Associating multiple values with a single key in a dictionary

Help and Feedback Scripting Support
#1

Basically, I’m trying to store an array in a key in a dicitionary, but whenever I check the length of the array it shows up as 0 with no values instead of 3.

#2

Show us the code so we can understand what you’re talking about.

Here’s how you should be doing it (from what your explanation says)

local dictionary = {
	
}

dictionary["Tab"] = {"Value1", "Value2", "Value3"}

print(#dictionary["Tab"])

Can you provide the code?

sksks 30 character minimum

#4

Yes, give me 5 minutes as I have to screenshot the client and the server.

#5

Don’t screenshot. Instead, copy and paste it here. Make sure to format it surrounded with ``` so it highlights!

CLIENT

for i,v in pairs (orderingFrame.border.optionsScroller:GetChildren()) do
	if v:IsA("TextButton") then
	v.MouseButton1Down:Connect(function()
		if #chosen < 5 then
		orderingFrame.choices:FindFirstChild("item".. tostring(#chosen + 1)).Text = v.Name
			orderingFrame.choices:FindFirstChild("item".. tostring(#chosen + 1)).Visible = true
		table.insert(chosen,v)
		else print("too many items!")
		end
	end)
	end
end

SERVER

	if event == "destroy" then
		plr.PlayerGui:FindFirstChild("orderingSystem"):Destroy()
	end
	if event == "claimOrder" then
	local order = findOrder(info1)
	plr.makingOrderFor.Value = info1
	plr.isMakingOrder.Value = true
	if order then
		
		order.status.Green.Visible = true
	
		order.status.Red.Visible = false
		
		order.status.Text = "CLAIMED"
	
		updateBoardForAll()
	
	end
	end
end)

later in the script

if  playerHasAllItems(secondplayer,itemsNeeded) then
		
		firstplayer.makingOrderFor.Value = ""
		firstplayer.isMakingOrder.Value = false
		removeItemFromTable(orders,secondplayer.Name)
		findOrder(secondplayer.Name):Destroy()
		updateBoardForAll()
		end

“the playerHasAllItems function”

function playerHasAllItems(plr,array)
	local missingOne = false
	print(#array)
	for i = 1,#array do
		if plr.Backpack:FindFirstChild(tostring(array[i])) then
		else
			missingOne = true
		end
	end
	if missingOne == true then return false
	else
		return true
	end
end

Was the # in (#dictionary[“Tab”[) a type? Because that’s probably the problem then.

#8

Not too sure what you mean by Type, # just prints the length…

#9

Does it need to be in that format for it to be printed correctly?

#10

From what I am aware yes, it really depends on your method.

#11

what is the problem on wiki you can read dictionary can have any data type so

local d = {
[“key”]={“value1”,“value2”,“value3”}
}
and find it by
local resultd=d[“key”]
local result1=resultd[1]
local result2=resultd[2]
local result3=resultd[3]

#12

The unary length operator # doesn’t work on a dictionary because your entries are stored in the table’s hash. The only time the operator works is when you’re using numerical indices for a dictionary, which is the equivalent of just making an array.

For example:

local library = {
    ["dict1"] = {"v1", "v2", "v3"}
}

#library will give 0, but #library.dict1 will give 3.
