PHP Mailer send an mysql blob object - php

Question

I am storing a pdf or text file in mysql blob object, and I am trying to send that as a attachment in the mail using php mailer.
I am sending the mail like .
$mail->AddAddress($pr_email);
$mail->Subject = "Meeting Invitation -$meeting_name";
$mail->AddStringAttachment($data);
$mail->IsHTML(true);
$mail->Body =$message;
if(!$mail->Send())
{
$message= "Error sending: " . $mail->ErrorInfo;
header("Location:userprofile.php?Message={$message}");
}
Where $data came from
$tmpName = $_FILES['image']['tmp_name'];
$fp = fopen($tmpName, 'r');
$data = fread($fp, filesize($tmpName));
$data = addslashes($data);
fclose($fp);
$query = "UPDATE demo_meeting SET attachment='$data' where meetingID='$mtngid'";
$results = mysql_query($query);
Now I am receiving the mail as an attachment but content is not there, it is only showing 0K.
Please tell me what I might be doing wrong.

As I can see here in StackOverflow, you have ot pass additional parameters to AddStringAttachment: the mime type and the file name.
$filename="test.png";
$encoding = "base64";
$type = "image/png";
$mail->AddStringAttachment(base64_decode($data), $filename, $encoding, $type);
Also, NEVER use addslashes to "secure" a mysql field, you have to use mysql_real_escape_string instead (or, use PDO_MySQL driver which won't be marked obsolete anytime soon)
