I am looking to set a session variable based on a search conducted by the user. The idea is that the search is populated with their last search wherever they go on the site.
I have the following code that I thought would set the variable if the variable geo-box was present and use the saved variable if it isn't, but this doesn't work...
session_start();
if(isset($_GET['geo-box'])){
echo $_SESSION['town'] = $_GET['geo-box'];
} else {
echo $_SESSION['town'];
}
