读产品

    // Loading is based off of the primary key [Integer]
    //   1 would be the first one saved, 2 the next, etc.
    $product = \Drupal\commerce_product\Entity\Product::load(1);

读变体/sku

    // Loading is based off of the primary key [Integer]
    //   1 would be the first one saved, 2 the next, etc.
    $red = \Drupal\commerce_product\Entity\ProductAttributeValue::load(1);

读产品属性值

    // Loading is based off of the primary key [Integer]
    //   1 would be the first one saved, 2 the next, etc.
    $variation = \Drupal\commerce_product\Entity\ProductVariation::load(1);

某个产品是否存在某个属性值

    // Look up while filtering by Attribute
    $productAttributeId = \Drupal::entityTypeManager()
          ->getStorage('commerce_product_attribute_value')
          ->getQuery()
          ->condition('attribute', 'attribute_machine_name')
          ->condition('field_value', field_value)
          ->execute();

通过属性值创建变体

    /**

     *   The attribute value entity to use for the attribute type.

修改产品标题字段

如果你想改产品名称改成内容名称，可以通过hook：

    use Drupal\Core\Entity\EntityTypeInterface;
    /**
     * Implements hook_entity_base_field_info_alter().
     */
    function mymodule_entity_base_field_info_alter(&$fields, EntityTypeInterface $entity_type) {
      if ($entity_type->id() == 'commerce_product') {
        // Change the title field label.
        $fields['title']->setLabel(t('Product name'));
      }
    }
