Is it possible to have HTML emails in osTicket?

I have an e-mail开发者_如何学C template that I use to send out account emails and I'd like to use the same HTML email template via osTicket.. is this possible?

Modifications in class.ticket.php

1. Add this new function

   function getHtmlEmailTemplate(){ return $this->config['html_email_template']; }

2. add this line to $sql var at UpdatePref() function...

   ',spoof_default_smtp='.db_input(($var['default_smtp_id'] && isset($var['spoof_default_smtp']))?1:0).

Modifications in class.email.php

1. Replace your Send() function by this one:

function send($to,$subject,$message,$attachment=null) {
        global $cfg;

        //Get SMTP info IF enabled!
        $smtp=array();
        if($this->isSMTPEnabled() && ($info=$this->getSMTPInfo())){ 
            $smtp=$info;
        }elseif($cfg && ($email=$cfg->getDefaultSMTPEmail()) && $email->isSMTPEnabled()){ //What about global SMTP setting?
            if($cfg->allowSMTPSpoofing() && ($info=$email->getSMTPInfo())){ 
                $smtp=$info;
            }elseif($email->getId()!=$this->getId()){
                return $email->send($to,$subject,$message,$attachment);
            }
        }

        //Get the goodies
        require_once ('Mail.php'); // PEAR Mail package
        require_once ('Mail/mime.php'); // PEAR Mail_Mime packge

        //do some cleanup
        $eol="\n";
        $to=preg_replace("/(\r\n|\r|\n)/s",'', trim($to));
        $subject=stripslashes(preg_replace("/(\r\n|\r|\n)/s",'', trim($subject)));
        $body = stripslashes(preg_replace("/(\r\n|\r)/s", "\n", trim($message)));
        $htmlbody = str_replace('%message', str_replace("\n", '<br />', $body), $cfg->getHtmlEmailTemplate());
        $fromname=$this->getName();
        $from =sprintf('"%s"<%s>',($fromname?$fromname:$this->getEmail()),$this->getEmail());
        $headers = array ('From' => $from,
                          'To' => $to,
                          'Subject' => $subject,

                          );
        $mime = new Mail_mime();
        $mime->setTXTBody($body);
        if (strpos($cfg->getHtmlEmailTemplate(), '%message') !== false) 
          $mime->setHTMLBody($htmlbody);
        //attachment TODO: allow multiple attachments - $attachment should be mixed parts.
        if($attachment && $attachment['file'] && is_readable($attachment['file'])) { 
            $mime->addAttachment($attachment['file'],$attachment['type'],$attachment['name']);
        }
        $options=array('head_encoding' => 'quoted-printable',

                       'text_charset'  => 'utf-8');
        //encode the body
        $body = $mime->get($options);
        //encode the headers.
        $headers = $mime->headers($headers);
        if($smtp){ //Send via SMTP
            $mail = mail::factory('smtp',
                    array ('host' => $smtp['host'],
                           'port' => $smtp['port'],
                           'auth' => $smtp['auth']?true:false,
                           'username' => $smtp['username'],
                           'password' => $smtp['password'],
                           'timeout'  =>20,
                           'debug' => false,
                           ));
            $result = $mail->send($to, $headers, $body);
            if(!PEAR::isError($result))
                return true;

            $alert=sprintf("Unable to email via %s:%d [%s]\n\n%s\n",$smtp['host'],$smtp['port'],$smtp['username'],$result->getMessage());
            Sys::log(LOG_ALERT,'SMTP Error',$alert,false);
            //print_r($result);
        }

        //No SMTP or it failed....use php's native mail function.
        $mail = mail::factory('mail');
        return PEAR::isError($mail->send($to, $headers, $body))?false:true;

    }

2.- Replace your sendmail() function by this one:

function sendmail($to,$subject,$message,$from) {

        require_once ('Mail.php'); // PEAR Mail package
        require_once ('Mail/mime.php'); // PEAR Mail_Mime packge

        $eol="\n";
        $to=preg_replace("/(\r\n|\r|\n)/s",'', trim($to));
        $subject=stripslashes(preg_replace("/(\r\n|\r|\n)/s",'', trim($subject)));
        $body = stripslashes(preg_replace("/(\r\n|\r)/s", "\n", trim($message)));
        $htmlbody = str_replace('%message', str_replace("\n", '<br />', $body), $cfg->getHtmlEmailTemplate()); 
        $headers = array ('From' =>$from,
                          'To' => $to,
                          'Subject' => $subject,
                          'Message-ID' =>'<'.Misc::randCode(10).''.time().'@osTicket>',
                          'X-Mailer' =>'osTicket v 1.6',
                          'Content-Type' => 'text/html; charset="UTF-8"'
                          );
        $mime = new Mail_mime();
        $mime->setTXTBody($body);

          $mime->setHTMLBody($htmlbody);
        $options=array('head_encoding' => 'quoted-printable',

        $mail = mail::factory('mail');
        return PEAR::isError($mail->send($to, $headers, $body))?false:true;
    }

Modifications in preference.inc.php

1.- Add this HTML code where you want inside the table

<tr><th>HTML Email Template:</th>
          <td><textarea rows="15" name="html_email_template" style="width:600px;"><?=$config['html_email_template']?></textarea><br><i>Will be used for all outgoing emails.<br />Insert %message where you want the message text to be replaced in the template.</i></td>
        </tr>

Finally you have got a TextArea at Preferences/Settings page which allow you to write your own HTML code for the template. Just type %message where you want to place the message into the template :)

It looks like you might be out of luck. Take a look at this forum post from osTicket. HTML is stripped from the email before sending.
