Check if any variables are passed in a GET
<p>I've done a few searches and not come up with anything, I'm sure it's obvious.</p>

<p>Basically I'm trying to work out if anything has been passed via GET from a form.</p>

<p>I know how to check for individual elements, but I just want to do a quick check if anything at all is passed</p>

<p>Cheers</p>
