Problem with $_GET being undefind

[pleek]

ok so i have this function in my forum

 

function hiliteItem($item) {
$action = $_REQUEST['action'];
$active = ' class="active_menu"';
if (strtolower($item) == strtolower($action)) {
	return $active;
} elseif (strtolower($item) == "home" && $action == "") {
	return $active;
} 

 

what it does is highlight the correct tab (the one currently being used). But sense the homepage is just index.php there is no "action" for it go get. This makes it spit out errors galore saying that "action" is undefined. Can this be edited so that if the "action" == "" it doesn't make an error? again this only a cures when the url is "index.php"

Just assign action to whatever value you want if it's undefined.

$action = (isset($_GET['action'])) ? $_GET['action'] : '';

If $_GET['action'] is set, the value is $_GET['action']'s value,

otherwise it's '' (null string)
