How do I loop through schema id's that have incrementing index?

Technical Q&A
1

I want to display a slider/carousel above the header navigation. The code can be edited inside header.liquid. The contents of the slider are configured via {% schema %}{% endschema %}

header.liquid


      {% for i in (1..3) %}
        {% assign announcement_text = "announcement_text_" | append: forloop.index %}

        
          {{ section.settings.[announcement_text] }}
        
      {% endfor %}
  

{% schema %}
  {
    "name": "Header",
    "settings": [
    {
      "type": "richtext",
      "id": "announcement_text_1",
      "label": "Text 1",
      "default": "

Announcement 1

"
    },
    {
      "type": "richtext",
      "id": "announcement_text_2",
      "label": "Text 2",
      "default": "

Announcement 2

"
    },
    {
        "type": "url",
        "id": "announcement_url_1",
        "label": "Announcement Link 1"
    },
    {
        "type": "url",
        "id": "announcement_url_2",
        "label": "Announcement Link 2"
    },
    ],
    "blocks": [
    {
      "type": "sub_menu",
      "name": "sub_menu",
      "settings": [
        ....
      ]
    }
    ]
  }
{% endschema %}

As you can see on the Schema and code above, I am trying to loop through the announcement_text_1 and announcement_text_2 id’s via the announcement_text variable since it has an incrementing index.

Problem: I am prompted with Liquid syntax error (line 60): Expected id but found open_square in "{{ section.settings.[announcement_text] in my terminal.

Do you know what should be the correct syntax for section.settings.[announcement_text]?

Any help is greatly appreciated. Thank you.

Hello @redshot !
You have a small mistake in your code - you don’t need to use a dot and square brackets at the same time when referring to ID. In this case, you should use the expression:

{{ section.settings[announcement_text] }}

Hope I solved your problem) :slightly_smiling_face: Have a good day!
