Join Server Commands

Hello, in a code like this one below I would like to execute a command at each join of the server mcpe, how could I integrate in a code like its?

PHP:

<?php

namespace jblusdev\kenchycore;

use pocketmine\event\Listener;
use pocketmine\event\player\PlayerLoginEvent;
use pocketmine\plugin\PluginBase as Plugin;

use CustomAlerts\Commands\Commands;
use CustomAlerts\Events\CustomAlertsMotdUpdateEvent;

class Loader extends Plugin implements Listener{
    public function onEnable(){
        $this->getServer()->getPluginManager()->registerEvents($this, $this);
        $this->getServer()->getLogger()->info("KenchyCore Enabled!");
    }

    public function onPlayerLogin(PlayerLoginEvent $event){
        $event->getPlayer()->teleport($this->getServer()->getDefaultLevel()->getSafeSpawn());
    }

}

 

dispatchCommand is probably your friend here

What are you trying to do with the command? This might be a case of http://xyproblem.info

 

It depends who you want to execute the command, if its the player joining it would be

PHP:

$this->getServer()->dispatchCommand($event->getPlayer(), "command");


If you want the executor to be console it would be

PHP:

$this->getServer()->dispatchCommand(new \pocketmine\command\ConsoleCommandSender, "cmd");


 

PHP:

<?php

namespace jblusdev\kenchycore;

use pocketmine\event\Listener;
use pocketmine\event\player\PlayerLoginEvent;
use pocketmine\plugin\PluginBase as Plugin;

use CustomAlerts\Commands\Commands;
use CustomAlerts\Events\CustomAlertsMotdUpdateEvent;

class Loader extends Plugin implements Listener{
    public function onEnable(){
        $this->getServer()->getPluginManager()->registerEvents($this, $this);
        $this->getServer()->getLogger()->info("KenchyCore Enabled!");
    }

    public function onPlayerLogin(PlayerLoginEvent $event){
        $event->getPlayer()->teleport($this->getServer()->getDefaultLevel()->getSafeSpawn());
        $this->getServer()->dispatchCommand($event->getPlayer(), "rules");
    }

}

So once the line of code you told me to put my code will look like this:

 

Yes, also I would recommend using PlayerJoinEvent as it gets called when the player gets onto the server instead of PlayerLoginEvent which is called before the player is on the server
