Get Configurable Product (or) Associated Product details in Magento Product page

In this post, I’ll explain about how to get Configurable/associated/grouped product details in Magento product page?

//Note: In the below code if there is any ` (bactics) symbol, replace it to single quotes. 

$conf_pro = Mage::getModel('catalog/product')->load($_product->getId());
$childProducts = Mage::getModel('catalog/product_type_configurable')->getUsedProducts(null,$conf_pro); 

//print_r($childProducts); // Print and see the array indexes and fetch details according to your requirement 
foreach($childProducts as $child) { echo $child['name'];} 

//Get the configurable attribute name of the product in product view page:

$configurable = $_product->getTypeInstance();
$attributes = $configurable->getConfigurableAttributes($_product);
foreach ($attributes as $attribute) {
    print $attribute->getLabel();
    print "<br />";
}
           

实例2： 

<?php $_product = $this->getProduct(); ?>
<?php
$children = array();
$childProducts = Mage::getModel('catalog/product_type_configurable')->getUsedProducts(null,$_product);
foreach($childProducts as $child):
	$qty  = (int)Mage::getModel('cataloginventory/stock_item')->loadByProduct($child)->getQty();
	$size = $child->getResource()->getAttribute('size')->getFrontend()->getValue($child);
				
	$children[$size]['title'] = $child->getName();
	$children[$size]['size']  = $size;
	$children[$size]['qty']   = $qty;
endforeach;
	
echo '<pre>'; print_r($children); echo '</pre>';  die;
?>
