Block Events??

I am making a plugin and I need some help...
Is there a piece of code that can detect if someone places a specific block?

BlockPlaceEvent, if the block($e->getBlock()->getId()) is the block(Block::whatever) (or use instanceof without getId()), then do something

Are you still there??
can you make a piece of code that detected a user who places down TNT, then
kicks them???

Sorry i am VERY NEW to plugin development i made my first plugin 2 days ago..

PHP:

public function onBlockPlace(BlockPlaceEvent $e){
        if ($block->getBlock()->getId(46)) {getPlayer(Player::kick)
    }
}

For reason add

PHP:

( $reason = "Do not place TNT!")


What is this? Java?

What. The...

I am going to run this I'll be back with the testing results. P.S i am making a AntiGreafing plugin

What I've got so far:

PHP:

<?php

namespace dc4code\cfxs;

use pocketmine\plugin\PluginBase;
use pocketmine\command\Command;
use pocketmine\command\CommandSender;
use pocketmine\command\ConsoleCommandSender;
use pocketmine\event\block\BlockPlaceEvent;
use pocketmine\Player;


class cfxs extends PluginBase {

    public function onEnable(){
    $this->getLogger()->info("HelpME Enabled");
        return true;
    }
  

    public function onLoad(){
        $this->getLogger()->info("HelpME Loaded Properly.");
    }
  

    public function onCommand(CommandSender $sender, Command $command, $label, array $args){
        switch($command->getName()){
            case "cfxsv":
                if($sender instanceof Player){
                    $sender->sendMessage("CFX Security Software Version 1.0.2 Build Register. #112SGND");
                    return true;
                }

                else{
                    $sender->sendMessage("This command only works in-game.");
            }
        }
    }   


public function onBlockPlace(BlockPlaceEvent $e){
        if ($block->getBlock()->getId(46)) {getPlayer(Player::kick)
            $ExecuteAction = "say " + $player + " Tried to place a block of TNT!";
            $this->getServer()->dispatchCommand(new ConsoleCommandSender(),$ExecuteAction);
            
    }
}
  
    public function onDisable(){
        $this->getLogger()->info("HelpME Disabled.");
        return true;
    }
}

1. You can use [ PHP ] [/ PHP ] tags.

2. You don't need return true; in the onDisable and onEnable functions.

3. Dispatching Commands is bad practice, maybe try something like:

PHP:

$this->getServer()->broadcastMessage("Message!");


It should be

PHP:

$ExecuteAction = 'say ' . $e->getPlayer() . ' tried to place a block of TNT!';


Remember, this is PHP, not Java (or other)

Do NOT use whatever codes @Survingo says, they are severely incorrect. That's why you're getting errors.

Also, this would still crash because you're echoing a Player object, it should be:

PHP:

$ExecuteAction = 'say ' . $e->getPlayer()->getName() . ' tried to place a block of TNT!';


I completely forgot about that

No worries

So... can I have a piece of code that detected if the player placed TNT, then
Deopps them
Puts them in Game mode Survival
Warns the console
Then kicks the person who placed TNT?

Why don't you just block TNT? And: What if they aren't OP and what if they are in Survival Mode? Then that wouldn't make sense

he makes a valid point...

You Guys don't understand..... this is so i can learn PHP i dont really care of the other methods out there. I'm just trying to make a plugin. Thats it.
