I have all configurable products on my website and I want to add the extra charges (after some calculation and conditions) to product price by overriding method or anything else which follow the Magento standard.

I have follow the following scenario:

I have tried this by using plugin method. It override the configurable product price only not it’s child. Also not working properly on product list page.

1.etc/di.xml

<?xml version="1.0"?> <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd"> <type name="Magento\Catalog\Model\Product">     <plugin name="product_price_change"             type="Namespace\Modulename\Plugin\Updateprice"             sortOrder="1"/> </type> </config> 

2.Plugin/Updateprice.php

<?php namespace Namespace\Modulename\Plugin;  class Updateprice {     /**      *  \Namespace\Modulename\Helper\Data $  helper      *      * @var Namespace\Modulename\Helper\Data      */     protected $  _helper;      protected $  _configurable;      protected $  product;      public function __construct(         \Namespace\Modulename\Helper\Data $  helper,         \Magento\ConfigurableProduct\Model\ResourceModel\Product\Type\Configurable $  configurable,         \Magento\Catalog\Model\Product $  product     ) {         $  this->_helper = $  helper;         $  this->_configurable = $  configurable;         $  this->_product = $  product;     }      public function afterGetPrice(\Magento\Catalog\Model\Product $  subject, $  result) {         if($  subject->getTypeId() == "configurable"){             return $  result + $  this->_helper->getAdditionalPrice($  subject);         }else{             return $  result + $  this->_helper->chkAdditionalPrice($  subject);         }     } } 

getAdditionalPrice function is defined in helper which have some calculation and return additional price according to product attribute otherwise it returns false;

I have also tried catalog_product_get_final_price magento event. This is working fine for “Simple Product” not for the associated simple product (configurable simple product).

I want to carry configurable product price to cart and checkout.

Any suggestion would be appreciated.

Thanks
