Magento 1.9 – Attach Invoice PDF in Invoice Email

emailinvoicemagento-1.9pdfzend-framework

I want to attach invoice pdf to the invoice mail, I followed the link and override the email functions.

First Override the app/code/Mage/core/Model/Email/Template/Mailer.php like,

  1. Adding protected $pdftemplate;

  2. Overriding the send() function,

    if($this->pdftemplate){
    $pdftemplate = $this->variable;
    }else{
    $pdftemplate = Mage::getModel('core/email_template');
    }

  3. Adding attachment function at the end of the class,

    /** Add Attachment**/

    public function addAttachment(Zend_Pdf $pdf, $filename){
    $file = $pdf->render();
    $this->pdftemplate = Mage::getModel('core/email_template'); 
    $attachment = $this->pdftemplate->getMail()->createAttachment($file);
    $attachment->type = 'application/pdf';
    $attachment->filename = $filename;
}

Second I override the app/code/Mage/Sales/Order/Invoice.php, sendEmail() function,

$mailer = Mage::getModel('core/email_template_mailer');
        $pdf = Mage::getModel('sales/order_pdf_invoice')->getPdf(array($this));
        $mailer->addAttachment($pdf,'invoice.pdf');

But the pdf is not attached. I don't know what to do next. I hope someone will point me the issue.

Thanks!..
