I want to send eamil notification to main admin, for modification avail in price by any admin.

Please help,

Thank You in advance.


You should use the around plugin for your requirement. around plugin should be used on afterSave($object) method of \Magento\Catalog\Model\Product\Attribute\Backend\Price class.

This class has been assigned as backend_model to product prices attributes so when product prices will be updated this backend_model class will be called.

So below given code will be useful to you to send the email when value of price attribute will be changed.

FILE: Kartik\PriceUpdate\etc\adminhtml\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\Attribute\Backend\Price">
        <plugin name="send_email_when_price_change" type="Kartik\PriceUpdate\Plugin\Product\Attribute\Backend\PricePlugin"/>

FILE: Kartik\PriceUpdate\Plugin\Product\Attribute\Backend\PricePlugin.php

namespace Kartik\PriceUpdate\Plugin\Product\Attribute\Backend;

class PricePlugin
    const PRICE_ATTRIBUTE = 'price';

     * @param \Magento\Catalog\Model\Product\Attribute\Backend\Price $subject
     * @param callable $proceed
     * @param $object
     * @return mixed
    public function aroundAfterSave(\Magento\Catalog\Model\Product\Attribute\Backend\Price $subject, callable $proceed, $object)
        $result = $proceed($object);
        $attributeCode = $subject->getAttribute()->getAttributeCode();

        if ($attributeCode == self::PRICE_ATTRIBUTE) {
            if ($object->hasData($attributeCode)) {
                $originalData = $object->getOrigData($attributeCode);
                $newData = $object->getData($attributeCode);

                if ($originalData !== $newData) {
                    // implement your email logic here
        return $result;

Plugin is always better option while implementing this type of requirement. If plugin is not helpful then only you should move to different solution.

  • Great. You can vote for the same. Thanks. Jul 25 '19 at 5:10

You should be able to hook in to the catalog_product_save_after event to create an observer, & look at $observer->getProduct()->getData() to see the new data. You can compare a specific number of fields (eg: price, special_price) by checking getData() vs getOrigData()

There's a more complete answer here which should hold up for Magento 2.3.

  • Thank you, This is also work properly.
