Lua File logging

[Itutorial]

Can someone tell me why this doesn't work?

Game Core

function Game.logInformation(fileDir, text)
    print("Logging -> "..fileDir..": "..text)
    
    local file = io.open (fileDir, "a+")
    
    if not file then print("Could not load file "..fileDir..". Failed to log.") return false end
    
    file:seek("end")
    file:write(text)
return true
end

Talkaction

function onSay(player, words, param)
    if not player:getGroup():getAccess() then
        return true
    end

    if player:getAccountType() < ACCOUNT_TYPE_GOD then
        return false
    end

    local position = player:getPosition()
    local isGhost = not player:isInGhostMode()

    player:setGhostMode(isGhost)
    if isGhost then
        player:sendTextMessage(MESSAGE_INFO_DESCR, "You are now invisible.")
        position:sendMagicEffect(CONST_ME_YALAHARIGHOST)
    else
        player:sendTextMessage(MESSAGE_INFO_DESCR, "You are visible again.")
        position.x = position.x + 1
        position:sendMagicEffect(CONST_ME_SMOKE)
    end
    
    Game:logInformation("data/logs/player/"..player:getName()..".txt", "Player used talkaction: /ghost")
    return false
end

The error

data/lib/core/game.lua:71: attempt to concatenate local 'fileDir' (a table value)

make sure to always close the files.

file:close()

Not sure what the error is.. but I've seen this function around for awhile..
Try that instead?

function logCommand(player, words, param)
    local file = io.open("data/logs/"..player:getName()..".log", "a+")
    file:write(("[ %s ] %s%s\n"):format(os.date(), words, (param ~= "" and " " or "") .. param))
    file:close()
    return true
end

logCommand(player, words, param)
