Lua Include extra text in an item description

[CastorFlynn]

The default script overwrites the item description with the buyer's name. How do I keep the original description and include the buyer's name with it?
For example:

You see a helmet of the ancients (Arm:8).
It weighs 27.60 oz.
The gem of the helmet is burned out and should be replaced. (Bought by John)

function addItem(player, transactionId, itemId, itemCount, offerId)
    local _itemId = tonumber(itemId)
    local _itemCount = tonumber(itemCount)
    local _offerId = tonumber(offerId)
        
    local playerName = player:getName()
    
    local deliver = deliverItem(player, _itemId, _itemCount)
    local itemName = ItemType(_itemId):getName()
    
        if deliver.item then
            deliver.item:setAttribute('description', ('Bought by %s.'):format(playerName))
        end
end

Not sure about function names, but you can probably find out

function addItem(player, transactionId, itemId, itemCount, offerId)
    local _itemId = tonumber(itemId)
    local _itemCount = tonumber(itemCount)
    local _offerId = tonumber(offerId)
        
    local playerName = player:getName()
    
    local deliver = deliverItem(player, _itemId, _itemCount)
    local itemName = ItemType(_itemId):getName()
    
    if deliver.item then
        local currentDesc = deliver.item:getAttribute('description');
        local boughtBy = '(Bought by %s)':format(playerName);
        deliver.item:setAttribute('description', currentDesc .. ' ' .. boughtBy);
    end
end

Thanks for answering.

There was an error on one line:

/data/scripts/globalevents/shop.lua:150: unexpected symbol near ':'

Line 150:

local boughtBy = '(Bought by %s)':format(playerName);

 

[Roddet]

local boughtBy = ('Bought by %s'):format(playerName)

 

[CastorFlynn]

local boughtBy = ('Bought by %s'):format(playerName)

There was no error now, but he just put "Bought by" in the item description.

Apparently the code is not finding the original description to insert into the currentdesc variable.

If I use

deliver.item:setAttribute('description', 'Hi' .. currentDesc)

the description appears only as: Hi
but if use

deliver.item:setAttribute('description', 'Hi' .. boughtBy)

appears as: Hi Bought by player

So I believe there is something wrong with returning the original description for currentDesc variation.

local oldDescription = deliver.item:getAttribute("description") == "" and ItemType(itemId):getDescription() or deliver.item:getAttribute("description")
local newDescription = oldDescription .." (Bought by ".. playerName ..")"
deliver.item:setAttribute('description', newDescription)

if an item still has it's original description and it wasn't manipulated through setAttribute then getAttribute will just return an empty string, you have to use ItemType(itemid):getDescription() to get the original description then

 

[CastorFlynn]

local oldDescription = deliver.item:getAttribute("description") == "" and ItemType(itemId):getDescription() or deliver.item:getAttribute("description")
local newDescription = oldDescription .." (Bought by ".. playerName ..")"
deliver.item:setAttribute('description', newDescription)

if an item still has it's original description and it wasn't manipulated through setAttribute then getAttribute will just return an empty string, you have to use ItemType(itemid):getDescription() to get the original description then

That worked! Thanks!
