Call new packet problem

Why the chest window do not popup when i call that with a command ?

public function commandHandler($cmd, $params, $issuer, $alias){
switch($cmd){
case "openchest":
$player = $issuer;
$this->openEnderchest = true;
//console(FORMAT_GREEN."Chest Open".FORMAT_RESET);
$player->windowCnt++;
$player->windowCnt = $id = max(2, $player->windowCnt % 99);
$player->windows[$id] = TILE_CHEST;
$pk = new ContainerOpenPacket;
$pk->windowid = $id;
$pk->type = WINDOW_CHEST;
$pk->slots = is_array($player->windows[$id]) ? CHEST_SLOTS << 1:CHEST_SLOTS;
$pk->x = 0;
$pk->y = 0;
$pk->z = 0;
$player->dataPacket($pk);
break;
}
}

But if I can disable the opening of a chest, its because I can order to open it too ?

bah if you code a simple handle like that, you can disable the opening of the window chest

PHP:

    public function eventHandle($data, $event) {
        switch ($event) {
            case "player.block.touch":
                if($data["target"]->getID() == 54) return false;
            break;
        }
     }

why i cant open a window chest without chest ?

Ok this time I understand what you mean !! Well, i can send the pakect anytime but the client ll not process it because it didnt ask for it !! So im sad that i cant do that ;(
