How to validate if customer is in group

[Idiotic]

Hello,

in 1.6.1.6 I am trying to check if user is in group with id 6 using this:

controller:

'hisGroup' => ($this->context->customer->logged AND (Customer::getDefaultGroupId((int)$this->context->customer->id) == 6) ? true : false)

tpl: {if $hisGroup}...{/if}

although its not working. Do you have any idea why is that?

Thanks for reply.

Why you check group id in controller not in smarty?
