Listing categories a product belongs to.

I understand that as long as products can belong to multiple categories, a return link to whatever category list a shopper used to view a product is a problematic request.

What I would like to add to the template is a collection of links to ALL of the categories to which a product belongs. The product item itself does not appear to contain that list. How would I go about grabbing that list so that I can build my own collection of links?

Thank you for your help! You led me to precisely the right places.

Here's the solution I'm going with for the moment (my customer has declared that each of his products will belong to only one category). I will be storing your information about the multiple categories for later use, because I am sure other customers' inventories will not be so well-defined.

I added this to the product->show template. It adds a 'Continue Shopping' button using the cart's current CSS style.

$link = hikashop_completeLink( 'category&cid=' . $this->element->category_id );
echo $this->cart->displayButton( JText::_('Continue Shopping'), 'category', $this->params, $link );

After digging into it, I changed my mind and decided to complete the multiple category option.

Here is the code:

  $productClass = hikashop_get('class.product');
  $productClass->getProducts( $this->element->product_id );
  $categories = $productClass->products[ $this->element->product_id ]->categories;

  if( is_array( $categories ) AND count( $categories ) )
  {
    foreach( $categories as $c )
    {
      $categoryClass = hikashop_get('class.category');
      $category = $categoryClass->get( $c );

      $link = hikashop_completeLink( 'category&cid=' . $category->category_id );
      echo $this->cart->displayButton( JText::_('Return to ' . $category->category_name ), 'category' . $category->category_id, $this->params, $link );
    }
  }
