[ragtek]

PHP Code:

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


check:

PHP Code:

$vbulletin->input->clean_array_gpc('p', array(
                        'humanverify'    =>    TYPE_ARRAY
                    ));
        require_once(DIR . '/includes/class_humanverify.php');
        $verify =& vB_HumanVerify::fetch_library($vbulletin);
        if (!$verify->verify_token($vbulletin->GPC['humanverify']))
        {
            standard_error(fetch_error($verify->fetch_error()));
        }
