Hi,

function unsetUserData() {
        global $user;
        $user_data = unserialize($user->data);
        unset($user_data['variable_which_i_created_before']);
        user_save( $user , $user_data);

I think you need to do something like this:

function unsetUserData() {
        global $user;
        $user_data = array();
        unset($user->variable_which_i_created_before);
        user_save( $user , $user_data);   
}

You may take a look at user_save but I'm pretty sure it takes all of the unsaved key values from the user object and saves them in the data array.

Function is called in Menu callback function.


function module_menu() { 
  .
  .
  .
  $items['module/user/logout'] = array(
    'page callback' => 'module_logout',
    'access callback' => TRUE,
    'type' => MENU_CALLBACK,
  );
  .
  .
  .
}


function module_logout() {
  $userHandler = new IsUsers();
  $userHandler->logoutUser();
  drupal_goto('module/user/login');    
}

Class IsUsers is for another system users (lets call IS).
I save infomation about IS user login into drupal user variable.

    public function login($vals) {
        global $user;
        $user_data = array(
            'Login'  => $vals['IDLogin'],     
            'Role'   => $vals['IDRole'],   
            'Unit'   => $vals['IDUnit'],    
            'expire'    => time() + 30 * 60     
        );
        $updated_user = user_save( user_load($user->uid) , $user_data);
    }

And when IS user logout I want to clear drupal user data related to IS login (Login, Role, Unit, epire).

    public function logoutUser() {
        global $user;
        $user_data = array();
        unset($user->Login, $user->Role, $user->Unit, $user->expire);
        user_save( $user , $user_data);  
    }

I know 'account' is a default value for user_save category argument. But pass it manually to the user_save.
Without it, it didn't work for me when I wanted to update user.

Best,
Marjan

You forced me to open up my project and look how we actually do it. I just remembered wrong :)

function unsetUserData() {
        global $user;
        $user_data = array('variable_which_i_created_before' => NULL);
        user_save( $user , $user_data);   
}

This is definitely working for us. I hope it works for you.
