How to send email attachments in PHP with Attachments

  • <?php // array with filenames to be sent as attachment $files = array("sendFiles.php"); // email fields: to, from, subject, and so on $to = "[email protected]"; $from = "[email protected]"; $subject ="My subject"; $message = "A logo has been sen't by". $_SESSION['loggedin_business_name']; $headers = "From: $from"; // boundary $semi_rand = md5(time()); $mime_boundary = "==Multipart_Boundary_x{$semi_rand}x"; // headers for attachment $headers .= "\nMIME-Version: 1.0\n" . "Content-Type: multipart/mixed;\n" . " boundary=\"{$mime_boundary}\""; // multipart boundary $message = "This is a multi-part message in MIME format.\n\n" . "--{$mime_boundary}\n" . "Content-Type: text/plain; charset=\"iso-8859-1\"\n" . "Content-Transfer-Encoding: 7bit\n\n" . $message . "\n\n"; $message .= "--{$mime_boundary}\n"; // preparing attachments for($x=0;$x<count($files);$x++){ $file = fopen($files[$x],"rb"); $data = fread($file,filesize($files[$x])); fclose($file); $data = chunk_split(base64_encode($data)); $message .= "Content-Type: {\"application/octet-stream\"};\n" . " name=\"$files[$x]\"\n" . "Content-Disposition: attachment;\n" . " filename=\"$files[$x]\"\n" . "Content-Transfer-Encoding: base64\n\n" . $data . "\n\n"; $message .= "--{$mime_boundary}\n"; } // send echo sizeof($files); $ok = @mail($to, $subject, $message, $headers); if ($ok) { echo "<p>mail sent to $to!</p>"; } else { echo "<p>mail could not be sent!</p>"; } ?> I get an email with my sendfiles.php then a text file ATT00424.txt. The number changes everytime. Send it to my gmail and it's fine! Very Strange! $files = array("sendFiles.php"); // email fields: to, from, subject, and so on $to = "[email protected]"; $from = "[email protected]"; $subject ="My subject"; $message = "A logo has been sen't by". $_POST['loggedin_business_name']; $headers = "From: $from"; // boundary $semi_rand = md5(time()); $mime_boundary = "==Multipart_Boundary_x{$semi_rand}x"; // headers for attachment $headers .= "\r\nMIME-Version: 1.0\r\n" . "Content-Type: multipart/mixed;\r\n" . " boundary=\"{$mime_boundary}\""; // multipart boundary $message = "This is a multi-part message in MIME format.\r\n" . "--{$mime_boundary}\r\n" . "Content-Type: text/plain; charset=\"iso-8859-1\"\r\n" . "Content-Transfer-Encoding: 7bit\r\n" . $message . "\r\n"; $message .= "--{$mime_boundary}\r\n"; // preparing attachments for($x=0;$x<count($files);$x++){ $file = fopen($files[$x],"rb"); $data = fread($file,filesize($files[$x])); fclose($file); $data = chunk_split(base64_encode($data)); $message .= "Content-Type: {\"application/octet-stream\"};\r\n" . " name=\"$files[$x]\"\r\n" . "Content-Disposition: attachment;\r\n" . " filename=\"$files[$x]\"\r\n" . "Content-Transfer-Encoding: base64\r\n" . $data . "\r\n"; $message .= "--{$mime_boundary}\r\n"; } Adding CRLF in the code fixed the attachment issue however now the message "A logo has been sen't by" has disappeared. Why is this?

  • Answer:

    Try having CRLF (\r\n) line breaks. Outlook can be a bit funny about these things.

Tareq

As I understand it, Outlook creates ATT12345.txt attachments when it receives messages in sections with mixed encoding. If it is unable to convert the remainder of the message after a change in encoding (or new MIME part), it dumps the rest in an attachment with the generic names you have been seeing. It seems as if Gmail is handling the format better than Outlook (unsurprising). I am no Outlook expert (never touch the thing), but it looks as if http://stackoverflow.com/questions/690430/attnnnnn-txt-attachments-when-e-mail-is-received-in-outlook might help (check your $mime_boundary variable for a trailling '--' after the last part).
