Return total number of items in Cart

Return total Amount of Shopping Cart Items in Magento

Sometimes you run into tiny idiosyncracies in Magento templates. It makes you question many things. Such as: why would a theme developer choose to only show the total amount of different types of products in the minicart.phtml?

Today I’m showing you different ways to return the total amount of items in your customer’s shopping cart for usage anywhere within your store’s template.

Example: you have a store that sells fruit and bicycles. I suppose we’re serving a niche there, which doesn’t make any sense. But it doesn’t make any sense either to show your customer this receipt after purchase:

Purchases:
- 2 types of fruit
- 3 types of bicycles
Total: 2 different types of products

Besides showing a total price. A total of 5 items would make much more sense than showing the total amount of different producttypes, wouldn’t it?

Appearantly some themedevelopers disagree, because they tend to use the following Magento function in their mini-cart:

$_cartQty = $this->helper('checkout/cart')->getItemsCount(); // Shows the different kind of items in cart (NOT TOTAL!)

When the more logical choice would be:

$_cartQty = $this->helper('checkout/cart')->getSummaryCount(); // Shows the total amount of items in cart

This should work in most cases. But if you’re unlucky, like me, this doesn’t work. In that case, try:

$_cartQty = Mage::getModel('checkout/cart')->getQuote()->getItemsQty();

This is a solid way of displaying the total amount of items in Magento’s shopping cart. But it needs a little tweaking, as it could display the value followed by four decimals, e.g. 3.0000.

You can strip the decimals (everything after the dot) by wrapping it in a round-function:

$_cartQty = round(Mage::getModel('checkout/cart')->getQuote()->getItemsQty(), 0);

To increase readability you could also do the following:

$_cartQty = Mage::getModel('checkout/cart')->getQuote()->getItemsQty();
$_cartQty = round($_cartQty, 0);

There you have it. A bulletproof way of returning the total amount of items in Magento’s cart for usage anywhere on your site. Including the mini-cart in the top-right of your rwd based theme.
