473309 Simple PHP Sendmail Script Changes

I have a html site with booking form of around 20 fields currently this is send via a .asp send mail script. We have moved the site over to linux and now have a simple PHP sendmail script (replacing the ASP version), we need to amend this to send over all of the fields from the website. I will provide the web page content and the sendmail script, it just needs someone who understands PHP to get it working. Should be a simple and quick job for someone who knows PHP. I need this doing asap.
