WooCommerce Cart Hooks – WPDesk

The “Add your own sections to the cart page” in WPDesk’s WooCommerce Cart Hooks article is very helpful in learning how add_action hooks code works in functions.php file.

WPDesk’s “WooCommerce Empty Cart Hooks – Visual Guide” is also especially helpful.

add_action( 'woocommerce_before_cart_table', 'wpdesk_cart_welcome_to_cart_text' );

In the above code, WPDesk helps me see that the first part (woocommerce_before_cart_table) is the WooCommerce hook, and the second part (wpdesk_cart_welcome_to_cart_text) links to the HTML in the function part of the overall code that goes in the functions.php file.

Full code from WPDesk that goes in the functions.php file:

/* https://www.wpdesk.net/blog/woocommerce-cart-hooks/ */
add_action( 'woocommerce_before_cart_table', 'wpdesk_cart_welcome_to_cart_text' );
 * Add "Welcome to Cart" text to WooCommerce cart page
function wpdesk_cart_welcome_to_cart_text() {
	echo '<div class="woocommerce-info">Welcome to Cart!</div>';
