public function MigrateProduct::onPreRowDelete in Commerce Migrate 3.1.x

Same name and namespace in other branches

1. 8.2 src/EventSubscriber/MigrateProduct.php \Drupal\commerce_migrate\EventSubscriber\MigrateProduct::onPreRowDelete()
2. 3.0.x src/EventSubscriber/MigrateProduct.php \Drupal\commerce_migrate\EventSubscriber\MigrateProduct::onPreRowDelete()

Reacts to the PRE_ROW_DELETE event.

For commerce_product rollbacks we want to preserve the product variations and prevent the 'usual' commerce behavior of deleting all variations belonging to a product when deleting that product. That is done by unsetting the variations field on the product and saving the product before it is deleted.

Parameters

\Drupal\migrate\Event\MigrateRowDeleteEvent $event: The event.

File

src/EventSubscriber/MigrateProduct.php, line 37

Class

MigrateProduct

Handles product and product variation references.

Namespace

Drupal\commerce_migrate\EventSubscriber

public function onPreRowDelete(MigrateRowDeleteEvent $event) {
  $destination_config = $event
    ->getMigration()
    ->getDestinationConfiguration();
  if ($destination_config['plugin'] === "entity:commerce_product") {
    $product_ids = $event
      ->getDestinationIdValues();
    foreach ($product_ids as $product_id) {

      /** @var \Drupal\commerce_product\Entity\product $product */
      $product = Product::load($product_id);
      if ($product && $product
        ->hasVariations()) {

        // Save the product, keeping the variations.
        $product
          ->setVariations([]);
        $product
          ->save();
      }
    }
