Help with PHP and File Attachments

[BCNorth]

Okay, I am a PHP newbie. I have a basic PHP script that I use as a contact us form. I am currently developing a new site, and want to have an add file option.

Using HTML to add the "browse" form is a piece of cake, but how do I encorporate this into the PHP submission code so that it will attache the file as an email attachement when it sends the email? Here are some snippets of my code: (Hopefully this is enough to be able to help).

// How Do I put the File into a Variable?

$name = $_POST['name'] ;
$email = $_POST['email'] ;

$messageproper =
	"Email: $email\n" .
	"Name: $name\n" .
	"\n\n\n" ;

// After the File is in the Variable, How do I add it as an Attachment in this code?

mail($mailtoweb, $subject, $messageproper, "From: \"$name\" <$email>\nReply-To: \"$name\" <$email>\nX-Mailer: chfeedback.php 2.02" );
header( "Location: $thankyouurl" );
exit ;

In addition, How can I set up a check on the attachment? I only want to accept .txt and .html file attachments - how would I check against this, so I can redirect the user to the "declined" page?

(All I really need here is the if statement)

Huge Thanks

Hey,

Can you tell name the name of the field for the file? You have Name, Email, and you should have one more field which is the attachment correct?
