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 🙂

$cart = WC()->cart->get_cart();

Where to add custom code?

You should place custom PHP in functions.php and custom CSS in style.css of your child theme: where to place WooCommerce customization?

This code still works, unless you report otherwise. To exclude conflicts, temporarily switch to the Storefront theme, disable all plugins except WooCommerce, and test the snippet again: WooCommerce troubleshooting 101
