Display the weight of each cart items in WooCommerce

问题

I'm using Woocommerce and I'm trying to display the product weight for each product on cart page.

I have used this:

add_action('woocommerce_cart_collaterals', 'myprefix_cart_extra_info');
function myprefix_cart_extra_info() {
    global $woocommerce;
    echo '<div class="cart-extra-info">';
    echo '<p class="total-weight">' . __('Total Weight:', 'woocommerce');
    echo ' ' . $woocommerce->cart->cart_contents_weight . ' ' . get_option('woocommerce_weight_unit');
    echo '</p>';
    echo '</div>';
}

It display the total cart weight. I would like to also show the weight of each item in the cart as well.

How to display the product weight of each item on cart page?

Thanks.

There is multiple ways to do it. You can use the custom function hooked in woocommerce_get_item_data filter hook to display the product weight of each cart items:

add_filter( 'woocommerce_get_item_data', 'displaying_cart_items_weight', 10, 2 );
function displaying_cart_items_weight( $item_data, $cart_item ) {
    $item_weight = $cart_item['data']->get_weight();
    $item_data[] = array(
        'key'       => __('Weight', 'woocommerce'),
        'value'     => $item_weight,
        'display'   => $item_weight . ' ' . get_option('woocommerce_weight_unit')
    );

    return $item_data;
}

*The Code goes in function.php file of your active child theme (or active theme). Tested and works.

To get the total line item weight (product weight x product quantity) replace:

$item_weight = $cart_item['data']->get_weight();

by:

$item_weight = $cart_item['data']->get_weight() * $product_qty;
