I also had a very hard time sending HTML-formatted email as multipart.
Following are some code samples from what eventually worked for me. I think
you can have lots of variations in the headers without problems, and that
your main problem is how you're using the boundary. VERY IMPORTANT: Note how
I'm adding "--" before the boundary when it's used to separate things, and
how the last use of the boundary is followed by another "--".
// define a boundary strings to use in multipart email
$OB = "----=_OuterBoundary_000";
// set multipart/alternative headers
$multiheaders = "From: $from_name<$from_email>\n";
if ($reply_to_email != "") {
$multiheaders .= "Reply-To: " . $reply_to_name . "<" .
$reply_to_email . ">\n";
}
$multiheaders .= "Return-Path: <$from_email>\n";
$multiheaders .= "X-Mailer: PHP4\n";
$multiheaders .= "MIME-Version: 1.0\n";
$multiheaders .= "Content-Type: multipart/alternative;\n\tboundary=\"" . $OB
. "\"\n\n";
$multiheaders .= "--" . $OB . "\n";
$multiheaders .= "Content-Type: text/plain; charset=us-ascii\n";
$multiheaders .= "Content-Transfer-Encoding: 7bit\n";
$multiheaders .= "Content-Disposition: inline\n\n";
My code samples are all chopped up because they're part of a queuing system.
I create a plain text message and an HTML-formatted message and write
everything to a MySQL database. A separate script that's called by a crontab
actually sends the email. (That let's me control frequency and volume.)
After pulling from the database, I build the multipart message from the
plain text message, the boundary, some more specific headers, the
HTML-formatted message.
// build multipart/alternative
$multipart_message = $message . "\n\n--" . $boundary . "\n" .
"Content-Type: text/html; charset=us-ascii" . "\n" . "Content-Disposition:
inline" . "\n\n" .
html_entity_decode($html_message) . "\n\n--" . $boundary .
"--\n\n--End--\n\n\n";
if ([EMAIL PROTECTED]("$fullname<$email>", $subject, $multipart_message,
$multiheaders)) {
// some stuff for error checking
}
Hopefully you can decipher my example.
