How to check if a feature is defined?


Recommended Posts

Hi, I would like to determine if a feature has been set for the product via smarty. 

I used to do that like this:

{foreach from=$features item=feature}  {if $feature.name == 'is_credit'}



But this time I need a if/else check to determine if a variable exists; not by going through them one by one.


Like this:


{if this feature is set}

do that


do something else




Is it supposed to be something like feature.isset? 

I'm talking about the product.tpl file.
