How do I use FormAPI?

Correct Code

PHP:

if($command->getName() == "infoui") {
if(!$sender instanceof Player){
$sender->sendMessage("§cThis works only in-game");
return true;
}
if($this->getConfig()->get("enabled") === false){
$sender->sendMessage("§cThis feature is disabled");
return true;
}
$form = $this->getServer()->getPluginManager()->getPlugin("FormAPI")->createSimpleForm(function (Player $sender,  $data) {
switch($data) {
case 0:
$sender->sendMessage("Working!");
break;
}
});
$form->setTitle("Server Info");
$form->setContent($this->getConfig()->get("text"));
$form->addButton("OK!");
$form->sendToPlayer($sender);
}

 

Yes it works, thank you!

 

Btw, what was the problem?

 

you can see source, but befor please learn PHP (in you dont know ) also you can add files in to your own plugin or depend it in your plugin.
