Solved Multiple world player count on Form

Yo! How to add the player count of two or more levels/worlds on Form(FormAPI)?

 

BUMP

 

PHP:

$level = Server->getLevelByName("name");
$var = count($firstLevel->getPlayers()) + count($secondLevel->getPlayers());
$form->addButton($var);


 

Does $firstLevel and $secondLevel mean this?

PHP:

$this->getServer()->getLevelByName("name");

 

Yes, use getLevelByName("here goes the name of the world");

 

Thank you
