Show WooCommerce Product Attributes on Cart Page

Here are two examples for how to display product attributes on the WooCommerce Cart page. This uses a Woocommerce hook, ‘woocommerce_cart_item_name’, which will make the product attributes appear under the item name on the shopping cart (checkout) page. This goes in your functions.php file, not inside a template file.

Show All Product Attributes listed on new lines

This example shows all product attributes for each item listed under the item name, one attribute below the other (each attribute on a new line). For example:

Product Name
Attribute label 1: value
Attribute label 2: value
Attribute label 3: value

Here is the code for your functions file:

/**
* WooCommerce: show all product attributes listed below each item on Cart page
*/
function isa_woo_cart_attributes( $cart_item, $cart_item_key ) {
   
    $item_data = $cart_item_key['data'];
    $attributes = $item_data->get_attributes();
       
       
    if ( ! $attributes ) {
        return $cart_item;
    }
       
    $out = $cart_item . '<br />';
      
    foreach ( $attributes as $attribute ) {

        // skip variations
        if ( $attribute->get_variation() ) {
            continue;
        }
        $name = $attribute->get_name();
        if ( $attribute->is_taxonomy() ) {
                      
            $product_id = $item_data->get_id();
            $terms = wp_get_post_terms( $product_id, $name, 'all' );

            if ( ! empty( $terms ) ) {
                if ( ! is_wp_error( $terms ) ) {

                    // get the taxonomy
                    $tax = $terms[0]->taxonomy;

                    // get the tax object
                    $tax_object = get_taxonomy($tax);

                    // get tax label
                    if ( isset ( $tax_object->labels->singular_name ) ) {
                        $tax_label = $tax_object->labels->singular_name;
                    } elseif ( isset( $tax_object->label ) ) {
                        $tax_label = $tax_object->label;
                        // Trim label prefix since WC 3.0
                        $label_prefix = 'Product ';
                        if ( 0 === strpos( $tax_label,  $label_prefix ) ) {
                            $tax_label = substr( $tax_label, strlen( $label_prefix ) );
                        }
                    }
                    $out .= $tax_label . ': ';
                    $tax_terms = array();
                    foreach ( $terms as $term ) {
                        $single_term = esc_html( $term->name );
                        array_push( $tax_terms, $single_term );
                    }
                    $out .= implode(', ', $tax_terms). '<br />';

                }
            }
             
        } else {
         
            // not a taxonomy 
             
            $out .= $name . ': ';
            $out .= esc_html( implode( ', ', $attribute->get_options() ) ) . '<br />';
        }
    }
    echo $out;
}
   
add_filter( 'woocommerce_cart_item_name', isa_woo_cart_attributes, 10, 2 );

List All Product Attributes Separated by Comma

This example lists all the product attributes, side by side, separated by comma. It will list the attribute labels and values. For example:

Product Name
Attribute label 1: value, Attribute label 2: value, Attribute label 3: value

If you want to show only the values, without labels, then comment out lines 48 and 68, below.

/**
* WooCommerce: show all product attributes, separated by comma, on cart page

function isa_woo_cart_attribute_values( $cart_item, $cart_item_key ) {
 
    $item_data = $cart_item_key['data'];
    $attributes = $item_data->get_attributes();
     
    if ( ! $attributes ) {
        return $cart_item;
    }
     
    $out = $cart_item . '<br />';
     
    $count = count( $attributes );
     
    $i = 0;
    foreach ( $attributes as $attribute ) {
