现在是日期时间的$ _session（）

I don't know how to create a $_SESSION with this :

    $query = $db->prepare('INSERT INTO pro(reference, date_add) VALUES ( :reference, NOW() ) '); 
    $query->execute(array(
        ':reference' => $_POST['reference']
        ));

    $_SESSION['reference'] = $_POST['reference'];
    $_SESSION['date_add'] = ?

My date isn't post before, so how to create a session for my date ?

Thanks for your help !

This will give you the same result:

    //MySQL datetime format (same as NOW())
    $date = date("Y-m-d H:i:s");

    $query = $db->prepare('INSERT INTO pro(reference, date_add) VALUES ( :reference, :date ) '); 
    $query->execute(array(
        ':reference' => $_POST['reference'],
        ':date' => $date
        ));

    $_SESSION['reference'] = $_POST['reference'];
    $_SESSION['date_add'] = $date

Maybe can work this

$query = $db->prepare('INSERT INTO pro(reference, date_add) VALUES ( :reference, :date_add ) '); 
    $query->execute(array(
        ':reference' => $_POST['reference'],
        ':date_add' => time()
        ));

    $_SESSION['reference'] = $_POST['reference'];
    $_SESSION['date_add'] = time();
