Hi,

I want to make staff to see/edit their own orders only,
I use hikashop to manage orders which we create for customers via phone, So
1- I need to know which staff created this or that order. DONE
2- I want to make staff see and edit their own orders only. YET
3-I want to to edit any order to make it disappear from one staff to another. DONE - By Fabrik.

I made number one with no problem with this plugin + making No-List fields "id = id of who created order" "staff = name of who created id" through HikaCustomFields.

<?php
class plgHikashopstaff extends JPlugin {
	function plgHikashopName(&$subject, $config){
		parent::__construct($subject, $config);
	}
	function onAfterOrderCreate(&$order,&$send_email) {
           $user = JFactory::getUser();
	   $staff = new stdClass();
           $staff->order_id = $order->order_id;
           $staff->staff = $user->name;
           $staff->id = $user->id;
           $result = JFactory::getDbo()->updateObject('#__hikashop_order', $staff, 'order_id');
	}
}
?>

If (access group is SuperUser){
Select all
}elseif (access group is Spical){
select where id =Joomla-Current-User-ID
}
