How can I programatically set the categories AND the sort order/position of products? I already have an exisiting script that iterates through my products and assigns the categories $product = Mage::getModel('catalog/product'); $product->setData($my_array_with_a_lot_of_data_including_arrayCategoryIds); $product->save();

However, this set's the sort order/position for all products to "1". I also have found this posting How to update product position (number) in specific category programmatically but I'd like to avoid loading every single category and do something like $product->setPosition($my_products_position);

Is there a way that does not require loading every single category?

PS: I want to assign the same position in every category.

You can do that writing directly to the database below is a working code that do that using an array of categories products

You have to create the array like this

            $categoryPosition[] = array('product_id' => $mageProduct->getId(),
                                        'category_id' => $categoryId,
                                        'position' => $position);

an run this code

foreach ($categoryPosition as $position){                        
            //print "Position: c=".$position['category_id']." prod=".$position['product_id']." pos=".$position['position'] . "\n";
            $query = "UPDATE tn_catalog_category_product SET position = :position "
                    . "WHERE category_id = :category_id and product_id = :product_id";
            $values = array('position' => $position['position'],
                                'category_id' => $position['category_id'],
                                'product_id' => $position['product_id']);
            $writeConnection->query($query,$values);                    
}

and remember to run the indexer catalog_category_product

Thanks

There is no way of doing this, because it is harcoded here: app/code/core/Mage/Catalog/Model/Resource/Product.php:279

To change this you need to either rewrite the resource model or do a second save somehow...
