在 magento 2 中将产品添加到购物车后如何发送电子邮件？

Question

不幸的是，到目前为止，我完全是一个在 magento 中创建模块的初学者。我需要在将商品添加到购物车后发送电子邮件。

据我了解，我需要使用checkout_cart_product_add_after事件

我创建了一些文件，但我不知道如何在将商品添加到购物车后发送电子邮件

My/Module/etc/events.xml

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Event/etc/events.xsd">
<event name="checkout_cart_product_add_after">
    <observer name="email_after_adding_product" instance="My\Module\Observer\SendEmailForCart"/>
</event>

My/Module/Observer/SendEmailForCart.php

<?php
namespace My\Module\Observer;

use Magento\Framework\Event\ObserverInterface;
use My\Module\Helper\Email;

class SendEmailForCart implements ObserverInterface
{
    private $helperEmail;

    public function __construct(
        Email $helperEmail
    ) {
        $this->helperEmail = $helperEmail;
    }
    public function execute(\Magento\Framework\Event\Observer $observer)
    {
        return $this->helperEmail->sendEmail();
    }
}

My/Module/Helper/Email.php

<?php

namespace My\Module\Helper;

class Email extends \Magento\Framework\App\Helper\AbstractHelper
{

    public function __construct(

    )
    {

    }

    public function sendEmail()
    {
        try {
            
        } catch (\Exception $e) {

        }
    }
}

请问，我需要在Email.php文件中写什么代码？我是否需要创建任何其他文件或修改上面显示的文件？

Answer 1

在 vendor/magento 中自行研究。发送电子邮件的地方很多。寻找 $transport 或 $transport 对象变量（不记得了）

/**
* Recipient email config path

const XML_PATH_EMAIL_RECIPIENT = 'contact/email/recipient_email';
/**

public function __construct(

    parent::__construct($context);
    $this->_transportBuilder = $transportBuilder;
    $this->inlineTranslation = $inlineTranslation;
    $this->scopeConfig = $scopeConfig;
    $this->storeManager = $storeManager;
    $this->_escaper = $escaper;

/**

public function execute()

    $post = $this->getRequest()->getPostValue();
    if (!$post) {
        $this->_redirect('*/*/');
        return;
    }

    $this->inlineTranslation->suspend();

    try {
        $postObject = new \Magento\Framework\DataObject();
        $postObject->setData($post);
        $error = false;

        $sender = [
            'name' => $this->_escaper->escapeHtml($post['name']),
            'email' => $this->_escaper->escapeHtml($post['email']),
        ];

        $storeScope = \Magento\Store\Model\ScopeInterface::SCOPE_STORE; 
        $transport = $this->_transportBuilder
            ->setTemplateIdentifier('send_email_email_template') // this code we have mentioned in the email_templates.xml
            ->setTemplateOptions(
                [
                    'area' => \Magento\Framework\App\Area::AREA_FRONTEND, // this is using frontend area to get the template file
                    'store' => \Magento\Store\Model\Store::DEFAULT_STORE_ID,
                ]
            )
            ->setTemplateVars(['data' => $postObject])
            ->setFrom($sender)
            ->addTo($this->scopeConfig->getValue(self::XML_PATH_EMAIL_RECIPIENT, $storeScope))
            ->getTransport();

            $transport->sendMessage();
            $this->inlineTranslation->resume();
            $this->messageManager->addSuccess(
                __('Thanks for contacting us with your comments and questions. We\'ll respond to you very soon.')
            );
            $this->_redirect('*/*/');
            return;
    } catch (\Exception $e) {
        $this->inlineTranslation->resume();
        $this->messageManager->addError(__('We can\'t process your request right now. Sorry, that\'s all we know.'.$e->getMessage())
        );
        $this->_redirect('*/*/');
        return;
    }
}
