Having no double things in a table

[Deltanic]

I always fail when I try something new, but normally I can fix the problem. Not now, I hope there's anyone who does know how to do the following:

I've made a table, but before adding something to the table, I want to know if it's already in there. So there will be no double things in the table. But how do I do that? This is what I have now, unworking. Still adds multiple values to the table: (Clientscript)

function someFunctionWithLoop ( )
local someTable = {} --The table
for _,v in ipairs ( something ) do --Loop
local name = getSomeString ( someElement ) -- Get some string
if name ~= table.find(someTable, 'name', name) then --If "name" isn't in the table
		someTable[v] = name --Add it
end
end
end
 
function table.find(t, ...) -- I got this function from the freeroam resource
local args = { ... }
if #args == 0 then
for k,v in pairs(t) do
if v then
return k
end
end
return false
end
 
local value = table.remove(args)
if value == '[nil]' then
	value = nil
end
for k,v in pairs(t) do
for i,index in ipairs(args) do
if type(index) == 'function' then
			v = index(v)
else
if index == '[last]' then
				index = #v
end
			v = v[index]
end
end
if v == value then
return k
end
end
return false
end

You can do:

if not table.find( someTable, "name", name ) then

I've tried that before, but it that isn't working either. It still has multiple values.

Well, maybe that example script wasn't wrong, so here's the script I'm using. Its a gridlist for every tuning part indeed. I know that this has been scripted for the freeroam mode already, but the one of the freeroam has a lot of code I don't need, or cod which is very difficult. So, I'm creating my own, with my own style.

function populateTuneGridlist ( ) --Function is triggered when pressing a GUI button. Only when you're in a vehicle.
guiGridListClear ( GUIPopupGrid_Grid ) -- Clear the gridlist, because this gridlist contains other lists too.
local theVehicle = getPedOccupiedVehicle ( getLocalPlayer ( ) ) -- Get the players vehicle
local upgradeType = {} -- The table
for _,upgrade in ipairs ( getVehicleCompatibleUpgrades ( theVehicle ) ) do -- The loop
	name = getVehicleUpgradeSlotName ( upgrade )
if not name == table.find ( upgradeType, "name", name ) then --Should be: If it cannot be find in the table, then do
local row = guiGridListAddRow ( GUIPopupGrid_Grid ) --Wheeeeeee, a lot of double upgradetypes in my gridlist. 
guiGridListSetItemText ( GUIPopupGrid_Grid, row, 1, name, true, false )
		upgradeType[upgrade] = name -- Add it to the table
end
end
showGridlistGUI ( ) --Show the gridlist, placed in another function
setElementData ( thisPlayer, "PopupType", "tune" ) --Gridlist contains the tune list now. thisPlayer = getLocalPlayer ( )
end

Why did you use:

if not name == table.find ( upgradeType, "name", name ) then

if I asked you to do:

if not table.find ( upgradeType, "name", name ) then

Though I didn't do that indeed (Misreading), it still doesn't work when using yours. Oh, and by the way, the console gives no errors.

You don't have any values with "name" inside the upgradeType table, so table.find will always return false. I just now understood what you're trying to do... You want this:

if not table.find( upgradeType, name ) then

Thnx I didn't thought that could be the problem.
