Passing Variables through Form

Okay, I've got a form with yes/no buttons. To access this form I use misc.php?do=unsubscribe&id=1, where id=1 is the userid being unsubscribed. Now, after the user chooses to continue and unsubscribe, I need to remove their subscription using their userid. My problem is that after the user continues, the &id=1 variable is lost -- so the query cannot run. How can I get the &id=1 to pass along?

PHP Code:


		
			
// vBulletin?

$userid = $vbulletin->input->clean_gpc('g', 'id', TYPE_UINT);



// not vBulletin?

$userid = !empty($_GET['id']) ? intval($_GET['id']) : 0;

HTML Code:

<input type="hidden" name="userid" value="$userid" />

It's still not continuing along.

It will send it with your form data...

So I should be able to use $userid as it continues to the dounsubscribe page, right?

$_GET['userid'] or $_POST['userid'], depending on your form method.

Oh, I thought I used the cleaned variable.

You should clean it... just as you clean the other data coming from the form.

$userid is just ?id=X being generated into the form HTML. From there on it's just a regular form element.

Yeah I realize that, but the code you provided cleaned it -- that's what I'm using.
