Product Feature

Hello,



I want to change add to cart button with a URL which is stored in a feature called “url”.



how can I call features on frontend?



the way to call product attributes on magento is easily found on forums as below.


<?php [color=#1990B8]echo[/color] [color=#A67F59]$_product[/color][color=#A67F59]-[/color][color=#A67F59]>[/color][color=#2F9C0A]getAttributeName[color=#5F6364]([/color][/color][color=#5F6364])[/color] ?>

Thanks
