Another little help with FormAPI

I was trying to make a dropdown and select a player then i type a message in the input and the player i chose get the message.
My attempt:

PHP:

<?php

namespace ddui\Command;

use pocketmine\Player;
use jojoe77777\FormAPI;
use pocketmine\command\{
    Command,
    CommandSender
};
use pocketmine\command\PluginCommand;
use ddui\DropdownUI;

class DropdownCMD extends PluginCommand {
   
    public function __construct($command, DropdownUI $plugin){
        parent::__construct($command, $plugin);
    }
   
    public function execute(CommandSender $sender, string $commandLabel, array $args){
        $api = $this->getPlugin()->getServer()->getPluginManager()->getPlugin("FormAPI");
        if($api === null){
            return true;
        }
        $form = $api->createCustomForm(function(Player $sender, array $data){
            if(data[0] != null){
                $cmd = "tell ".$data[0]."  ".$data[1];
                $this->getPlugin()->getServer()->getCommandMap()->dispatch($sender, $cmd);
                return true;
            }
        });
        $form->setTitle("TestDropdown");
        $form->addDropdown("Dropdown", $this->getPlugin()->getServer()->getOnlinePlayers());
        $form->addInput("Message");
        $form->sendToPlayer($sender);
    }
}
?>


The Plugin Works Fine but the player doesnt get the message.

 

And i got the error from the console:

You must foreach getOnlinePlayers();

 

Done but doesnt work again

 

Didnt you see the error in the console?

 

It sasys that $data isnt defined but it is defiened

 

Check your code again

PHP:

if(data[0] != null){


After you, wath wrong here?

 

The $ fixed but not working again ._.

 

Not working? plz explain more

 

I chose the player i want and wrote the message but the player doesnt get the message.

 

Try that

PHP:

public function execute(CommandSender $sender, string $commandLabel, array $args){
        $api = $this->getPlugin()->getServer()->getPluginManager()->getPlugin("FormAPI");
        if($api === null){
            return true;
        }
        $form = $api->createCustomForm(function (Player $sender, array $data){
        $result = $data[0];
        if($result != null){
            $sender->sendMessage("data is null");
        }
        switch($result){
            case 0:
            break;
            case 1:
            break;
        }
        });
        foreach ($this->getServer()->getOnlinePlayers() as $value){
            $nametag = $value->getName();
        }
        $form->setTitle("");
        $form->addDropdown("Player Liste:", [$nametag]);
        $form->sendToPlayer($sender); 
    }

 

You did not put an input

 

Where is the input? xd

 

That will only provide the username of the last player, as you are changing $nametag in your foreach() statement each time.

 

You could add each name to an array in your foreach statement or you could use the array_map function.

Example 1

PHP:

$names = [];
foreach ($this->getPlugin()->getServer()->getOnlinePlayers() as $player) {
    $names[] = $player->getName();
}


Example 2

PHP:

$names = array_map(function ($player) {
    return $player->getName();
}, $this->getPlugin()->getServer()->getOnlinePlayers());

 

I'l try it thx
