See it Live: Go to my demo shop and add ten of any item to your cart. You will immediately see the discount because of Discount Preview. Without Discount Preview, the discount would not be visible until the Order Confirmation Page.

Shopping Cart Page With the Discount Preview Extension

Shopping Cart box With Discount Preview Extension

Ordinary Shopping Cart Page

The discounts are shown as line items below the subtotal on the Shopping Cart page, and in the Shopping Cart box (when not on the Shopping Cart page). Note that on the Shopping Cart page, the box appears as before, since the preview is shown in the main body of the page.

Installation Instructions:

1. Back up everything! Try this in a test environment prior to installing it on a live shop.
2. Copy the contents of the unzipped folder to the root directory of your shop. All the files are new.
3. Edit the file catalog/shopping_cart.php, and underneath the row for the line that prints SUB_TITLE_SUB_TOTAL, add

   <?php
     require("discount_preview.php"); 
   ?>
   

   
   So your catalog/shopping_cart.php file will look like this: ...

         <tr>
           <td align="right" class="main"><b><?php echo SUB_TITLE_SUB_TOTAL; ?> 
               <?php echo $currencies->format($cart->show_total()); ?></b></td>
         </tr>
   <?php
     require("discount_preview.php"); 
   ?>
   

4. Edit the file catalog/includes/boxes/shopping_cart.php. Just before the close of the block that prints the subtotal, add

       require_once('discount_preview.php'); 
   

   
   So your catalog/includes/boxes/shopping_cart.php file will look like this:

     if ($cart->count_contents() > 0) {
       $info_box_contents[] = array('text' => tep_draw_separator());
       $info_box_contents[] = array('align' => 'right',
                                    'text' => $currencies->format($cart->show_total()));
       require_once('discount_preview.php'); 
     }
   

5. Because the shopping cart box cannot show the discount on the shopping cart page, I recommend not displaying the shopping cart box on the shopping cart page. At the top of catalog/includes/boxes/shopping_cart.php, add

   <?php
      if ($current_page != FILENAME_SHOPPING_CART) {
   ?>
   

   with a closing

   <?php
      } 
   ?>
   

   at the end of the file.
6. You're done! Test it out by adding some items to a cart and looking at the shopping cart page.
