Good call.
<?php
// check the answer
if (strtolower($_POST['human_verifier']) != 'blue')
{
// incorrect
echo 'Robot! Get out!');
}
else
{
// correct
echo 'Welcome, Human.';
}
?>
I agree that Mike's form is well made too. It takes my concept and adds
in all the other pieces you'd want for the complete solution.

You can make that a little more foolproof by setting the case of the
text before matching, upper or lower it doesn't matter, but either way
it'll prevent answers like Blue, BLUE, bLuE, etc. from triggering the
"Robot! Get out!" error.
Respectfully,

If you want to avoid captchas, my recommendation would be to add a
question that would foil a robot. Just explain that this field is for
that specifically.
Something like:
<fieldset>
<legend>Human Verification</legend>
<p>This section is used to thwart evil spam robots. Fill in the
correct answer.</p>
<div>
<label>What color is the sky? (hint: blue)</label>
<input type="text" name="human_verifier">
</div>
</fieldset>
You're PHP would be:
<?php
// check the answer
if ($_POST['human_verifier'] != 'blue')
{
// incorrect
echo 'Robot! Get out!');
}
else
{
// correct
echo 'Welcome, Human.';
}
?>
This is obviously a very, very simple solution but it has worked on
reducing/removing form spam on a couple of my sites quite well while
being an accessible solution. I'm welcome to an contradictory
thoughts on this.

* Hi All, *
* This is a mixed question, I have a contact form that I’m building.
I want to add a human verifier to the forms but not a captcha one
because they are far from accessible, I’m not that good at PHP
though to figure it out, I already use the Mikes Green Beast form
for general contact but this will be to process order request. I’ve
trawled the internet but all I can find is captcha solutions, can
any one point me in the right direction? *

* Many thanks *
