Getting/placing block with custom name

Hey does anyone know how to get a block which a custom name example a chest which has a custom name called "hai" and when placing it it sends a message but if it's a normal chest it doesn't do anything. I want it to be on the function BlockBreakEvent.

 

Can you please show proof of a previous attempt?

PHP:

Public function onPlace (Blockplaceevent  $ev){
  $player = $ev->getPlayer();
  $hand = $player->getInventory()->getItemInHand();
  If($hand->getId() == 54){
    If ($hand->getCustomName() === "hai"){
        $player->sendMessage("hai");
        }
    
    }
}

 

PHP:

Public function onPlace (Blockplaceevent  $ev) {
    $hand = $ev->getPlayer()->getInventory()->getItemInHand();
    if($hand->getId() === Block::CHEST and $hand->getName() === "hai") {
        $player->sendMessage("hai");
    }
}

 

How would I remove that block I placed?

 

With setBlock()

 

Ik it's set block but doesn't work

 

You doing something wrong then

 

When do you want the block placed to be removed?
