PHP coders - quick question

[fusionx]

How do I do this:

IF $_GET['cat'] = 0 OR $_GET['cat'] IS NULL
myCat = 0
else
myCat = $_GET['cat']
END IF

Basically, if there is a request var called "cat" and it is zero, null, or if it doesn't even exist, set a var myCat to zero.
Otherwise, set the var to whatever it currently contains.

Thanks in advance!

if(!empty($_GET['cat']))
$myCat = $_GET['cat'];
else
$myCat = defaultValue;

if(!empty($_GET['cat']))
$myCat = $_GET['cat'];
else
$myCat = defaultValue;

Isl ?cat=0 still considered empty?

[Aric]

as far as I know in newer versions of PHP, 0 is empty.. you can also use

!isset($_GET['cat']) if !empty() doesn't work out for ya

Thanks very much! It works well.

empty($_GET["cat"]) ? ($myCat=0) : ($myCat=$_GET["cat"]);

That's basically what i use.

if($_GET['cat'] < 1){$_GET['cat']=0}

if cat is a numeric value, like a category id or something, you can do:
$myCat=intval($_GET['cat']);
