In the ASKING stage, add:

PHP Code:

require_once(DIR . '/includes/class_humanverify.php');
$verify =& vB_HumanVerify::fetch_library($vbulletin);
$human_verify = $verify->output_token(); 


Use $human_verify in your template. Then in the verifying stage, add:

PHP Code:

$vbulletin->input->clean_gpc('r', 'humanverify', TYPE_ARRAY);

require_once(DIR . '/includes/class_humanverify.php');
$verify =& vB_HumanVerify::fetch_library($vbulletin);

if (!$verify->verify_token($vbulletin->GPC['humanverify']))
{
    eval(standard_error(fetch_error($verify->fetch_error())));
}
