Thanks in Advanced.

Answer 1

First of all, Magento (at the time of writing, I am using Magento version 2.2.7) does not provide the functionality to add an attachment in the email.

To add an attachment programmatically in the email, first, you need to override \Magento\Framework\Mail\Template\TransportBuilder class.

Step 1: app/code/[Namespace]/[Module]/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">
    <preference for="\Magento\Framework\Mail\Template\TransportBuilder" type="\[Namespace]\[Module]\Mail\Template\TransportBuilder" />
</config>

Step 2: app/code/[Namespace]/[Module]/Mail/Template/TransportBuilder.php

<?php

namespace Stream\EmailPrintableCsv\Mail\Template;

class TransportBuilder extends \Magento\Framework\Mail\Template\TransportBuilder {

    public function addAttachment(
    $filePath, $filename = null, $mimeType = \Zend_Mime::TYPE_OCTETSTREAM, $disposition = \Zend_Mime::DISPOSITION_ATTACHMENT, $encoding = \Zend_Mime::ENCODING_BASE64
    ) {
        if (file_exists($filePath)) {
            $body = file_get_contents($filePath);
            $this->message->createAttachment($body, $mimeType, $disposition, $encoding, $filename);
        }
        return $this;
    }

}

Now, you can call addAttachment() function while sending an email.

Note: addAttachment function requires 2 parameters: filePath and fileName.

I wrote an extension to allow you to attach a file to the contact form

Take a look at the controller
