Item that makes players vip

[andrew95434]

i have a vip system and it works perfectly. what i want to do is an item that you press and it gives you vip. i want that because i want that with premium points people could buy premium, so i make an item that makes you vip and i put this item to buy it with premium points. so... i have this script im libs folder in a file named vipsys.lua :

vip = {
name = "Vip system";
author = "Mock";
version = "1.0.0.0";
query="ALTER TABLE `accounts` ADD `vip_time` INTEGER";
query2="ALTER TABLE `accounts` ADD `vip_time` INT(15) NOT NULL"
}

function vip.setTable()
dofile('config.lua')
if sqlType == "sqlite" then
db.executeQuery(vip.query)
else
db.executeQuery(vip.query2)
end
end

function vip.getVip(cid)
assert(tonumber(cid),'Parameter must be a number')
if isPlayer(cid) == FALSE then error('Player don\'t find') end;
ae = db.getResult("SELECT `vip_time` FROM `accounts` WHERE `name` = '"..getPlayerAccount(cid).."';")
if ae:getID() == -1 then
return 0
end

local retee = ae:getDataInt("vip_time") or 0
ae:free()
return retee
end

function vip.getVipByAcc(acc)
assert(acc,'Account is nil')
local a = db.getResult("SELECT `vip_time` FROM `accounts` WHERE `name` = '"..acc.."';")
if a:getID() ~= -1 then
return a:getDataInt("vip_time") or 0, a:free()
else
error('Account don\'t find.')
end
end

function vip.setVip(cid,time)
dofile("config.lua")
assert(tonumber(cid),'Parameter must be a number')
assert(tonumber(time),'Parameter must be a number')
if isPlayer(cid) == FALSE then error('Player don\'t find') end;
db.executeQuery("UPDATE `"..sqlDatabase.."`.`accounts` SET `vip_time` = '"..(os.time()+time).."' WHERE `accounts`.`name` ='".. getPlayerAccount(cid).."';")
end

function vip.getVipByAccount(acc)
assert(acc,'Account is nil')
return db.getResult("SELECT `vip_time` FROM `accounts` WHERE `name` = '"..acc.."';"):getDataInt("vip_time") or 0
end

function vip.hasVip(cid)
assert(tonumber(cid),'Parameter must be a number')
if isPlayer(cid) == FALSE then return end;
local t = vip.getVip(cid) or 0
if os.time(day) < t then
return TRUE
else
return FALSE
end
end

function vip.hasVips(cid)
assert(tonumber(cid),'Parameter must be a number')
if isPlayer(cid) == FALSE then return end;
local t = vip.getVip(cid)
if os.time(day) < t then
return TRUE
else
return FALSE
end
end

function vip.accountHasVip(acc)
assert(acc,'Account is nil')
if os.time() < vip.getVipByAccount(acc) then
return TRUE
else
return FALSE
end
end
function vip.getDays(days)
return (3600 * 24 * days)
end

function vip.addVipByAccount(acc,time)
assert(acc,'Account is nil')
assert(tonumber(time),'Parameter must be a number')
local a = vip.getVipByAcc(acc)
a = os.difftime(a,os.time())
if a < 0 then a = 0 end;
a = a+time
return vip.setVipByAccount(acc,a)
end

function vip.setVipByAccount(acc,time)
dofile("config.lua")
assert(acc,'Account is nil')
assert(tonumber(time),'Parameter must be a number')
db.executeQuery("UPDATE `accounts` SET `vip_time` = '"..(os.time()+time).."' WHERE `accounts`.`name` ='"..acc.."';")
return TRUE
end

function vip.returnVipString(cid)
assert(tonumber(cid),'Parameter must be a number')
if isPlayer(cid) == TRUE then
return os.date("%d %B %Y %X ", vip.getVip(cid))
end
end

the function that makes you vip is "vip.addVipByAccount(acc, time)" but i tried and i couldnt insert it in a script of an item that gives you 30 vip days. this is all i want please help me i really need it.
