Codeigniter 中的 HTML 格式的电子邮件

如何在 codeigniter 中发送格式化的电子邮件？我有这段代码，可以很好地发送电子邮件，但它没有按应有的方式格式化它。您可以看到显示收到电子邮件的图片：

function email_sender()
        {
            //      $this->load->helper('form');
            // $this->load->helper('url');
            $config = Array(
                    'protocol' => 'sendmail',
                    'smtp_host' => 'ssl://smtp.gmail.com',
                    'smtp_port' => '465',
                    'smtp_timeout' => '7',
                    'smtp_user' => '****@****.com',
                    'smtp_pass' => '*******',
                    'charset' =>'utf-8',
                    'newline' => "\r\n",
                    'MIME-Version' => '1.0',
                    'mailtype' => 'html',
                    'header' => 'MIME-Version: 1.0',
                    'header' => 'Content-type:text/html;charset=UTF-8'
                );//initializing mail headers and information
            if ($this->input->post('submit')==true) 
            {
            $data['name']=$this->input->post('contact-name');
            $data['email']=$this->input->post('contact-email');
            $data['phone']=$this->input->post('contact-tel');
            $data['country']=$this->input->post('contact-country');
            $data['message']=$this->input->post('exampleTextarea');
            }//input from form
            $html_formattedEmail = $this->load->view('includes/email_template', $data, TRUE);//variable that loads view and save it as string
            $this->load->library('email', $config);
            // $this->email-> set_newline("\r\n");
            $this->email->from('[email protected] /cdn-cgi/l/email-protection');
            $this->email->to($data['email']);
            $this->email->subject('Contact form submitted');
            $this->email->message($html_formattedEmail);
    
            if($this->email->send()){
                $data['main_content'] = 'thankyou_page';
                 $data['meta_title'] = 'abc';
                    $data['meta_description'] = 'abc2';
                     $data['meta_author'] = 'abc3';
            $this->load->view('includes/template', $data);
    
            }
            else{
                show_error($this->email->print_debugger());
            }
        }

Try this

// load email library
$this->load->library('email');

// 准备电子邮件

$this->email
    ->from('[email protected] /cdn-cgi/l/email-protection', 'Example Test.')
    ->to('[email protected] /cdn-cgi/l/email-protection')
    ->subject('Hello Sample Test.')
    ->message('Hello, We are <strong>Htl content</strong>')
    ->set_mailtype('html');

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

您还可以使用视图文件

$this->email
    ->from('[email protected] /cdn-cgi/l/email-protection', 'Example Test.')
    ->to('[email protected] /cdn-cgi/l/email-protection')
    ->subject('Hello Sample Test.')
    ->message($this->load->view('email_template-name', $dynamic-data, true))
    ->set_mailtype('html');
