Attach file in formmail. (php formmail)

I'm writing a mailform i php for placeing orders, and sense they have to get send a picture to me for the order to work properly, I'd like to be able to attach the file in the formmail. How shuld I do this? I have seen some different sulutions but non that I've complety understand.

From stackoverflow

• You need to set the right mail-headers, and then attach the file by encoding it to whatever form you have declared in the header, like in this snippet:

  All you need to do here, is read the file, and encode it (to base64 in this case)

  $file = fopen($fileatt,'rb');
  $data = fread($file,filesize($fileatt));
  fclose($file);
  
  $data = chunk_split(base64_encode($data));
  

  first you'll need a boundary, like a rule to tell where one part stops, and the other begins

  $semi_rand = md5(time());
  $mime_boundary = "==Multipart_Boundary_x{$semi_rand}x";
  

  then set the headers right, to support attachement

  $headers .= "\nMIME-Version: 1.0\n" .
  "Content-Type: multipart/mixed;\n" .
  " boundary=\"{$mime_boundary}\"";
  

  then build up your message

  $email_message .= "This is a multi-part message in MIME format.\n\n" .
  "--{$mime_boundary}\n" . // start text block
  "Content-Type:text/html; charset=\"iso-8859-1\"\n" .
  "Content-Transfer-Encoding: 7bit\n\n" .
  $email_content . "\n\n" .
  "--{$mime_boundary}\n" . // start attachement
  "Content-Type: {$fileatt_type};\n" .
  " name=\"{$fileatt_name}\"\n" .
  //"Content-Disposition: attachment;\n" .
  //" filename=\"{$fileatt_name}\"\n" .
  "Content-Transfer-Encoding: base64\n\n" .
  $data . "\n\n" . // this is the file...
  "--{$mime_boundary}\n";
  

  and then... sent the message using mail ;-)

  mail($email_to, $email_subject, $email_message, $headers)
  

• I would also suggest php_mailer http://sourceforge.net/project/showfiles.php?group_id=26031

  Has all of the options you could ever want and lets you build custom length forms without "TOO" much pain

  There are also a bunch of tutorials and would gladly send along an example of a project I did recently if you want

• $sl="select max(id)AS maxid from photos"; $res=mysql_query($sl); $rowl=@mysql_fetch_array($res);

  $adid=$rowl['maxid']; $filedir="/photo_gallery/"; $file1=$filedir."img".$adid.$_FILES['myfile']['name'];

  //echo $file1; @move_uploaded_file($_FILES['myfile']['tmp_name'],$file1);

  $upd="update photos set photo='".$file1."',Added_date=now() where id=$adid";

  //echo $upd; mysql_query($upd);

  @unlink($file1);
