Display WooCommerce product attribute archive links on the product page, right below the add to cart button.

Add this code to your child theme’s functions.php file or via a plugin that allows custom functions to be added, such as the Dessky Snippets plugin. Please don’t add custom code directly to your parent theme’s functions.php file as this will be overwritten completely when you update the theme.

/**
 * Display product attribute archive links 
 */
add_action( 'woocommerce_product_meta_end', 'wc_show_attribute_links' );
// if you'd like to show it on archive page, replace "woocommerce_product_meta_end" with "woocommerce_shop_loop_item_title"

function wc_show_attribute_links() {
	global $post;
	$attribute_names = array( '<ATTRIBUTE_NAME>', '<ANOTHER_ATTRIBUTE_NAME>' ); // Add attribute names here and remember to add the pa_ prefix to the attribute name
		
	foreach ( $attribute_names as $attribute_name ) {
		$taxonomy = get_taxonomy( $attribute_name );
		
		if ( $taxonomy && ! is_wp_error( $taxonomy ) ) {
			$terms = wp_get_post_terms( $post->ID, $attribute_name );
			$terms_array = array();
		
	        if ( ! empty( $terms ) ) {
		        foreach ( $terms as $term ) {
			       $archive_link = get_term_link( $term->slug, $attribute_name );
			       $full_line = '<a href="' . $archive_link . '">'. $term->name . '</a>';
			       array_push( $terms_array, $full_line );
		        }
		        echo $taxonomy->labels->name . ' ' . implode( $terms_array, ', ' );
	        }
    	}
    }
}

Also remember to add the pa_ prefix to the attribute. An example would be: pa_color — or it wouldn’t work.

If you’d like to display this on the archive page, replace the add_action( 'woocommerce_product_meta_end', 'wc_show_attribute_links' ); with the following hook:

add_action( 'woocommerce_shop_loop_item_title', 'wc_show_attribute_links' );
