[HELP] Login system

[Sande]

Hello, i´m trying to make a login system for my server. But because i am beginner on these login i can not complete it. I have been search many info from wiki and forums how to make the functions and the login function working already. Register functions works too but there is some little problems like you can register while you have empty boxes etc. I dont have any idea how to check that things and the code are so messed up. If someone can fix my code i will be happy.

I can pay something for the fixer when i get money to my paypal.

!But the "remember me" functions should work then.

Server-side:

  
function loginHandler(username,password) 
    -- check that the username and password are correct 
    local account = getAccount ( username, password ) 
            if ( account ~= false ) then 
                logIn(source, account, password) 
        -- the player has successfully logged in, so spawn them 
        if (client) then 
            spawnPlayer(client, 1959.55, -1714.46, 10) 
            fadeCamera(client, true) 
                        setCameraTarget(client, client) 
            outputChatBox("Welcome to My Server.", client) 
        end 
    else 
        -- if the username or password are not correct, output a message to the player 
        outputChatBox("Invalid username and password. Please try again.",client) 
        triggerClientEvent (source,"openLogin",getRootElement()) 
        end          
end 
  
addEvent("submitLogin",true) 
addEventHandler("submitLogin",root,loginHandler) 
  
function register (username,password, passwordC) 
local account = getAccount (username,password) 
                    if (account == false) then 
                        local accountAdded = addAccount(tostring(username),tostring(password)) 
                        if (accountAdded) then 
                            outputChatBox ("#FF0000* #00FF00You have sucessfuly registered! [username: #FFFFFF" .. username .. " #00FF00| Password: #FFFFFF" .. password .. "#00FF00 ]",source,255,255,255,true ) 
                              logIn(source, account, password) 
                              if (client) then 
            spawnPlayer(client, 1959.55, -1714.46, 10) 
            fadeCamera(client, true) 
                        setCameraTarget(client, client) 
            outputChatBox("Welcome to My Server.", client) 
                        else 
                        outputChatBox("Error while registering new account!", source, 255,0,0) 
                        triggerClientEvent (source,"openLogin",getRootElement()) 
                        end 
                        end 
                        end 
                        end 
                        addEvent("submitRegister",true) 
                        addEventHandler("submitRegister",root,register) 
  

Client-side

Supposing your saving/loading system functions are right (didnt checked them) and the rest itself is ok, this should work:

(I also did some small tweaks, like you werent checking the terms checkbox, nor filling back the edit boxes on panel creation)
