In HTML 4, when you wanted to have some radio buttons, you'd do this...

<input type="radio" name="choice" value="a"> a
<input type="radio" name="choice" value="b"> b
<input type="radio" name="choice" value="c"> c

And since they all have the same name, you could only choose one of them.

But in XHTML, two elements can't have the same ID.

So... how do you group radio buttons all together?

Ok, stupid question - only one element can have the same id, but aren't id and name totally seperate entities?

Hmm. I thought that name was deprecated in favor of ID.

Maybe name is still supported for radio buttons? Or even all form elements?

I never really understood what happened to name.

As far as I know, "name" is the variable that gets passed via GET or POST, while "id" is the DOM handle. So you could have several things with the same name, if you wanted them to pass the same variable, but you could give them different IDs for dHTML purposes.

This is just off the top of my head, though.

I think it depends on the DOCTYPE you're using. Using the transitional DOCTYPE, this validates correctly:

code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html>

<head>

	<meta http-equiv="Content-Type" content="text/html; charset=windows-1252" />

	<title>::: Pugzly Code :::</title>

</head>

<body>

	<form name="blah" action="" method="post">

		<input type="radio" name="crap" value="1" />

		<input type="radio" name="crap" value="2" />

		<input type="radio" name="crap" value="3" />

		<input type="radio" name="crap" value="4" />

	</form>

</body>

</html>

Well, I'm looking for the strict XHTML doctype to work =)

(I haven't tried it myself. I'll do that. Tomorrow. Maybe.)

As far as I know, the name attribute for anchors, images and so on is deprecated in XHTML (maybe even gone in XHTML 1.1) - id shall be used instead. The name attribue for inputs is not deprecated though.
