Question

The following $header is being sent via PHP s mail($to,$subject,$content,$header) command. The mail arrives and appears to have an attachment. But the mail text is empty as is the file. I think this has something to do with line spacing but I can t see the problem. I have tried putting the contents (between the boundaries) in $contents rather than appending it to $header. It doesn t make a difference. Any thoughts?

$header ends without a line break

Answer 1

I use the code below to send a message with an attachment as well as html and text message parts. I remember fighting with it a long time to get it right, but unfortunately don t remember which parts were my problems. Maybe looking at it will help you out. I ve changed some irrelevant variables and hopefully made it easier to read. Feel free to ask if something is weird or unclear and I ll try to explain.

public function sendEmail($htmlString)
{
    $random_hash = md5(date( r , time()));

    $message = "--mixed-$random_hash
";
    $message .=  Content-Type: multipart/alternative; boundary="alt-  . $random_hash .  "  . "

";
    $message .=  MIME-Version: 1.0  . "
";
    $message .=  --alt-  . $random_hash . "
";
    $message .=  Content-Type: text/plain; charset="iso-8859-1"  . "
";
    $message .=  Content-Transfer-Encoding: 7bit  . "

";

    // text message
    $message .= strip_tags($htmlString) . "

";

    $message .=  --alt-  . $random_hash . "
";
    $message .=  Content-Type: text/html; charset="iso-8859-1"  . "
";
    $message .=  Content-Transfer-Encoding: 7bit  . "

";

    // html message
    $message .= $htmlString . "

";

    $message .=  --alt-  . $random_hash .  --  . "
";

    // graph image
    if($this->selectedGraph != 0)
    {
        $graphString = $this->getGraph(); // image attachment
        $graphString = chunk_split(base64_encode($graphString));

        $linkID =  graph-  . $userInfo[ FirmID ] . $random_hash .  -image ;

        $message .=  --mixed-  . $random_hash . "
";
        $message .=  MIME-Version: 1.0  . "
";
        $message .=  Content-Transfer-Encoding: base64  . "
";
        $message .=  Content-ID:   . $linkID . "
";
        $message .=  Content-Type: image/gif; name="graph.gif"  . "
";
        $message .=  Content-Disposition: attachment  . "

";

        $message .= $graphString;
        $message .=  --mixed-  . $random_hash .  --  . "
";

    }
    else
    {
        $message .=  --mixed-  . $random_hash .  --  . "
";
    }


    $headers =  From:   . $this->from. "
Reply-To: " . $this->replyto;
    $headers .= "
Content-Type: multipart/related; boundary="mixed-" . $random_hash . ""
MIME-Version: 1.0";

    $flags =  -f   . BOUNCED_EMAIL_ADDRESS;

    return mail($userInfo[ Email ], $this->subject, $message, $headers, $flags);

}

These things happen when building mime mails from scratch. There are a couple of php modules you can use to generate cool and compatible mime messages. Mail_Mime should do the trick.
