Change FormAPI Button

Hi! Is it possible to change the button if player is op?

PHP:

public function openBattleForm($player){
    $api = $this->getServer()->getPluginManager()->getPlugin("FormAPI");
    $form = $api->createSimpleForm(function (Player $player, int $data = null) {
        $result = $data;
        if ($result === null) {
            return true;
        }
        switch ($result) {
            case 0;
                $player->sendMessage(" ");
                break;
            case 1;
                $player->sendMessage(" ");
                break;

        }

    });

    $form->setTitle("Test ");
    $form->setContent("Test");
    if($player->isOp()){ //$player is here unknown of course(This is my problem)

        $form->addButton("You are op! ");
    }else{

        $form->addButton("You are not op! ");
    }
    $form->addButton(" ");
    $form->sendToPlayer($player);
    return $form;

Is this even allowed in the API?

 

Why are you even trying to do that? Why don’t you just send a different form and have a check if the player is op beforehand???????????????????(x20)

And yes. Your method should work as well,

 

This is just an example. My originally purpose is way more laborius bc i have many Buttons etc. You have an idea where i could get the $player variable?

 

Player...variable....????????????????????????????

$player is already defined
