Does anyone know how to make CAPTCHA work in a php_self file?
I have made a form, and when you click submit the results load on the same page.
The form works fine, it just doesnt seem to realise I am putting anything in the CAPTCHA field.
If I put the right code in processes the form and if i dont put the right code in, it still processes the form :)

Not sure where i went wrong

Here is the code from my form

<?php
session_start();
?>

if(!x && d.getElementById) x=d.getElementById(n); return x;

$_SESSION['captcha_keystring']

you are not assigning any value to this session variable!
i cant see the part where you are generating the keystring! sorry i have not read the whole code as it is little long

you might want to take another look at your code and check that you are first creating the captcha then assigning it to session variable and then then check whether it equals to $_POST['keystring'] or not then unset it
