PHP 'send to friend' form to email script with multipart text/HTML content

Hi

I'm putting together a website and I need a 'send to a friend' form to enable people to forward campaign details on by email. I have no experience with PHP. I know there is a recent version of PHP on the Linux server hosting the site but there are no extras included with my hosting options so I need something that uses the in-built PHP mail function.

Perhaps I'm being too ambitious here but ideally I want a basic HTML form which collects the name/email of the sender/recipient, and then sends a formatted multipart email to the recipient and a blind copy to me. Ideally the email needs to be personalised with the name.

In ASP I'd usually do this by passing the name as a query string to a formatted HTML page, incorporating a second text page, and sending both as a multipart using ASPEmail.

The HTML part is not a problem, but can someone direct me to a PHP script which will show me how to pull the form fields in; format an HTML email with an image and a text alternative; and then send to the email address extracted from the form? I have had a look around and can't find what I'm looking for.

The more idiot-proof it is the better :-)
