Evite Script to Send HTML Email

I would like to have a form on my website where a user can enter their friends email address and name, then click send, and it would send an html email to the friend (an evite).

Is there a script or anything out there for this? I’ve looked but can’t find much. My php is a little limited.

I’ve been using this script, but it sends emails in plain text. Is there a way to cahnge it to html?

//Put your website name between the quotes below:
$websiteName = "My Website";

//Put your website address between the quotes below:
$websiteAddress = "www.domain.org/evite.html";


// If you have a privacy policy, put in the link title: 
$privacyPolicyLinkText = "";


// Put in the "" the url to you your privacy policy, if you have one,
$privacyPolicyLinkURL = "";


// Change the 0 to a 1 below, 
//if you want to recieve a notice when people are refered:
$notice = 1;


//Put your email address in the " " if you changed the notice to 1
$adminEmail = "test@domain.com";


//Put the subject line text you want the email to read in the  "":
$subject = "You have been invited to...";

// Put your default message intro text in the first set of quotes below
//This is what the people who are referred will see
//along with any personal message entered by the referer.
$defaultMessageIntro = "<div style="background:#555555;">Join me at...!</div> " . "

//Put in the "" your default close (this will be at the end of the message):
$defaultMessageClose = "____________________________________________________________________

CUSTOM MESSAGE GOES HERE";
