Problem in Client

[ednatmp]

Hi all, several weeks ago I was trying to solve a problem which i can not find solution. I've tried everything and nothing has worked. I need something to check if the user account is banner from the arena, and this code does not work ... Any help?
All the code is in client side.
 

The part of the function who call the checker:

if checkArenaBan(getAccountNamePlayer(_local), getElementID(arena.Element)) then
	addNotification("Usted está prohibido en esta arena.", "error")
	return
else
	etc
end

The checker:

function checkArenaBan(account, arena)
	local banlist = xmlLoadFile("arenas/acl/banlist.xml")
	for i, m in ipairs(xmlNodeGetChildren(banlist)) do
		if xmlNodeGetAttribute(m, "account") == account and xmlNodeGetAttribute(m, "arena") == arena then
			xmlUnloadFile(banlist)
			return true
		else
			xmlUnloadFile(banlist)
			return false
		end
	end
end

I think instead of _local you should put (source)

I defined _local

local _local = getLocalPlayer()

if everything is clientside it might be cheeky because players can edit xml files when it's added on clientside. this is prolly the source of the issue because you might be trying to reach a server xml file on clientside and it naturally cannot reach the file. try serverside

Oh right, thank you, but i have a question, how can i use a function from serverside to clientside with a return value, like true or false?

you'll use arguments, it's all well explained on wiki. takes some time to understand though.

it's like passing arguments to a function. pretty handy stuff really

here's an example for you:

 

--serverside

addEvent ("myEvent"); --add your event
addEventHandler ("myEvent", root, --and its handler
  	function (data) --argument of your data
		outputChatBox (tostring (data)); --execute
	end
);

--clientside

triggerServerEvent ("myEvent", resourceRoot, "My name is Jeff"); --this triggers "myEvent" event added on serverside and outputs "My name is Jeff" on serverside
