Get the Product tags for the current product only in WooCommerce

You can use the function wp_get_post_terms() function for WooCommerce 'product_tag' custom taxonomy and a defined product id this way:

$output = array();// get an array of the WP_Term objects for a defined product ID$terms = wp_get_post_terms( get_the_id(), 'product_tag' );// Loop through each product tag for the current productif( count($terms) > 0 ){    foreach($terms as $term){        $term_id = $term->term_id; // Product tag Id        $term_name = $term->name; // Product tag Name        $term_slug = $term->slug; // Product tag slug        $term_link = get_term_link( $term, 'product_tag' ); // Product tag link        // Set the product tag names in an array        $output[] = '<a href="'.$term_link.'">'.$term_name.'</a>';    }    // Set the array in a coma separated string of product tags for example    $output = implode( ', ', $output );    // Display the coma separated string of the product tags    echo $output;}

Tested and works.

You can replace get_the_id() by a dynamic product Id variable too.

You can now use the wc_get_product_tag_list() function to get a list of the product's tags. It supports providing a separator along with before and after elements.

Example

<?php    global $product;?>    <div class="product-tags">        <?php echo wc_get_product_tag_list( $product->get_id(), ', ' ); ?>    </div>
