Showing total number of wishlist is very easy. Use addonify_wishlist_get_total_items() helper function to display total number of items in current users wishlist. If you also use .addonify-wishlist-count css class than the number will auto update when ever user adds or removes items from “addonify wishlist” plugin.

Example

<p class="addonify-wishlist-count">
  <?php echo addonify_wishlist_get_total_items(); ?>
</p>

	$btn_label .= ' (<span class="addonify-wishlist-count">' . $total_items . '</span>)';
	return $btn_label;
}
