Magento - how do I get associated products of product Group?

Question

I am looping through products results, and if the product is a grouped product, I want to get all products in that group. I\'m doing this:

$products = Mage::getM

In:

/magento/app/design/frontend/base/default/template/catalog/product/view/type/grouped.phtml

You'll see that they use this:

getAssociatedProducts();

Since that phtml file is of type Mage_Catalog_Block_Product_View_Type_Grouped, we can go to:

/magento/app/code/core/Mage/Catalog/Block/Product/View/Type/Grouped.php

and see that Mage_Catalog_Block_Product_View_Type_Grouped::getAssociatedProducts() does this:

getProduct()->getTypeInstance()->getAssociatedProducts($this->getProduct());

So we can safely assume that $this->getProduct() returns a product object, and replace it with your $product variable like so:

getTypeId() == 'grouped'){
        // how do I now get associated products of $product?
        $associatedProducts = $product->getTypeInstance()->getAssociatedProducts($product);
    }

If I was to optimise your code completely, I'd write it like this:

getCollection()
        ->addAttributeToFilter('type_id', array('eq' => 'grouped'));
    foreach ($products as $product) {
        $associatedProducts = $product->getTypeInstance()->getAssociatedProducts($product);
        // Do something with $associatedProducts
    }
