Lua variables in functions

[Stellow]

                local item = getItemIdByName(t[2])
doPlayerSendTextMessage(cid, MESSAGE_STATUS_CONSOLE_BLUE, item)

I already tested t[2], it is working as a string, but when I try to use inside a function, it return nothing.

this work: local item = getItemIdByName("blue robe")
local item = "blue robe"
this not: local item = getItemIdByName(item)


Edit:


local temp = "blue robe"
local item = getItemIdByName(temp)


work, but using the variable of my talkaction "t[2]" does not work. If I cout t[2] it shows the item name, but when I try to use it on the function, does not work.


part of the script:

local config = {
        levelRequiredToAdd = 20,
        maxOffersPerPlayer = 5,
        SendOffersOnlyInPZ = true,
        blocked_items = {2165, 2152, 2148, 2160, 2166, 2167, 2168, 2169, 2202, 2203, 2204, 2205, 2206, 2207, 2208, 2209, 2210, 2211, 2212, 2213, 2214, 2215, 2343, 2433, 2640, 6132, 6300, 6301, 9932, 9933}
        }
function onSay(cid, words, param, channel)
        if(param == '') then
                doPlayerSendTextMessage(cid, MESSAGE_STATUS_CONSOLE_BLUE, "Command requires param.")
                return true
        end
        local t = string.explode(param, ",")
        if(t[1] == "add") then
                if((not t[2]) or (not t[3]) or (not t[4])) then
                        doPlayerSendTextMessage(cid, MESSAGE_STATUS_CONSOLE_BLUE, "Command requires param.")
                        return true
                end

                        doPlayerSendTextMessage(cid, MESSAGE_STATUS_CONSOLE_BLUE, "You don't set valid price or items count.")
                        return true
                end
                if(string.len(t[3]) > 7 or (string.len(t[4]) > 3)) then
                        doPlayerSendTextMessage(cid, MESSAGE_STATUS_CONSOLE_BLUE, "This price or item count is too high.")
                        return true
                end
             local temp = t[2]
                local item = getItemIdByName(temp)
doPlayerSendTextMessage(cid, MESSAGE_STATUS_CONSOLE_BLUE, t[2])
                if(not item) then
                        doPlayerSendTextMessage(cid, MESSAGE_STATUS_CONSOLE_BLUE, "Item wich such name does not exists.")
                        return true

                        return true
                end
                if(getPlayerItemCount(cid, item) < (tonumber(t[4]))) then
                        doPlayerSendTextMessage(cid, MESSAGE_STATUS_CONSOLE_BLUE, "Sorry, you don't have this item(s).")
                        return true
                end
                local check = db.getResult("SELECT `id` FROM `auction_system` WHERE `player` = " .. getPlayerGUID(cid) .. ";")
                if(check:getID() == -1) then
                elseif(check:getRows(true) >= config.maxOffersPerPlayer) then

Maybe the t[2] does contain whitespaces. I would run your t[2] through a trim function before passing it to getItemIdByName().

function trim(s)
  return (s:gsub("^%s*(.-)%s*$", "%1"))
end
