I am trying to store the Zend calendar library access object namely "service" in codeigniter controller which could be accessed in any function within the controller for future use. I tried to store it in a class variable and accessed it as "$this->service" but the object returned to empty. The next technique was to store the object in session which is also returning an empty variable. The code for the session storage of the object which I have written is as following:
My Controller:
class calendar extends CI_Controller {
function __construct(){
parent::__construct();
$clientPath = APPPATH."libraries";
$oldPath = set_include_path(get_include_path() . PATH_SEPARATOR . $clientPath);
require_once 'Zend/Loader.php';
Zend_Loader::loadClass('Zend_Gdata');
Zend_Loader::loadClass('Zend_Gdata_ClientLogin');
Zend_Loader::loadClass('Zend_Gdata_Calendar');
}
public function connect_with_google(){
// User whose calendars you want to access
$user = 'email#email.com';
$pass = 'mypassword';
$service = Zend_Gdata_Calendar::AUTH_SERVICE_NAME; // predefined service name for calendar
$client = Zend_Gdata_ClientLogin::getHttpClient($user, $pass, $service);
$service = new Zend_Gdata_Calendar($client);
$this->session->set_userdata('service', $service);
}
public function ajax_get_calendars()
{
var_dump($this->session->userdata('service'));
}
}

I am using Magento 2.3.4 inside a docker container for a payment gateway extension. First things first, here is the affected code:
<?php
namespace Magento\PGM\Block;
use Magento\AdminNotification\Model\Inbox;
use Magento\Checkout\Model\Session;
use Magento\Framework\App\ObjectManager;
use Magento\Framework\App\Response\Http;
use Magento\Framework\View\Element\Template;
use Magento\Framework\View\Element\Template\Context;
use Magento\Sales\Api\Data\OrderAddressInterface;
use Magento\Sales\Model\Order\Payment\Transaction;
use Magento\Sales\Model\Order\Payment\Transaction\Builder as TransactionBuilder;
use Magento\Sales\Model\OrderFactory;
use Magento\Store\Model\ScopeInterface;
use Magento\PGM\Logger\Logger;
class Main extends Template
{
protected $_objectmanager;
protected $checkoutSession;
protected $urlBuilder;
protected $response;
protected $config;
protected $messageManager;
protected $transactionBuilder;
protected $inbox;
private $logger;
private $orderFactory;
public function __construct(Context $context, Session $checkoutSession, OrderFactory $orderFactory = null, Logger $logger, Http $response, TransactionBuilder $tb, Inbox $inbox)
{
$this->checkoutSession = $checkoutSession;
$this->orderFactory = $orderFactory ?: ObjectManager::getInstance()->get(OrderFactory::class);
$this->response = $response;
$this->config = $context->getScopeConfig();
$this->transactionBuilder = $tb;
$this->logger = $logger;
$this->inbox = $inbox;
$this->urlBuilder = ObjectManager::getInstance()
->get('Magento\Framework\UrlInterface');
parent::__construct($context);
}
public function getParentId()
{
return $this->getData(OrderAddressInterface::PARENT_ID);
}
protected function _prepareLayout()
{
$method_data = array();
$order = $this->orderFactory->create()->load($this->getParentId());
if ($order) {
$payment = $order->getPayment();
// The error is thrown here (" Call to a member function setTransactionId() on null")
$payment->setTransactionId("-1");
...
$payment->save();
$order->save();
...
}
private function setApiData($order, $testmode, $instance)
{
...
}
}
I am getting this error:
Call to a member function setTransactionId() on null
I think that this is just a symptom though. The order object is not created, my IDE marks the $order->getPayment() method as not found at all.
The code itself should not be the problem, but the folder 'Sales\Model' does not contain an orderFactory.php file. Is the file missing or deprecated? Several modules use this file and create orders like this, for example the Paypal PGM, and use the OrderFactory.php file.
As i know The Factory class name is the name of Model class and append with the Factory word. So for our example, we will have TopicFactory class. You must not create this class. Magento will create it for you. Whenever Magento’s object manager encounters a class name that ends in the word ‘Factory’, it will automatically generate the Factory class in the var/generation folder if the class does not already exist. You will see the factory class in
ROOT/generated/code/<vendor_name>/<module_name>/Model/OrderFactory.php
So the first step you should go to the folder Generation to see the class is there or NOT.
If it's not there, i think you're are facing permission issue , magento cant generate (can't create file or folder) the Factory Class in Generation folder.
Hi orderFactory does not have payment in DB, so you cannot use this to get payment. You can try this:
use Magento\Sales\Model\ResourceModel\Order\Payment\Transaction\CollectionFactory;
protected $transactions;
public function __constructor(CollectionFactory $transactions)
{
$this->transactions = $transactions;
}
In your method:
$transactions = $this->transactions->create()->addOrderIdFilter($orderId);
...
$transactions->setTransactionId("-1");`
My middleware is similar to Auth. It checks for a URL pattern (eg: /rest/*), and then looks for token in the request, retrieves its corresponding user from database. After that, I want to save that user in a variable so that I can get back to it later in any of the following controller. What's the best way?
Middleware:
public function handle($request, Closure $next)
{
$token = Input::get("token");
// get user data from database
$user = User::get_user_from_token($token);
// ?? -> How to pass $user to controller, so that ..
return $next($request);
}
In Controller:
public function profile_save() {
// I get the user back here without querying again
$user = ???
}
I would flash the data to the session. When you flash data it only stays there until the next request.
In your middleware add
Session::flash('user', $user);
Don't forget to add this at the top of your middle ware
use Session;
Then whenever you need to access your user use
Session::get('user');
Here is a link to the docs for reference
http://laravel.com/docs/5.0/session#flash-data
I'm using Laravel 5.1.
To pass parameters from the middleware to the controller you can add it to the Request object.
In the middleware:
public function handle($request, Closure $next)
{
$user = 'DB Call To Get User';
$age = 20;
$request->route()->setParameter('user', $user);
$request->route()->setParameter('age', $age);
return $next($request);
}
Then you can get the user in the controller from either the arguments:
public function TestAction(Request $request, User $user, $age)
{}
Or explicitly from the request object:
public function TestAction(Request $request)
{
$user = $request->route()->getParameter('user');
$age = $request->route()->getParameter('age');
}
Of course you can flash the data temporarily to the session or save it to the session itself and set an expiry time, but if you only need it to last for the lifetime of the request then i think this is a good way.
Hope this helps!
Codeigniter gives a white screen every time a form is posted:
Here is the controller logic [controllers/account.php]:
class Account extends CI_Controller
{
public function create()
{
if($this->input->post(NULL, TRUE)){
$params = $this->input->post();
//add validation layer
$accountOptions = array($params are used here)
$this->load->model('account/account', 'account');
$this->account->initialize($accountOptions);
$this->account->save();
}
$header['title'] = "Create Free Account";
$this->load->view('front_end/header', $header);
$this->load->view('main_content');
$content['account_form'] = $this->load->view('forms/account_form', NULL, TRUE);
$this->load->view('account/create', $content);
$footer['extraJs'] = "account";
$this->load->view('front_end/footer', $footer);
}
}
Here is the Account Model logic [models/account/account.php]:
class Account extends CI_Model
{
public function __construct()
{
parent::__construct();
}
public function initialize($options)
{
//initialize
}
}
The view first loads fine then after filling the form and clicking submit, just white page.
I tried to add __construct to the controller and load account/account from there, the form does not even load. Any ideas?
I just found the problem:
- The Model account has duplicated definition and the error_reporting was off!
You shouldn't have two classes with the same name Account (the controller and model). Check your server and/or Codeigniter log it should show up there.
I advise you to call your controller class Account and your model class M_Account. You can then rename the model to account whenever you load it, just like you did:
$this->load->model('account/m_account', 'account');
public function __construct()
{
parent::__construct();
$this->load->model("account/account");
}
you load model,library and helper files in construct dont load to inside a function
I have a variable, contaning data that should be present in the entire site. Instead of passing this data to each view of each controller, I was wondering if there is a way to make this data available for every view in the site.
Pd. Storing this data as a session variable / ci session cookie is not an option.
Thanks so much.
Create a MY_Controller.php file and save it inside the application/core folder. In it, something like:
class MY_Controller extends CI_Controller {
public $site_data;
function __construct() {
parent::__construct();
$this->site_data = array('key' => 'value');
}
}
Throughout your controllers, views, $this->site_datais now available.
Note that for this to work, all your other controllers need to extend MY_Controllerinstead of CI_Controller.
You need to extend CI_Controller to create a Base Controller:
https://www.codeigniter.com/user_guide/general/core_classes.html
core/MY_Controller.php
<?php
class MY_Controller extend CI_Controller {
public function __construct() {
parent::__construct();
//get your data
$global_data = array('some_var'=>'some_data');
//Send the data into the current view
//http://ellislab.com/codeigniter/user-guide/libraries/loader.html
$this->load->vars($global_data);
}
}
controllers/welcome.php
class Welcome extend MY_Controller {
public function index() {
$this->load->view('welcome');
}
}
views/welcome.php
var_dump($some_var);
Note: to get this vars in your functions or controllers, you can use $this->load->get_var('some_var')
Set in application/config/autoload.php
$autoload['libraries'] = array('config_loader');
Create application/libraries/Config_loader.php
defined('BASEPATH') OR exit('No direct script access allowed.');
class Config_loader
{
protected $CI;
public function __construct()
{
$this->CI =& get_instance(); //read manual: create libraries
$dataX = array(); // set here all your vars to views
$dataX['titlePage'] = 'my app title';
$dataX['urlAssets'] = base_url().'assets/';
$dataX['urlBootstrap'] = $dataX['urlAssets'].'bootstrap-3.3.5-dist/';
$this->CI->load->vars($dataX);
}
}
on your views
<title><?php echo $titlePage; ?></title>
<!-- Bootstrap core CSS -->
<link href="<?php echo $urlBootstrap; ?>css/bootstrap.min.css" rel="stylesheet">
<!-- Bootstrap theme -->
<link href="<?php echo $urlBootstrap; ?>css/bootstrap-theme.min.css" rel="stylesheet">
If this is not an Variable(value keep changing) then I would suggest to create a constant in the constant.php file under the config directory in the apps directory, if it's an variable keep changing then I would suggest to create a custom controller in the core folder (if not exist, go ahead an create folder "core") under apps folder. Need to do some changes in other controller as mentioned here :
extend your new controller with the "CI_Controller" class. Example
open-php-tag if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class LD_Controller extends CI_Controller {
}
close-php-tag
Here LD_ is my custom keyword, if you want to change you can change it in config.php file under line# 112 as shown here : $config['subclass_prefix'] = 'LD_';
and extend this class in all your controllers as "class Mynewclass extends LD_Controller..
And in LD_controller you've to write the method in which you want to define the variable/array of values & call that array in all over the application as shown here :
defining variable :
var $data = array();
Method to get values from db through the Model class:
function getbooks()
{
$books = $this->mybooks_model->getbooks(); //array of records
$this->data = array('books'=>$books);
}
to call this variable in the views : print_r($this->data['books']);); you will get all the array values... here we've to make sure atleast one "$data" parameter needs to be passed if not no problem you can define this $data param into the view as shown here :
$this->load->view('mybookstore',$data);
then it works absolutely fine,,, love to share... have a fun working friends
you can use $this->load->vars('varname', $data);[ or load data at 1st view only] onse and use in any loaded views after this
Use sessions in your controllers
$this->session->set_userdata('data');
then display them in your view
$this->session->userdata('data');
Or include a page in base view file e.g index.php
include "page.php";
then in page.php,
add $this->session->userdata('data'); to any element or div
then this will show on all your views
I read all answers, but imho the best approch is via hook:
Create hook, let's get new messages for example:
class NewMessages {
public function contact()
{
// Get CI instance CI_Base::get_instance();
$CI = &get_instance(); // <-- this is contoller in the matter of fact
$CI->load->database();
// Is there new messages?
$CI->db->where(array('new' => 1));
$r = $CI->db->count_all_results('utf_contact_requests');
$CI->load->vars(array('new_message' => $r));
}
}
Attach it to some of the flow point, for example on 'post_controller_constructor'. This way, it will be loaded every time any of your controller is instantiated.
$hook['post_controller_constructor'][] = array(
'class' => 'NewMessages',
'function' => 'contact',
'filename' => 'NewMessages.php',
'filepath' => 'hooks',
'params' => array(),
);
Now, we can access to our variable $new_message in every view or template.
As easy as that :)
You could override the view loader with a MY_loader. I use it on a legacy system to add csrf tokens to the page where some of the forms in views don't use the builtin form generator. This way you don't have to retrospectively change all your controllers to call MY_Controller from CI_Controller.
Save the below as application/core/MY_Loader.php
<?php
class MY_Loader extends CI_Loader {
/**
* View Loader
*
* Overides the core view function to add csrf token hash into every page.
*
* #author Tony Dunlop
*
* #param string $view View name
* #param array $vars An associative array of data
* to be extracted for use in the view
* #param bool $return Whether to return the view output
* or leave it to the Output class
* #return object|string
*/
public function view($view, $vars = array(), $return = FALSE)
{
$CI =& get_instance();
$vars['csrf_token'] = $CI->security->get_csrf_hash();
return $this->_ci_load(array('_ci_view' => $view, '_ci_vars' => $this->_ci_prepare_view_vars($vars), '_ci_return' => $return));
}
}
I am trying to design a user registration form using code igniter 2.1.0. I have used the following code in the regitration.php in controllers to add users.
class Registration extends CI_Controller
{
function __construct() {
parent::__construct();
}
function index()
{
$data['main_content'] = 'registration';
// Checks to see if form validation rules were met an executed properly. If not, will return with registration form.
if ($this->form_validation->run('registration') === FALSE)
{
$data ['title'] = 'Registration';
$this->load->view('include/template', $data);
}
// If validation passes, information will be passed along to the MODEL to be processed and the account will be created.
else
{
$this->load->model('registration_model');
$this->registration_model->addUser();
$this->session->set_flashdata('success', 'Your account has been successfully created');
redirect(uri_string());
}
}
}
But it showed me an error of Call to a member function run() on a non-object. How do i correct that?
Please include
// load 'form' helper
$this->load->helper('form');
// load 'validation' class
$this->load->library('form_validation');
and try now
function __construct() {
// load controller parent
parent::__construct();
// load 'url' helper
$this->load->helper('url');
// load 'form' helper
$this->load->helper('form');
// load 'session'
$this->load->library('session');
// load 'validation' class
$this->load->library('form_validation');
}
It seems like $session class is not initializing correctly.
Check for default_ci_sessions table, if you are using sessions for database.
Check if the constructor is loading sessions library.
Check if session is in autoload.php config
For this "In order to use the Session class you are required to set an encryption key in your config file.".
add this to your config.php
$config['encryption_key'] = 'your_encryption_key_here';
