Display Variable Product Attributes and Terms on Woocommerce Archives

Question

I am trying to accomplish a attribute and term list on the shop page using the hook woocommerce_shop_loop_item_title. The goal is to get the attribute(s) and term(s

Answer 1

Uppdate 2020 - Removed an error when trying to get the term name from a term slug.

In your first code snippet there are some mistakes:

• the $product variable was not defined
• The function needed to be restricted to variable products only
• the $attributes_and_terms_names variable was not initialized…

Here is the revisited code (without the spaces between the rows):

add_action( 'woocommerce_shop_loop_item_title', 'variable_att_and_terms_on_loop');
function variable_att_and_terms_on_loop() {
    global $product;

    if( ! $product->is_type('variable') ) return; // Only for variable products

    $variation_attributes = $product->get_variation_attributes();

    if( sizeof($variation_attributes ) == 0 ) return; // Exit if empty

    $attributes = array(); // Initializing

    foreach( $product->get_variation_attributes() as $taxonomy => $terms_slug ) {
        $taxonomy_label = wc_attribute_label( $taxonomy, $product );

        $terms_name = array();

        foreach($terms_slug as $term_slug ) {
            // We try to get the term name when it's a term slug
            $term         = get_term_by('slug', $term_slug, $taxonomy);
            $terms_name[] = ! is_a($term, 'WP_Term') ? $term_slug : $term->name; 
        }
        $attributes[] = $taxonomy_label . ': ' . implode( ', ', $terms_name );
    }

    echo '
';
    echo '' . implode('
', $attributes) . '';
    echo '
';
}

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