Get product ID in Bundle selection dropdown

Question

I'm using bundle products, and want to get the ID of simple products.

I was trying to get the ID from the product selection, but I think it's impossible.

My code:

<?php foreach ($_options as $_option): ?>
<?php
$_selections = $_option->getSelections();
foreach ($_selections as $_selection) {
    $id = $_selection->getProductId();          
    $product = Mage::getModel('catalog/product')->load($id);

    $descripcion = $product->getDescription();
    $descriptions[ $id ] = $descripcion;
}
?>

But the $_selection->getProductId() its the product ID SELECTION, not the product ID from catalog.

Any idea?

Answer 1

you can get the ids of the bundle items like this:

$mainProductId = your bundle product id here
$children = Mage::getResourceModel('bundle/selection')
                 ->getChildrenIds($mainProductId, false);

$children will be an array like this:

Array
(
    [0] => Array
        (
            [1] => 1
            [5] => 5
        )

    [1] => Array
        (
            [2] => 2
        )

)

The first index in the array (0, 1) is a numerical index for each option and the second dimension holds the product ids (1,5 for the first one, 2 for the second option)

Here we go..

    <?php

    require_once('app/Mage.php');

    Mage::app();

    // Get bundle product
    $product=Mage::getModel('catalog/product')->load('2');
    $selections = $product->getTypeInstance(true)
                ->getSelectionsCollection($product->getTypeInstance(true)
                ->getOptionsIds($product), $product);

    // get Selections
    foreach ($selections as $selection) {
    // Fetch information from selection
    print_r($selection->getId());
    }
?>
