i have a question simular to this.... how can i get Slider data

PHP:

:
public function BuyForm($id, $player){
$api = $this->getServer()->getPluginManager()->getPlugin("FormAPI");
$form = $api->createCustomForm(function (Player $event, array $data){
$result = $data[1];
$player = $event->getPlayer();
});
$form->setTitle("Buy enchantment");

$form->sendToPlayer($player);
}

 

PHP:

if($result !== null){
   $item->addEnchantment(Enchantment::getEnchantment($id)->setLevel($result)
}


 

ty,

 

Maybe with foreach m'y code can work?

 

You must foreach players to get their name

 

Such as

PHP:

public function inviteSkyBlock(Player $player){
        $ui = new CustomForm("§lSkyBlock§r","§lInvite an Player!");
        foreach($this->getServer()->getOnlinePlayers() as $online){
            $name = $online->getName();
            $Dropdown = new Dropdown("§lInvite a player from the bolow liste:", array("§ln/a", $name));
        }
        var_dump($Dropdown);
        $ui->addElement($Dropdown);
        $pk = new ModalFormRequestPacket();
        $pk->formId = 111;
        $pk->formData = json_encode($ui);
        $player->dataPacket($pk);
        return true;
    }

 

Defined $dropdown before you do the foreach() to prevent getting error

 

Or try this to send multiple buttons as you want I think

PHP:

public function inviteSkyBlock(Player $player){
        $ui = new CustomForm("§lSkyBlock§r","§lInvite an Player!");
        $Dropdown = "";
        foreach($this->getServer()->getOnlinePlayers() as $online){
            $name = $online->getName();
            $Dropdown = new Dropdown("§lInvite a player from the bolow liste:", array("§ln/a", $name));
        var_dump($Dropdown);
        $ui->addElement($Dropdown);
        $pk = new ModalFormRequestPacket();
        $pk->formId = 111;
        $pk->formData = json_encode($ui);
        $player->dataPacket($pk);
        return true;
       }
    }

 

PHP:

public function inviteSkyBlock(Player $player){
        $ui = new CustomForm("§lSkyBlock§r","§lInvite an Player!");
        foreach($this->getServer()->getOnlinePlayers() as $online){
            $name = $online->getName();
            $Dropdown = new Dropdown("§lInvite a player from the bolow liste:", array($name));
        }
        $ui->addElement($Dropdown);
        $pk = new ModalFormRequestPacket();
        $pk->formId = 111;
        $pk->formData = json_encode($ui);
        $player->dataPacket($pk);
        return true;
    }


PHP:

public function DataPacketReceiveEvent(DataPacketReceiveEvent $event){
        $packet = $event->getPacket();
        $player = $event->getPlayer();
        if($packet instanceof ModalFormResponsePacket){
            $id = $packet->formId;
            $data = $packet->formData;
            $data = json_decode($data);
            if($data === Null) return true;
                if($id === 111){
                    if($data === 0){
                        //$this->getServer()->dispatchCommand($player, "sb invite" . $player->getName($data[0]));
                        $player->sendMessage("test");
                        return true;
                    }
                }
            }
        }
    }


Why nothing happen why ModalFormResponsePacket
(No error)

 

Same thing whith FromAPI nothing happen

PHP:

public function inviteSkyBlock($player){
        $api = $this->getServer()->getPluginManager()->getPlugin("FormAPI");
        $form = $api->createCustomForm(function (Player $event, array $data){
        $player = $event->getPlayer();
        $result = $data[0];
        if($result === null){
            $player->sendMessage("test");
        }
        switch($result){                           
            case 0:
            $player->sendMessage("test");
            break;
            case 1:
            $player->sendMessage("test");
            break;
            }                   
        });                   
        $form->setTitle("SkyBlock\ninvite");
        foreach($this->getServer()->getOnlinePlayers() as $online){
            $name = $online->getName();
            $form->addDropdown("§lInvite a player from the bolow liste:", array($name));
        }
        $form->sendToPlayer($player);
    }
