email attachment - UNIX vs Windows (IIS)

davebarnes

I have a form which works on a Linix/Apache/PHP server and does not on a Windows/IIS/PHP server.

This form (UNIX-based PHP) works correctly:
http://www.marketingtactics.com/PHP_Tutorials/PHP_RequestInfo_Primer/Lessons/Lesson_32/Lesson32_EmailAttach.php

When you complete the form, a valid email and a READABLE attachment are sent to me.

This form (Windows-based PHP) does not work correctly:
http://www.alamedaeast.com/PHP_Tutorials/PHP_RequestInfo_Primer/Lessons/Lesson_32/Lesson32_EmailAttach.php

I receive the email and what appears to be a valid attachment. However, the attachment can not be opened with the application (e.g., MS Word) or the attachment can be opened, but it is garbled (e.g., a HTML file).

The code is identical on both sites.
Below is what I think is the relevant code:

	
... 
  $fp = fopen($newUploadedFilePath,"rb"); 
  $myAttachment = fread($fp,filesize($newUploadedFilePath)); 
  $myAttachment = chunk_split(base64_encode($myAttachment)); 
  fclose($fp); 
... 
  $messageToAcme .= "--" .$mimeBoundary. "\n"; 
  $messageToAcme .= "Content-Type: " .$uploadedFileType ."; name=\"" .$newUploadedFileName ."\"\n"; 
  $messageToAcme .= "Content-Transfer-Encoding: base64\n"; 
  $messageToAcme .= "Content-Disposition: attachment\n"; 
  $messageToAcme .= "\n";            /*  This line MUST be here or it won't work  */ 
  $messageToAcme .= $myAttachment; 
  $messageToAcme .= "--" .$mimeBoundary ."--\n"; 
... 
  mail($recipientAcme, "Please Send Acme Info", $messageToAcme, $mailAcmeHeaders)

( Complete source code available at http://www.alamedaeast.com/PHP_Tutorials/PHP_RequestInfo_Primer/Lessons/Lesson_32/Lesson32_EmailAttach.phps )

So, what do I do to fix this?

thanks,

I assume you've tried "\r\n" on the affected script?

davebarnes

I did not think of using \r\n in place of \n.

Thanks for the good suggestion. I did it and NOTHING CHANGED.
I still get the exact same behavior.

So, now my suspect code appears as:

...
  $messageToAcme .= "--" .$mimeBoundary. "\r\n";
  $messageToAcme .= "Content-Type: " .$uploadedFileType ."; name=\"" .$newUploadedFileName ."\"\r\n"; 
  $messageToAcme .= "Content-Transfer-Encoding: base64\r\n"; 
  $messageToAcme .= "Content-Disposition: attachment\r\n";
  $messageToAcme .= "\r\n";            /*  This line MUST be here or it won't work  */
  $messageToAcme .= $myAttachment;
  $messageToAcme .= "--" .$mimeBoundary ."--\r\n";

So, I am ready for the next idea.

Any chance your server is confused about MIME types?

Reason I ask, have you tried clicking the link to your PHP source that you posted above?
