Chapter 5, Diving into Liquid Core with Filters

Question 1

Suppose that we have an array named product_handles with handles of 30 products. What issue in the following code would prevent us from outputting the images of all 30 products successfully?

{% for handle in product_handles %}
  {% assign product_object = all_products[handle] %}
  {% for image_item in product_object.images %}
    <img src="{{ image_item | img_url }}"/>
  {% endfor %}
{% endfor %}

Answer

Since we are looking to output more than 20 products, in this case, 30 products, we cannot use the all_products object, as the all_products object has a limitation that we can only call it 20 times on a single page. If we are looking to recover data from more than 20 products, we need to assign them to a collection and then perform a loop over those products. We can remind ourselves of the all_products object by visiting the Working with HTML and URL...
