Feeds: Hook after Import done

Question

I am wondering how to implement a Hook after the import of one of my importers is finished. The last imported node and the name of the importer itself would be the parameters that i need to have at this time.

Background/Usecase:

The site I'm working on is built to control IT-projects. After the user imports the bill-positions (each one a row in a CSV file => node in Drupal), which happens monthly, the site has to check if all bill-positions for a customer have been invoiced.

This is only one example, there are many other examinations that need to be done after an import is done.

I read the Feeds API & documentation, but I didn't find anything useful.

P.S. I'm pretty new to open source and Drupal itself; so please correct me if I am missing any guideline.

Answer 1

I have never used this, but you can try hook_feeds_after_import. You will likely need to kpr the $source parameter to the hook.

You may also be able to something with Rules. Feeds events don't appear in Rules (unless there is a module I don't know about), but you may be able to trigger on the node save and update events filtered to the content type(s) that you are importing to.

Answer 2

If you're looking at this post and wondering why your hook is not working is because in the D8 version of Feeds, all hooks are gone and most of them are converted to events.

The equivalent for this hook is the event \Drupal\feeds\Event\FeedsEvents::IMPORT_FINISHED. In the event callback you’ll get an object of type \Drupal\feeds\Event\ImportFinishedEvent.

To listen to this event:

1. Define your event subscriber in your module’s mymodule.services.yml file:

    services:
      mymodule.feeds_subscriber:
        class: Drupal\mymodule\EventSubscriber\FeedsSubscriber
        tags:
          - { name: event_subscriber }

2. Create your event subscriber class in mymodule/src/EventSubscriber/FeedsSubscriber.php and subscribe to \Drupal\feeds\Event\FeedsEvents::IMPORT_FINISHED:

    <?php

    namespace Drupal\mymodule\EventSubscriber;

    use Drupal\feeds\Event\FeedsEvents;
    use Drupal\feeds\Event\ImportFinishedEvent;
    use Symfony\Component\EventDispatcher\EventSubscriberInterface;

    /**
     * (describe what your event listener does here)
     */
    class FeedsSubscriber implements EventSubscriberInterface {

      /**
       * {@inheritdoc}
       */
      public static function getSubscribedEvents() {
        $events = [];
        $events[FeedsEvents::IMPORT_FINISHED][] = 'afterImport';
        return $events;
      }

      /**
       * Called when an import has finished.
       *
       * @param \Drupal\feeds\Event\ImportFinishedEvent $event
       *   The import finished event.
       */
      public function afterImport(ImportFinishedEvent $event) {
        // (your code here...)
      }

    }
