Get group in ParentOrderController

[Bartjuh1994]

Can someone help me to get the group ID / group Name in the ParentOrderController? I want to configure the order opc for a certain customer group like this:

if (Configuration::get('PS_ORDER_PROCESS_TYPE') == 0 && groupName != 'a' && strpos($_SERVER['PHP_SELF'], 'order.php') === false)
Tools::redirect('order.php');
if (Configuration::get('PS_ORDER_PROCESS_TYPE') == 1 && groupName == 'a' && strpos($_SERVER['PHP_SELF'], 'order-opc.php') === false)

See 'groupName != 'a' and groupname == 'a' in the code above.

 

Thanks in advance.
