Emailing pdf generated by dompdf with codeigniter

Your code helped me implement sending pdf attachments without saving them on server. I wasn't calling the render method.

    //load dompdf library    $this->load->library('PHPPdf');    $objPHPPdf = new PHPPdf();    $objPHPPdf->loadHtml($attachment, 'UTF-8');    // (Optional) Setup the paper size and orientation    $objPHPPdf->setPaper('A4', 'portrait');    // Render the HTML as PDF    $objPHPPdf->render();    $pdf = $objPHPPdf->output();    $this->load->library('email');    $this->email->initialize($this->config->item("email_config"));    $from = $this->config->item("email_from");    $this->email->from($from["from"], $from["from_name"]);    $this->email->to($to);    $this->email->subject('Sample');    $this->email->message('Sample message');    $this->email->attach($pdf, 'application/pdf', "Pdf File " . date("m-d H-i-s") . ".pdf", false);    $r = $this->email->send();    if (!$r) {        // "Failed to send email:" . $this->email->print_debugger(array("header")));    } else {        // "Email sent"    }

To actually send an attachment you have to generate the pdf file not just render it in browser as pdf. After $dompdf->render(); line add $dompdf->stream("attachment.pdf"); and while attaching use the absolute path of this attachment file. you can always unlink(delete) the attachment after sending the email.
