Cart Quantity On Page

[kerry]

I have created the cart from the book (as per the code) and this works great, but on every page I would like for example, "You have 2 items in your cart" which is taking the quantity from the cart.

 

Do you have any code on how this can be achieved on every page?

 

Thanks

I can't remember the precise code for this example. But I think the data is stored in the $_SESSION. So you can query the $_SESSION to see if it's empty. If it isn't then query the $_SESSION to find out how many items you have and print this to the page.

I tried this, but no quantities are shown:

 

<?php $_SESSION['cart'][$row['quantity]];
echo "<p>There are {$row['quantity']} items in your basket</p>";
?>

Items are stored in $_SESSION['cart'], with each item being a single element in that array. To get the number of items, you could use count($_SESSION['cart']). However, that wouldn't reflect if there were multiple copies of an item in the cart. To get that, you'd need to loop through the $_SESSION['cart'] array and add up all the individual items.
