图像和CSS未加载到Codeigniter电子邮件中

Question

我正在通过电子邮件发送html视图。电子邮件已成功发送，但是在接收到电子邮件后图像未加载且CSS未应用。 另外，我在整个HTML代码中遇到了错误。

错误

function send_mail() {
    $config = Array(
        'protocol' => 'smtp',
        'smtp_host' => 'demo.example.com',
        'smtp_port' => 465,
        'smtp_user' => 'my_smtp_username',
        'smtp_pass' => 'J@kO()FF%u]I',
        'mailtype' => 'html',
        'starttls' => true,
        'charset' => 'utf-8',
        'wordwrap' => TRUE,
        $config['newline'] = "\r\n",
        $config['crlf'] = "\r\n"
    );

    $message = '';
    $this->load->library('email', $config);
    $this->email->initialize($config);
    $this->email->set_newline("\r\n");
    $this->email->from('test@demo.example.com');
    $to_email = $this->input->post('email');
    $this->email->to($to_email); // change it to yours
    $mail_data = array(
        'username' => $to_email,
        'password' => random_string('alnum', 16)
    );
    $msg = $this->load->view('YMI/demo.php', $mail_data, true);
    $this->email->subject('Subject');
    $this->email->message($msg);
    if ($this->email->send()) {
        echo 'Email sent.';
    } else {
        show_error($this->email->print_debugger());
    }
    $this->load->view('YMI/admin/custEmail');
}

添加标题将帮助设置电子邮件的所需格式。 另外，如果您在现场加载视图，是否可以按预期完全加载？

 $this->load->library('email', $config);
        $this->email->set_newline("\r\n");
        $this->email->set_header('MIME-Version', '1.0; charset=utf-8');
        $this->email->set_header('Content-type', 'text/html');
