Simple quest but difficult enough

[John Olav]

Ok, I'm a real newbie. Just wonder how to validate one specific input field
in a form processing script against a written variable in a form processing
script. Just as a security measure against spam. Any idea with code?

Search for captcha on google or
http://en.wikipedia.org/wiki/Captcha#PHP has a choice of captcha
scripts which can be used freely

in the form processing part;

$variable="Vali d value";
if ($_REQUEST['fieldname']!=$variable)
{
// the value of fieldname does not match variable.
// Handle error here
}
else
{
// Continue processing form
}
