Using Configs with consts

How could I add a configuration to a const? My current code is

PHP:

public const ERROR = $this->getConfig->get("error-message");


However it doesn't work. Prior to adding the config it was just:

PHP:

public const ERROR = "Error:";


What should I change for this to work?

 

You can't define class constants in runtime.

PHP:

public static $ERROR;

static::$ERROR = $this->getConfig()->get('error-message');


At that moment when constant is assigned with its value, $this variable is not even initialized. Therefore getting value out of Config object is not possible.

 

Hi!

PHP:

// Making it.
public const ERROR= $this->getConfig->get("error-message"); // You're trying to get plugin configuration, and in plugin configuration isn't the error


I remind you using this code:

PHP:

// Before start, you need to use Config class:

use pocketmine\utils\Config;

// This should be in "onEnable" function, replacing the another config

$this->getServer()->getPluginManager()->registerEvents($this, $this);
$this->database = new Config($this->getDataFolder() . "stats.yml", Config::YAML, array( 
    "last-error" = ""
));
$this->database;

// When an error happens, you use this code to set error
$this->database->set("last-error",  "Error Message Here");

// To get the error with a const, you use this:
public const ERROR= $this->database->get("last-error");


With this, in plugin_data folder you will see a file named stats.yml, when an error happens, you will se a change in the file and it should be like this:

Code:

---
last-error: "Last Error Message"
...

I hope this works for you, Thanks!

 

Yes, but your constant won't change values. And you can't redefine constants as they act like final static variables, for example
