PHP Adicionar Captcha a codigo de contagem

[Natan Gameron]

Preciso meio que alterar um codigo e é o seguinte o original você espera 5 segundos e pow clica no botão e redireciona mas ao invés disso quero fazer assim antes de aparecer a contagem la ter que aperta na captcha esperar ela e quando ela carregar a contagem aparecer ou voltar a contar tipo pausar caso não tenha confirmado a captcha.

Codigo do sistema:

<?php
$this->assign('title', get_option('site_name'));
$this->assign('description', get_option('site_description'));
$this->assign('content_title', get_option('site_name'));
$this->assign('og_title', $link->title);
$this->assign('og_description', $link->description);
$this->assign('og_image', $link->image);
?>

<?php $this->start('scriptTop'); ?>
<script type="text/javascript">
    if (window.self !== window.top) {
        window.top.location.href = window.location.href;
    }
</script>
<?php $this->end(); ?>
