Hi people,
As I understand it, object are unserialized into their former Class, if
that Class is in memory. That's right, right?
Well, consider the following code:
include_once("../config.inc.php");
include_once($WORKDIR."obj/foto.obj.php");
if($type == 1)
{
$foto = new Foto();
}
if(isset($_SESSION['foto']))
{
$foto = unserialize($_SESSION['foto']);
}
$foto->makeInputFoto($type);
$_SESSION['foto']=serialize($foto);
It's for a page that can edit or add a foto in(to) the database. If I run
it like this, with ?type=1 in the URL, it works the first time, but after a
reload of the exact same page, I get a 'Call to a member function on a
non-object' in the line '$foto->makeInputFoto($type);'. Why is that? It's
already a Foto-object, because I unserialized it, isn't it?
I also tried:
if($type == 1 && !isset($_SESSION['foto']))
{
$foto = new Foto();
}
elseif(isset($_SESSION['foto']))
{
$foto = unserialize($_SESSION['foto']);
}
With exactly the same effect. Any idea on how I can solve this? Tia!
