[RESOLVED] email form validation

Hi,

I would like to have a simple form of form validation for sending emails from my website.

The way I normally do it, is I set the form action to a page called send.php

on that page I have my php mail() code and a header at the end to redirect to a response page.

All workds well.

However, I the file gets abused all the time by spamers etc.

I don't like catchpa pictures.

What I would like is to have a simple question in my form:

5+5 = ?

and on my send.php file a validation of some sort that the filed "question" should be parsing a "10" value

I am hoping this will at least reduce this kind of abuse.

I don't really know what the validation code should be on my send.php file

Could you pls help?

Thanks,

Vinny

if ($_POST['question'] != '10') {
  //put error handler here, ie die() or a redirect or w/e
}

thank you
