I'm trying to deploy a simple plugin to a Joomla 2.5 installation. The code in the plugin that is outside the class declaration runs and adds the two script tags to the head. However, the code within does nothing. I can't change the $article->title or $article->text. I've copy and pasted, verbatim from different articles, but everything seems to talk only about 1.5. The 1.7 stuff that I do find only mentions changing onPrepareContent to onContentPrepare. Neither seems to do anything. I would appreciate any help!
<?php
// No direct access.
defined( '_JEXEC' ) or die( 'Restricted access' );
class plgContentPicasaGallery extends JPlugin
{
/**
*
* #param string The context of the content being passed to the plugin.
* #param mixed An object with a "text" property.
* #param array Additional parameters.
* #param int Optional page number. Unused. Defaults to zero.
* #return boolean True on success.
*/
public function onContentBeforeDisplay($context, &$article, &$params, $page = 0)
{
if (is_object($article)) {
$article->text = "omfg, wtf?";
return true;
} else {
$article = "omfg, I'm not an object, wtf?";
return true;
}
}
}
Joomla documentation & tutorials a little bit out dated, new framework changed few things.
To find proper signatures simply look at /plugins/content/... files.
Below is proper function signature & phpdoc for onContentPrepare.
/**
* #param string The context of the content being passed to the plugin.
* #param object The article object. Note $article->text is also available
* #param object The article params
* #param int The 'page' number
*/
public function onContentPrepare($context, &$article, &$params, $page = 0)
{
...
}
My noobishness with Joomla prevailed over my good sense. I was editing the plugin files on the server and I was expecting that to update the plugin. Thanks for the help!
you can use this method
jimport('joomla.form.helper');
$urla= JRequest::getVar('id');
$urlview= JRequest::getVar('view');
if ($urlview=='article')
{}
if ($urla==10<- number id article )
{}
i know framework joomla is good but its for understanding method

I tried to altered route it didn't work in my custom module. it is taking the altered path from contributed module. then i tried to extend the routesubscriber.php from extended module but its still didn't work.
I have cleared cache, rebuild routes, and tried to adjust weight for my custom module giving it highest weight. But still didn't work.
If anyone call help with this issue, it will be great help.
this is MyAppsRouteSubscriber.php
<?php
namespace Drupal\MyApps\Routing;
use Drupal\MyApps\Entity\ListBuilder\DeveloperAppListBuilder;
use Drupal\Core\Routing\RouteSubscriberBase;
use Symfony\Component\Routing\RouteCollection;
use Drupal\apigee_kickstart_enhancement\Routing\RouteSubscriber;
/**
* Custom MyAppsRouteSubscriber for MyApps.
*/
class MyAppsRouteSubscriber extends RouteSubscriber
{
protected function alterRoutes(RouteCollection $collection)
{
// Override the controller for the Apigee Kickstart Enhancement.
/** #var \Drupal\Core\Entity\EntityTypeInterface $app_entity_type */
foreach (\Drupal::service('apigee_kickstart.enhancer')->getAppEntityTypes() as $entity_type_id => $app_entity_type) {
if ($route = $collection->get("entity.$entity_type_id.collection_by_" . str_replace('_app', '', $entity_type_id))) {
if ($entity_type_id == 'team_app') {
$route->setDefault('_controller', TeamAppListBuilder::class . '::render');
} else {
$route->setDefault('_controller', DeveloperAppListBuilder::class . '::render');
}
}
}
}
}
and i have DeveloperAppListBuilder.php
<?php
namespace Drupal\MyApps\Entity\ListBuilder;
use Drupal\apigee_edge\Entity\DeveloperAppRouteProvider;
use Drupal\apigee_edge\Entity\ListBuilder\DeveloperAppListBuilderForDeveloper;
/**
* Renders the Apps list as a list of entity views instead of a table.
*/
class DeveloperAppListBuilder extends DeveloperAppListBuilderForDeveloper
{
/**
* {#inheritdoc}
*/
public function render()
{
//code here
}
}
First make sure your module is following the details outlined in Naming and placing your Drupal 8 module - Name your module:
It must contain only lower-case letters and underscores.
The namespace in your details indicates it is using upper camel case instead of snake cases.
Also ensure your route subscriber has a relevant my_app.services.yml services YAML file and tag it with event_subscriber or it won't be registered:
services:
my_app.route_subscriber:
class: Drupal\my_app\Routing\MyAppsRouteSubscriber
tags:
- { name: event_subscriber }
Make sure your module is enabled or it won't be working either. Debug through it to see where it still fails.
example:
path: '/example'
defaults:
_controller: '\Drupal\example\Controller\ExampleController::content'
requirements:
_custom_access: '\Drupal\example\Controller\ExampleController::access'
This custom_access checker will be executed only when someone call mywebsite.domain/example.
But I want that this controller check all urls, run independent of path.
How can I create an independent custom access controller?
The idea for preventing routing access to a very low level (Kernel one to be precise), is to register a EventSubscriber service, subscribing to the REQUEST KernelEvent.
First of all, you will need to create a new custom module.
Once done, you will be able to create a new my_module.services.yml file which will declare a new EventSubscriber
services:
my_module.subscriber:
class: Drupal\my_module\EventSubscriber\MyCustomSubscriber
tags:
- { name: event_subscriber}
Then, create the class referenced above in my_module/src/EventSubscriber/MyCustomSubscriber.php.
Here is a tiny example which checks if the current user is logged-in before accessing any page, otherwise redirect on the login page. This following code is not complete (see the last reference for a better explanation) but it shows you the basics (subscription to the event, dependency injection, event redirection, ...)
<?php
namespace Drupal\my_module\EventSubscriber;
use Drupal\Core\Routing\RouteMatchInterface;
use Drupal\Core\Url;
use Symfony\Component\HttpFoundation\RedirectResponse;
use Symfony\Component\EventDispatcher\EventSubscriberInterface;
use Symfony\Component\HttpKernel\Event\GetResponseEvent;
use Symfony\Component\HttpKernel\KernelEvents;
class MyCustomSubscriber implements EventSubscriberInterface {
/**
* The current route match.
*
* #var \Drupal\Core\Routing\RouteMatchInterface
*/
protected $routeMatch;
/**
* Class constructor.
*
* #param \Drupal\Core\Routing\RouteMatchInterface $route_match
* The current route match.
*/
public function __construct(RouteMatchInterface $route_match) {
$this->routeMatch = $route_match;
}
/**
* {#inheritdoc}
*/
static function getSubscribedEvents() {
$events[KernelEvents::REQUEST][] = ['isLoggedIn'];
return $events;
}
/**
* It verify the page is requested by a logged in user, otherwise prevent access.
*
* #param \Symfony\Component\HttpKernel\Event\GetResponseEvent $event
* A response for a request.
*/
public function isLoggedIn(GetResponseEvent $event) {
$route_name = $this->routeMatch->getRouteName();
// Don't run any assertion on the login page, to prevent any loop redirect.
// If intend to be used on a production project, please #see
// https://www.lucius.digital/en/blog/drupal-8-development-always-redirect-all-logged-out-visitors-to-the-login-page for a better implementation.
if ($route_name === 'user.login') {
return;
}
if (\Drupal::currentUser()->isAnonymous()) {
$dest = Url::fromRoute('user.login')->toString();
$event->setResponse(RedirectResponse::create($dest));
}
}
}

I have a custom module that creates a content type on installing it. If I create a content using that content type, that content does not get deleted on uninstalling the module.
How do I delete all the contents created from that content type on uninstalling the module?
Removing the module configurations on hook_uninstall is not helping.
Thanks In Advance!
You must implement the hook_uninstall in your mymodule.install file.
In this hook, you will be able to remove every content using the following code:
/**
* Implements hook_uninstall().
*/
function mymodule_uninstall() {
// Load services.
$queryFactory = \Drupal::service('entity.query')
$nodeStorage = \Drupal::entityManager()->getStorage('node');
// Query all entity.
$query = $queryFactory->get('node')
->condition('type', 'article'); // <-- Change the type here for yours.
$nids = $query->execute();
// Delete entities.
if (!empty($nids)) {
$entities = $nodeStorage->loadMultiple($nids);
$nodeStorage->delete($entities);
}
}
You could also use the entity_delete_multiple but this function is now deprecated.
https://api.drupal.org/api/drupal/core%21includes%21entity.inc/function/entity_delete_multiple/8.2.x
Hope it will help you resolve your issue.
Since #Kevin-wenger answer uses entityManager which is deprecated.
Code using entityTypeManager as follows :
/**
* Implements hook_uninstall().
*/
function MYMODULE_uninstall() {
// Delete all nodes of given content type.
$storage_handler = \Drupal::entityTypeManager()
->getStorage('node');
$nodes = $storage_handler->loadByProperties(['type' => 'MACHINE_NAME_OF_TYPE']);
$storage_handler->delete($nodes);
// Delete content type.
$content_type = \Drupal::entityTypeManager()
->getStorage('node_type')
->load('MACHINE_NAME_OF_TYPE');
$content_type->delete();
}

I want validate an entity doctrine differently when the entity is created, updated or deleted.
There is an entity constraint validator in my entity class.
// src/AppBundle/Entity/AcmeEntity.php
use AppBundle\Validator\Constraints as AcmeAssert;
/**
* #AcmeAssert\CustomConstraint
*/
class AcmeEntity
{
// ...
protected $name;
// ...
}
In my CustomConstraint I want determine if the Entity will be updated, created or delete for execute a specific validator.
Using unit of work is a solution ?
What is the best way to make this?
I think this problematic is common in lot of application ?
Thank's all ;)
You could either use validation groups based on the submitted data or handle itwhen you create the form by passing the validation group.
For example, in your controller when you create the form;
$form = $this->createForm(new AcmeType(), $acme, ['validation_groups' => ['create']]);
Then you entity would be something like;
/**
* Get name
*
* #Assert\Length(min=2, max=11, groups={"create", "update"})
* #AcmeAssert\ContainsAlphanumeric(groups={"create"}) // only applied when create group is passed
* #return string
*/
public function getName()
{
return $this->name;
}
This is what validation groups are made for.
Since Symfony Forms read validations from entity annotations and use internally the Validator component you'd have a look at these articles in the documentation:
http://symfony.com/doc/current/form/validation_groups.html
http://symfony.com/doc/current/validation/groups.html
http://symfony.com/doc/current/validation/sequence_provider.html
I have an Entity called Game with a related Repository called GameRepository:
/**
* #ORM\Entity(repositoryClass="...\GameRepository")
* #ORM\HasLifecycleCallbacks()
*/
class Game {
/**
* #ORM\prePersist
*/
public function setSlugValue() {
$this->slug = $repo->createUniqueSlugForGame();
}
}
In the prePersist method, I need to ensure that the Game's slug field is unique, which requires a database query. To do the query, I need access to the EntityManager. I can get the EntityManager from inside GameRepository. So: how do I get the GameRespository from a Game?
You actually can get the repository in your entity and only during a lifecycle callback. You are very close to it, all you have to do is to receive the LifecycleEventArgs parameter.
Also see http://docs.doctrine-project.org/projects/doctrine-orm/en/latest/reference/events.html
use Doctrine\ORM\Event\LifecycleEventArgs;
/**
* #ORM\Entity(repositoryClass="...\GameRepository")
* #ORM\HasLifecycleCallbacks()
*/
class Game {
/**
* #ORM\prePersist
*/
public function setSlugValue( LifecycleEventArgs $event ) {
$entityManager = $event->getEntityManager();
$repository = $entityManager->getRepository( get_class($this) );
$this->slug = $repository->createUniqueSlugForGame();
}
}
PS. I know this is an old question, but I answered it to help any future googlers.
You don't. Entities in Doctrine 2 are supposed to not know of the entity manager or the repository.
A typical solution to the case you present would be to add a method to the repository (or a service class) which is used to create (or called to store) new instances, and also produces a unique slug value.
you can inject the doctrine entity manager in your entity
(using JMSDiExtraBundle)
and have the repository like this:
/**
* #InjectParams({
* "em" = #Inject("doctrine.orm.entity_manager")
* })
*/
public function setInitialStatus(\Doctrine\ORM\EntityManager $em) {
$obj = $em->getRepository('AcmeSampleBundle:User')->functionInRepository();
//...
}
see this : http://jmsyst.com/bundles/JMSDiExtraBundle/1.1/annotations
In order to keep the logic encapsulated without having to change the way you save the entity, instead of the simple prePersist lifecycle event you will need to look at using the more powerful Doctrine events which can get access to more than just the entity itself.
You should probably look at the DoctrineSluggableBundle or StofDoctrineExtensionsBundle bundles which might do just what you need.
