have the form's action send the data to a php page or script on the same page:
In the script you can either list each form variable separately or gather all the form variables in one go.....then all you do is:
mail("whoever@foobar.com","$subject","$message","from: you@your-site.com");
$message can either be something like:
//whatever the inputs of your form are called...like $message = "name=$name, email=$email, address=$address, etc";
or gather all the info using $HTTP_POST_VARS or $HTTP_GET_VARS (depending on which method you used to send your form data)
Or you can download a generic form handler script from www.weberdev.com which outputs whatever the form contains.
