how to check if the user didn't fill in the box

I currently use PHP to do this:

 

	$rsslink = $_POST['txtRSS'];

	if ($rsslink == "") echo "<b>You didn't specify any link to add.</b>";

 

But I want to replace it with javascript and throw a msgbox onto the screen instead. Any ideas anyone?

You don't have to replace it with JavaScript, simply add JavaScript validation as well. You should never rely on JavaScript as validation as it's client side and the user can simply disable it.

 

You'd be best off reading a tutorial on this so you understand better. Millions available on Google, just the first result.
