/*** Add to Child Theme functions.php to show media caption under product thumbnails in the WooCommerce Product Gallery. ***/
 
add_filter('woocommerce_single_product_image_thumbnail_html', function($html, $attachment_id) {
  $caption = get_post_field('post_excerpt', $attachment_id);

  if(trim($caption)) {
    $html = str_replace('</div>', '<span class="gtnCaps">' . $caption . '</span></div>', $html);
  }

  return $html;
}, 10, 2);

Thanks works great

Thanks much, this is great.

It works for me too, using Woocommerce in combination with WPML in 2021. Translations are correct. Thanks a lot.

Thanks for the code! How can I edit the font size for this?

@fifionana3 - Just ID the CSS class via Web Inspector and change as needed. Sorry, I don't remember what it is off the top of my head. It might be "gtnCaps".

Thank you :)

Is there a way to display on main product only not gallery thumbnails?
