Hello Magento Friends,
In today’s blog we will learn about how to send email when there is a change in product prices for your Magento 2 store.
Keeping admins informed about product price changes can improve price management and foster transparency within your team. Here’s a comprehensive guide on how to set up this feature.
Before that, learn How to Change Product Price with Plugin in Magento 2.
Steps to Send Email when Product Price Change in Magento 2:
Step 1: First, we need to create an “events.xml“ file inside our extension at the following path
app\code\Vendor\Extension\etc\adminhtml\events.xml
Then add the below-mentioned code
<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Event/etc/events.xsd">
<event name="catalog_product_save_before">
<observer name="custom_shipping_observet" instance="Vendor\Extension\Observer\Saveshippingdata" />
</event>
</config>
Step 2: After that, we need to create a “Saveshippingdata.php” file inside our extension at the following path
app\code\Vendor\Extension\Observer\Saveshippingdata.php
And add the code as given below
<?php
namespace Vendor\Extension\Observer;
use \Magento\Framework\Event\Observer;
use \Magento\Framework\Event\ObserverInterface;
use Magento\ProductAlert\Model\StockFactory;
use Magento\Framework\App\ObjectManager;
use Magento\Framework\App\ResourceConnection;
use Magento\Customer\Model\CustomerFactory;
use Magento\Store\Model\StoreManagerInterface;
use Magento\Framework\Mail\Template\TransportBuilder;
use Magento\Framework\Translate\Inline\StateInterface;
use Magento\Directory\Model\Currency;
class Saveshippingdata implements ObserverInterface
{
protected $request;
protected $stockFactory;
protected $resourceConnection;
protected $customFactory;
protected $_transportBuilder;
protected $storeManager;
protected $inlineTranslation;
protected $currency;
public function __construct(
\Magento\Framework\App\RequestInterface $request,
StockFactory $stockFactory = null,
ResourceConnection $resourceConnection,
CustomerFactory $customFactory,
StoreManagerInterface $storeManager,
TransportBuilder $_transportBuilder,
StateInterface $inlineTranslation,
Currency $currency
)
{
$this->stockFactory = $stockFactory ?? ObjectManager::getInstance()->get(StockFactory::class);
$this->resourceConnection = $resourceConnection;
$this->request = $request;
$this->customFactory=$customFactory;
$this->storeManager=$storeManager;
$this->_transportBuilder=$_transportBuilder;
$this->inlineTranslation=$inlineTranslation;
$this->currency=$currency;
}
public function execute(Observer $observer)
{
$product = $observer->getEvent()->getDataObject();
$post = $this->request->getPost();
$post = $post['product'];
$originalPrice = $product->getOrigData('price');
$currentPrice = $product->getData('price');
if($originalPrice != '' && $originalPrice != NULL)
{
$formatted_original_price = number_format($originalPrice, 2);
if($formatted_original_price != $currentPrice)
{
if (array_key_exists("thumbnail",$post))
{
$product_image = $this->storeManager->getStore()->getBaseUrl(\Magento\Framework\UrlInterface::URL_TYPE_MEDIA).'catalog/product'.$post['thumbnail'];
}
$templateOptions = array('area' => \Magento\Framework\App\Area::AREA_FRONTEND, 'store' => $this->storeManager->getStore()->getId());
$templateVars = array(
'store' => $this->storeManager->getStore(),
'message' => 'Price change alert! We wanted you to know that prices have changed for these products:',
'productname'=>$post['name'],
'productimage'=>$product_image,
'producturl'=>$this->storeManager->getStore()->getBaseUrl().$post['url_key'].".html",
'productprice'=>$this->currency->format($post['price'], ['symbol' => $currencySymbol, 'precision'=> $precision], false, false)
);
$from = array('email' => "sender@example.com", 'name' => 'Sender Name');
$this->inlineTranslation->suspend();
$to = receiver@gmail.com;
$transport = $this->_transportBuilder->setTemplateIdentifier('price_change_email')
->setTemplateOptions($templateOptions)
->setTemplateVars($templateVars)
->setFrom($from)
->addTo($to)
->getTransport();
$transport->sendMessage();
$this->inlineTranslation->resume();
}
}
}
}
Step 3: After that, we need to create an “email_templates.xml” file inside our extension at the following path
app\code\Vendor\Extension\etc\adminhtml\email_templates.xml
And add the code as follows
<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Email:etc/email_templates.xsd">
<template id="price_change_email" label="Stock ALert" file="price_change.html" type="html" module="Vender_Extension" area="frontend"/>
</config>
Step 4: After that, we need to create a “price_change.html” file inside our extension at the following path
app\code\Vendor\Extension\view\frontend\email\price_change.html
Now add the below-mentioned code
<!--@subject Products price changed alert @-->
<!--@vars
{"store url=\"\"":"Store Url",
"skin url=\"email/logo/stores/1/Company_Logos_9_.png\" _area='frontend'":"Email Logo Image"}
@-->
<!--@styles
body,td { color:#2f2f2f; font:11px/1.35em Verdana, Arial, Helvetica, sans-serif; }
@-->
{{template config_path="design/email/header_template"}}
<table cellspacing="0" cellpadding="0" border="0" width="100%">
<tr>
<td align="center" valign="top" style="padding:20px 0 20px 0">
<table bgcolor="#FFFFFF" cellspacing="0" cellpadding="10" border="0" width="650" style="border:1px solid #E0E0E0;">
<tr>
<td valign="top">
<h1 style="font-size:22px;font-weight:normal;line-height:22px;margin:0 0 11px 0;">{{trans "Hello"}}</h1>
</td>
</tr>
<tr>
<td>
<table cellspacing="0" cellpadding="0" border="0" width="650">
<tbody>
<tr>
<td colspan="2" valign="top" style="font-size:12px;padding:7px 9px 9px 9px;border:1px solid #EAEAEA;">
{{var message}}
</td>
</tr>
<tr>
<td valign="top" style="font-size:12px;padding:7px 9px 9px 9px;border:1px solid #EAEAEA;">
<a href="{{var producturl}}">
<img src="{{var productimage}}" width="200px"
height="200px" alt="{{var productname}}">
<div class="product-name">{{trans "Product Name: "}}<b>{{var productname}}</b></div></a>
</td>
</tr>
<tr>
<td colspan="2" valign="top" style="font-size:12px;padding:7px 9px 9px 9px;border:1px solid #EAEAEA;">
{{trans "Price: "}}{{var productprice}}
</td>
</tr>
</tbody>
</table>
</td>
</tr>
<tr>
<td bgcolor="#EAEAEA" align="center" style="background:#EAEAEA;text-align:center;">
<center>
<p style="font-size:12px;margin:0;">
<strong>{{trans "Thank you"}}</strong>
</p>
</center>
</td>
</tr>
</table>
</td>
</tr>
</table>
{{template config_path="design/email/footer_template"}}
