How to find all bundle products that contain a simple

Question

I need to find a way to programatically find all the bundle products that contain a particular simple product. I'm hoping there is a simple solution this problem as I have been unable to figure one out myself.

Answer 1

The following should get you started. This isn't the most performant way to do this — we're loading a collection of bundled products, getting the children IDs, and then checking those IDs for what we want. However, it should be suitable for shell scripting needs, some frontend store needs, and should give you pointers towards fetching this information in a more performant way by examining how the core methods fetch the data (i.e. which resource models, leading to which tables).

Tested in Magento CE 1.7.0.1

function findBundledProductsWithThisChildProduct($id_to_find)
{
    //grab all bundled products
    $bundles = array();
    $products = Mage::getModel('catalog/product')
    ->getCollection()
    ->addFieldToFilter('type_id','bundle');

    //loop over bundled products
    foreach($products as $product)
    {

        //get child product IDs
        $children_ids_by_option = $product
        ->getTypeInstance($product)
        ->getChildrenIds($product->getId(),false); //second boolean "true" will return only
                                                   //required child products instead of all          

        //flatten arrays (which are grouped by option)  
        $ids = array();
        foreach($children_ids_by_option as $array)
        {
            $ids = array_merge($ids, $array);
        }

        //perform test and add to return value
        if(in_array($id_to_find, $ids))
        {
            $bundles[] = $product;
        }
    }

    return $bundles;
}

//usage
$products = findBundledProductsWithThisChildProduct($simple_product_id);
foreach($products as $product)
{
    var_dump($product->getData());
}

i know this is way too after the fact to be useful to you, but for future searchers...

janw's basic answer is right, but a more magento-ey way to do it would be:

$parentIds = Mage::getResourceSingleton('bundle/selection')->getParentIdsByChild($product->getId());

then you can load a product collection filtering on those ids.

I saw the answer of Alan Storm. But what if I have already have 100 bundle products. Then you would need to loop over all those :(

I figured out a way to query this:

<?php
function get_bundle_product_by_simple_id($id) {
    $read= Mage::getSingleton('core/resource')->getConnection('core_read');

    // fetch read database connection that is used in Mage_Core module
    $read = Mage::getSingleton('core/resource')->getConnection('core_read');

    $query = sprintf("SELECT `parent_product_id` FROM `catalog_product_bundle_selection` WHERE `product_id` = '%s'",
            htmlspecialchars( stripslashes( $id ) )
        );
    $value=$read->query( $query );
    $row = $value->fetch();

    if( is_null($row) ) {
        return $row;
    }
    return $row['parent_product_id'];
}

I pretty new to Magento, so there might be better ways. Or reasons not to do this at all. Mainly the escaping/stripping the $id
