ZF2 - Session rememberMe + 2xajax = Session object destruction failed - php

i've got the following problem:
I use ZF2 and if I click a link at the main-navigation the subnavigation and the content load via AJAX(two requests)
if I use
class AuthStorage extends Storage\Session {
public function __construct($namespace = null, $member = null, $manager = null) {
parent::__construct($namespace, $member, $manager);
$this->session->getManager()->rememberMe(3600);
}
}
i got the following error:
Warning: session_regenerate_id(): Session object destruction failed in [...]\vendor\zendframework\zendframework\library\Zend\Session\SessionManager.php on line 260
this warning-msg just appears just in one ajaxrequest. never in both at the same time. but it's not always in the same request....
and another weird thing: the exactly same script is working at my friends computer...
any ideas? :-(

Create your own session manager and pass it into the Container as second parameter. Don't need to delete old session to extend current. Set default delete old session to false.
<?php
namespace My\Session;
use Zend\Session\SessionManager;
class Manager extends SessionManager
{
public function regenerateId($deleteOldSession = false)
{
session_regenerate_id((bool) $deleteOldSession);
return $this;
}
}

How to create global object Laravel

I'm using Laravel 5.6 and Instagram API library.
To work with this Instagram API I need to create object $ig = new \InstagramAPI\Instagram(). And then for getting any user's information I must use $ig->login('username', 'password') every time.
So I don't want to use this function all the time. The first I want to create a global variable which will contain $ig = new \InstagramAPI\Instagram(). However, I don't know how to correctly do it.
I tried to use singleton:
$this->app->singleton(Instagram::class, function ($app) {
Instagram::$allowDangerousWebUsageAtMyOwnRisk = true; // As wiki says
return new Instagram();
});
When I called $ig->login('name', 'pass') in any method all user profile's information changed in this object, but then if I call dd($ig = app(Instagram::class)) in another Controller method I see that previous data did not save. "WTF?" - I said.
Someone tells me that singleton just promise me that there won't be created the same object, but it does not save any changes.
I tried to use sessions:
However, when I tried to set variable with object as value anything did not happen.
$ig = new \InstagramAPI\Instagram();
session(['ig' => $ig]);
I think it's because of I tried to put a large object. And from the other hand it's not secure method!
Just let me know:
How can I create an object which I could use in every method with saving change for the next actions?
When I called $ig->login('name', 'pass') in any method all user profile's information changed in this object, but then if I call dd($ig = app(Instagram::class)) in another Controller method I see that previous data did not save.
That is the correct behavior. When a new request is sent to Laravel, a new instance of the Instagram is created. I'm not sure if you understand the meaning of a singleton but in terms of Laravel, there is one instance per HTTP request.
Since the Instagram API you're using does not contain functionality to relogin, I created a class (that would be place in the app/Classes folder).
<?php
namespace App\Classes;
use InstagramAPI\Instagram;
use InstagramAPI\Response\LoginResponse;
class CustomInstagram extends Instagram {
public function relogin(LoginResponse $response) {
$appRefreshInterval = 1800;
$this->_updateLoginState($response);
$this->_sendLoginFlow(true, $appRefreshInterval);
return $this;
}
}
Change the singleton instance so it uses the App\Classes\CustomInstagram class.
$this->app->singleton(Instagram::class, function ($app) {
Instagram::$allowDangerousWebUsageAtMyOwnRisk = true; // As wiki says
return new App\Classes\CustomInstagram();
});
In order to use the Instagram object with an authenticated user, the login information will need to be persisted some how. This would be placed where the login is occurring.
try {
$response = app(Instagram::class)->login($username, $password);
if ($response->isTwoFactorRequired()) {
// Need to handle if 2fa is needed (we're not completely logged in yet)
}
// Can use session to persist \InstagramAPI\Response\LoginResponse but I'd recommend the database.
session(['igLoginResponse' => serialize($response)]);
} catch (\Exception $e) {
// Login failed
}
Then create a middleware to relogin the user to Instagram (if the login response exists). You need to register this as described here. Then, the Instagram singleton can be used in your controller.
namespace App\Http\Middleware;
use Closure;
use InstagramAPI\Instagram;
class InstagramLogin
{
/**
* Handle an incoming request.
*
* #param \Illuminate\Http\Request $request
* #param \Closure $next
* #return mixed
*/
public function handle($request, Closure $next)
{
$responseSerialized = session('igLoginResponse');
if (!is_null($responseSerialized)) {
$ig = app(Instagram::class);
$response = unserialize($responseSerialized);
$ig->relogin($response);
}
return $next($request);
}
}

Cannot declare class because its already defined

I want to make my own class in php to handle my errors I want to show to the user, for example when the user are logging in but the password or username is false.
I have a map classes with the files:
errorHandling.class.php
class errorHandling
{
public $customError;
public function setCustomError($error)
{
$this->customError = $error;
}
public function getCustomError()
{
echo $this->customError;
}
}
And in the users.class.php
when the user try's to login and it fails the else will be like:
else {
include 'errorHandling.class.php';
$errorHandle = new errorHandling();
$errorHandle->setCustomError("Username or password are wrong!");
}
Then in the login.php in the root map I have this code to call the function:
include 'classes/errorHandling.class.php';
include 'classes/users.class.php';
$errorHandle = new errorHandling();
$errorHandle->getCustomError();
Well now I get this error message but I don't understand it so I hope some of you guys can helping me out or give me some tips to improve my class.
Fatal error: Cannot declare class errorHandling, because the name is already in use in /classes/errorHandling.class.php on line 1
Every time you include a file in php, it will be loaded and run. For class definitions, you want to use require_once, which as it says, will only be loaded once.

Cannot load custom content type nodes with load_node_multiple or load_node

I have a custom content type called "program" that I am trying to load via a drupal module.
The .module file includes a class called Program that has a method called
getAllPrograms() using include_once(drupal_get_path('module', 'progs') . '/progs.php');
When i try and load nodes using either node_load() or node_load_multiple() i get one of two different errors randomly.
either:
Fatal error: Fatal error: Call to undefined function user_access() in /mypath/modules/filter/filter.module on line 1035
or
Error: Call to undefined function token_get_entity_mapping() in /mypath//sites/all/modules/contrib/token/token.tokens.inc, line 767
Note: 99% of times it is the first error, and occasionally i would recieve the token_get_entity error.
The strange thing is, while i have been trying different things to resolve the error I have been able to get both of these functions to work for a period but as soon as i clear the Drupal Cache i get the error again.
What I have tried
Disabling and enabling the user module via the database.
Checking the paths and status are correct for the main modules (system, user, block etc)
using db_select to get a list of node ids and then use node_load() (with a loop) and node_load_multiple() to load the nodes. This is one of the things that started working for a short time until i cleared the cache.
Tested to see if i can call user_access() from my .module file. This does not work and returns the same call to undefined function error.
Here is the code that I have (not progs an anonymized name)
progs.module
include_once(drupal_get_path('module', 'progs') . '/progs.php');
progs.php
if( !class_exists('progs') ):
class progs
{
//a bunch of properties
function __construct()
{
// load partial includes and objects
$this->load_partial_inclues();
//retrieve all programs that are open
$this->open_programs = Program::getAllOpenPrograms();
}
function load_partial_inclues()
{
//includes
include_once(drupal_get_path('module', 'progs') . '/core/objects/program.php');
}
}
function progs()
{
global $progs;
if( !isset($progs) )
{
$progs = new progs();
}
return $progs;
}
// initialize
progs();
endif;
Note: I load the $progs into the global space so i can call it elsewhere in my module.
program.php
if( !class_exists('Program') ):
class Program
{
//a bunch of properties
public static function getAllOpenPrograms()
{
// This is the line that causes all of the issues.
$result = node_load_multiple('',array('type' => 'program'));
dpm($result);
}
Thanks in advance!
Like Mike Vranckx mentioned, if you call progs() directly when you include it in progs.module, Drupal basically hasn't bootstrapped, i.e. hasn't started running fully yet. Suggest you put your progs() in progs_init() or similar so that Drupal will invoke it at the right time.
Here's a proposed way that follows your initial structure quite closely, and below you will see an alternative that better follows Drupal's conventions.
New progs.module
/**
* Implements hook_init().
*/
function progs_init(){
progs();
}
And modify your progs.php
// Why are you doing this check? Are you defining this class elsewhere in your project? If not you can safely ignore this
//if( !class_exists('progs') ):
// Convention is to name classes with Pascal case btw.
class progs
{
//a bunch of properties
function __construct()
{
// load partial includes and objects
$this->load_partial_inclues();
//retrieve all programs that are open
$this->open_programs = Program::getAllOpenPrograms();
}
function load_partial_inclues()
{
//includes
include_once(drupal_get_path('module', 'progs') . '/core/objects/program.php');
}
}
function progs()
{
global $progs;
if( !isset($progs) )
{
$progs = new progs();
}
return $progs;
}
A more Drupal way:
progs.module
/**
* Implements hook_init().
*/
function progs_init(){
global $progs;
// Consider using drupal_static to cache this
if( !isset($progs) )
{
module_load_include('inc', 'progs', 'progs');
$progs = new Progs();
}
}
progs.inc (convention is to use .inc)
class Progs
{
//a bunch of properties
function __construct()
{
// load partial includes and objects
$this->load_partial_inclues();
//retrieve all programs that are open
$this->open_programs = Program::getAllOpenPrograms();
}
function load_partial_inclues()
{
//includes
module_load_include('php', 'progs', 'core/objects/program');
}
}

access to extended class in symfony 1.4

so... I basically follow the practical symfony book, and encountered following problem.
I have properly (i guess) installed sfGuardPlugin, built the models, sqls etc, created user and tried to log in with the username and password entered.
i got the following error message:
Fatal error: Call to undefined method sfGuardUserPeer::retrieveByUsername() in /***/plugins/sfGuardPlugin/lib/validator/sfGuardValidatorUser.class.php on line 53
it looks quite weird to me, because the problematic part of sfGuardValidatorUser class looks like this:
// user exists?
if ($user = sfGuardUserPeer::retrieveByUsername($username))
{
// password is ok?
if ($user->getIsActive() && $user->checkPassword($password))
{
return array_merge($values, array('user' => $user));
}
}
while sfGuardUserPeer has just the empty class:
class sfGuardUserPeer extends PluginsfGuardUserPeer
{
}
that extends PluginsfGuardUserPeer, so i checked it out too:
class PluginsfGuardUserPeer extends BasesfGuardUserPeer
{
public static function retrieveByUsername($username, $isActive = true)
{
$c = new Criteria();
$c->add(self::USERNAME, $username);
$c->add(self::IS_ACTIVE, $isActive);
return self::doSelectOne($c);
}
}
that's the missing function!
so - what is wrong? why doesn't it work?
i have already tried all the solutions found with google, but none of them work :/
finally found it!
the
symfony propel:build-model
task unnecessarily generated the sfGuard classes in the model directory from the schema file located in the plugin directory, while all the classes were already present in the sfGuard folder.
geez, that shouldn't happen in such a well-developed framework and plugin...
Simply put that
public static function retrieveByUsername($username, $isActive = true)
{
$c = new Criteria();
$c->add(self::USERNAME, $username);
$c->add(self::IS_ACTIVE, $isActive);
return self::doSelectOne($c);
}
Code into your sfGuardUserPeer class, this will sort out the issue, I did the same when I got this error, it worked for me..

zend session exception on zend_session::start with forms

I'm having issues with trying to use Zend_Form_SubForm and sessions. My controller is in essance acting a wizard showing different subforms depending on the stage of the wizard. Using the example I am planning on storing the forms in a session namespace.
My controller looks like this.
include 'mylib/Form/addTaskWizardForm.php';
class AddtaskController extends Zend_Controller_Action{
private $config = null;
private $log = null;
private $subFormSession = null;
/**
* This function is called and initialises the global variables to this object
* which is the configuration details and the logger to write to the log file.
*/
public function init(){
$this->config = Zend_Registry::getInstance()->get('config');
$this->log = Zend_Registry::getInstance()->get('log');
//set layout
$this->_helper->layout->setLayout('no-sidemenus');
//we need to get the subforms and
$wizardForms = new addTaskWizardForm();
$this->subFormSession = new Zend_Session_Namespace('addTaskWizardForms');
if(!isset($this->subFormSession->subforms)){
$this->subFormSession->subforms = $wizardForms;
}
}
/**
* The Landing page controller for the site.
*/
public function indexAction(){
$form = $this->subFormSession->subforms->getSubForm('start');
$this->view->form = $form;
}
However this is causing the application session to crash out with
Uncaught exception 'Zend_Session_Exception' with message 'Zend_Session::start()
Any idea why this is having issues with the Zend Session??
thanks.
Make sure there are no spaces, new lines or any other characters sent before the session start. Especially if you have include and your <?php is prepended with space or starts on 2nd line of the file.
It's very weird, the only place I see that a message like that is sent is on lines 435 to 446 of Zend/Session.php.
Are you trying to run that code through a unit test?, check that there isn't any headers sent before initializing the Session.
