I needed to get the parent sku of a grouped product. When a grouped product is added to the cart, only the individual items are stored, so the individual product skus are available, but not the parent sku.

<?php
// Start the Magento application without controller
require_once 'app/Mage.php';
Mage::app();

// Get magento frontend core/session Singleton
Mage::getSingleton('core/session', array('name'=>'frontend'));

// Get checkout session Singleton
$session = Mage::getSingleton('checkout/session');

// Use singleton method to get all items in cart
$cart_items = $session->getQuote()->getAllItems();

// Iterate through cart items


foreach( $cart_items as $item ) {
    // Normal product data
    $sku = $item->getSku();
    $qty = $item->getQty();
    $price = $item->getBaseCalculationPrice();
    $name = $item->getName();
    $item_id = $item->getItemId();


    // Get parent sku via parent_id
    $values = unserialize($item->getOptionByCode('info_buyRequest')->getValue());
    $parent_id = $values['super_product_config']['product_id'];
    $product_details = Mage::getModel('catalog/product')->load($parent_id)->getData();
    $parent_sku = $product_details['sku'];

    echo "SKU: $sku<br />";
    echo "PARENT_SKU: $parent_sku<br /><br />";
}
?>

1) Copy the Category.php file from core to local. Create any directories required under app/code/local. (This is so images can be displayed):

$ cp app/code/core/Mage/Catalog/Model/Resource/Eav/Mysql4/Category.php app/code/local/Mage/Catalog/Model/Resource/Eav/Mysql4/Category.php

2) Add -addAttrbuteToSelect('image') to getChildrenCategories function:

    public function getChildrenCategories($category)
    {
        $collection = $category->getCollection();
        /* @var $collection Mage_Catalog_Model_Resource_Eav_Mysql4_Category_Collection */
        $collection->addAttributeToSelect('url_key')
            ->addAttributeToSelect('name')
            ->addAttributeToSelect('image')
            ->addAttributeToSelect('all_children')
            ->addAttributeToSelect('is_anchor')
            ->addAttributeToFilter('is_active', 1)
            ->addIdFilter($category->getChildren())
            ->setOrder('position', 'ASC')
            ->joinUrlRewrite()
            ->load();
        return $collection;
    }

3) Add or modify the category view template app/design/frontend/yourdiractory_path/default/template/catalog/category/view.phtml:

<?php
$_category  = $this->getCurrentCategory(); 
$collection = Mage::getModel('catalog/category')->getCategories($_category->entity_id);

$rootcat = $_category->entity_id;
$cat = Mage::getModel('catalog/category')->load($rootcat);
$child = $cat->getChildren();

if($child)
{
$helper     = Mage::helper('catalog/category');
$_helper    = $this->helper('catalog/output');
?>
<div class="category-custom-products">
        <span class="page-title">
        <?php echo $_helper->categoryAttribute($_category, $_category->getName(), 'name') ?></span>

<div class="products-grid">

    <?php foreach ($collection as $cat):?>
        <?php if($_category->getIsActive()):?>
        <?php 
            $cur_category = Mage::getModel('catalog/category')->load($cat->getId());
            //echo $cat->getId();
            $_img = $cur_category->getImageUrl();  
        ?>

<div class="item">
                    
                    getName();?>
</div>                
                
                <?php endif?>
    <?php endforeach;?>
    
</div></div>
<?php
}
else
{
?>
    <?php echo $this->getProductListHtml() ?>
<?php
}
?>

The href tags are getting wonked out by the editor, I'll try and fix them when I get a chance.

Apparently I'm not alone, as Googling gave me dozens of results, all which were of no help...until I came across the post on stackoverflow:

"I found the solution to this problem after deeply looking at the log file.

Although I created my own Distribution Profile and assigned to the CODE SIGNING IDENTITY the correct value for the developer certificate, it didn't work giving me an error: "Application failed codesign verification".

The problem is at the following line:

Authority=iPhone Developer: My Name (XXXXXXXXX)

Despite the correct selection in the project settings for the Distribution profile, XCode was compiling it with the developer certificate.

I finally solved it: Right click on the "Targets" -> Get info -> and there it was selected (don't ask me why) the wrong distribution certificate instead of the right one.

I corrected that and it finally was accepted."

Thanks to Cy for answering his own, and my question...
