Answer 1

1) Rewrite Sales Class

Copy the file found at app\code\core\Mage\Sales\Model\Order.php to app\code\local\Mage\Sales\Model\Order.php Overwrite the sendNewOrderEmail() method found. Here you need to compose the attachment Copy the below code and paste it just before $mailer->send(); I am attaching a simple pdf file which is inside var/docs/abc.pdf

$dir = Mage::getBaseDir();
$file_name = $dir.DS.'var'.DS.'docs'.DS.'abc.pdf'; //file path
if(file_exists($file_name))
{
    $fileContents = file_get_contents($file_name);
    $fileName = 'abc.pdf';
    $mailer->addAttachment($fileContents, $fileName);
}

2) Rewrite mailer Copy the file found at app\code\core\Mage\Core\Model\Email\Template\Mailer.php to app\code\local\Mage\Core\Model\Email\Template\Mailer.php

Add a function and define a protected variable in class Mage_Core_Model_Email_Template_Mailer

protected $_afile = array(); 

public function addAttachment($fileContents,$fileName)
{
    $tmp = array();
    $tmp['fileContents'] = $fileContents;
    $tmp['fileName'] = $fileName;
    $this->_afile = $tmp;
    return $this;
}

Add code in send() method. In this method you will need to pass array of attachements Add below metioned lines just before $emailTemplate->setDesignConfig…

if(!empty($this->_afile))
{
    $emailTemplate->setEmAttachments($this->_afile); //(by dw)
}

3) Rewrite Template Copy the file found at app\code\core\Mage\Core\Model\Email\Template.php to app\code\local\Mage\Core\Model\Email\Template.php

Add below mentioned methods and define a protected variable

protected $_filedata = array(); 

public function setEmAttachments($attachments)
{
    $this->setOrderAttachments($attachments);
}

public function getEmAttachments()
{
    return $this->getOrderAttachments();
}

public function setOrderAttachments($attachments)
{   
    $this->_filedata = $attachments;        
    return $this;
}

public function getOrderAttachments()
{       
    return $this->_filedata;
}

Add below mentioned code in send() method just before $mail->send() as shown

$atInfo = $this->getEmAttachments();
if(!empty($atInfo))
{
    $_file = $mail->createAttachment($atInfo['fileContents']);
    $_file->type = 'application/pdf'; //the type should be as per your file
    $_file->filename = $atInfo['fileName'];
}

try {
    $mail->send();
    $this->_mail = null;
}
