[SOLVED] Need help, "if then" with getting a URL param

[jeffphp]

for a ppc campaign I'm running, to improve my quality score I'm pulling my adwords keyword from the URL.

 

site.com/index.php?kw=my keyword

 

in the page I pull the kw using

 

<?echo $_GET['kw'] ?>

 

Now the page will look bad if someone clicks around, comes back via a normal link and sees an empty space

 

How can I make this so

 

<?echo $_GET['kw'] ?>  IF  kw exists, or if kw doesn't exist, default to "something I choose"

 

Thanks!

 

Jeff

<?php

if (isset($_GET['kw'])){
   //keyword DOES exist, show whatever.

} else {
   //DOES NOT exist, show default

}

?>

If you are just wanting to set the variable, you can do this

<?php
$kw = (isset($_GET['kw'])) ? $_GET['kw'] : 'something you choose';
?>
