Proper way to call static method from core class

[mantas393]

Hi,

One of the core files classes/stock/StockAvailable.php contains:

class StockAvailableCore extends ObjectModel
{
    public static function getQuantityAvailableByProduct($id_product = null, $id_product_attribute = null, $id_shop = null)
    {
		...
	}
	...
}

 

I want to call this getQuantityAvailableByProduct()  method from my module.

So I tried to include this class, extend it and call method like this:

<?php

require_once('../../src/Core/Foundation/Database/EntityInterface.php');
require_once('../../classes/ObjectModel.php');
require_once('../../classes/stock/StockAvailable.php');

$MyClass = new StockAvailableCore();

$MyClass->getStockAvailableIdByProductId($id);

 

And the error that I'm getting:

PHP Fatal error:  Uncaught Error: Class 'ObjectModel' not found in /home/mantas/Server/honey/classes/stock/StockAvailable.php:34

What am i missing? And Is this the correct way to extend a class and call method?

Hi...

$getQuantityAvailableByProduct = StockAvailable::getQuantityAvailableByProduct($id_product = null, $id_product_attribute = null, $id_shop = null)
