php - Email Attachment and HTML Content Error

Question

I am writing an email attachment script in PHP. I have successfully done the image attachment to email but I am facing issues with the html.

Two Important thing in the Email:

1. Email Content which is HTML with some designs.

2. Email Attach Images.

If i use the following header I am able to see the Email with HTML designed. But attachment not working.

$headers .= "MIME-Version: 1.0\r\n";
$headers .= "Content-Type: text/html; charset=UTF-8\r\n";

If i use the following header I can able to attach the images successful. but the html is just coming as it is not showing how it was designed...

// 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"; 

Also this email should be shown perfectly in Outlook:

Can some one help to solve the issue.

Answer 1

The better way (easier and works fine) will be to use mailer class like PHPMailer...

But to answer you, you can find some help here.

You can find another helful example here

<!-- language: lang-php -->
// Prepare by setting a timezone, mail() uses this.
date_default_timezone_set('America/New_York');

// Save some values to send an email, these might have come from any source:
$to = 'example@eliw.com';
$subject = 'A sample email - Dual Format';

// Create a boundary string.  It needs to be unique (not in the text) so ...
// We are going to use the sha1 algorithm to generate a 40 character string:
$sep = sha1(date('r', time()));

// Define the headers we want passed.  Note that they are separated by \r\n
$headers = "From: php@example.com\r\nX-Mailer: Custom PHP Script";

// Add in our content boundary, and mime type specification:
$headers .=
    "\r\nContent-Type: multipart/alternative; boundary=\"PHP-alt-{$sep}\"";

// The body of the message.  Use the separator with -- in front of it to
//  mark the beginning of each section, and then provide the content type.
//  A blank line beneath that will define the beginning of the content.
//  At the end finish with the separator again, but this time with a --
//  after it as well.
$body =<<<EOBODY
--PHP-alt-{$sep}
Content-Type: text/plain

This is our sample email message

Hello World!

That's it for now

--PHP-alt-{$sep}
Content-Type: text/html

<p>This is our sample email message</p>
<h2>Hello World!</h2>
<p>That's it for now.</p>

--PHP-alt-{$sep}--
EOBODY;

// Finally, send the email
mail($to, $subject, $body, $headers);
