To correctly filter and handle array-like structures in Shopify Liquid, you can use a combination of Liquid's built-in filters and loops. Here's a detailed solution with examples:

1. Filtering Array-Like Structures

You can filter array-like structures using the where filter in Shopify Liquid. This filter helps you to filter items based on a specific property.

Example:

Let's say you have a collection of products and you want to filter products that are available. (available is true).

{% assign available_products = products | where: "available", true %}
2. Looping Through Filtered Arrays

Once you have filtered the array, you can loop through it using the for loop.

Example:

Continuing from the previous example, let's loop through the available_products and display their titles.

{% assign available_products = products | where: "available", true %}

<ul>
  {% for product in available_products %}
    <li>{{ product.title }}</li>
  {% endfor %}
</ul>

Using Additional Filters You can use additional filters to further manipulate the array-like structures, such as sort, reverse, slice, etc.

Example:

Sort the available products by title and then display them.**

{% assign available_products = products | where: "available", true | sort: "title" %}

<ul>
  {% for product in available_products %}
    <li>{{ product.title }}</li>
  {% endfor %}
</ul>

4. Handling Empty Arrays

It's good practice to handle cases where the array might be empty to avoid displaying empty HTML elements .

Example:

Check if the available_products array is empty before displaying the list.

{% assign available_products = products | where: "available", true | sort: "title" %}

{% if available_products.size > 0 %}
  <ul>
    {% for product in available_products %}
      <li>{{ product.title }}</li>
    {% endfor %}
  </ul>
{% else %}
  <p>No available products found.</p>
{% endif %}

5. Combining Filters

You can combine multiple filters to achieve complex filtering.

Example:

Filter products that are available and belong to a specific vendor, then sort them by price.

{% assign vendor_products = products | where: "vendor", "Specific Vendor" %}
{% assign available_vendor_products = vendor_products | where: "available", true | sort: "price" %}

{% if available_vendor_products.size > 0 %}
  <ul>
    {% for product in available_vendor_products %}
      <li>{{ product.title }} - {{ product.price | money }}</li>
    {% endfor %}
  </ul>
{% else %}
  <p>No available products from this vendor found.</p>
{% endif %}

By using these techniques, you can effectively filter and handle array-like structures in Shopify Liquid, making your templates more dynamic and responsive to the data they process.
