I am getting an error. I have shared the necessary code below. When I add kernel code, this error goes away and it works fine, but it causes other errors to not appear. What do you think could be the problem?
class TrendyolController extends Controller
{
public $baseUrl;
public $guzzle;
public $businessId;
public $marketplaceSettings;
public $authentication;
public function __construct()
{
// Set base url
$this->baseUrl = env('TRENDYOL_BASE_URL');
// Set guzzle
$this->guzzle = new Client();
// Set business id
$this->businessId = Session::get('user.business_id');
// Set marketplace settings
$this->marketplaceSettings = Business::find($this->businessId);
// Set authentication
$this->authentication = base64_encode($this->marketplaceSettings
->trendyolExternalKey1 . ':' .
$this->marketplaceSettings->trendyolExternalKey2);
}
}

I'm not understanding how to use the initialization function in the code below. Can you explain it to me?
Class A
{
protected $classB;
public function __construct()
{
$this->classB = new ClassB();
}
}
Class A
{
protected $classB;
public function __construct(ClassB $classB)
{
$this->classB = $classB;
}
}
in the second way you always have to make your object like this.
$clasa = new ClassA($classb);
in the first way you are creating the object inside of the constructor.
the second way is an injection. and could be usefull when for example you need some attributes already seted in the object.
I want to set the session after user login in opencart-3.0.2.0
I am new to opencart, I have just created this two files only in the corresponding folder.anything else I need to be done to trigger the event.
I am referring this link to trigger the event in opencart:https://isenselabs.com/posts/opencart2-event-system-tutorial
I have searched a lot on google still no result found.
Code that I am using to trigger event in opencart.
path : admin/controller/module/mymodule.php
Code :
public function install() {
$this->load->model('extension/event');
$this->model_extension_event->addEvent('mymodule', 'pre.admin.store.delete', 'module/mymodule/on_store_delete');
$this->model_extension_event->addEvent('mymodule', 'post.customer.login', 'module/mymodule/post_customer_login_customtoken');
$this->model_extension_event->addEvent('mymodule', 'post.customer.logout', 'module/mymodule/post_customer_logout_function');
}
public function uninstall() {
$this->load->model('extension/event');
$this->model_extension_event->deleteEvent('mymodule');
}
public function on_store_delete($store_id) {
$this->load->model('setting/store');
$store_info = $this->model_setting_store->getStore($store_id);
$admin_mail = $this->config->get('config_email');
mail($admin_mail, "A store has been deleted", "The store " . $store_info['url'] . " was deleted.");
}
}
path : catalog/controller/module/mymodule.php
Code :
<?php
class ControllerModuleMyModule extends Controller {
public function post_customer_login_customtoken() {
$str = 'abcdefghigklmnopqrstuvwxyz';
$shuffled = str_shuffle($str);
$this->session->data['custom_token'] = $shuffled;
}
public function post_customer_logout_function(){
$this->log->write("post_customer_logout_function");
unset($this->session->data['custom_token']);
}
}
That tutorial is for OpenCart 2.0 - 2.1, in OpenCart 2.2 and above Event system has been changed.
For OpenCart 3.0.2.0 instead of:
$this->load->model('extension/event');
// and
$this->model_extension_event->addEvent
use:
$this->load->model('setting/event');
// and
$this->model_setting_event->addEvent
Instead of:
'post.customer.login'
use:
'catalog/controller/account/login/after'
Instead of:
deleteEvent
Use:
deleteEventByCode
So it must be:
admin\controller\extension\module\mymodule.php
public function install(){
$this->load->model('setting/event');
$this->model_setting_event->addEvent('mymodule', 'catalog/controller/account/login/after', 'extension/module/mymodule/after_customer_login_customtoken');
}
public function uninstall(){
$this->load->model('setting/event');
$this->model_setting_event->deleteEventByCode('mymodule');
}
catalog\controller\extension\module\mymodule.php
class ControllerExtensionModuleMyModule extends Controller {
public function after_customer_login_customtoken(){
$this->log->write('test');
}
}
I encounter with one strange line of code in the larvel 5.0
echo (new static)->getMorphClass();
This echo the namespace of the model. Now didn't understand how come new and static are used at once.
PHP version is 5.6.3
new static is just a php construct and has nothing to do with Laravel. The static keyword references the current class, so new static is nothing more than a call to the current class constructor.
Consider this example:
class Cat {
private function __construct($type)
{
$this->type = $type;
}
public static function getACat($newType)
{
return new static($newType); // same as 'return new Cat($newType);'
}
public function print()
{
echo $this->type;
}
}
$cat1 = Cat::getACat("Fatty");
$cat1->print(); // --> Fatty
I have a Zend Framework controller with an editAction().
class WidgetController extends BaseController
{
public function editAction()
{
//code here
}
}
This controller extends a base controller which checks if the user is logged in before allowing the user to edit a record.
class BaseController extends Zend_Controller_Action
{
public function init()
{
if ($this->userNotLoggedIn()) {
return $this->_redirect('/auth/login');
}
}
}
However, now that I am performing an AJAX request, I will be sending a JSON response back, so a redirect will no longer work. I need to stop further controller execution so I can immediately send a response:
class BaseController extends Zend_Controller_Action
{
public function init()
{
if ($this->userNotLoggedIn()) {
if ($this->_request->isXmlHttpRequest()) {
$jsonData = Zend_Json::encode(array('error'=>'You are not logged in!'));
$this->getResponse()
->setHttpResponseCode(401)
->setBody($jsonData)
->setHeader('Content-Type', 'text/json');
//now stop controller execution so that the WidgetController does not continue
} else {
return $this->_redirect('/auth/login');
}
}
}
}
How can I stop controller execution?
I would define the user not being logged in and trying to make an XMLHTTPRequest as an exceptional state and let the error handler deal with it by throwing an exception (which stops dispatching of the current action). That way you are also able to handle other kinds of exceptions that might happen:
class BaseController extends Zend_Controller_Action
{
public function init()
{
if ($this->userNotLoggedIn()) {
if ($this->_request->isXmlHttpRequest()) {
throw new Exception('You are not logged in', 401);
} else {
return $this->_redirect('/auth/login');
}
}
}
}
class ErrorController extends Zend_Controller_Action
{
public function errorAction()
{
$errors = $this->_getParam('error_handler');
$exception = $errors->exception;
if ($this->_request->isXmlHttpRequest()) {
$jsonData = Zend_Json::encode($exception);
$jsonData = Zend_Json::encode(array('error'=> $exception->getMessage()));
$isHttpError = $exception->getCode() > 400 && $exception->getCode();
$code = $isHttpError ? $exception->getCode() : 500;
$this->getResponse()
->setHttpResponseCode($code)
->setBody($jsonData)
->setHeader('Content-Type', 'application/json');
} else {
// Render error view
}
}
}
I can think of many ways to stop the controller at this point in your code.
//now stop controller execution so that the WidgetController does not continue
For one, you can replace that line with this the following:
$this->getResponse()->sendResponse();
exit;
That may not be the cleanest but gets the job done rather nicely. The other option is going to be to change the action of the request in the init and let another action handle it. Replace that line with this:
$this->getRequest()->setActionName('invalid-user');
Because your already inside the dispatcher, it's going to run an action inside your action class whether you want it to or not. Trying to change the request in preDispatch will do nothing to change this dispatch. It's determined at this point to run an action inside your class. So, make an action to handle it.
public function invalidUserAction()
{
$this->_helper->layout->disableLayout();
$this->_helper->viewRenderer->setNoRender();
}
For more information see Zend_Controller_Dispatcher_Standard::dispatch.
Usually it is possible to put any domain object into session ($GLOBALS['TSFE']->fe_user) as they get automatically serialized and deserialized correctly. But in some cases this fails (i suppose caused by circurlar references or the serialized data exceeds the limit of the database blob field).
I found a better approach, converting the domain objects to integer "ids" on serialization and getting the real domain objects back from repository on deserialization:
class PutMeIntoSession implements \Serializable {
protected $project = null;
public function getProject() {
return $this->project;
}
public function setProject(\Vendor\Ext\Domain\Model\Project $project = NULL) {
$this->project = $project;
}
public function serialize() {
$serialized = serialize(array(
'project' => $this->project ? $this->project->getUid() : 0
));
return $serialized;
}
public function unserialize($serialized) {
$objectManager = GeneralUtility::makeInstance(ObjectManager::class);
$unserialized = unserialize($serialized);
$this->project = $objectManager->get(ProjectRepository::class)->findByUid($unserialized['project']);
}
}
This seems to work fine. But i don't know if there are smarter ways to achieve this or if there are any possible problems with my approach?
