[PHP] passing an object using session var

2006-11-29 Thread list arama 

Why am I not able to access the obj name field in script 2?

thanks in advance,

--script1---

?php

include(TestClass.php);

session_start();
session_register('obj');

ob_start();

$obj = new TestClass();

$obj-setName('MyName');
$obj-display();// outputs 'MyName'

header(Location:
http://localhost/~lr/webProj/photoAlbum2/sessionReceiveObj.php;);  //
re-direct to script2

ob_flush();

?

---script 2

?php

include(TestClass.php);

session_start();

$newObj = $HTTP_SESSION_VARS['obj'];

$newObj-display();   // no output, meaning no data?

$newObj-setName('Michael');
$newObj-display();  // outputs 'Michael' using obj methods

?

Try that:

 --script1---
?php
 include(TestClass.php);
session_start();

$obj = new TestClass();
$obj-setName('MyName');
$obj-display();// outputs 'MyName'

$str_object = serialize($obj); //-- You need to serialize an object ( see 
php.net manual ) in order to make an object working via session

$_SESSION['obj'] = $str_object: //-- save serialized string in the 
session,note: Use $_SESSION instead of session_register();

header(Location: 
http://localhost/~lr/webProj/photoAlbum2/sessionReceiveObj.php;);  // re-direct 
to script2

---script 2
?php
include(TestClass.php);
session_start();

$newObj = unserialize($_SESSION['obj']); //-- convert string back into object
$newObj-display();   // MyName

session_register() et al are going the way of the dino.
just use $_SESSION directly, just remember to call session_start()
before you try to use $_SESSION


 ob_start();

 $obj = new TestClass();

 $obj-setName('MyName');
 $obj-display();// outputs 'MyName'

It might be worth noting that if you are using php4 remember to pass
your object by reference when setting/retrieving from the session.

Re: [PHP] passing an object using session var

2006-11-29 Thread list arama 

Here's what I came up with:

--script1---
?php
include('TestClass.php');
session_start();
$obj = $_SESSION['obj'];
// session_register($obj);// recommended not to use - said to be
outdated usage
ob_start();
$obj = new TestClass();
$obj-setName('MyName');
$obj-display();
header(Location: http://localhost/~mdl/webProj/photoAlbum2/receive.php;);
ob_flush();
?
---script2---
?php
include(TestClass.php);
session_start();
$newObj = $_SESSION['obj'];// this works
//$_SESSION['obj'] = $newObj;   // this doesn't work
$_SESSION['obj']-display();//
$newObj-display();// this doesn't
$_SESSION = array();// unsets session having effect that script fails on
every second call
?

My only remaining question is why the session fails every second time if the
session is emptied and destroyed. Shouldn't script1 initialize a totally new
session and populate with fresh session vars?
