Trying to get file to attach to email message from upload form

wolfsta · May 4, 2012

Hi all

I have a script that I have patched together and got to work in pieces. I'm up to the last part. I have the form working and emailing. It also will upload an image by itself and put it in a folder. Now i just need to tie those together and have the image put in the email as an attachment then deleted from server.

I have it at a stage where it sends me the users details.. and it tries to send the photo but it comes through as junk txt. I think its the MIME encoding stuff that I have wrong.. not sure?

Here's what I have so far.

$attachment = $path_of_uploaded_file;
$fileatt = $attachment; // Path to the file                  
$fileatt_type = "application/octet-stream"; // File Type 
    $start=	strrpos($attachment, '/') == -1 ? strrpos($attachment, '//') : strrpos($attachment, '/')+1;
$fileatt_name = substr($attachment, $start, strlen($attachment)); // Filename that will be used for the file as the attachment 

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

$semi_rand = md5(time()); 
$mime_boundary = "==Multipart_Boundary_x{$semi_rand}x"; 
$headers = "\nMIME-Version: 1.0\n" . 
            "Content-Type: multipart/mixed;\n" . 
            " boundary=\"{$mime_boundary}\""; 

$email_message .= "This is a multi-part message in MIME format.\n\n" . 
                "--{$mime_boundary}\n" . 
                "Content-Type:text/html; charset=\"iso-8859-1\"\n" . 
               "Content-Transfer-Encoding: 7bit\n\n" . 

 $data = chunk_split(base64_encode($data)); 
$email_message .= "--{$mime_boundary}\n" . 
                  "Content-Type: {$fileatt_type};\n" . 
                  " name=\"{$fileatt_name}\"\n" . 
                  "Content-Disposition: attachment;\n" . 
                  " filename=\"{$fileatt_name}\"\n" . 
                  "Content-Transfer-Encoding: base64\n\n" .
                 $data . "\n\n" . 
                  "--{$mime_boundary}--\n";
     
// create email headers
$headers .= 'From: '.$email_from."\r\n".
'Reply-To: '.$email_from."\r\n" .
'X-Mailer: PHP/' . phpversion();

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

Thanks

Entire php if you need to look at it. I know its probably quite messy or better ways to do it but I'm a novice, ill tidy up as I go and learn:

Any one know how to do this? or have a simpler way of attaching file? I tried using getimagesize() to return the MIME type but it gave me txt html for a jpg??

I just had to do this earlier today. This is what worked for me. This works for multiple files.

Awesome thanks Mike, I'll see if I can tie it into mine.

wolfsta · May 5, 2012

Mike I tried to use your script but I cant get it to work at all. I deleted all my code and just used yours and added my email address to the variable $to and it doesn't work. Changed the name= in my html form to uploadedFiles... I get the email but no attachment at all

Any suggestions?

Ok so ended up going back to my code.. As it seemed to be closer.. with the help of a friend realized the MIME encoding stuff wasn't quite right.

Here is the fixed working code just have to add multiple file support now:

   $attachment = $path_of_uploaded_file;
$fileatt = $attachment; // Path to the file                  
$fileatt_type = "application/octet-stream"; // File Type 
    $start=	strrpos($attachment, '/') == -1 ? strrpos($attachment, '//') : strrpos($attachment, '/')+1;
$fileatt_name = substr($attachment, $start, strlen($attachment)); // Filename that will be used for the file as the attachment 

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

$semi_rand = md5(time()); 
$mime_boundary = "==Multipart_Boundary_x{$semi_rand}x"; 
$headers = "MIME-Version: 1.0\n" . 
            "Content-Type: multipart/mixed;\n" . 
            " boundary=\"{$mime_boundary}\""; 

$email_message = "This is a multi-part message in MIME format.\n\n" . 
                "--{$mime_boundary}\n" . 
                "Content-Type:text/html; charset=\"iso-8859-1\"\n" . 
               "Content-Transfer-Encoding: 7bit\n\n" . 
		   
$email_message .= "Form details below:"."<br>"."<br>";		   
$email_message .= "First Name:"."\t".clean_string($first_name). "<br>";
    $email_message .= "Last Name:"."\t".clean_string($last_name)."<br>";
$email_message .= "Age:"."\t".clean_string($age)."<br>";
$email_message .= "Height:"."\t".clean_string($height_feet).'ft ' . clean_string($height_inches).'in'."<br>";
$email_message .= "City:"."\t".clean_string($city)."<br>";
$email_message .= "State:"."\t".clean_string($state)."<br>";
    $email_message .= "Email:"."\t".clean_string($email_from)."<br>";
    $email_message .= "Telephone:"."\t".clean_string($telephone)."<br>";
    $email_message .= "Comments:"."\t".clean_string($comments)."<br>"."<br>"."\n";

 $data = chunk_split(base64_encode($data)); 
$email_message .= "--{$mime_boundary}\n" . 
                  "Content-Type: {$fileatt_type};\n" . 
                  " name=\"{$fileatt_name}\"\n" . 
                  "Content-Disposition: attachment;\n" . 
                  " filename=\"{$fileatt_name}\"\n" . 
                  "Content-Transfer-Encoding: base64\n\n" .
                 $data . "\n\n" . 
                  "--{$mime_boundary}--\n";
     
// create email headers
$headers .= "\n" . 'From: '.$email_from."\r\n".
'Reply-To: '.$email_from."\r\n" .
'X-Mailer: PHP/' . phpversion();

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