Hi I've added an extra field to Product Descriptions using an edited version of the module product_extra_fields_1_6

Basically I've added extra_field_2 which is a copy of extra_field and updated the code/database accordingly to get it to display on product descriptions.

What I want to know is how would I get this field to display on product listings and other areas such as new products, special offers, products all, and featured products

I've attached my edited version of product_extra_fields_1_6 so you can see what I have done.

If you look in the code I've simply called the extra field extra_field_2 and to display it used
<?php if($extra_field_2!='') {
echo ''. $extra_field_2 . '';
} ?>

So I need to know how this can be displayed in modules > product_listing.php...or even if that is the right way to go.
