Show WooCommerce product tag name set for a product with a shortcode

If you have only one product tag set for each product, the following shortcode function will output the product tag term name set for the current product (or a string of coma separated term names, when there are multiple terms set for a product). It works also for a defined product Id as argument in the shortcode (see usage examples).

The function code:

add_shortcode( 'wc_product_tag', 'get_tag_term_name_for_product_id' );function get_tag_term_name_for_product_id( $atts ) {    // Shortcode attribute (or argument)    extract( shortcode_atts( array(        'taxonomy'   => 'product_tag', // The WooCommerce "product tag" taxonomy (as default)        'product_id' => get_the_id(), // The current product Id (as default)    ), $atts, 'wc_product_tag' ) );        $term_names = (array) wp_get_post_terms( $product_id, $taxonomy, array('fields' => 'names') );     if( ! empty($term_names) ){        // return a term name or multiple term names (in a coma separated string)        return implode(', ', $term_names);    }}

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

USAGE examples:

• For the current product: [wc_product_tag]
  or in php: echo do_shortcode('[wc_product_tag]');
• For a defined product id: [wc_product_tag product_id="37"]
  or in php: echo do_shortcode('[wc_product_tag product_id="37"]');

This also works for any product custom taxonomy, as WooCommerce product category…

To display WooCommerce product category term names set for a product you need to replace:

        'taxonomy'   => 'product_tag', // The WooCommerce "Product Tag" taxonomy (as default)

by the following line:

        'taxonomy'   => 'product_cat', // The WooCommerce "Product Category" taxonomy (as default)
