WooCommerce: See What’s Inside the Cart Array (print_r)

So many times I needed to “play” with Cart contents in order to modify the default behaviour (such as removing a columns, hide the sale price to prices, hide an item, etc.).

There is a great PHP function that always helps – it’s called print_r and you can use this to “see” what’s inside the cart array, so that you can return certain information in a message for example.

A bit advanced, but as you grow your WooCommerce coding skills, you will use this a lot ๐Ÿ™‚

PHP Snippet: Print WooCommerce Cart Array


/**
 * @snippet       See what is inside the Cart array - WooCommerce
 * @how-to        Watch tutorial @ https://businessbloomer.com/?p=19055
 * @sourcecode    https://businessbloomer.com/?p=21941
 * @author        Rodolfo Melogli
 * @compatible    WC 2.6.14, WP 4.7.2, PHP 5.5.9
 */

add_action( 'woocommerce_before_cart', 'bbloomer_print_cart_array' );

function bbloomer_print_cart_array() {
$cart = WC()->cart->get_cart();
print_r($cart);
}

Where to add this snippet?

You can place PHP snippets at the bottom of your child theme functions.php file (before "?>" if you have it). CSS, on the other hand, goes in your child theme style.css file. Make sure you know what you are doing when editing such files - if you need more guidance, please take a look at my free video tutorial "Where to Place WooCommerce Customization?"

Does this snippet (still) work?

Please let me know in the comments if everything worked as expected. I would be happy to revise the snippet if you report otherwise (please provide screenshots). I have tested this code with Storefront theme, the WooCommerce version listed above and a WordPress-friendly hosting on PHP 7+.

  1. Hi Rodolfo! I read somewhere once that there’s a way to force line breaks to this array to make it easier to read, but I haven’t been able to find that snippet since – do you know it? Hope so! Oh and thanks for all that you do and share!!

    1. Hey Billy, thanks for your comment! YES! Try with:

      echo "<pre>";
      print_r($data);
      echo "</pre>";
