How to check if a feature is defined?

[darekm]

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'}


    SOMETHING


{/if} 
{/foreach}

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

{else}

do something else

{/if}

 

 

Is it supposed to be something like feature.isset? 

I'm talking about the product.tpl file.

 

Help!

Thanks.
