使用PHP清理GET查询URL

Question

So I've used mod_rewrite to rewrite my get query urls from /news?news_id=6 to /news/6. But now I'd like to be able to also do the same for when somebody submits a form using a get method. Right now when you submit a form it still directs you to /news/news_id=6 instead of /news/6, how would I be able to clean the get query url? I'm pretty sure this can't be done using mod_rewrite (please correct me if you can do so), so I imagine you'd need to use either Javascript or PHP. I've been trying to do this with PHP and so far I've done as follows:

 if (!empty($_GET['news_id'])) {
    $redirecturl = "/news/" . $_GET['news_id'];
    $redirecturl = str_replace(" ", "-", $redirecturl);
    header('Location: ' . $redirecturl, true, 303);
    die();
}

However this results in an error on the browser which says "localhost redirected you too many times." How would I go about achieving this task with PHP?

Thank you.

Not sure but, does it have to be a 'get' form? If you want a clean URL this would be a very simple example with the post method (without any security checks!). You can leave the 'action' empty if it's the same page:

Form code:

<form action="" method="post">
    [Other form code ]
    <input type="hidden" name="news_id" value="6" />
</form>

Process code:

if ($_POST && !empty($_POST['news_id'])) {
    // Do what you want with: $_POST['news_id'];
}

Also, you could make a new mod_rewrite where you handle your form processing, like: /news6/process for example. This would be better for security reasons and you will have much cleaner code. After you have done your processing set a session variable to let the user know if the processing was completed or not on '/news/6'.
