如何重定向iframe模式表单页面上的提交按钮上的父页面？

Question

Please I have a web code assignment to solve. Detailed information is highlighted Below:

Assignment is based on submitting iframe web form input to database and redirecting parent web page on click submit button on modal iframe web form.

I haven't tried any possible solution because it's out of my depth

Iframe Code Tag on Parentpage:

<iframe src="http://127.0.0.1/cms/v/index.php/fm/frontend/viewform/?form=1&lmode=1" scrolling="no" frameborder="0" style="border:none;width:100%;" allowTransparency="true"></iframe><script type="text/javascript"> var UIFORM_SRC = "http://127.0.0.1/cms/v/"; (function() { var uiform = document.createElement('script'); uiform.type = 'text/javascript'; uiform.async = true; uiform.src = ('https:' == document.location.protocol ? UIFORM_SRC : UIFORM_SRC) + 'assets/frontend/js/iframe.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(uiform, s); })();</script>
