How to Get Parent Products for Bundle & Grouped Products in Magento 2

Magento supports two types of the parent products, including bundle products and grouped products.

Today I will lead you in the simple way to get parent products: bundle and grouped products in Magento 2. The bundle and grouped products are two of the product types you can create from the backend of the Magento 2 store and they include some children. You are wondering whether it is possible to get parent product’s ids or not if you are holding the children product’s ids. Here is the right place to guide you what you should do. Lets’s come with the code snippet of each product type.

Bundle product

Go to the class Magento\Bundle\Model\Product\Type, there are two functions:

/**
* Retrieve Required children ids
* Return grouped array, ex array(
*   group => array(ids)
* )
*
* @param int $parentId
* @param bool $required
* @return array
*/
public function getChildrenIds($parentId, $required = true)
{
   return $this->_bundleSelection->getChildrenIds($parentId, $required);
}
 
/**
* Retrieve parent ids array by required child
*
* @param int|array $childId
* @return array
*/
public function getParentIdsByChild($childId)
{
   return $this->_bundleSelection->getParentIdsByChild($childId);
}
 
Configurable product: You can see the class Magento\ConfigurableProduct\Model\Product\Type\Configurable, it also has two functions:
 
/**
* Retrieve Required children ids
* Return grouped array, ex array(
*   group => array(ids)
* )
*
* @param  array|int $parentId
* @param  bool $required
* @return array
*/
public function getChildrenIds($parentId, $required = true)
{
   return $this->_catalogProductTypeConfigurable->getChildrenIds($parentId, $required);
}
 
/**
* Retrieve parent ids array by required child
*
* @param  int|array $childId
* @return array
*/
public function getParentIdsByChild($childId)
{
   return $this->_catalogProductTypeConfigurable->getParentIdsByChild($childId);
}

Grouped product

Go to the class Magento\GroupedProduct\Model\Product\Type\Grouped:

/**
* Retrieve Required children ids
* Return grouped array, ex array(
*   group => array(ids)
* )
*
* @param int $parentId
* @param bool $required
* @return array
*
* @SuppressWarnings(PHPMD.UnusedFormalParameter)
*/
public function getChildrenIds($parentId, $required = true)
{
   return $this->productLinks->getChildrenIds(
       $parentId,
       \Magento\GroupedProduct\Model\ResourceModel\Product\Link::LINK_TYPE_GROUPED
   );
}
 
/**
* Retrieve parent ids array by requested child
*
* @param int|array $childId
* @return array
*/
public function getParentIdsByChild($childId)
{
   return $this->productLinks->getParentIdsByChild(
       $childId,
       \Magento\GroupedProduct\Model\ResourceModel\Product\Link::LINK_TYPE_GROUPED
   );
}

Two functions you want to refer in the above class are getChildrenIds and getParentIdsByChild. By this way, defining the product type is the prerequisites, so for sure, you can load product and declare the function getTypeInstance as the following:

$product->getTypeInstance()->getParentIdsByChild($child->getId());

Final words

The topic is all required implementations you can get parent products: Bundle and Grouped products. I am so happy when I help you shorten much time but still get more efficient work.
