Hi all,

I was wondering what the general consensus might be on this:

Should one Validate Radio Buttons for an online website contact form?

I've always thought they needed nothing but validation to see if they'd 
been used or not before accepting them, and sending the user back to the 
website Home Page.
    I've used Referrer to check the pages the visitor came from, gotten 
his IP or proxy identifier IP and used Control Cache and Pragma plus 
$referrer to check that the visitor arrived from the website and nowhere 
else,  to try to be sure you can't go back to any previous page and find 
the data still in tact; sessions are always destroyed when any error 
shows up.  A counter tells  me how many attempts were made from the same 
IP or Proxy and after 3 attempts the visitor is banned for a few hours. 
Two sets of 3 failed attempts will ge him banned permanently.

BUT, does any of that negate the need to Validate a Radio Button Click?
http://phpmaster.com/form-validation-with-php/ seems to think so, but 
the code they suggest isn't exactly simple and it takes a lot of code.

I'm willing to be called wrong; no problem at all.

So, what do YOU think?

TIA & Regards,

Twayne`
