Undefined index: orderBy
|

| Hi,
I have the following code to determine how I want my results (pulled from a
database) ordered.
if (!$_GET['orderBy']) {
$orderBy = "startDate";
} else {
$orderBy = $_GET['orderBy'];
if ($orderBy=="") {
$orderBy = "startDate";
}
}
I can't remember (been a while since I've used php) how to determine whether
or not a query string variable is present and if it isn't return a value for
the defined variable. At the moment, when no query string is present I get
the error: Notice: Undefined index: orderBy
When there is a query string, obviously there is no error.
Many thanks in advance.
Cheers
Hamish
