How can i export fields like category name not category id via Dateflow-profiles export

Question

I need to get my all products category name, actually dataflow profiles return category id only, how can i get category name not category id.

Answer 1

In addition to B G Kavinga's answer, to get full category path like books/cheldreans/Tamil Books use below code.

public function unparse()
{
    $entityIds = $this->getData();
    foreach ($entityIds as $i => $entityId) {

            'type'          => $product->getTypeId(),
            'category_ids'  => join(',', $product->getCategoryIds()),
            'category_names' => join(',', $this->get_values_for_keys($categoryFullPaths, $product->getCategoryIds()))

Answer 2

There are 2 options.

1. Rewrite Mage_Catalog_Model_Convert_Parser_Product and update unparse() as below.
2. Create new parser by extending Mage_Catalog_Model_Convert_Parser_Product and update unparse() as below. Then update action xml to use new parser.

Updated Code

/** @var array $categoryNames Retrive category name */
            $categoryNames = $product->getCategoryCollection()
                ->addAttributeToSelect('name')
                ->getColumnValues('name');

            $row = array(
                'store' => $this->getStore()->getCode(),
                'websites' => '',
                'attribute_set' => $this->getAttributeSetName($product->getEntityTypeId(),
                    $product->getAttributeSetId()),
                'type' => $product->getTypeId(),
                'category_names' => join(',', $categoryNames)
            );
