How to made an Config that changes the join and leave messages

I need your help, i will an config file that changes the join and leave messages
-GeistFan

 

What do you exactly need?

 

I would like to know how I do this

 

PHP:

// Your file
$this->config= new Config($this->getDataFolder() . "config.yml" , Config::YAML);
$this->config->get("message");


Code:

---
# Config file
message: "This is the message that it will send"

Is this what you want?

 

I want that config

Code:

# JoinLeave
join: "message"
leave: "message"

 

PHP:

public function onJoin(PlayerJoinEvent $event){
    $event->setJoinMessage($this->getConfig()->get("join"));
}


PHP:

public function onKick(PlayerKickEvent $event){
    $event->setQuitMessage($this->getConfig()->get("leave"));
}


also remember to register events

 

Now I have this problem:

I used this tutorial:
https://forums.pmmp.io/threads/using-configs.1975/

 

PHP:

         /** @var string[] */
         private $config;
         public function onEnable() : void {
                  $this->config = $this->getConfig()->getAll(); // ??????????????????????????????????????????????????????????
         }
}


+ @mkdir($this->getDataFolder()); isn't necessary !
