Add a simple to a configurable automatically

Question

i´ve got a code like this:

$product_config = new Mage_Catalog_Model_Product_Type_Configurable();
$product_config->setProduct($product_grouped);
$assigned_products = $product_config->getUsedProducts();

So i create a new config, set the product and get all used products.

Here´s my problem: I want to add another product to the "list" of "used Products", so when I save the product later, the new product should also be added as new "configurable option" with a new price.

With Grouped Products it was much easiert, but i can´t find any way to do this also with a configurable product :(

Thanks for Help!

You can use the product configurable type resource model to add a simple product to a configurable, e.g.:

$configurableId = 135;
$simpleId = 91;
$configurableProduct = Mage::getModel('catalog/product')->load($configurableId);

$simples = $configurableProduct->getTypeInstance('configurable', $configurableProduct)
    ->getUsedProductIds();
$simples[] = $simpleId;

Mage::getResourceModel('catalog/product_type_configurable')
    ->saveProducts($configurableProduct, $simples);
