11. Modify your presentation/templates/cart_details.tpl file to redirect the user to the checkout_info
page instead of PayPal. The Place Order button becomes the Checkout link:
...




{if $obj->mShowCheckoutLink}

{/if}

Total amount:  ${$obj->mTotalAmount}

Checkout

{/if}
...
12. Modify the CartDetails class in presentation/cart_details.php by adding two new public
members:
...
public $mRecommendations;
public $mLinkToCheckout;
public $mShowCheckoutLink = false;
CHAPTER 16 ?–  MANAGING CUSTOMER DETAILS 537
// Private attributes
private $_mItemId;
...
13. Update the init() method of the CartDetails class by deleting the PayPal code and adding the highlighted
code in its place (it??™s OK to delete it because we have placed the PayPal link code in checkout_info.php):
...
/* Calculate the total amount for the shopping cart
before applicable taxes and/or shipping */
$this->mTotalAmount = ShoppingCart::GetTotalAmount();
// Display Checkout link in the shopping cart
if ($this->mTotalAmount != 0 && Customer::IsAuthenticated())
{
$this->mLinkToCheckout = Link::ToCheckout();
$this->mShowCheckoutLink = true;
}
// Get shopping cart products
$this->mCartProducts =
ShoppingCart::GetCartProducts(GET_CART_PRODUCTS);
