On-Rev antispam (& reCAPTCHA)

[Alex Tweedly]

I took a similar approach, and didn't find the html + rev too akward ... 
here's what I have

>       -- with rev snippets to fill in the default data or data already

>       put round(random(8)) into t1

> ?>

> & t2 ?>:</label>
> <input type="text" name="total" size="20" maxlength="20" value="" /> 
> <br />
> <p> <input type="hidden" name="thetotal" value="<?rev put tTotal ?>" 
> /> <br />

and elsewhere when I get input, I have simply

>       put $_POST["total"] into tTotal
>       put $_POST["thetotal"] into tTheTotal

> into tErrorMessage
>       else
>          -- data ok, so set the flag
>          put true into tDataEnteredOK
>       end if
