Login

[Charlie_Jefferson]

Hai, I'm tryina' make a login system. No idea how to say that if username and password are in a .xml file, then login. This is the code cut into a piece. I've got the usern and passw defined and they are added when registered. Or should be. Didn't test it yet.

function login( thePlayer, command, username, password ) 
  
    load = xmlLoadFile ( "accl.xml" ) 
        child = xmlFindChild ( group, "user", 0 ) 
         
            if (usern and passw == load)    then 
                menu 
            else 
                label[2] = guiCreateLabel(insertcoordshere, "Please type a correct username/password!") 
                    setTimer(label[2], 5000, 3) 
            end 
end 

And this is the whole code:

showCursor(true) 
fadeCamera(true) 
setCameraMatrix(insertCityHall/PDcoordshere) 
user = guiCreateEdit(insertcoordshere) 
pass = guiCreateEdit(insertcoordshere) 
register = guiCreateButton(insertcoordshere) 
login = guiCreateButton(insertcoordshere) 
addEventHandler( "onClientGUIClick", register, register ) 
addEventHandler( "onClientGUIClick", login, login ) 
  
  
function register() 
     
     
    local usern = guiGetText( user ) 
    local passw = guiGetText( pass ) 
        if (username>3 or password>3)   then 
            label[1] =  guiCreateLalbel(insertcoordshere, "Please write a longer username/password!") 
                setTimer(label[1], 5000, 3) 
    else 
        xmlLoad = xmlLoadFile ( "accl.xml" ) 
    end 
        if xmlRootTree  then 
            xmlNodeSetValue ( "user", usern, passw ) 
        else 
            return 
        end 
end 
  
function login( thePlayer, command, username, password ) 
  
    load = xmlLoadFile ( "accl.xml" ) 
        child = xmlFindChild ( group, "user", 0 ) 
         
            if (usern and passw == load)    then 
                menu 
            else 
                label[2] = guiCreateLabel(insertcoordshere,"Please type a correct username/password!") 
                    setTimer(label[2], 5000, 3) 
            end 
end 
         
         
     
  
     

Note: where it's written "insertcoordshere" or anything to do with that, it means I will write the coordinates later.

What ?? why are you loading acl.xml ?

[Charlie_Jefferson]

So it can get the username and password from it and check if they exist.

[mjau]

Well thats not needed acl.xml is acces control list wich means eaxample supermoderator, admin , etc

[Charlie_Jefferson]

Then where do I store them and how do I get them? >.>

[mjau]

You want to get the account info so you can read it ?

[Charlie_Jefferson]

I want to store them, with the register button and check if they are true and if they are, then login the player with the login button.

[Castillo]

kimmis, you didn't get what he's trying to do.

If I'm right, he's trying to save and load the account details from a CLIENT SIDE XML fiel called "acl.xml", but that doesn't mean is the access control list.

[Charlie_Jefferson]

Well, yeah.

[mjau]

Oh ok ...

EDIT: Why do you need that ?

[Charlie_Jefferson]

... I need the accl.xml so I can store usernames and passwords and so that the player can login. Are you making fun of me?

[Castillo]

No, I guess he's just trying to increase the post count, or he's just stupid.

[mjau]

What im not trying to increase my stupid post count ... and im not making fun of you but for a normal login panel you dont need a xml file to store them ...

[Castillo]

He's trying to save the USERNAME and PASSWORD so when he joins again, he doesn't have to type it AGAIN AND AGAIN.

What you say makes no sense.

[mjau]

Thanks castillo now i understand XDD i see what i said made no sense now sorry for it...

But idk what the probelm is here im a bit to tired now since i dont understand a shit

[Charlie_Jefferson]

Actually this is my basic login GUI. What you do is write your username and password on the GUI edits, click register, which saves your username and account into my account list(accl.xml) and then, you login. I'm trying to make it search the username and password, when you input something into the edits and click login and if the username and password exist, then it logs you in. THAT'S ALL. And I'm stuck on ONE BIT of problem. How do I make the script search the accl.xml. If you can help me with that, you are so helpful and you will be the most epic person in the world.

Sorry for exaggerating, I just want my script to work ;P.

[Charlie_Jefferson]

Also, for some reason, the camera matrix setting and the fade camera and the show cursor don't work. I did add source, true and the coords needed to them, but they just won't work.

[mjau]

Ah ok well i never worked with more advanced xml than one node so i think u should wait for someone else than me to answer

[Charlie_Jefferson]

Okay...

[Castillo]

function saveLoginToXML(username, password) 
    xmlFile = xmlLoadFile ("userdata.xml") 
    if not xmlFile then 
        xmlFile = xmlCreateFile("userdata.xml", "login") 
    end 
    local usernameNode = xmlFindChild (xmlFile, "username", 0) 
    local passwordNode = xmlFindChild (xmlFile, "password", 0) 
    local success = xmlNodeSetValue (usernameNode, tostring(username)) 
    local success2 = xmlNodeSetValue (passwordNode, tostring(password)) 
    if success and success2 then 
        xmlSaveFile(xmlFile) 
    end 
    xmlUnloadFile (xmlFile) 
end 
  
function loadLoginFromXML() 
    xmlFile = xmlLoadFile ("userdata.xml") 
    if not xmlFile then 
        xmlFile = xmlCreateFile("userdata.xml", "login") 
    end 
        local usernameNode = xmlFindChild (xmlFile, "username", 0) 
        local passwordNode = xmlFindChild (xmlFile, "password", 0) 
        if usernameNode and passwordNode then 
            return xmlNodeGetValue(usernameNode), xmlNodeGetValue(passwordNode) 
        else 
            return "", "" 
    end 
    xmlUnloadFile (xmlFile) 
end 

[Charlie_Jefferson]

Right. Now... How do I make it so that the player logins, when he clicks on a login button which I'll create? The loadlogin thing should be the login function. And if the username and password are entered correctly, the player should login into his account and some other GUI, which I'll make later will be shown and he can select and do stuff. No point in going further. Just help.

[Castillo]

These two functions should be used like this:

On login button clicked -> saveLoginToXML(username, password)

When player joins(onClientResourceStart) -> loadLoginFromXML() which returns two values (username and password).

[Charlie_Jefferson]

Then how does the register button help? I think that the register button should be saveToXML and login would be the loadFromXML.

[Castillo]

Now I'm lost, what are you trying to achieve? I don't understand.

[Charlie_Jefferson]

I'll say it clearly: this IS a login system made by me. I'm trying to make the "Register" and "Login" buttons work. I made a GUI which has two edit boxes: Username and Password. You write your username and password in those two boxes and press register. The register button send the username and password to the .xml file, which stores them. I need to make it so that if the username and password are in the .xml file, you can login. That's ALL.
