Sending Forms with GET variables from other forms

Hi guys, I have another question... this time about using forms and the $_GET method.

Basically, for the website I'm building I have a news posting system, and I want to have a page where you can edit the posts. When you go to the editing page, I want to be able to order it by ID or title name.

My editing page is on my index.php, but I have a few pages on there, and I use a $_GET variable to get to them.
ie. index.php?act=post index.php?act=edit

I'm also using a $_GET variable for ordering the news articles to edit/delete
ie. index.php?act=edit&sort=newsdesc

But, I'm wondering how I can send the form that holds the sort variable to the page and also keep the act variable. I thought it might be as simple as this:

<form action="index.php?act=edit" method="get">

                <input type="radio" name="sort" value="newsdesc" />

           </form>

But, all this does is send it to index.php.

Does anyone know how I could accomplish this?

You could use a hidden field set it's value to the action, or just stick it in the $_SESSION array.

<form action="index.php?act=edit" method="get">

                <input type="radio" name="sort" value="newsdesc" />

                 <input type="hidden" name="action" value="<?php print $_GET['action']" />

           </form>

Little tip: never just chuck out unescaped user input. Try this:

<input type="hidden" name="action" value="<?php echo htmlspecialchars($_GET['action']) ?>" />

Wow, I must have been tired last night... I'm not sure why that didn't occur to me.

Thanks for your help again, Ooble.

Methinks it was kruptof that gave you the solution. I just expanded on it a little.

Oh sorry, Kruptof I just read the bottom post and for some reason assumed it was Ooble both times.
