mRecommendations}

1. 
   {strip}
   
   {$obj->mRecommendations[m].product_name}
   
   {/strip}
   - {$obj->mRecommendations[m].description}
   

{/section}

{/if}
6. Open tshirtshop.css, and add the following style:
.list { color: #000000; }
7. Now, let??™s modify the cart_details componentized template to show product recommendations in the shopping
cart page. Open cart_details.php located in the presentation folder to add the $mRecommendation
member to the CartDetails class:
// Class that deals with managing the shopping cart
class CartDetails
{
// Public variables available in smarty template
public $mCartProducts;
public $mSavedCartProducts;
public $mTotalAmount;
public $mIsCartNowEmpty = 0; // Is the shopping cart empty?
public $mIsCartLaterEmpty = 0; // Is the 'saved for later' list empty?
public $mLinkToContinueShopping;
public $mUpdateCartTarget;
public $mRecommendations;
