WooCommerce - Display total number of cart products in checkout

Question

I'm trying to display the total number of items a customer has in their cart on the checkout page.

I've read in the documentation that I need to use get_cart_contents_count but when I try this it outputs 1 no matter how many items I have.

NB: " get_cart_contents_count( ) Get number of items in the cart. Returns integer"

The code I have is:

add_action( 'woocommerce_before_checkout_billing_form', 'my_custom_checkout_field' );

function my_custom_checkout_field( $checkout ) {
    $_cartQty = count( WC()->cart->get_cart_contents_count( ) );
    echo $_cartQty;
} 

Any help would be appreciated as I thought I had been quite clever getting to this stage.

Answer 1

You have a count which is making it not work - try this:

function my_custom_checkout_field( $checkout ) {
    $_cartQty = WC()->cart->get_cart_contents_count( );
    echo $_cartQty;
} 

If I was you I would change it to:

function my_custom_checkout_field( $checkout ) {        
    return WC()->cart->get_cart_contents_count();
} 

I would never echo from a function like this - in general combining php and HTML like that is not any good.

I would <?= $class->my_custom_checkout_field() ?>
