in PS 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 $hisGroup}...{/if}
although it's not working. Do you have any idea why is that?
With this code you are checked the customer´s default group. To checked if customer is in a group independently of default group try this
'inCustomerGroup' => in_array(4, Customer::getGroupsStatic($this->context->cart->id_customer)) ? true : false,
