(PrestaShop) 从核心类调用静态方法的正确方法

Question

核心文件之一 classes/stock/StockAvailable.php包含：class StockAvailableCore extends ObjectModel{   public static function getQuantityAvailableByProduct($id_product = null, $id_product_attribute = null, $id_shop = null)     {       ...     }  ...}我想从我的模块中调用这个 getQuantityAvailableByProduct()方法。所以我尝试包含这个类（它是父类和父类的接口），扩展它并像这样调用方法：require_once('../../src/Core/Foundation/Database/EntityInterface.php');require_once('../../classes/ObjectModel.php');require_once('../../classes/stock/StockAvailable.php');$MyClass = new StockAvailableCore();$MyClass->getStockAvailableIdByProductId($id);而我得到的错误：PHP Fatal error:  Uncaught Error: Class 'ObjectModel' not found in /home/mantas/Server/honey/classes/stock/StockAvailable.php:34我错过了什么？这是扩展类和调用方法的正确方法吗？

ObjectModel.php 文件

<?php

    class ObjectModel{

        //For example I created non-static function in ObjectModel class

        public function getStockAvailableIdByProductId($id){

            return "test";

        }

        //For example I created static function in ObjectModel class

        public static function getStockAvailableIdByProductIdStatic($id){

            return "teststatic";

        }

    }

   ?>

StockAvailable.php 文件。

<?php

//Extends used to inherit the parent class property

    class StockAvailableCore extends ObjectModel

    {

       public static function getQuantityAvailableByProduct($id_product = null, $id_product_attribute = null, $id_shop = null)

         {

         }

    }

    ?>

运行.php文件

<?php

require_once('ObjectModel.php');

require_once('StockAvailable.php');

$MyClass = new StockAvailableCore();

// Access the ObjectModel function

//to access the  Non-static method need to create the object.

echo $MyClass->getStockAvailableIdByProductId($id);

//Static method access by class reference (::)

echo StockAvailableCore::getStockAvailableIdByProductIdStatic($id);

?>
