$_FILES['item']['size']>0
what about in javascript?

A:
http://www.w3.org/TR/DOM-Level-2-HTML/html.html#ID-49531485 says:
value of type DOMString
When the type attribute of the element has the value "text", "file" or "password", this represents the current contents of the corresponding form control, in an interactive user agent.
<html>
<head><title>...</title>
<script type="text/javascript">
function foo() {
var f = document.getElementById("f1");
alert( ""==f.value ? "nothing selected" : "file selected");
}
</script>
</head>
<body>
<form>
<div>
<input id ="f1" type="file" name="x" />
</div>
</form>
<button onclick="foo()">click</button>
</body>
</html>
