Adding the View Cart Link to the Navigation

The second part of the Shopping Cart is very simple. You simply add a link that says “ view cart ” to the

main navigation if there are items in the customer ’ s Shopping Cart.

To do this, simply adjust the header view to look for contents in the cart session variable. If the cart

contains information, then show the link.

< a href=” < ?php echo base_url();? > ” >

< img src=” < ?php echo base_url();? > /images/logo.jpg” border=”0”/ >

< /a >

< div > < ?php echo anchor(“welcome/about_us”,”about us”);? > & nbsp;

< ?php echo anchor(“welcome/contact”, “contact”);? >

< ?php

if (count($_SESSION[‘cart’]) == true){

echo “ & nbsp;”. anchor(“welcome/cart”, “view cart”);

}
