Displaying a List of Related Products

Displaying related products is a simple task, if you have followed our advice to create a separate partial for displaying a product list.

You can obtain a collection of related products with the list_related_products() method of the $product object. The following code demonstrates how you can output a list of related products using the partial you created before.

<?
  $related_products = $product->list_related_products()->find_all();
  if ($related_products->count):
?>
  <h3>Related products</h3>
  <? $this->render_partial('shop:product_list', array('products'=>$related_products)); ?>
<? endif ?>

{% set related_products = product.list_related_products().find_all() %}
{% if related_products.count %}
  <h3>Related products</h3>
  {{ render_partial('shop:product_list', {'products': related_products}) }}
{% endif %}

The code checks whether any related products were assigned to the current products and outputs the header “Related products”. Then it renders the shop:product_list partial passing a result of the list_related_products() method call as a collection of products into the product list partial.

You can duplicate the shop:product_list partial and modify it if you need another way of displaying the related products.
