Display Woocommerce Custom Taxonomy

Hi, I’m trying to create a custom taxonomy for woocommerce product using the code below;

function add_gift_taxonomies() {
     // Add new "Locations" taxonomy to Posts
     register_taxonomy_for_object_type( 'product_gifts', 'product' );
     register_taxonomy('product_gifts', 'product', array(
       // Hierarchical taxonomy (like categories)
       'hierarchical' => true,
 	  'public'                     => true,
     'show_ui'                    => true,
     'show_admin_column'          => true,
     'show_in_nav_menus'          => true,
     'show_tagcloud'              => true,
       // This array of options controls the labels displayed in the WordPress Admin UI
       'labels' => array(
         'name' => _x( 'Gifts', 'taxonomy general name' ),
         'singular_name' => _x( 'Gift', 'taxonomy singular name' ),
         'search_items' =>  __( 'Search Gifts' ),
         'all_items' => __( 'All Gifts' ),
         'parent_item' => __( 'Parent Gift' ),
         'parent_item_colon' => __( 'Parent Gift:' ),
         'edit_item' => __( 'Edit Gift' ),
         'update_item' => __( 'Update Gift' ),
         'add_new_item' => __( 'Add New Gift' ),
         'new_item_name' => __( 'New Gift Name' ),
         'menu_name' => __( 'Gifts' ),
       ),
       // Control the slugs used for this taxonomy
       'rewrite' => array(
         'slug' => 'gifts', // This controls the base slug that will display before each term
         'with_front' => false, // Don't display the category base before "/locations/"
         'hierarchical' => true // This will allow URL's like "/locations/boston/cambridge/"
       ),
     ));
   }
   add_action( 'init', 'add_gift_taxonomies', 0 );

This code is based on an article from Smashing Magazine. There’s no problem in creating the taxonomy. All is well.

However, when trying to view the taxonomy, i got a “Page not found” error. Tried to add a new file taxonomy-product_gifts.php file in the child theme root folder with below code;

<?php
/**
 * The Template for displaying products in a product category. Simply includes the archive template
 *
 * This template can be overridden by copying it to yourtheme/woocommerce/taxonomy-product_cat.php.
 *
 * HOWEVER, on occasion WooCommerce will need to update template files and you (the theme developer).
 * will need to copy the new files to your theme to maintain compatibility. We try to do this.
 * as little as possible, but it does happen. When this occurs the version of the template file will.
 * be bumped and the readme will list any important changes.
 *
 * @see 	    http://docs.woothemes.com/document/template-structure/
 * @package 	WooCommerce/Templates
 * @version     1.6.4
 */

if ( ! defined( 'ABSPATH' ) ) {
	exit; // Exit if accessed directly
}

wc_get_template( 'archive-product.php' );

But still got page not found error.

Tried using solution found from Stackoverflow by modifying for mine as below;

add_filter('template_include', 'product_gifts_set_template');
   function product_gifts_set_template( $template ){
     if(is_tax('product_gifts')) :
       $taxonomy = 'product_gifts';
       $term = get_query_var($taxonomy);
       $prod_term = get_terms($taxonomy, 'slug='.$term.'');
       $term_slug = $prod_term[0]->slug;
       $t_id = $prod_term[0]->term_id;
       $term_meta = get_option( "taxonomy_$t_id" );
       $term_meta['product_gifts_access_pin'];

       wc_get_template( 'archive-product.php' );

    else :

       wc_get_template( 'archive-product.php' );

    endif;

   }

But still, not found.

Can anybody help me and tell me if there is anything wrong that I’m doing here? What am I missing here?

Thanks in advance!
