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");
}
?
