Reloading Outer Page-browser From Within Iframe?

I work mostly in PHP, with just a bit of JavaScript when necessary. I've inherited an app that among other things, uploads files to the server. When the user clicks the "Save" button, it targets an invisible iframe and actions the php upload script -- that is:

Code:

<form action="doupload.php" method="post" enctype="multipart/form-data" name="doupload" target="doupload_iframe_target">

The outer, top level window has the icons for the files uploaded so far, and the total number.

The upload works fine, but the icons & total count don't get updated in the outer window unless I manually click refresh on the browser. Naturally, I'd like the new number and icon list to appear automatically after an upload, so I tried putting both:

window.location.reload(); and parent.location.reload();

at the end of the doupload.php script within the iframe (appropriately encapsulated in <script> </script>).

Both of which work, sort of, but they apparently repost the data to the iframe, which causes the upload to be re-executed, which then causes the reload to happen again, for an endless loop.

If I manually refresh the browser page from the firefox toolbar, this doesn't happen; it just refreshes and shows the new total number & appropriate icons.

So obviously I'm out of my depth here with the javascript and dom structure. I want to refresh the top window without reposting to the iframe.
