Persistent Object Problem...!! 1

[FOR111]

Hi all,

I was wondering how it is possible to keep an instance of an object between scripts!? what is usually done in this case!

Thanks

store the object in a session element.

Hi jpadie..and thanks once again for your suggestions..

you mean that if i create a new class instance i can store that instance in a session variable:

$_SESSION['myUser'] = $clsUser;

Then to retrieve the class i would use:

$instanceUSer = $_SESSION['myUser'];
$instanceUSer->ID();

Is that correct?

Thanks for your input..much appreciated.

yup. can't see any reason why that wouldn't work.

of course - php needs to know about the class of the object before the session is started thus you cannot use session autostart.

Hi jpadie once again...

i'm getting this error now:

Fatal error: GUI_LOGIN_USER() [<a href='function.GUI-LOGIN-USER'>function.GUI-LOGIN-USER</a>]: The script tried to execute a method or access a property of an incomplete object. Please ensure that the class definition &quot;clsEncryptSystem&quot; of the object you are trying to operate on was loaded _before_ unserialize() gets called or provide a __autoload() function to load the class definition in /IntranetStandard/admin/bin/functions/_user_functions.php on line 25

Thanks for any help in providing answers..

that's what i said above.
you must include the class before you start the session.

require "classdefinition.php";
session_start();

otherwise php does not know how to unserialise the object.

The problem is that the server has already have the auto_start enabled within the php.ini. I tried this init_set('auto_start', '0') at the beginning but its not helping much! is there another way to tackle this problem?

Thanks

 

[jpadie]

yes. turn off auto_start in the php.ini file.
the alternative is to serialise the object yourself and then store the serialised string in a session element.

you can then unserialise the string programmatically (but not automatically) after you have declared the class.

$_SESSION['myUser'] = serialize ($instanceUSer);

and in reverse

require_once ("classdefinition.php");
$instanceUSer = unserialize($_SESSION['myUser']);

Hi again,

unfortuntely we're still in the same place;

i turned off auto_start and re-written the script as shown above. though now its saying that the object does not exist!

Thanks

 

[jpadie]

if you have turned off autostart then go back to the original script, which is neater anyway!
