Problem with config

Look at my code I want add player name to config when join arena, it do not add anything....

PHP:

public function getPlayers($arena){
    $config = new Config($this->getDataFolder()."Arenas/".$arena.".yml", Config::YAML);

    $playersXXX = $config->get("Players");

    $players = array();

    foreach ($playersXXX as $x){
        if($x != "steve steve"){
            $players[] = $x;
        }
    }

    return $players;


public function addPlayerToArena($arena, $name){

    $config = new Config($this->getDataFolder()."Arenas/".$arena.".yml", Config::YAML);

    $players = $this->getPlayers($arena);

    $players[] = $name;

    $config->set("Players", $players);
    $config->save();
}


}

When player join i use addPlayerToArena function

 

I can't find an error here, allthough creating configs on each call is much overhead. Are you sure you call addPlayerToArena?

 

Yes I adding player to arena.. When i change for example $config->set("Players", $players); to $config->set("Players", "test");
It is working

 

Try define the default value of the YAML file an array.
Then when you want to access the config, use the following code:

PHP:

$v = $this->config->getAll();
foreach($players as $name){
    $v["players"][] = $name;
}
$this->config->setAll($v);
$this->config->save();

($v could be anything e.g. $c or $tmp or $cfg, just define the variable yourself)

 

In my Jail plugin, I mainly use this method to store players' data so you could look into it for reference.
