mgento2 自定义发送多个pdf附件的邮件

要在Magento2中发送多个PDF附件的邮件，您可以使用以下步骤：

1. 创建一个新的Magento模块（如果您尚未创建）。

2. 在您的模块中创建一个新的PHP文件，例如“EmailSender.php”，并编写以下代码：

<?php
namespace [YourNamespace]\[YourModule]\Helper;

use Magento\Framework\App\Filesystem\DirectoryList;
use Magento\Framework\Exception\MailException;
use Magento\Framework\Mail\Template\TransportBuilder;
use Magento\Framework\App\Helper\Context;
use Magento\Framework\App\Helper\AbstractHelper;
use Magento\Framework\Filesystem;

class EmailSender extends AbstractHelper
{
    protected $transportBuilder;
    protected $filesystem;
    protected $directoryList;

    public function __construct(
        Context $context,
        TransportBuilder $transportBuilder,
        Filesystem $filesystem,
        DirectoryList $directoryList
    ) {
        parent::__construct($context);
        $this->transportBuilder = $transportBuilder;
        $this->filesystem = $filesystem;
        $this->directoryList = $directoryList;
    }

    public function sendEmailWithAttachments($toEmail, $toName, $subject, $body, $attachments) {
        try {
            $transport = $this->transportBuilder
                ->setTemplateIdentifier('your_email_template_identifier')
                ->setTemplateOptions([
                    'area' => 'frontend',
                    'store' => \Magento\Store\Model\Store::DEFAULT_STORE_ID,
                ])
                ->setTemplateVars([
                    'subject' => $subject,
                    'body' => $body,
                ])
                ->setFrom([
                    'email' => 'your_email@example.com',
                    'name' => 'Your Name',
                ])
                ->addTo([
                    'email' => $toEmail,
                    'name' => $toName,
                ]);

            foreach ($attachments as $attachment) {
                $fileFullPath = $this->directoryList->getPath('var') . '/attachments/' . $attachment['file_name'];
                file_put_contents($fileFullPath, $attachment['file_content']);

                $transport->addAttachment(
                    file_get_contents($fileFullPath),
                    $attachment['file_name']
                );
            }

            $transport->getTransport()->sendMessage();
        } catch (MailException $e) {
            // Handle mail sending errors here
        }
    }
}

3. 在您的模块的“etc”文件夹中创建一个新的XML文件，例如“email_templates.xml”，并编写以下代码：

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Email:etc/email_templates.xsd">
    <template id="your_email_template_identifier" label="Your Email Template" file="your_email_template.html" type="html" module="[YourNamespace]_[YourModule]" area="frontend"/>
</config>

4. 在您的模块中创建一个新的HTML文件，例如“your_email_template.html”，并编写以下代码：

<!-- Your email template HTML code here -->
<h1>{{var subject}}</h1>
<p>{{var body}}</p>

5. 在您的代码中调用“EmailSender”帮助程序中的“sendEmailWithAttachments”方法，并传递电子邮件地址，主题，正文和附件数组作为参数。 例如：

$attachments = [
    [
        'file_name' => 'attachment1.pdf',
        'file_content' => file_get_contents('/path/to/attachment1.pdf'),
    ],
    [
        'file_name' => 'attachment2.pdf',
        'file_content' => file_get_contents('/path/to/attachment2.pdf'),
    ],
];

$this->emailSender->sendEmailWithAttachments(
    'recipient@example.com',
    'Recipient Name',
    'Email Subject',
    'Email Body',
    $attachments
);

请注意，此代码示例中的附件数组包含每个附件的文件名和内容。您可以根据需要更改此代码以满足您的需求。
