How can I sort a nested array by product type?

[kampotix]

Here's my code:

{% for line_item in line_items | sort: "line_item.product.type" %}
      <tr>
        <td>{{ line_item.quantity }} x</td>
        <td><b>{{ line_item.title }}</b></td>
        {% if show_line_item_taxes %}
        <td>
          {% for tax_line in line_item.tax_lines %}
            {{ tax_line.price | money }} {{ tax_line.title }}<br/>
          {% endfor %}
        </td>
        {% endif %}
        <td>
          {% if line_item.original_price != line_item.price %}
            <s>{{ line_item.original_price | money }}</s>
          {% endif %}
          {{ line_item.price | money }}
        </td>
        <td>{{ line_item.product.type }}</td>
      </tr>
    {% endfor %}

I need to sort by product type (Category). Thank you.

Hi there,

You can try something along these lines, it should accomplish what you want. It's not pretty but not ugly either, I'm also curious to know if there's a way to filter/sort nested properties more efficiently, but Im' not aware of it :

{% assign line_items = cart.items %}
{% assign types = line_items | map: 'product' | map: 'type' | sort_natural | uniq %}
{% for type in types %}
  {% for line_item in line_items %}
    {% if line_item.product.type == type %}
      your code...
    {%  endif %}
{% endfor %}
{% endfor %}

So basically, I take the problem differently. I first make a list of all product types in the cart, sort them alphabetically, and remove the duplicate types. We loop through each type, and then loop through each line_item inside of that, which allow us to filter out line_items types that are not matching the type from the main loop.

It works, thank you very much!

I am trying to implement your solution, with no luck. I am using this code below to sort the packing slip alphabetically, but I want to further "group" by Product Type, and then sort alphabetically within each "group" of Product Type. 

{% assign lineitems = line_items_in_shipment | sort: "title" %}
{% for line_item in lineitems %} 

How would I integrate this with your solution? I tried to put my code in your code where it says "your code", but it returns a syntax error.
