Question

I need to get the last non-empty value that $_GET['id_item'] had

session_start();

if(!isset($_SESSION['id_item']) || $_SESSION['id_item']===''  || ( isset($_GET['id_item']) && !$_GET['id_item'] === '' )){
    $_SESSION['id_item'] = $_GET['id_item'];
}else{
   /*no need to update*/
}

echo $_SESSION['id_item']   /*   Allways in blank    :S   */

And var_dump($_GET) outputs:

array(1) { ["id_item"]=> string(2) "50" } 

Any idea why the $_SESSION is not saved?

Answer 1

fix this:

$_SESSION['id_item']=='' to $_SESSION['id_item']===''

or you can use:

empty($_SESSION['id_item'])
