PHP Email Attachment Function
Friday, June 20th, 2008Sending an email with PHP is pretty straight forwards. It's very useful for emailing reports generated from cron jobs etc.
Sometimes though you need your application to email an attachment.
After a load of messing around I have hacked together this email attachment PHP function.
PHP:
-
function email_attachment($to_email, $email, $subject,$our_email_name, $our_email, $file_location, $default_filetype='application/zip'){
-
$email = '<font face="arial">' . $email . '</font>';
-
$fileatt = $file_location;
-
$fileatttype = mime_content_type($file_location);
-
}else{
-
$fileatttype = $default_filetype;;
-
}
-
//prepare attachment
-
//create mime boundary
-
$mime_boundary = "==Multipart_Boundary_x{$semi_rand}x";
-
//create email section
-
$message = "This is a multi-part message in MIME format.\n\n" .
-
"--{$mime_boundary}\n" .
-
"Content-type: text/html; charset=us-ascii\n" .
-
"Content-Transfer-Encoding: 7bit\n\n" .
-
$email . "\n\n";
-
//create attachment section
-
$message .= "--{$mime_boundary}\n" .
-
"Content-Type: {$fileatttype};\n" .
-
" name=\"{$fileattname}\"\n" .
-
"Content-Disposition: attachment;\n" .
-
" filename=\"{$fileattname}\"\n" .
-
"Content-Transfer-Encoding: base64\n\n" .
-
$data . "\n\n" .
-
"--{$mime_boundary}--\n";
-
//headers
-
$domain = $exp[1];
-
$headers = "From: $our_email_name<$our_email>" . "\n";
-
$headers .= "Reply-To: $our_email"."\n";
-
$headers .= "Return-Path: $our_email" . "\n"; // these two to set reply address
-
$headers .= "X-Mailer: Edmonds Commerce Email Attachment Function"."\n"; // These two to help avoid spam-filters
-
$headers .= "MIME-Version: 1.0\n" .
-
"Content-Type: multipart/mixed;\n" .
-
" boundary=\"{$mime_boundary}\"";
-
-
}
The PHP and Email Journey Continues 
For a fully featured email attachment class this is definitely worth checking out. If you just want a quick function though without any bells and whistles then you should find my function will do the trick.
