Question

我有一个PDF格式，我是从Codeigniter中的html视图生成的，现在我想将它发送到我的电子邮件，但我遇到的麻烦是它显示$pdf中有一个字符串但是在我的电子邮件中发送时它是空的。这是整个Codeigniter功能。

public function generatePDF()
{
    require_once(APPPATH.'third_party/dompdf/dompdf_config.inc.php');

    $dompdf = new Dompdf();
    $msg = $this->load->view('credit_agreement_view', '', true);
    $html = mb_convert_encoding($msg, 'HTML-ENTITIES', 'UTF-8');
    $dompdf->load_html($html);
    $paper_orientation = 'Potrait';
    $dompdf->set_paper($paper_orientation);

    // Render the HTML as PDF
    $dompdf->render();
    $pdf = $dompdf->output();

    // sending the pdf to email
    $this->load->library('email');
    $config['protocol'] = 'smtp';
    $config['smtp_host'] = 'ssl://smtp.gmail.com';
    $config['smtp_port']    = '465';
    $config['smtp_timeout'] = '7';
    $config['smtp_user']    = 'support@aurorax.co';
    $config['smtp_pass']    = '#######';
    $config['charset']    = 'utf-8';
    $config['newline']    = "\r\n";
    $config['mailtype'] = 'text'; // or html
    $config['validation'] = TRUE; // bool whether to validate email or not    
    $this->email->initialize($config);

    $this->email->from('support@aurorax.co', 'aurora exchange');
    $this->email->to('masnad@aurorax.co');
    $this->email->subject('pdf');
    $this->email->attach($pdf);
    $this->email->message('Hello!');  

    $this->email->send();
}

您的代码帮助我实现了发送pdf附件而不将其保存在服务器上。我没有调用渲染方法。

    //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"
    }

要实际发送附件，您必须生成pdf文件，而不仅仅是在浏览器中将其作为pdf呈现。添加$dompdf->render();行后 $dompdf->stream("attachment.pdf"); 并附加使用此附件文件的绝对路径。发送电子邮件后，您始终可以取消链接（删除）附件。

使用codeigniter通过电子邮件发送由dompdf生成的pdf
