Question

I have the following variable that I get it from url:

$getdeparture = $_GET["departure"];

I want to assign a value if it is posted empty &departure=

Answer 1

Something like that?

$getdeparture = isset($_GET["departure"]) ? $_GET["departure"] : $your_value;

or

$getdeparture = !empty($_GET["departure"]) ? $_GET["departure"] : $your_value;

or

$getdeparture = isset($_GET["departure"]) && !empty($_GET["departure"])  ? $_GET["departure"] : $your_value;

Missed ! in-front of empty the first time.
