在Magento的产品比较页面上获取产品ID？

Question

I would like to separate some attributes according to product category ID. I am getting all the attributes on : app/design/frontend/mytheme/default/catalog/product/compare/list.phtml page.

I can get attribute value using

$this->helper('catalog/output')->productAttribute($_item, $this->getProductAttributeValue($_item, $_attribute), $_attribute->getAttributeCode())

but how to get product category ID?

How to get current product id

Try below code to get currently loaded product id:

$product_id = $this->getProduct()->getId();

When you don't have access to $this, you can use Magento registry:

For categories do like this :

$product = Mage::getModel('catalog/product')->load($product_id);

$cats = $product->getCategoryIds();
foreach ($cats as $category_id) {
    $_cat = Mage::getModel('catalog/category')->load($category_id) ;
    echo $_cat->getName();
}
