How to know number of items added to cart in WordPress shopping cart with SHOPP PLUGIN

3 comments

1. I added a code to count the number of items in cart and output them.

   Hope it helps!

   <p class="cartinfo">
       <?php if (shopp('cart','hasitems')): ?>
         <?php $total_items = 0; ?>
         <?php while(shopp('cart','items')): ?>
           <?php $total_items = $total_items + 1; ?>
         <?php endwhile; ?>
       <?php echo $total_items;?> <?php if ($total_items = 1) {echo'Item';} else {echo'Items';} ?> (<?php shopp('cart','subtotal'); ?>)
   
       <?php else: ?>
       0 Items in Cart :(
       <?php endif; ?>
       </p>

2. I think this does what you want?

   <?php shopp('cart','totalitems'); ?>
   

   Here are the docs on it: Cart_Tags#totalitems

   UPDATED: The docs are now open to the public and updated. Here is a new link for the same function. Note the ‘alternative forms’ available: shopp(‘cart’,’total-items’)

3. This part has always been a little confusing in Shopp.

   If you need the number of unique items in the cart you should use

   shopp('cart','totalitems','options...');
   

   (for example: 5 apples, 3 pears, 2 carrots would result in 3)

   If you need the number of items in the cart you should use

   shopp('cart','total-quantity','options...');
   

   (for example: 2 apples, 3 pears, 1 carrot would result in 6)

   To use the value in a variable, set options to 'return=true'
