How to find out master product of simple product? - php

Question

How can I find out, if a simple product is part of a configurable product and then get the master product? I need this for the product listing.
Just found out:
$_product->loadParentProductIds();
$parentIds = $_product->getParentProductIds();

Answer 1

Let's say that you have your simple product's Product ID.
To get all the parent configurable product IDs of this simple product, use the following code:-
<?php
$_product = Mage::getModel('catalog/product')->load(YOUR_SIMPLE_PRODUCT_ID);
$parentIdArray = $_product->loadParentProductIds()
->getData('parent_product_ids');
if(!empty($parentIdArray)) {
// currently in the master configurable product
print_r($parentIdArray); // this prints all the parent product IDs using your simple product.
}
?>
I suppose this should get you going.

For Magento 1.4.2 and above use the following method instead:
$configurable_product_model = Mage::getModel(‘catalog/product_type_configurable’);
$parentIdArray = $configurable_product_model->getParentIdsByChild($simple_product_id);

After version 1.4.2.0 the loadParentProductIds() and getParentProductIds() methods are deprecated. Don't ask me why. Personally I kind of liked those methods. So I've reintroduced them to my local Mage classes. This is how:
Copy
app/code/core/Mage/Catalog/Model/Product.php
to
app/code/local/Mage/Catalog/Model/Product.php
and change the loadParentProductIds() method, found around line 1349 to:
public function loadParentProductIds()
{
return $this->_getResource()->getParentProductIds($this);
}
This piece of code will query its resource for its parent product ids. For this to work we'll need to rewrite the getParentProductIds() method in the resource class.
So copy:
app/code/core/Mage/Catalog/Model/Resource/Eav/Mysql4/Product.php
to
app/code/local/Mage/Catalog/Model/Resource/Eav/Mysql4/Product.php
Find the deprecated getParentProductIds() method. Should be somewhere around line 535. Overwrite it with the pre 1.4.2.0 code:
public function getParentProductIds($object){
$childId = $object->getId();
$groupedProductsTable = $this->getTable('catalog/product_link');
$groupedLinkTypeId = Mage_Catalog_Model_Product_Link::LINK_TYPE_GROUPED;
$configurableProductsTable = $this->getTable('catalog/product_super_link');
$groupedSelect = $this->_getReadAdapter()->select()
->from(array('g'=>$groupedProductsTable), 'g.product_id')
->where("g.linked_product_id = ?", $childId)
->where("link_type_id = ?", $groupedLinkTypeId);
$groupedIds = $this->_getReadAdapter()->fetchCol($groupedSelect);
$configurableSelect = $this->_getReadAdapter()->select()
->from(array('c'=>$configurableProductsTable), 'c.parent_id')
->where("c.product_id = ?", $childId);
$configurableIds = $this->_getReadAdapter()->fetchCol($configurableSelect);
return array_merge($groupedIds, $configurableIds);
}
Now you once again can do this:
$_product->loadParentProductIds()->getData('parent_product_ids');
Hope this helps you out!
