Get category name in php feed Magento with main and subcategories - magento

Question

We have a producfeed for Magento that is made in php and is making an .xml productfeed. In the image below you can see how we run the loop to get the products in the xml feed. We are also getting the categories with the following code:
//Prepare the loop
foreach($prodIds as $productId) {
$product->load($productId);
$product_data = array();
//Get product data
$product_data['title']=$product->getName();
$product_data['description']= strip_tags($product->getDescription());
$product_data['sku']=$product->getSku();
$product_data['color']=$product->getResource()->getAttribute('color')->getFrontend()->getValue($product);
if($product->getSpecialPrice())
$product_data['price']=number_format($product->getSpecialPrice(), 2);
else
$product_data['price']=number_format($product->getPrice(), 2);
$product_data['specialprice']=number_format($product->getSpecialPrice(), 2);
$product_data['old_price']=number_format($product->getPrice(), 2);
$product_data['availability']="Op voorraad";
$product_data['shippingcost']="6.95";
$product_data['delivery_time']="2 tot 5 werkdagen";
$product_data['link']=Mage::getBaseUrl().$product->getUrlPath();
$product_data['image_link']=Mage::getBaseUrl(Mage_Core_Model_Store::URL_TYPE_MEDIA).'catalog/product'.$product->getImage();
$product_data['image_link_small']= Mage::helper('catalog/image')->init($product, 'small_image')->resize(200,200);
//Get feed category data
$childIds = Mage::getModel('catalog/product_type_configurable')->getChildrenIds($product->getId());
// Echo run the loop
?>
<product>
<sku><![CDATA[<?php echo $product_data['sku'] ?>]]></sku>
<link><![CDATA[<?php echo $product_data['link'].$source ?>]]></link>
<title><![CDATA[<?php echo $product_data['title'] ?>]]></title>
<description><![CDATA[<?php echo $product_data['description'] ?>]]></description>
<image_link><![CDATA[<?php echo $product_data['image_link'] ?>]]></image_link>
<image_link_small><![CDATA[<?php echo $product_data['image_link_small'] ?>]]></image_link_small>
<price><![CDATA[<?php echo $product_data['price'] ?>]]></price>
<old_price><![CDATA[<?php echo $product_data['old_price'] ?>]]></old_price>
<availability><![CDATA[<?php echo $product_data['availability'] ?>]]></availability>
<delivery_time><![CDATA[<?php echo $product_data['delivery_time'] ?>]]></delivery_time>
<id><![CDATA[<?php echo $product_data['sku'] ?>]]></id>
<delivery_costs><![CDATA[<?php echo $product_data['shippingcost'] ?>]]></delivery_costs>
<special_price><![CDATA[<?php echo $product_data['specialprice'] ?>]]></special_price>
<categories><?php $categoryCollection = $product->getCategoryCollection()->addAttributeToSelect('name');?><?php foreach($categoryCollection as $cat): ?><subcat><?php echo htmlentities($cat->getName()); ?></subcat><?php endforeach; ?></categories>
</product>
<?php } //End of loop ?>
</products>
Now we want to make a difference between the main categories and the subcategories. With the code above we get a list with all categories and it should be two fields, one with main categories and one with subcategories.
Can someone help me modify the code?

Answer 1

You can check if a category is top category by it's level.
if ($category->getLevel() == 2){
//is top category
}
elseif ($category->getLevel() > 2){
//is subcategory
}
and next time post the code, not the screenshot. What is this, a question for ants? :)
