Using Magento 1.9.0.1 I am trying to programmatically create categories using a data upgrade script with the flat categories option turned on.

This first category I want to create is a new root category.

My data upgrade script looks something like this

$root_cat = array( ..Root Cat Data.. );

$store = Mage::app()->getStore();

$categories = Mage::getModel('catalog/category')
    ->getCollection()
    ->addAttributeToSelect('*')
    ->addIsActiveFilter();

$all_store_cat = array();

foreach ($categories as $_category) 
{
    $all_store_cat[] = $_category->getName();
}

if ( in_array($root_cat['name'], $all_store_cat) )
{
    echo 'Public Catalog already exists';
}
else
{
    echo 'Does not exist, lets create';

    $category = Mage::getModel('catalog/category');
    $category->setStoreId(Mage::app()->getStore()->getId());

        $data['path'] = '1'; // This is the path for root categorys
        // $data['setPosition'] = $root_cat['position'];

        $data['name'] = $root_cat['name'];
        $data['is_active'] = $root_cat['is_active'];

        $data['description'] = $root_cat['description'];

        $data['meta_title'] = $root_cat['meta_title'];
        $data['meta_keywords'] = $root_cat['meta_keywords'];
        $data['meta_description'] = $root_cat['meta_description'];
        $data['include_in_menu'] = $root_cat['include_in_menu'];

        $data['display_mode'] = $root_cat['display_mode'];
        $data['is_anchor'] = $root_cat['is_anchor'];

    $category->addData($data);

    // print_r($category);

    // die();

    $category->save();

    // unset($category);

    echo "created: " . $root_cat['name'] . "<br>";
}

I get the following error

Any help greatly appreciated, pulling my hair out over this one!

Ok I think I got it.

Replacing..

$store = Mage::app()->getStore();

..with..

$store = Mage::app()->setCurrentStore(Mage_Core_Model_App::ADMIN_STORE_ID);

..seems to have done the trick.

Create category dynamically:

$category = Mage::getModel('catalog/category');
$category->setStoreId(Mage::app()->getStore()->getId());

$cat['name'] = "Custom Category Name here";
$cat['path'] = "1/2/30"; //parent relationship..
$cat['description'] = "categorie's description";
$cat['is_active'] = 1;
$cat['is_anchor'] = 0; //for layered navigation
$cat['page_layout'] = 'two_columns_left';
$cat['url_key'] = "custom-category"; //url to access this category
$cat['image'] = "custom-category.jpg";

$category->addData($cat);
$category->save();

Then reindex catalog_category_flat dynamically:

$process = Mage::getSingleton('index/indexer')->getProcessByCode('catalog_category_flat');
$process->reindexEverything();
