PHP "header (location)" isnide IFRAME, to load in _top location?

Question

Hi Webmasters.

I have a simple form which is inside IFRAME. When user click on SUBMIT, it redirects to a specific page on my server. The function I use for the redirect is

 header ('Location: mypage2.html');
exit ();

But I want the new page to open in _top location, not inside the same IFRAME that I use. How can I tell the browser to open the new page in _top not inside the IFRAME? Thanks in advance.

Answer 1

You are not able to achieve the desired effect in PHP. This is something you'd have to do from JavaScript or add target attribute to <form>:

<form ... target="_top">

Answer 2

You can use javascript to access the parent. You could echo out javascript in your PHP.. so your parent page has this:

function changeURL( url ) {
    document.location = url;
}

and in your php script, you echo

<script>
   parent.changeURL('mypage2.html' );
</script>

The reason you can't call parent.document.location is because it's read only - you have to have a function available on the parent to do it.
