I found a php script on the old internet that i have decided to use for a site i'm doing.

I'm pretty rubbish with php etc, but I want to try and get this work.

Everything seems to be ok with it except:

1/ I would like validation on the e-mail. I have attempted this in the ereg part.

2/ WIll this protect from spam stuff?

Thanks,

Craig

mail($mailto, $subject, $messageproper,
"From: \"$name\" <$email>" . $headersep . "Reply-To: \"$name\" <$email>" . $headersep . "X-Mailer: chfeedback.php 2.08" );
header( "Location: $thankyouurl" );
exit ;
?>

To validate an email address, you can use the next:

PHP Code:

if(!preg_match('/^[a-z0-9&\'\.\-_\+]+@[a-z0-9\-]+\.([a-z0-9\-]+\.)*?[a-z]+$/is', $email])){
 header( "Location: $errorurl" );
 exit ;
} 


Thanks for the reply, I have changed that in my code and that seems to have done the trick.

I did have to change it slightly from what you put. After $email, there is a closing ] which I removed, otherwise it didn't work.

Also, as I said, I got this from the internet somewhere, will this protect the e-mail address from spam attacks?

Yes, my orgininal line was with the POST of email ($_POST['email']) sorry for that.

About the spam, currently there is no control if anybody makes a spam script for your form and sends you 1k of mails.... the best way is to put a vertification image in it.
If your're interested, I can give you a simple one.

yes please, if you could send me a simple one, that would be great.

will i be able to easily integrate it into my existing form?
