>>That is a nice captcha.. most of them are so hard for people to read
that it discourages some people.
You've got a point.
Never forget that a Web site is first intended to be comfortable for the
visitor, not for the programmer.
With a captcha, the programmer can sleep quietly, but the visitor will only see
some kind of paranoid annoyance.
AS recently as yesterday I had to submit a form 3 times before I could read the
characters in the Captcha.
There are many tricks transparent to the visitor to ensure that a form is not
submitted by a robot.
One of them is to trigger the submit by Javascript on some onclick event.
The Javascript can for instance add an extra field that the action template
will check.
Most of robots don't click.
Replacing email mailto: by a form is another sort of annoyance (unless the
address must be absolutely hidden, even to a human visitor). You don't keep a
copy of the message in your email software, and many times the message is
refused because of some stupid error and you lose the content of your message.
I use this to make sure an address cannot be seen by a robot :
1º convert the address by replacing @ by % and dot by say +
function hideMail(address)
{
return replace(replace(address, "@", "%"), ".", "+", "all");
}
In any page :
<A HREF="mailto:#hideMail(Email)#" onClick="getMails(this)">
getAddress () is a javascript function which restitutes the correct address.
this way, the visitor can send the message just like the full address was in
the code :
function getMail(a)
{
a.href = a.href.replace(/+/g, ".");
a.href = a.href.replace(/%/, "@");
}
Just put these functions in your application.cfm or cfc
