Answer 1

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.

Answer 2

The best and simplest thing to do is to use the form target element

<form action="..." target="_top"> 
<form action="..." target="_parent">

either of the target parameters works fine
