Problem with sessions

[darko]

Hi, is it possible to put classes in SESSION variables ?

I've created a class named ObjContratto that I use in this way:

$myContr = new ObjContratto;
$myContr->settore = 10;

now I need to use the same object, $myContr, in another page. So I put
it in a SESSION variable in this way:

session_start() ;
$_SESSION['contr'] = $myContr;


and retrieve the _same_ object from another page in this way:

session_start() ;
$myContr = $_SESSION['contr'];

but when I try to retrieve values from $myContr in this way:

$s = $myContr->settore;

it doesn't work, $s is sadly empty.

If I do an

echo $myContr;

it says "Object", so the session should work.

any idea?
tnx

You can't just store an object... That'll yield the same result as:
echo $object;

So, RTFM, as the man said. ;-)

that's ok. I've just put in session the variables I needed.

I don't do OOP -- but this works for me:

========
<?php // o0.php
class Obj {
var $y;
function invert() {
return str_rot13($this->y);
}
}
?>
--------
<?php // o1.php
require_once 'o0.php';

$x = new Obj();
$x->y = 'Pedro';
session_start() ;
$_SESSION['o'] = $x;
echo 'go to <a href="o2.php">n ext page</a>';
?>
--------
<?php // o2.php
require_once 'o0.php';

session_start() ;
$oldobj = $_SESSION['o'];
echo $oldobj->invert();
?>
========


Notice that the object definition in o2.php is loaded from o0.php
before the object is loaded from the $_SESSION array.

yes, this worked with me too, but I needed values stored in the object
instanced in the first page.
